Rinnai TRW Series 3-Unit Sensei CX Tankless Rack System, 597,000 BTU, NG

A wall-hung rack that groups three Rinnai Sensei CX tankless water heaters on a single frame with factory-tested manifolds. Together they deliver 597,000 BTU and 33 GPM for food service, hospitality and retail buildings replacing standard or high-efficiency tanks.

This rack is configured for indoor natural gas service and measures 49.10 in. tall, 65.00 in. wide and 11.20 in. deep. The three heaters share the load evenly for efficiency and a broad turndown, with outlet temperatures adjustable from 98 to 185 F. Field connections are a 1-1/4 in. MNPT gas line and a 1/2 in. NPT condensate drain.

CX heaters support natural gas or propane and indoor or outdoor setups through SmartSense and Versa-Vent technology. Thermal efficiency runs up to 98%, ignition is direct electronic, and a BMS Gateway accessory can link the system to building controls. Larger installations can scale to 24 units and 4.8 million BTU.
