Product description
 

 

Maintaining the climat in premises, with minimum energy consumption is major factor in operation cost management of the buildings. High efficiency heat recovery installations provide fresh air supply  with temperature, similar to that  in the room. The need of additional heater is minimized.

 

 

 

 

 

Product range
 

 

Product range offers 12 models with air flow from 150 to 4400 m3/h

 

Heat recovery units could be designed as monoblock or split units allowing easy transport and installation.
According to the room specification, they could be produced for horizontal or vertical installation.


 

 

 

Application
 

 

Personal homes and appartments
Offices
Trade centers
Hotels and restaurants
Small industrial workshops
 

 

 

Annual division of energy costs
 

 

 

 

 

Why high efficiency heat recovery?
 

 

Heat recovery in ventilation systems is an exceptionally profitable investment. It becames more clear from the comparison between system with crossflow and high efficiency counterflow heat exchanger. The payback period is between 1 and 3 years, depending on the running time of the system.
