What does a heat recovery ventilation (HRV) unit actually do?

An HRV unit transfers the heat from stale exhaust air to the incoming fresh air stream. This means in winter, instead of losing all that warmth when ventilating, you recover 70–80% of the heat energy that would otherwise be wasted.

Why do ventilation ducts need to be cleaned?

Dust and bacteria that accumulate in ducts over time degrade indoor air quality and can trigger allergic reactions. Clogged filters also put unnecessary strain on fan motors, increasing energy consumption.

What should I watch out for in commercial kitchen ventilation?

Fans must be rated for hot, grease-laden exhaust air, and easily cleanable grease filters are essential. Equally important is a fresh air supply to balance the negative pressure created by the extraction system.

Are ventilation systems noisy?

When engineered correctly and fitted with appropriate silencers and insulation, noise levels stay comfortably within comfort limits. Variable frequency drives (VFDs) allow further fine-tuning of sound levels.

How often does the system need maintenance?

Depending on usage intensity, filters should be checked every 3–6 months. Fan motors and belt-pulley mechanisms are recommended for annual preventive maintenance.
