alt The heat exchanger is a two-pass drum and tube type with the choice of 409 HP, 304L or 316L stainless steel. Efficiency is at least 80% and can be as high as 87% at low fire.
The new high turndown burner design offers turndowns up to 30:1 and features a cast aluminum fan and burner head with stainless steel baffles for corrosion-free operation.

Firing rate is controlled by a PLC that drives and analyzes valve position, fan speed, and pressure from low to high fire, ensuring clean and efficient combustion.
