Three Pass Gas & Oil Fired Central Heating Boilers
Three pass design provides optimum thermal balance, effective heat transfer and low operating costs.
Lower heat load by means of large water volume.
Optimum furnace geometry.
Longer boiler life due to continuous draft of three passes and balanced cooling of flue gas.
Minimum pollution to environment by means of low flue gas emissions.
Radiation heat losses and stand by losses are minimized by means of 100 mm glass wool insulation.
Robust boiler design with large water volume, large wet back surface and optimum furnace.
Optimum heat transfer by 3-pass and wet-back design
Very low radiation losses by means of good insulation of compact, cylinderical shell.
High operation security by means of integrated injector plates designed for homogenous temperature distribution re-directing return water to hot areas of the boiler.
Better emissions due to low furnace heat load.
As occasion may require, it enables to use of solid fuel with inventory grating.
