Gas fired condensing systems Weishaupt Thermo Condens GB The WTC-GB: convincing quality and power The WTC-GB is available in ratings from 120 to 300 kW, and up to four boilers can be combined into a cascade with a maximum rating of 1200 kW. This innovative development combines intelligent construction, high quality materials and diligent workmanship in a highly relaible gas fired condensing boiler. * Economical heating: The excellent heat conductivity of the aluminium heat exchanger offers the best conditions for economical heating. * Sustained use of gas: The homogeneously prepared air/gas mixture is combusted on the cylindrical surface of the radiant premix burner. The burner's highly resilient metal grill is typical Weishaupt quality. * System monitoring: An electronic monitoring system uses flue gas, flow, and return sensors as well as a water level switch to check the economy of the WTC-GB. * Interface options: The standard eBUS, 0 to 10 Volt, and 4 to 20 mA interface options enable connection with building management systems. * Quiet operation: Operational noise levels are effectively reduced by the sound attenuated air inlet. * More reliability: Electromagnetic interference is avoided by the separation of 230 Volt and low voltage lines. Separate syphons for the heat exchanger and the flue gas system ensure a good draw off of condensates. * Choice of controller: The WTC-GB can be further equipped with the WCM-FS control unit. The WCM-FS provides a clear, menu driven, backlit four line text display.
