Product description

Maintaining   the climat in premises, with minimum energy consumption is major factor in operation cost management of the buildings. Tangra EVB AL/AL+ heat recovery installations provide a flow of fresh air with temperature, close to this in the room, using the heat of the exhuasted air.

 

 

Application / Usage

EVB AL/AL+ energy saving and heat recovery units manufactured by Tangra are designed for installation in

 

Appartments and family houses
Offices
Trade centers
Hotels and restaurants
Factories
Agricultural facilities
 

 

Product range

Product range of 9  models cover air flows from 250 to 8500 m3/h

 
Heat recovery units could be designed as monoblock(04-42) or split units(60-80) allowing easy transport and installation.
According to the room specification, they could be produced for horizontal or vertical installation.

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.
