Heat and energy recovery ventilators HRU-ERGO

Heat and energy recovery ventilators supply fresh air heated by the outgoing air to the facilities.Heat and energy recovery ventilator has high efficient counter flow heat
exchanger.

The clearance between the fibers is very small, so only the moisture molecules of small
diameter can go through, the odor molecules of larger diameter are unable to pass through it.

By this means, the temperature and humidity can be recovered smoothly, and prevent
the pollutants infiltrating to the fresh air.

HRU-ERGO	Heat and energy recovery ventilators with enthalpy The HRU-ERGO heat recovery ventilator is a suspended unit with an extremely efficient counter-flow heat exchanger. The heat exchanger is made from plastic and processed cellulose which has a high water vapour permeability ratio, good air tightness, and good resistance to ageing. The spacing between the cellulose fibres allows free passage of water vapour molecules. Larger molecules, like those of odours, cannot pass through the heat exchanger. This prevents the contamination of the fresh air supplied indoors. The heat recovery ventilators are available in an output range from 250 m3/h to 1000 m3/h. A standard HRU-ERGO heat recovery ventilator features 10-speed energy-efficient fans, automatic air bypass, defrosting mode (based on a fan speed control algorithm), 2 air filters, and steel duct connections. Optional accessories include the HDE-CO electric heater and the HDW water heater, the HRU-CONTR-TPAD touch-screen controller, as well as CO2 and air humidity sensors.

HRE-ERGO	Counter-flow heat exchanger for heat recovery ventilators The HRE-ERGO counter-flow heat exchanger is intended for the HRU-ERGO heat recovery ventilators. The heat exchanger is made with a paper material which features a high water vapour permeability, good air tightness, and good resistance to ageing. The spacing between the cellulose fibres in the material allows free passage of water vapour molecules. Larger molecules, like those of odours, cannot pass through the heat exchanger. This prevents the contamination of the fresh air supplied indoors.	Counter-flow heat exchanger for heat recovery ventilators
HDE-CO	Electric duct heater HDE-CO electric duct heaters can be used as optional heaters for the HRU-ERGO energy recovery unit. Depending on the functions of heaters in ventilation system, duct heaters can be divided into: - preliminary - secondary A preliminary heater is installed on the exhaust duct of HRU (fresh air from outside) and it is used to preheat the air supplied to the heat recovery unit. The preliminary heater is fitted to prevent freezing of the heat exchanger at extremely low outside temperatures and it does not affect the temperature in the room. The standard HRU-ERGO unit has an automatic frost protection function, which protects from freezing by periodic altering of fans’ speed. It is recommended to use a heater with one contactor type HDE-CO1 or with two contactors type HDE-C02. A secondary heater is installed on the supply air duct (fresh supply air to the room) and it is used for additional heating of the supply air temperature. After connecting the heater to the HRU-ERGO unit we are able to task the temperature in the room when we feel that thermal recovery alone is not enough for our comfort. We recommend a duct heater HDE-CO2 with two contactors.	Electric duct heater
