AB Side Arm Heat Exchanger 38" Double Wall Fin Heat Exchanger Fin-Enhanced Stainless Steel 304 3/4"FNPT Water Heater and 3/4" FNPT Cold Water 18,500 Btu/hr
Efficient Heating: Our side arm heat exchanger is composed of highly conductive stainless steel, 38" in length and can dissipate up to 18,000 Btu's of heat per hour, capable of heating up to a 40Gal tank.
Optimised and Upgraded: Our side-wall heat exchanger uses finned tubes inside to expand the heat exchange area inside the heat exchanger (5-8 times more than bare tubes), with high efficiency and low loss to maximize the heat exchange efficiency.The double wall design provides a the most effective means of protection from domestic water penetration and ensures cleaner water.
Convenient Installation: The ports are standard FNPT threads, 3/4 "FNPT tube (Tank side/Cold water) and 3/4 "FNPT Shell (Water heater side/Hot water), the threads are deep and clear, and the installation is faster.
Thermo-siphon Circulation:Compared to conventional ones, our side arm heat exchangers are designed to circulate using the natural thermo-siphon principle on the domestic hot water side, which saves on pumps and associated electricity costs; on this basis it only takes 3.8 houres to heat a 40Gal tank.
Wide application:Our heat exchangers have a small, space-saving design and slim shape . Widely used in hot water tanks, domestic hot water heating, outdoor wood furnace, solar hot water heating and residential plumbing.
