DEXA HR

The Elta DEXA HR is a decentralised single-room heat recovery unit — a through-wall fan that alternates between supply and extract every 70 seconds, passing the air through a high-efficiency ceramic heat exchanger. Heat captured from the outgoing stale air is returned with the incoming fresh air, so you tackle condensation and mould without throwing heating money out of the wall. It runs extremely quietly, and the front cover removes easily for filter maintenance.

We offer four models: DEXA HR 100 and 100 Plus+ (Ø100mm) and DEXA HR 150 and 150 Plus+ (Ø150mm).

• HR 100: 25/15/10 m³/h (high/med/low), 2.6–1.2W, 29–10 dB(A); telescopic pipe 270–510mm
• HR 150: 60/40/20 m³/h, 3.8–1.4W, 26–10 dB(A); telescopic pipe 300–560mm
• Reversible EC motor with thermal protection; anti-dust filter; free-cooling mode with LED indicator
