Our duct coolers/heaters can operate with water or glycol as the heat transfer medium and are fully compatible with both heat recovery (HRV/ERV) and standalone ventilation systems. The robust construction, high efficiency, and flexible installation make them the ideal solution for maintaining optimal indoor air temperature in any project.
AirHC1000
Advanced Duct Coolers/Heaters
GHT duct coolers and heaters with circular connections (DN250) are designed to deliver reliable and energy-efficient climate control for a wide range of ventilation systems. These units are suitable for both residential and commercial applications, as well as controlled environment agriculture (CEA) projects such as greenhouses and indoor farms.
Possible Applications of AirHC1000
AirHC1000 is developed for versatile use in various air handling and ventilation solutions, thanks to its high efficiency, broad temperature range, and robust construction.
Flexible Integration
The AirHC1000 post-heater/cooler is designed for maximum flexibility and can be efficiently integrated both downstream of a heat recovery (HRV/ERV) unit or used independently on supply air duct alongside fan.
Enhanced Air Quality with Filter Integration:
The unit has two compartments for air filters, providing an option for air filter integration
With Heat Recovery Unit:
When installed after a ventilation heat recovery unit, AirHC1000 serves as a “post-heater” or cooler. It ensures the supply air temperature reaches the desired comfort level, regardless of the efficiency of the heat exchanger in the HRV. This is especially important during extreme outdoor temperatures, or when additional cooling is needed in summer.
Operation in Cold Climates – Why Use Glycol?
Important: In regions where winter temperatures regularly fall below 0°C (32°F) and no heat recovery unit installed, it is essential to use a glycol solution (antifreeze) as the heat transfer medium in the AirHC1000 unit. Glycol protects the internal heat exchanger from freezing and subsequent damage, ensuring:
- Safe, reliable operation even in prolonged frost or during ventilation shutdowns.
- Extended equipment lifetime and reduced maintenance risks.
In moderate or warm climates, plain water can also be used as the heat carrier. However, for maximum safety, especially in areas subject to sudden temperature changes or for seasonal homes with prolonged absence, glycol is always recommended for freeze protection.
