HEAT RECOVERY

Heat recovery ventilation I Maintaining the microclimat in premises with minimum energy consumption is a major factor in the management of operation costs in buildings. Heat recovery installations provide a flow of fresh air with temperature, close to this in the room using the The heat recovery units manufactured by TANGRA are - Appartments and family houses - Trade centers - Agricultural facilities Under certain temperature conditions, a device controls the ON/OFF function of the automatic bypass. In this way, the fresh air passes through the filter and is directly supplied to the room...

Heat recovery ventilation Product range Product range of 9 models cover air flows from 250 up to 8500 m3/h. Heat recovery units could be designed as monoblock (04-42) or as spli systems (60-80), allowing easy transport and installation. According to the room specification they could be produced for horizontal or vertical installation. \/N/ System with recuperative plate ' heat exchanger * - Initial investment S1 - System without heat recovery S2 - System with 55% heat recovery Life-time (years) Crossflow heat exchanger REC AL The graphic shows the initianl investment and the accumulation of...

Heat recovery ventilation Horizontal installation Standard model Side panels of the supply and suction side of the unit are interchangable. In this way, it is possible to make different configurations (see p. 15). As standard this units are produced with rectangular connections. We reserve the right to introduce alternations both in design and technical data without prior notice, due to continued product development.

Heat recovery ventilation Horizontal installation Model with bypass Side panels of the supply and suction side of the unit are interchangable. In this way, it is possible to make different configurations (see p. 15). As standard this units are produced with rectangular connections. We reserve the right to introduce alternations both in design and technical data without prior notice, due to continued product development.

In this way, it is possible to make different configurations (see p.15). As standard this units are produced with rectangular connections. We reserve the right to introduce alternations both in design and technical data without prior notice, due to continued product development.

Heat recovery ventilation Technical data VR - Speed controllable motor by tension Recuperativ heat exchanger AL Recuperativ heat exchanger AL+ Note: Efficiency data are valid at equal mass flows of both flows and at 22°C and 25% relative humidity of the exhaust air. If the relative humidity rised, the efficiency will increase with 3+5%. We reserve the right to introduce alternations both in design and technical data without prior notice, due to continued product development.

Heat recovery ventilation These values are measured at the fan exit at maximum speed. Heat recovery units offer the following options for control: TANGRA ETY/STL/MTV Only fan speed control (two controls per unit) Bypass valve operates automatically, according to signals The pre-heater turns on automatically on signal for freezing. - Air quality sensor with integrated timer. The unit allows to set a level of pollution of the environment, when the fan turns on and duration of the operation period. - Bypass valve operates autimatically, according to signals - The pre-heater turns on...

Heat recovery ventilation The calculation of fresh air volume is based on the room area, number of people and room categorie. floor area The lowest requirements of fresh air per 1sq.m. are in open space office areas and the highest are in high halls, kindergarden and Sound attenuator - with rectangular or round shape. Reduce the noise level, transfered by the duct system. Air filter F7 - As a standard, the unit is produces with filter G4 EN 779:2002 for fresh and exhausted air. As an option it is possible to produce the unit with filter class F7, which leads to reduction of the external...
