Arne flue gas economiser

Flue gas economiser for use with non condensing power flame boilers.
Available in 18 models to be used with both individual and multiple boiler applications.

Product information

Saves money and increases boiler efficiency by re-using heat from the boiler flue gases.
Versatile design gives the Arne the ability to be used in both new and existing commercial boiler installations.
Manufactured with high quality stainless steel tubes, providing less resistance and higher tolerance of flue gas condensate.
There are 14 models available in the standard Arne Eco range suitable for boiler outputs from 130kW to 5630kW.
There are 4 models of the Arne Eco Turbo available. These economisers are designed for multiple boiler installations with outputs from 400kW to 1430kW.
Choice of flue connection to the side or rear of the economiser.
Especially suited for installation with floor standing sectional or steel shell power flame boilers such as Hamworthy’s Ensbury LT and Melbury HE.

Recover heat from flue gases of a non-condensing boiler to increase efficiency by up to 18%.
