Summer By-Pass
The Zehnder Q range of units have a 100% summer by-Pass
Low Noise Levels
With airtight, aerodynamic and sound absorbing construction with perfectly balanced fans the noise levels are ultra quiet
Heat Exchanger
The Highest performing heat recovery exchanger that can recover up to 96% of otherwise lost heat
Frost Protection
The unit has a frost protection programme
Optional Pre Heater
The intelligent pre-heater adapts its operation taking into consideration temperature, air flow and humidity to ensure consistent supply air temperature is achieved no matter what is going on outside. Thanks to its large surface and delta shape, the level of pressure loss is negligible – and that also reduces the power consumption for the best possible energy efficiency
Orientation
The Standard unit can be changed from Left- or right-hand configuration through software alone, with no mechanical alteration or alternative configuration of unit is required
The Heater units can be right or left-handed and correct orientation should be checked before purchase
Mounting
The units are supplied with a wall mounting bracket and there is an optional floor stand
