SYSTEM COMPONENTS

3.1

• The Air Change Wall Mounted Energy Recovery Ventilator (WM-ERV) has been

developed for Classrooms and other applications to supply fresh air to meet

Ventilation codes. The system pre-cools or pre-heats and dehumidifies outdoor

air by transferring the energy from the return air through the heat exchanger

walls to the incoming outdoor air. The Enthalpy Heat Exchanger inbuilt in the

Ventilator has been designed to return around 75% efficiency.

• The WM-ERV is professionally assembled, internally wired through out, with easy

access for filter change. The Front grille is designed to be removed by lifting

upwards and then pulling towards you, allowing access to filters. Remember to

always turn the power off before removing the front grille.

• The WM-ERV provides 300 l/s outdoor air on low speed and 350 l/s outdoor air

on high speed.

System Components

• Prefabricated wall and ceiling panels of are constructed of 1.2mm galvanised

sheet metal, bonded to 10mm aluminium polyethylene insulation.

• Supply and exhaust fans are 80W centrifugal direct drive and are constructed

using forward curved vanes fabricated from galvanised steel.

• Fans are controlled by an HPM electronic speed control.

• The Energy Reclaim (enthalpy) heat exchanger uses a combination of cross

flow and counter flow, with enthalpy transfer media between moulded plastic

air guiding frames for a very high efficiency and long life. The heat exchanger

has been secured under pressure by galvanised steel end plates and corner

fittings.

• There is no cross contamination between the air paths.

• The counter flow enthalpy heat exchanger incorporated into the unit will

reclaim up to 75% of the energy (under normal operating conditions) from the

return air and transfer it to the incoming outside air, i.e. to pre-treat the

outside air. This results in a saving of up to 75% on the cost of heating or

cooling the outdoor air. (Typical ERV use with normal air conditioning, see

Plan and Side View schematic).
