These are available in capacity of 0.7mw. To 14mw. Components are engineered for maximum safety, highest efficiency, dependability and quit operation. Wet back models eliminate rear end refractory and its inherent maintenance cost, reduces stress of rear tube sheet and ligament cracking, radiant heat is eliminated, lengthening tube life and reducing heat loss from rear turn around.
Wns gas & oil fired hot water boiler feature:
1. Fully wet - back design effectively absorbs radiant heat into the water, keeping tube ends and rear of coiler cooler than in dry back design.
2. Three passes extract maximum useable heat from the fuel.
3. Large , water - surrounded furnace tube assures complete combustion and heat absorption without flame impingement.
