Evaporative cooling combines water and airflow. Exhaust fans draw outside air through a wet pad, where evaporation lowers its temperature before it crosses the greenhouse. Pad area, airflow, distribution and maintenance are sized for the local climate and humidity.

Better decisions. More value in every cycle.
How this equipment supports everyday crop management.
Less heat stress
Lower inlet air temperature when outdoor humidity allows evaporative cooling and sustain more favourable crop conditions.
More uniform conditions
A well-distributed airflow helps avoid undercooled areas and uneven growth within the greenhouse.
Less off-demand consumption
Coordinate pumps and fans with measured conditions to use water and electricity when cooling adds value.
Cooling starts at the wet pad
Exhaust fans draw outside air through a wet surface. Evaporation lowers its temperature and raises its humidity before the air crosses the greenhouse. Performance depends on incoming conditions, so local temperature and humidity are assessed before selecting the system.
Design the airflow path, not only the fan
Pads and fans are positioned to move air through the crop. Pad area, airflow, unintended openings and obstacles affect distribution. Design also includes water supply, recirculation, replenishment and access for cleaning and maintenance.
Operation coordinated with the environment
The system responds to agreed conditions and setpoints. Vents and screens must support the intended path; uncontrolled air entry can alter it. Indoor and outdoor measurements help review performance and adjust operation without treating an illustrative temperature as a guaranteed result.
Want to automate greenhouse cooling?
Integrate pads, pumps and exhaust fans with environmental conditions and management priorities.
Automatic functions depend on the sensors, actuators and configuration of each project.

Frequently asked questions
Which climates suit cooling pads?
Capacity depends on outdoor temperature and humidity. Greater evaporation potential allows a greater temperature reduction.
Does it add humidity?
Yes. Evaporating water lowers air temperature and increases humidity; both variables inform the operating strategy.
What does installation require?
Pads, fans, a water circuit, power and a suitable air path. Airflow, pad area and crop layout are sized together.
Does it run all night?
Not necessarily. Pumps and fans operate according to conditions and setpoints; they stop when there is no cooling demand.
What water-system maintenance is required?
Check water quality, filters, tanks, distribution and pad condition to limit deposits and blockages.
