Blauberg Ventilation has introduced Civic, a new range of German-designed wall-mounted ERV units.
“COVID-19 and the 2019–20 bushfires raised major issues with insufficient quality ventilation in school classrooms and offices,” says the company. “Bad air quality, high humidity levels, high CO2 concentration, and low oxygen levels create a long-term unsafe study and work environment for occupants.”
As noted in AIRAH’s COVID-19 Ventilation Optimisation Guidance Document for Primary and Secondary Schools, some public health authorities have recommended 4–6 air changes per hour, and AS 1668 indicates that the required ventilation to be designed into an active HVAC system for classrooms is 12L/second/person.
Blauberg says the Civic meets these guidelines by providing filtered fresh outside air, rather than filtered recycled air, through a heat exchanger to minimise energy loss. H11 HEPA fresh air filters are included to maximise indoor air quality and safety. And according to Blauberg, with a very low noise level of 24–25 3m dB(A), the Civic units provide a pleasant indoor environment.
Manufactured in Europe, and fitted with Blauberg EC motors for low power consumption, the Civic units can be fitted with an optional fresh air preheater for heating cold winter air, and a CO2 sensor.
An integrated automation system allows for wi-fi, wall mounted control, or integration into BMS control systems.
