enhanced combustion design that allows for
easier installation and enhanced operational
performance and serviceability. All of the key
components in SENSEI are designed and
manufactured by Rinnai – ensuring maximum
quality and reliability from the industry leader in
commercial tankless water heating solutions.
• You can now vent with 2 in. PVC (NEW) up to 65 ft.*
• You can vent using 2 in. / 4 in. (NEW) or 3 in. / 5 in.
concentric pipe*
• The most Common Venting options oered to
meet commercial needs
• Stainless Steel Primary Heat Exchanger
• Integrated temperature up to 185° F
• Cascade Cable Assembly allows for up to 24
water heaters to be connected and function as
one hot water source
*Single unit only
INTEGRATED
CHECK VALVE
Check valve integrated between the fan
assembly and combustion chamber
• A more powerful combustion fan allows the
longest vent runs in the industry
• No check valve above water heater reduces
cost and size of common vent
• Additional freeze protection
• Prevents backdraft of exhaust with
common vent
PRIMARY STAINLESS STEEL
HEAT EXCHANGER
Made from 400 Series Stainless Steel, which is
superior for corrosion resistance and minimizes
expansion and contraction, the R-evolution
provides superior thermal conductivity.
The tube design is 1mm thick (25% thicker than
competitive products) 444 Stainless Steel and
fluorine gaskets are used at the joints to provide
added durability and heat resistance.
INTEGRATED
CASCADE LOGIC
With the use of cascade cable(s) up to 24 water
heaters can be electronically connected. This
connection will rotate water heater operation
order to ensure equal usage among the entire
system and function as one hot water source.
