Frequently asked questions
What is a heat-recovery AHU?
A supply-and-exhaust air-handling unit (AHU) delivers fresh air and removes stale air at the same time, while the heat exchanger transfers heat from the exhaust to the supply flow. This retains up to 90% of the heat and cuts heating costs.
What is the capacity of EZERVENT units?
The residential and commercial series (CPH, FRH, FRV, FPH, FPV) range from 250 to 3000 m³/h. The industrial EZ BLD series spans 500 to 9000 m³/h, made to order.
What is the heat-recovery efficiency?
Plate heat exchangers reach up to 85% efficiency (around 81% in EZERVENT models), rotary up to 90%, and glycol up to 80%.
How do rotary and plate heat exchangers differ?
A rotary exchanger has higher efficiency and retains humidity, but the airflows partially contact. A plate exchanger fully separates supply and exhaust without mixing the air.
Can a unit be built for a specific facility?
Yes. The EZ BLD series is made to order from a questionnaire: heat-exchanger type, heaters, coolers, filters, and controls are selected for the facility’s requirements.
