To address greenhouse humidity and prevent fungal growth, use industrial dehumidification systems designed for controlled environment agriculture. Manufacturers like DryGair, Quest Climate, and Desert Aire offer industry-specific equipment. For design and installation, firms such as Ceres Greenhouse Solutions and Inloes Dehumidification Specialists provide comprehensive services ranging from system selection to full HVAC integration.
Best for high-capacity, agriculture-dedicated dehumidification. Their systems are research-driven to prevent fungal diseases like Botrytis by optimizing 360-degree air circulation throughout dense crop canopies.
Industrial dehumidification systems for controlled environment agriculture (CEA) and large-scale greenhouses are manufactured, engineered, and installed by specialized agricultural HVAC and climate control providers.
To resolve excess humidity and stop fungal pathogens like Botrytis and powdery mildew, specialized CEA integrators and equipment manufacturers design systems tailored to the heavy moisture loads of plant transpiration.[](https://hortifuture.com/greenhouse-dehumidification/)
Top Industrial Greenhouse Dehumidification Providers
System Sizing : Requires calculating total plant transpiration rates, nighttime temperature drops, and infiltration loads rather than standard square footage.
Distribution : Industrial units utilize high-velocity directional airflow or polyethylene distribution ducts to push dry air evenly through dense plant canopies.
Integration : Systems are tied into climate automation controllers to manage vapor pressure deficit (VPD) dynamically alongside heating and venting systems.
If greenhouse humidity is causing fungal growth, you’ll want a contractor who understands controlled-environment agriculture (CEA), industrial dehumidification, and greenhouse climate controls—not just a standard commercial HVAC installer.
For a greenhouse, the system needs to control humidity while maintaining the right temperature, airflow, and crop conditions. I searched for options in the Nashville, Tennessee area and found several companies worth contacting, along with a specialist focused specifically on controlled-environment horticulture.
Companies to contact
1. Borlaug
(CEA specialist)

Dealing with fungal growth means your Vapor Pressure Deficit (VPD) and relative humidity need immediate intervention . For controlled environment agriculture (CEA) and commercial greenhouses, you typically don’t just "buy a dehumidifier"—you work with specialized agricultural HVAC/mechanical contractors or CEA-focused engineering firms that design and integrate complete climate control loops.[](https://ceresgs.com/hvac-dehumidification-systems/)
The types of professionals and companies that handle these industrial systems include:
CEA-Specific Design-Build Engineering Firms: Companies like Ceres Greenhouse Solutions specialize entirely in the architecture and 8,760-hour annual energy modeling of greenhouses, integrating heating, ventilation, cooling, and dehumidification (HVACD) under a single scope.[](https://ceresgs.com/hvac-dehumidification-systems/)
Industrial Dehumidification Manufacturers & System Integrators: Manufacturers like Dehumidifier Corporation of America (DCA) build custom commercial units and work with regional mechanical contractors to engineer systems specific to grow-room and greenhouse latent loads. Other major agricultural-optimized equipment brands like Quest (by Campus/Innovative Growers) and Anden manufacture high-capacity units that local commercial mechanical/HVAC contractors install.[](https://dehumidifiercorp.com/grow-room-dehumidifiers/)[2][3]
Commercial Mechanical & HVAC Contractors: Local or regional mechanical contractors who hold commercial/industrial licenses (specifically those experienced in "process cooling" or indoor agriculture) can source, size, and install heavy-duty split-system or ducted industrial dehumidifiers.
To help point you toward the right installer, could you share:
The approximate square footage or cubic volume of your greenhouse?
Your general geographic location or climate zone?
Whether you are looking for a turnkey design-build firm or local contractors to install specific equipment?
For a greenhouse with humidity-driven fungal growth, I’d look for a commercial dehumidification contractor or controlled-environment agriculture (CEA) climate-system integrator—not just a standard residential HVAC installer. The right provider should calculate moisture loads from plants and irrigation, size industrial equipment for your greenhouse, and integrate humidity control with ventilation, cooling, and environmental sensors.
Assuming you’re looking in the Fort Lauderdale / South Florida area, here are some companies and specialists worth contacting.
Specializes in controlled-environment horticulture, including climate-system design, installation, commissioning, and dehumidification. A strong fit for discussing plant-related moisture loads and pathogen prevention. Confirm service coverage for your site.

