The Hunt HEFec range of Flex watertube boilers has been created to minimise overall space requirements, while still focusing on optimal energy efficiency with the incorporation of the most up-to-date technology available.
The design includes special stainless steel baffles that promote four pass hot gas circulation in the boiler, together with an integrated Flue Based Economiser (FBE), that work to ensure excellent heat transfer rates and the best possible recovery of any remaining latent heat.
They are manufactured in our Hunt Boilers' Victorian workshops and our International facilities, configured for Unattended operation and are available in standard form from 850 kW to 2000 kW.
The HEFec range is provided with standard design pressure of 1200 kPa, and is suitable for a wide range of fuels including Natural Gas, LPG, CSG, Bio Gas, Oil and various dual fuel options.
The key features of the product range include:
- Conservative heat transfer rates with over sized heating services
- Smaller footprint than traditional water tube boilers, without compromising efficiency
- Incorporating four pass hot gas circulation and additional two pass with the integrated FBE technology for very low energy costs
- Large steam and water drums to increase accumulation to better meet fluctuating demands
- Inspection openings fitted to water and steam drums to enable effective inspection
- Side panels are removable providing excellent access to combustion spaces
- Fully packaged complete with feed water pumps
- Water level controls fitted directly into boiler drum
- High class finish and appearance
- Higher pressure models also available
