■ Decorative radiators ■ Comfortable indoor ventilation ■ Heating and cooling ceiling systems ■ Clean air solutions X® zehv always the best climate

Advantages ■ Energy saving due to use of renewable energy from the ground ■ Maximum comfort due to pre-heating of outdoor air in winter using geothermal energy and temperature control of outdoor air in summer and winter for a comfortable indoor climate. ■ Compact, quick installation directly adjacent to the ventilation unit ■ Simple and sustainable use of geothermal energy with a low power consumption ■ Brine pump with energy efficiency class A ■ Air exchange in spite of low outdoor temperatures The Zehnder ComfoFond-L Q brine-earth heat exchanger has been developed for use in conjunction with...

Tender specification Zehnder ComfoFond-L Q brine-earth heat exchanger suitable for ComfoAir Q350/450/600 comfort ventilation units. In winter, the ComfoFond-L Q preheats the outdoor air before it enters the ventilation unit; in summer, it cools and dehumidifies the outdoor air. It is used as an extension option to the ComfoAir Q comfort ventilation unit, and can be installed compactly directly adjacent to the comfort ventilation unit. All necessary hydraulic components are included in the scope of delivery, such as the circulation pump, expansion tank, filling and flushing system, manometer and...