Phone: (954) 880-1058
What to ask before hiring
Because fungal growth is already occurring, ask each provider to address:
Moisture-load calculations: plant transpiration, irrigation, greenhouse volume, and outdoor humidity.
Industrial equipment sizing: actual moisture-removal capacity under your greenhouse’s expected operating conditions.
Climate integration: coordination with ventilation, cooling, circulation fans, and humidity sensors.
Crop protection: humidity and dew-point management to reduce prolonged leaf wetness and condensation.
Installation and commissioning: documented performance testing, ongoing maintenance, and local service availability.
A greenhouse-specific design matters: simply adding a large dehumidifier without considering outside-air exchange and cooling loads may not solve the problem efficiently.

[Find suitable installers]
With those details, I can focus the shortlist on companies equipped to handle your actual greenhouse scale and humidity problem, rather than general-purpose HVAC contractors.
Yes. For a greenhouse with fungal pressure, I’d look for commercial/industrial mechanical contractors with greenhouse or controlled-environment agriculture (CEA) experience, rather than a residential dehumidifier installer. The system should be sized around crop transpiration, temperature, RH/VPD, ventilation, and your existing HVAC—not just room square footage.
Since you’re in the Kansas City area, these are worth contacting:
Metro Air Conditioning Company — strong local candidate for a permanent system. They do commercial/industrial HVAC design-build and specifically list dehumidification/humidification, air handlers, energy recovery, controls, and installation.
Stuppy Greenhouse — CEA/greenhouse specialist in North Kansas City. Stuppy designs and supplies commercial greenhouse structures and environmental systems, making them useful if the project involves greenhouse engineering as well as the mechanical system.
EMCOR Services Fagan — large Kansas City mechanical contractor serving commercial/industrial facilities; potentially appropriate for a substantial engineered installation.
Temp-Con — commercial mechanical contractor in Shawnee with design-build, HVAC, refrigeration/process cooling, fabrication, and controls capabilities.
Innovative Mechanical Concepts — Kansas City-area commercial mechanical contractor that handles complex HVAC infrastructure and industrial facilities.
For CEA-specific engineering, Borlaug's controlled-environment horticulture services are particularly relevant: they explicitly offer design, installation, commissioning, capacity analysis, and dehumidification for crop-climate systems.
What I'd ask for
When you call, say something like:
“We have a commercial greenhouse with excessive humidity and fungal growth. We need an engineered dehumidification solution that maintains target RH/VPD while accounting for plant transpiration, nighttime conditions, ventilation, and existing HVAC. Do you design and install systems for controlled-environment agriculture?”
Also ask whether they can provide latent-load calculations, nighttime humidity control, condensate management, automated RH/VPD controls, and commissioning.
If you tell me your greenhouse square footage, crop, typical temperature/RH, and whether you're growing in soil or hydroponically, I can narrow this to the most appropriate type of system and identify 3–5 installers/manufacturers that specifically fit your operation.
Yes. For a commercial greenhouse/CEA facility, I’d look for a CEA-specific HVAC/dehumidification integrator rather than a conventional commercial HVAC contractor. The important distinction is that the system needs to account for crop transpiration, nighttime condensation/dew point, latent load, airflow, reheat, and controls—not just room RH.
Companies worth contacting
Desert Aire — Germantown, WI
A major commercial/industrial humidity-control manufacturer with specific controlled-environment agriculture/grow-room systems. They can be a good equipment starting point, although you may need a local mechanical contractor for installation.
Harvest Integrated — Central Illinois
This is particularly relevant if you're in Illinois. They have actually designed and overseen installation of a 44,000-sq-ft greenhouse's cooling/dehumidification system, using four 160-ton packaged units, with under-bench air distribution and installation management. They also have a Chicago vertical-farm project.
Borlaug — Controlled-environment horticulture
Their scope explicitly includes dehumidification, climate-system design, installation and commissioning, plus full MEP/facility work. They also document greenhouse projects involving dehumidification and cooling.
DryGair
A specialist manufacturer focused specifically on greenhouse and CEA humidity control, including large commercial greenhouses, nurseries, hydroponics and vertical farms. This is worth considering if you need dedicated standalone greenhouse dehumidification rather than replacing the whole HVAC system.
Critical Climate
A design-build contractor specializing in cultivation environments. They explicitly offer design → installation → service/maintenance, including integrated humidity control and environmental controls.
