Greenhouse Climate Control Systems
A greenhouse climate control system combines exhaust fans, evaporative cooling pads, circulation fans, controllers and thermal or shade screens so temperature, humidity and airflow stay within the crop’s target band. ClimaSpan helps plan the package from greenhouse size, structure type and crop goals, then quotes equipment by project.
Equipment selection and scope are confirmed in a written quote after we review your greenhouse size, layout, crop and climate. We do not publish public prices or catalogue-only spec sheets on these pages.
What the system does
- Moves hot, humid air out and pulls cooler air in through vents or a pad wall.
- Evaporative pads lower intake air temperature in hot weather when paired with exhaust fans.
- Circulation fans remix indoor air so conditions stay more even along the house.
- Controllers and screens coordinate fans, pads, vents and light/heat load when specified for the project.
Selection points
- Share length, width, eave/gutter height, cladding type and location.
- Describe crop, peak summer and winter goals, and any existing fans, pads or climate computer.
- We suggest a matched exhaust, pad and circulation layout; controllers and screens are scoped when your project needs them.
- Final models and quantities are confirmed only in a written quote.
How it pairs with structure and crops
- Film, glass and polycarbonate greenhouses — single-span or multi-span — can use the same climate logic with different mounting details.
- Vegetable, ornamental and nursery crops often need both air exchange (exhaust) and gentle in-house movement (circulation).
- Pad-and-fan layouts place pads opposite the exhaust wall; screens sit under the roof or gutter to manage light and heat load.
- Growing benches, hydroponic channels and irrigation affect sensor placement and airflow paths — send layout sketches when possible.
Climate control building blocks
Exhaust Fans
Negative-pressure air exchange for summer cooling and ventilation.
Cooling Pads
Evaporative intake cooling matched to exhaust capacity.
Circulation Fans
Horizontal mixing to reduce hot and humid pockets.
Controllers
Thermostats and climate computers that stage fans, pads and vents.
Screens
Shade and energy screens that cut heat load and night losses.

Benches change airflow under and over the crop.
Hydroponics
Soilless systems need stable climate around the root and canopy.
Irrigation
Irrigation timing interacts with humidity and leaf wetness.
Automation
Sensors and actuators that close the climate loop.
Frequently asked questions
What equipment is included in a ClimaSpan climate control package?
Typical packages start with greenhouse exhaust fans, evaporative cooling pads and circulation fans. Controllers and screens are added when your project scope includes them. Exact contents are listed in the written quote.
Do I need both exhaust fans and circulation fans?
For commercial summer cooling, yes in most houses: exhaust fans exchange indoor air with outdoor air; circulation fans remix air inside. Pad-and-fan cooling requires sized exhaust capacity.
Can this system fit an existing greenhouse?
Often yes. Send structure type, available wall openings, electrical supply and any existing fans or pads so we can plan a retrofit layout.
