Technical Highlights

The MIA BGL Cylindrical ERV installs through a single 150mm bore — no ductwork, no demolition, no suspended ceiling required.

Single Core-drill Installation
Single Core-drill Installation
Only one 150mm diameter hole through the external wall — compatible with concrete, brick, insulated cavity walls up to 400mm thick. No ductwork, no ceiling work required. Full installation typically completed within 2 hours per unit.
Rotating Regenerative Heat Exchange
Rotating Regenerative Heat Exchange
Ceramic/polymer rotating core alternates between supply and exhaust cycles every 60–90 seconds, capturing and releasing heat. 70–75% sensible heat recovery without cross-contamination. No cross-flow mixing — air streams are separated by timing cycles.
Paired Installation for Continuous Flow
Paired Installation for Continuous Flow
Install units in pairs — while one supplies, the other exhausts. Synchronized controller coordinates switching cycles for uninterrupted airflow. Each pair covers rooms up to 40 m². Pairs share one controller and power circuit.