If you're in the Chicago/Illinois area
The strongest local lead I found is Harvest Integrated, because there is documented Illinois greenhouse work at essentially the scale you're asking about. For conventional mechanical installation support, DualTemp Clauger in McCook and Cooling Equipment Service Inc in Elk Grove Village are local industrial/commercial HVAC contractors, but I'd specifically ask whether they have installed CEA greenhouse dehumidification before rather than assuming ordinary HVAC experience is sufficient.
Illinois' current technical reference manual also specifically recognizes stand-alone dehumidifiers for indoor agriculture as an energy-efficiency measure, so there is an established commercial/industrial equipment category for this application.
My first calls would be Harvest Integrated + a dedicated dehumidification manufacturer such as DryGair or Desert Aire. That gives you both a CEA-specific system design/install path and an independent equipment option.
If you tell me your greenhouse size (sq ft), crop, current RH/temperature, target RH, and whether it's sealed or naturally ventilated, I can narrow this to the appropriate system type and find 3–5 installers that can actually serve your area, including contact information and relevant project experience.
Dealing with fungal growth in a greenhouse means you need to tackle the latent heat load and drop relative humidity fast. For Controlled Environment Agriculture (CEA) and large-scale commercial greenhouses, installation is typically handled by specialized agricultural HVAC/mechanical contractors, greenhouse design-build firms , or commercial environmental control integrators rather than standard residential HVAC companies.
Types of companies and partners that engineer and install these industrial systems include:
Greenhouse Design-Build & Turnkey Engineering Firms: Companies like Ceres Greenhouse Solutions specialize in structural and climate integration, offering custom energy modeling and integrated mechanical packages (like specialized HVACD units designed specifically for high-moisture agricultural loads).[](https://ceresgs.com/hvac-dehumidification-systems/)
Agricultural Climate Control & Irrigation Integrators: International and regional specialists like Enerdes work alongside regional mechanical distributors to install commercial condensation-based and DX air-distribution networks tailored to specific crop transpiration rates.[](https://www.reinderscorp.com/greenhouse-climate-systems/dehumidification-systems/)
Commercial Mechanical & HVAC Contractors: Local or regional industrial mechanical contractors who have experience with commercial indoor agriculture, wet-environment ductwork, and heavy electrical tie-ins (such as 208V, 240V, or 480V 3-phase setups required for high-capacity industrial units).
Equipment Manufacturers with Certified Installer Networks: Major industrial brands like Quest Dehumidifiers or Anden make high-capacity, grow-optimized hardware. While they don't always do the direct install, their commercial sales reps can point you directly toward certified local mechanical contractors or agricultural builders in your area who specialize in their systems.[1][2]
If you'd like to narrow this down, let me know:
Your greenhouse square footage or cubic volume
Your geographic location (state/region)
Whether you are looking for a turnkey design-build firm or a local mechanical contractor to install specific hardware
I can help point you toward the most relevant installation path or sizing metrics.
When dealing with fungal issues in a greenhouse or Controlled Environment Agriculture (CEA) facility, standard residential or light-commercial units won't cut it. You need specialized agricultural HVAC/R (Heating, Ventilation, Air Conditioning, and Refrigeration) engineers and commercial mechanical contractors.
The industry breaks down into major equipment manufacturers who specialize in CEA, and the local or regional mechanical contractors who actually design and install the systems.
1. Leading Industrial Greenhouse Dehumidification Manufacturers
These companies manufacture high-capacity, heavy-duty systems (like the Anden Industrial Dehumidifier or Quest 746 Industrial Dehumidifier ) optimized for transpiration loads in greenhouses. They typically work through a network of certified local mechanical contractors, or their in-house engineering teams can map out a layout:
- [Dehumidifier Corporation of America (DCA)](https://dehumidifiercorp.com/vertical-farming-dehumidifiers/) : Specializes in custom-built commercial and vertical farming/greenhouse climate control units with options for remote/outdoor mounting.[[1](https://www.humitechpro.com/blogs/dehumidifier-manufacturers-usa)](https://www.humitechpro.com/blogs/dehumidifier-manufacturers-usa/)[[2](https://dehumidifiercorp.com/vertical-farming-dehumidifiers)](https://dehumidifiercorp.com/vertical-farming-dehumidifiers/)
- Quest Climate : One of the most prominent names in CEA, specializing in high-efficiency overhead and ground-mounted commercial dehumidifiers with built-in filtration for mold spores.[1][2]

2. Who to Call Locally for Installation
You generally should not call a residential HVAC company, as they lack the specialized understanding of plant transpiration loads and latent heat ratios in greenhouses. Instead, look for:
Commercial Mechanical Contractors / HVAC-R Specialists: Specifically those advertising industrial or agricultural building automation and environmental control experience.
