Mechanical Ventilation with Heat Recovery

Clean Fresh Air - while saving you money

The Envirosave range of high efficiency Heat Recovery products includes a small range that extends from 150m3/hr to 550m3/hr over 2 products sizes.

They include high efficiency heat exchangers and EC backward curved centrifugal fans. This smaller range has been designed for use in small commercial or residential applications. They can be used in conjunction with other heating or air conditioning systems to provide fresh air and heat recovery. There are 2 sizes in this range – the HR200, which covers the range 150-250 m/hr and the HR500, which covers the range 300 – 550m/hr.

Features include:

• Sheet-metal construction with Class 0 lining material – note that no flammable components;

• Removable, cleanable exchanger;

• Integrated controls that maximize efficiency and minimize temperature difference to leaving air;

• Remote options for extract boost and on/off;

• Assumption of Fire if leaving temperature exceeds a pre-set temperature or if the fire alarm contacts are closed – this shuts down the supply fan and forces extract fan to full speed;

• System efficiencies are maximized using fully variable Fan speeds, which can be set from 0-100%;

• Dry efficiencies of over 80% can be readily achieved, as can wet efficiencies of over 90%;

• Simple installation and commissioning using standard self sealing spigots and fully variable speed fans;

• Filter access without removing the cover or having to shut down the system.
