Rinnai TRS SENSEI CX 4-Unit Free-Standing Tankless Rack System, 796,000 BTU

This Rinnai TRS Series rack banks four SENSEI CX tankless water heaters on a free-standing frame, rated for 796,000 BTU and 44 GPM in total. With several heaters sharing the work, one unit can be offline without cutting the hot water supply, a good fit for restaurants, hotels and retail sites.

SENSEI CX heaters use SmartSense and Versa-Vent technology for indoor or outdoor installation. The rack arrives fully assembled on its frame with factory-tested manifolds.

This configuration burns natural gas with direct electronic ignition and offers a 98-185°F temperature range. It has a 1-1/4 in. MNPT gas connection and a 1/2 in. NPT condensate connection, measures 57.69 in. high, 47 in. wide and 28.59 in. long, and weighs 562 lb.
