Horizontal Type %100 Fresh Air A/C Unit with Indirect Evaporative Cooling (IEC) for cooling spaces which need cooling, heating and ventilation with fresh air without humidifying the supply air. Unit casing is air tight, outer surface powder coated double skin, 45 mm Rockwool insulated for lowest heat transfer and sound absorption. To ensure low energy consumption and meet highest EER (Energy Efficiency Ratio) with IEC, units are equipped with highly efficient counterflow heat exchanger and indirect adiabatic cooling system. Indirect Adiabatic Cooling System is fully equipped with highly efficient evaporative cooling module.
Corrosion free counterflow heat exchanger is air tight and be able to prevent humidity transfer. Heat recovery efficiency of the counterflow heat exchanger is more than %75. Unit can cool down fresh air to a temperature lower than return air temperature, without need of mechanical cooling. Optional mechanical cooling is possible when additional cooling is needed. Free cooling mode is available when outside air conditions are convenient. Supply air can be heated by heatpump or optional electric heater. Unit is equipped with 2 stage filter (optional) in supply air side (G4 panel + F7 compact) and single stage filter in return air side (G4 panel). Optional F9 compact filter is also possible when requested. Unit air volume is adjustable with continues speed controlled via 0-10V, IE4 efficiency class EC direct driven fans, without any need of frequency inverter.
Unit is ready for operation with, factory installed, MCC panel and fully equipped with control components, including factory programmed PLC. Unit can be remote monitored and controlled over Backnet MSTP or Mod-Bus RTU communication protocole.
