Heat Recovery Ventilation

Heat Recovery Ventilation


A one-off investment in a Sigma HRV system can dramatically reduce your energy bills and clean your environment leaving you with better indoor air quality.

The Sigma HRV supplies 100% fresh filtered air and removes contaminated air while reducing heat loss.

Our patented technology is built on the counter flow principle, which is the most effective method of heat recovery. It creates a clean and comfortable environment for customers and staff alike (See diagram).

Sigma HRV dramatically cuts the cost of ventilating your premises. Our heat recovery ventilators can be used in hospitality venues, homes, factories, offices… in fact in any environment where cost effective ventilation or heat recovery is required.
