Viessmann enlarges Vitocrossal range
Viessmann has added three models to its line of Vitocrossal 200 gas-fired condensing boilers, offering higher heat outputs of 400, 500 and 630 kW. A standard two units can be cascaded to deliver a total output of 1260 kW, though it is possible to cascade up to four boilers. These boilers can deliver flow temperatures of up to 95°C for applications such as schools, hospitals and other buildings with large radiator coverage.
Operating pressure has been raised to 6 bar, to they can be used in high-rise buildings up to 60 m above ground level. They can operate with natural gas, E, LL and LPG.
The Inox-Crossal heat exchangers enables these boilers to achieve a gross efficiency of up to 97%. The stainless-steel heating surface allows condensate to run off downwards to create a permanent self-cleaning effect.
The MatriX cylinder burner uses thousands of tiny flames instead of one large flame to distribute heat evenly.
Noise levels are less than 60 dB(A). All Vitocrossal boilers can be conventionally flued or room sealed.
