Description

The Avenger Series boiler is constructed using 100% stainless steel.  The superior two-pass firetube design reduces the cost of manufacturing, maintains performance, quality standards and maximizes efficiency.

The first pass of the heat exchanger consists of stainless steel rifled tubes.  The spiral design increases the turbulence within the tube, which optimizes the velocity of the combustion gases, increasing the heat transfer and efficiency of the boiler.

The second pass features a stainless steel oblong tube, which has a larger diameter compared to the rifle tubing.  The oval design allows us to extract the latent heat from the flue gases, creating condensate in the process.

The Avenger series utilizes a 100% stainless steel burner with a dual gas train, which due to its design, is able to maintain efficiency and low NOx.  The burner is designed to combust a precise amount of premixed combustion air and gas to provide equal distribution of heat throughout the entire heat exchanger.

The Avenger Series is a two-pass counter flow fire tube commercial boiler for hydronic heating applications. It features thermal efficiencies of up to 98% and turndown ratios of up to 40:1
