Vitocrossal 300 CT3U 400 kW RLA, GC1B

Advanced condensing technology makes the Vitocrossal a frugal condensing boiler that is suitable for many di erent applications. The Vitocrossal range, from 87 to 1400 kW, o ers a perfect solution for every application – from heating apartment buildings and public or commercial premises, through to generating heat in local heating networks. Advanced condensing technology The stainless steel Inox-Crossal heat exchanger provides ideal conditions for utilising condensing technology. The smooth stainless steel heat exchanger allows the condensate created by the condensing process to simply runo downwards. Combined with the smooth stainless steel surface, this creates a permanent self-cleaning e ect, thus ensuring that the condensing technology is utilisedat a permanently high level, resulting in a longer service life whilst also reducing the maintenance e ort. The Vitocrossal 300 is available with a factory- fitted MatriX radiant burner or prepared for fitting ELCO or Weishaupt pressure-jet gas burners. The highly e ective heat transfer and the high condensation rate enable standard seasonal e ciencies [to DIN] up to 98 % (Hs) [gross cv] / 109 % (Hi) [net cv] to be achieved. These high levels of standard seasonal e ciency are the result of the countercurrent principle of hot gases and boiler water, along with intensive turbulation of the hot gases as they pass over the heating surface.
