Van der Ende Group introduces the Airmix Active, a compact heat pump dehumidifier that expands the existing Airmix system with active climate control. This expansion creates a hybrid system that intelligently combines passive and active dehumidification. Van der Ende Group now offers growers the possibility of achieving an optimal greenhouse climate all year round: consistent, energy-efficient, and healthy. Fully tailored to the needs of the crop.
The well-known Airmix model T and G have been providing air mixing and passive dehumidification via air above the screen for many years. The Airmix Active adds active dehumidification via an integrated heating pump unit. This allows the greenhouse to be dehumidified even when the screen is closed, without heat loss through window gaps. The system automatically switches between passive and active dehumidification depending on temperature, RH, and absolute humidity. Passive where possible, active where necessary.
Smart and energy-efficient
The strength of the Airmix Active lies in its interaction with existing Airmix units. When the Airmix Active is actively dehumidifying, the standard Airmix units ensure an even distribution of dry air throughout the greenhouse. If air from above the screen is used, then, all units operate according to the familiar Airmix principle. This interaction results in an extremely efficient and energy-efficient way of climate control.
At a greenhouse temperature of 20 °C and 90% RH, one Airmix Active unit removes more than 18 grams of moisture per square metre per hour, based on an area of 1,600 m². This is achieved with a power consumption of only 5.3 watts per m² per hour, of which 4.2 watts is returned to the greenhouse as heat. This brings the net consumption to less than 1.1 watts per m².
New installation or upgrade of existing system
The Airmix Active is suitable for both new installations and existing greenhouses with Airmix model T or G. By replacing a couple of standard units or complementing them with Airmix Active units, you can create a hybrid system that automatically adapts to any weather type and climate condition.
“The Airmix Active completes the Airmix system,” says Micha van Nieuwkerk, CCO of Van der Ende Group. “Thanks to its compact design and smart integration with existing Airmix units, we achieve a uniform and healthy greenhouse climate all year round. And all this with minimal energy, fully tailored to the needs of the crop.”
First presentation at GreenTech
Van der Ende Group will present the Airmix Active for the first time at GreenTech 2025 in Amsterdam. Visit stand 01.411 and discover for yourself how the hybrid Airmix system contributes to year-round climate optimization in greenhouses.
