Enthalpy Heat Exchanger
Operating principleOutlet air humidity is recovered to inlet air through a special patented membrane, which does not allow outside dirt and bacterias to get into premises.
Patented membraneCompared to cellulosic enthalpy heat exchangers, which have a limited life span, patented enthalpy heat exchanger manufactured from special membrane reaches best results in heat and humidity regeneration, moreover, exchanger is very hygienic and durable.
Enthaply heat exchanger – comfortable microclimate in the premises all over the year: inlet air humidifying in winter, drying up in summer.

Better indoor microclimateEnthalpy, like rotary heat exchanger, ensures highest comfort level in premises: when temperature in premises is 20-22 °C, optimal relative humidity is maintained. As we see in the graph below, counterflow plate heat exchanger removes too much moisture, that is why additional moistening is needed.
Greater benefits
Ventilation + humidity control = simpler systemEnthalpy heat exchanger in winter time recovers not only heat, but also most of the moisture to ensure highest comfort level at premises. In summer time enthalpy heat exchanger does not allow excess moisture to get into premises, this advantage allow to save cold air inside and improve savings for air conditioning.
Small possibility for heat exchanger to get iced upEnthalpy heat exchanger can work without icing up up to -15 °C. Standard counterflow plate heat exchangers start to ice up when temperature is below -4 °C.

Parameters of equipment with different heat exchangers in winter:
* conditions: 500 m³/h; winter: outside temperature -20 °C, RH 90%; summer: outside temperature 30 °C, RH 50%; inside temperature 20 °C, RH 40%.