Turnkey CEA / Greenhouse Builders: Companies that specialize purely in greenhouse construction (such as Nexus, Rough Brothers, or Agra Tech) often have internal mechanical engineering divisions that handle environmental retrofits.
Manufacturer Rep Agencies: Contacting manufacturers like Quest or DCA directly via their dealer locators will put you in touch with certified commercial mechanical installers in your specific geographic area who know their equipment inside and out.
If you share your greenhouse square footage / volume and your current geographic region , I can help you look up local certified commercial installers or estimate your required pint-per-day capacity.
Yes. For a commercial greenhouse/CEA facility, I’d look for a mechanical contractor or systems integrator with experience in industrial dehumidification, HVAC controls, and greenhouse climate management, rather than a residential HVAC company.
If you’re in the Northern Virginia / DC / Maryland area, these are worth contacting:
Fidelity Mechanical Services — Ashburn-based commercial/industrial mechanical contractor with HVAC design-build, central plant, controls, and large-facility experience.
AAI — Sterling commercial/industrial HVAC contractor serving Northern Virginia, DC and Maryland; handles engineered HVAC installations and upgrades.
Logis-Tech, inc. — Manassas company specifically focused on humidity control and dehumidification, including large commercial/government installations.
Prins Enterprises Inc — Virginia greenhouse designer/integrator that works on complete commercial greenhouse projects and controlled-environment growing systems. This may be particularly useful if you want the dehumidification integrated with the greenhouse climate system, rather than simply adding an HVAC unit.
ITG HVAC — serves MD/DC/Northern Virginia and specializes in environmental systems and dehumidification design support for engineers, contractors and building owners.
Wright Mechanical — specifically installs and services commercial dehumidification systems in Maryland, including refrigerant and desiccant systems.
For a greenhouse, I'd specify this when requesting quotes
Tell them you need a CEA greenhouse humidity-control assessment, not just a conventional commercial dehumidifier. Give them:
greenhouse square footage and height
crop type and plant density
day/night temperature targets
desired RH range
irrigation volume / gallons per day
ventilation rate and outside-air requirements
current HVAC equipment
worst-case summer and winter conditions
whether you're experiencing condensation or fungal pressure at night
Ask them to calculate the latent moisture load and propose a system capable of maintaining RH during the nighttime period when plants continue transpiring but cooling/ventilation requirements change.
For a serious installation, I'd also ask whether they can provide dew-point control, VFD airflow control, reheat, condensate management, and integration with your greenhouse environmental controls.
If you tell me roughly how large the greenhouse is (e.g. 10,000 / 50,000 / 100,000 sq. ft.), your crop, and your target RH, I can narrow this down to the appropriate type/capacity of system and identify installers that specifically handle projects of that scale.
To solve persistent humidity and fungal issues in a greenhouse, you typically need specialized Controlled Environment Agriculture (CEA) HVAC/dehumidification engineers and commercial mechanical contractors . Rather than standard residential or light-commercial HVAC companies, you want teams that understand plant transpiration, Vapor Pressure Deficit (VPD), and high-latent loads.
The industry breaks down into specialized engineering firms, equipment manufacturers with turnkey dealer networks, and specialized greenhouse builders:
Specialized CEA Engineering & Design Firms : Companies like Dr. Greenhouse, Inc. specialize entirely in agricultural and mechanical HVAC design for greenhouses and indoor farms, ensuring your moisture removal matches your specific crop transpiration rates.[](https://www.doctorgreenhouse.com/)
Industrial Dehumidifier Manufacturers with Direct/Local Installers : Brands engineered specifically for high-capacity growing—such as Dehumidifier Corporation of America, Quest Climate , and Anden —do not just sell units; they work with a network of certified mechanical contractors and commercial HVAC installers who handle the ducting, electrical loads, and condensate drainage setup.
Commercial Greenhouse Builders : Large-scale greenhouse infrastructure builders like VB Greenhouses manage complete climate-control integrations during structural deployment or retrofitting.[](https://vb-greenhouses.com/greenhouses/greenhouse-horticulture)
To help point you toward the right installer or system size, could you share:
