Updated heating cuts energy bills for engine components factory
A change in heating technology for a factory has helped reduce the building’s energy use by nearly 70%. Heating for the factory of Unison Engine Components at Burnley is now provided by a Nordair Niche variable-air-volume external direct-gas-fired system. It replaces ineffective and costly unit heaters. Winter gas savings are around 70% compared with the original system.
Unison is a world lead in engine components and mechanical and electrical for jet engines. Ashton-based heating specialist Harry Taylor was appointed to design the new heating for the 9600 m2 factory.
The new system comprises two heating and a Trend IQ3 controllers.
The new system provides heating and tempered-air ventilation, precisely matching the existing extract system by linking inverter-driven supply fans to vary airflow by up to 50%. The burner is also modulated according to the temperature of the outside air.
By slightly pressurising the building, the H&V system discharges its air through unobtrusive wall-discharge heads without the need for high-level ductwork runs.
The positive pressure reduces cold draughts, and the system can also provide free cooling in the summer.
Trend IQ3 LAN controllers complete the system and provide frost protection, timed summer ventilation, weather-compensating modulation and many more features.
