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.
Self supporting construction of galvanized steel, powder coated from outside. Internal acoustic and thermal insulation. Appropriate for indoor insulation, entirely visible or particularly incorporated in suspended ceiling.
Monoblock construction for horizontal installation in false ceiling. Internal acoustic and thermal insulation; 25mm panels are on request. Suitable for whole-house ventilation installation.
Self supporting construction with double panels of 25mm with acoustic and thermal insulation, made of galvanized steel and powder coated. Designed for vertical installation in basement, or technical rooms. Suitable for whole-house ventilation installation.
Systems for heat recovery with heat pump incorporated module TANGRA EVB DEX are designed for ventilation and air conditioning of houses, offices, commercial buildings, restaurants and disco clubs.

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
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.

Online tool / Software for calculation
You could use our online (web based ) sofware tool for calculation of heat recovery units at Tangra website
Step 1
Select the EVB which suits your needs in terms of air flow and range:

Step 2
Enter your configuration options for the EVB unit
- Standard air volume – supply air, m3/h
- Standard air volume – exhaust air, m3/h
- Temperature of the supply air, oC
- Temperature of the exhaust air, oC
- Atmospheric pressure, mm Hg
- Relative humidity fresh air
- Relative humidity exhaust air
