Location: Bradford Ventilation Manufacturing Facility Seven Hills, NSW, Australia
Business: Bradford Ventilation (previously Edmonds) is a designer and manufacturer of energy efficient, natural powered and hybrid ventilation products.
Task: As part of the relocation of Bradford Ventilation manufacturing to a new and larger facility, an Ecopower® 900 hybrid ventilator system, with integrated temperature control, was installed to improve comfort for employees.
The units remove excess heat from moulding and powder coat processes ensuring the constant exchange of air in a building with limited external openings.
Solution: The ventilation system was designed to provide up to 4 air changes per hour at maximum demand and comprises of 22 x ecopower 900 hybrid vents. During mechanical operation each ecopower 900 exhausts 10,000m3/hr and about 3,000m3/hr in wind mode only, (based on testing to AS4740).
Powered operation of the vents is activated at 25°C through an ebm-Papst integrated temperature controller. The controller manages the speed of the motor to try and maintain temperature just below the vents at the target level.
