Heat Recovery Ventilation

As our homes become more airtight forced ventilation is becoming an essential feature of domestic and commercial building design. Currently the most common approach is to exhaust expensive heat energy with contaminated air.

Our System is capable of between 50% and 90% heat recovery at between 900-2000m³/h. Raising the temperature of this volume of air by 10°c, as demonstrated by the system would require an 8kW heater battery.

These figures are the results of empirical data (collected from actual working machines in venues and businesses). and are not derived from laboratory test.

Our domestic heat recovery system is manufactured in 450m³/h and 1000m³/h. These units are built to the same specifications as our industrial systems. With:

• DC or Inverter type technologies
• Patented Heat Recovery Technology
• High efficiency fan technology
• Up to 90% heat recovery
• Silent Operation
• Self-Cleaning Core (No Clogging)
• Easy Filter access
• Speed Controlled
• Built in humidistat

Units can be supplied with different spigot or louvre configurations.

Sigma HRV 450

A one-off investment in our HRV system will lower your energy consumption and deliver savings.

With the increasing cost of domestic energy and the need to reduce greenhouse gas emissions, it is in all our interests to make our homes more energy efficient.

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 the family.

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