Stand alone reversible air-to-air Rooftop unit, for the thermo-hygrometric treatment, filtration and air renovation, in medium-large surface and volume environments (supermarkets, shopping or exhibition centres). VSD scroll compressors for sizes < 120 kW and 4 ON/OFF tandem compressors for higher capacities. Together with electronic lamination valves, these solutions allow to punctually follow the building demand, getting the highest efficiencies with relevant energy and cost savings. According to the selected version, the unit can manage the free cooling operation thanks to motorized dampers for return, exhaust and fresh air. The unit is also available with the thermodynamic and Refrigerant Booster heat recoveries, air-to air Plate type or rotary heat exchangers, to recover the energy from the exhaust air, increasing the unit capacity and the global efficiency.
The pure refrigerant R32 is an extraordinary eco-sustainable alternative to traditional refrigerant R410A, offering a 66% reduction in terms of GWP, a higher efficiency and a lower refrigerant charge.
Top-level partial load efficiency, granting an effective energy and economic savings, thanks to VSD scroll compressors for sizes < 120 kW and 4 ON/OFF tandem compressors for higher capacities.
The wide working range, the inverter technologies and the tandem compressors, together with the accurate design of the components, ensure optimum performance and comfort, with a continuous and constant operation also during heavy thermoigrometric conditions.
The unit is available with the opportunity to choose different supply and return airflow directions and is always delivered as packaged unit with all the desired configurations.
The exclusive enthalpic rotary heat recovery recovers both sensible and latent heat from the exhaust air, in winter and summer operation. The recovery of the latent heat improves the dehumidification capability of the unit in summer and the humidification in winter, with a very high efficiency ratio.
The static plate heat recovery provides a constant and effective recovery of the sensible energy from the exhaust air, keeping always the supply and the return airflows separated. In winter mode the efficiency can reach high values, that, together with the zero energy consumption of the component, grant an effective energy and economic saving.
Cutting-edge Refrigerant booster heat recovery system that completely and precisely recovers of the energy from the exhaust air, without any waste due to the mixing with external air. The performance of the cooling circuit is maximized, increasing the cooling capacity by 15% and the compressor working at the same condition.
Thanks to the advanced logics of AIR3000+, the Variable Airflow Function allows to adjust the supply and the return airflows according to the real plant demand, granting an important reduction (up to 30%) of annual energy consumption.
Ensuring continuous and efficient unit operation in any condition or situation is a fundamental preliminary requirement to guarantee a wide range application framework. The rooftop unit is able to independently manage additional air treatment resources, and take advantage of any favourable weather conditions. Moreover, it must also deal with critical operating conditions that could reduce the capacity delivered.
WSM3-G07 is an autonomous rooftop unit dedicated to air handling and air renewal in comfort applications and public spaces.
Thanks to different layouts and a cooling range from 80 to 320 kW, the new range meets the requirements of both medium volume spaces and big buildings.
