Air Design ERU EC Series Energy Recovery Units – ERU420EC-ERV

Air Design ERU EC Series Energy Recovery Units

Performance Curve - ERU420EC-ERV

Description

The Air Design ERU EC Series is a range of compact, horizontal Energy Recovery Ventilation Units designed to fit seamlessly into false ceiling voids between 330mm and 685mm in height. Equipped with a high-efficiency cross-flow heat exchanger, the system recovers thermal energy that would otherwise be lost through exhaust air and transfers it to the incoming fresh filtered supply air. More suitable for warmer or humid climates, the enthalpy heat exchanger transfers both heat and moisture between the supply and exhaust air streams. By pre-conditioning the incoming fresh air, indoor air quality is improved, energy costs could be reduced and a more balanced indoor humidity level is maintain.
