On the 27th, Rinnai Korea has launched "Cascade (Model No.: RCW-26CFM/CEM)", a commercial water heating system that connects several condensing water heaters to a single exhaust stack and chooses a master water heater to comprehensively control other water heaters.

Rinnai Cascade system was developed to replace mid- to large-sized boilers in various commercial facilities including buildings, hospitals, hotels and saunas. It contains a leading-edge ratio control feature that automatically controls the number of machines in operation based on the amount of capacity used, boasting a superior gas cost reduction effect compared to existing mid- to large-sized commercial water heaters.

Also, when a failure occurs and waits to be completely repaired, existing mid- to large-sized commercial water heaters inflict damage on the water heating system of the entire establishment while, if a water heater breaks down, Rinnai Cascade system enables other water heaters connected in parallel to the broken one to operate as a substitute, preventing potential damages and enhancing customer satisfaction.

It especially possesses a leading-edge ratio control feature, which controls the number of machines in operation based on the amount of capacity being used, boasting a superior gas cost reduction effect compared to existing mid- to large-sized commercial water heaters.

Moreover, the use of freeze-protection heater and combustion function completely block out any potential danger of implosion due to freezing of the heat exchanger within a water heater, and the system is also equipped with various safety systems such as overheating-protection device and safety device that prevents backflow of exhaust gas.

 Along with Cascade, an all-new eco-friendly condensing gas water heater (Model No.: RCW-20CF/CE, 26CF/CE) with Grade A in energy efficiency ratio has been launched.

As the idea of efficient energy use has been trending in the national scale and energy reduction in apartment buildings and commercial facilities has become a great movement of this era, Rinnai finally launched a new product based on the experiences and know-how in developing the first parallel system in the country in 2000.
