Rinnai TRW Series 2-Unit Sensei CXP Tankless Rack System with Pump, 398,000 BTU

A factory-built wall rack that pairs two Rinnai Sensei CXP tankless water heaters on one frame with manifolds and an integrated pump. Rated at 398,000 BTU and 22 GPM combined, it suits restaurants, hotels and retail sites moving away from storage tanks.

The two CXP heaters arrive mounted on a common frame with factory-tested manifolds, and field connections are a 1-1/4 in. MNPT gas inlet and a 1/2 in. NPT condensate outlet. The heaters divide demand evenly between them for efficiency and a wide turndown range. Water temperature can be set from 98 to 185 F.

CX heaters can be configured for natural gas or propane and installed indoors or outdoors using SmartSense and Versa-Vent technology; this rack is configured for natural gas. Thermal efficiency reaches up to 98%, ignition is direct electronic, and the pump is rated at 1/3 HP. Systems can grow to as many as 24 units for up to 4.8 million BTU, and a BMS Gateway accessory is available for building management integration.
