PURECLASS Series - Decentralized Heat Recovery Units

PURECLASS Series is a “Decentralized” heat recovery units (HRV) with high-efficiency air to air heat exchanger (up to 92% efficiency certified by Eurovent). The fans are designed to elevate indoor air quality while maximizing energy efficiency. Offering flexibility for a classroom or smaller spaces, making them the ideal choice for retrofitting or where space constraints exist with easy installation and no need for extensive ductwork. Ensuring proper ventilation by supplying filtered fresh outdoor air and extracting polluted indoor air, while minimizing air conditioner energy consumption.

Specifications Operating range Nominal airflow of 800 m³/h (with clean filter) and maximum boost mode of 1000 m³/h. Application Air renewal in commercial premises, offices, hotels, public buildings, schools. offering flexibility installation, ideal choice for retrofitting with easy installation and no need for extensive ductwork. High efficiency Fans With EC motor including integrated electronic protection. Integrated dampers (Aluminum slats with actuator in supply air side and backdraft damper in exhaust side). Filtration - ISO ePM2.5 98.5% filters (F7 + F9) are used on the supply air side. - ISO ePM10 50% filter (M5) is used on the extract air side. Bypass 100% fresh air bypass integrated with manual and automatic control. The bypass is particularly useful when the indoors temperature is higher than outdoors and free cooling is preferable. Control Integrated ADVANCED controller. Main characteristics: - Airflow manual and automatic adjustment. - Constant Air Volume without the need to add any accessories. - Variable Air Volume based on an external 0-10V signal from an external CO2 sensor accessory (PURECLASS CO2 versions incorporate the sensor inside) - Bypass automatic control for free cooling and heat exchanger frost protection. - Alarms indication. - Modbus communication. Other data Single-phase electrical supply 230V 50Hz Accessories Remote controller – ETD 5” Touch display. (Not included and have to be order separately). One remote controller can manage up to 5 PURECLASS units.
