WITH HEAT PUMP TANGRA AHU-DEX

Herewith cortlflos thai (n conformity with (oltowlng The microclimate in buildings is one of the most important factors for comfort of the occupants. In the premises with high level of humidity like indoor swimming pools and SPA centers the maintaining of proper temperature and precise humidity is highly significant. An advantage of the air conditioning and ventilation systems is that they not only provide comfort and fresh air, but also prevent condensation on the inner surfaces and thereby preserve buildings structure and furnishing for long time. Traditionally air conditioning and...

The basic construction of the unit consists of special aluminium profiles and aluminium comers. The panels are of the "sandwich"type, consisting of an outer and inner cover with an integrated inner thermal and sound insulation. The covers are made of galvanized sheet steel with powder coating. The thickness of the panels is 25 and 50 mm. TANGRA AHU DEX meet DIN EN 1886 requirements for class T3 MULTIPLE LEAF DAMPER The leaf damper can be operated manually or automatically througn the use of an actuator directly connected to the temperature sensor. This way the water section is safe from...

HEAT PUMP SECTION (Direct expansion section) Heat pump modules in two modifications with indoor and outdoor units incorporated (DEX-M), or with indoor unit incorporated and external outdoor unit (DEX-S). The heat pump units allow easy heating and cooling of the incoming air without the need of additional external energy AHU DEX-M series is compact, with whole heat pump unit incorporated in the AHU's body. Refrigeration modules are with one or two Copeland Digital Scroll compressors. Integrated electric thermostatic valve ensures the smooth operation of the system. The second compressor...

Air-conditioning and ventilation installations are rarely used to the maximum of their capacity. Optimization of energy costs can be achieved by changing the volume of treated air according to the needs of buildings each moment. This can be realized through the use of frequency inverter and programmable controllers. Frequency Inverter Frequency inverter enables smooth speed control of rpm of three-phase motors. This gives the possibility to reduce operating costs by 25%. Protection class of the frequency inverter can be IP20 or IP66, and the control power of motors varies between 0.37 and...
