Vitomax LW

The energy efficient and clean provision of heat, along with high operational reliability and plant availability, are essential requirements for heating centres in large buildings and industrial plants. Vitomax LW are low pressure hot water boilers for flow temperatures ≤ 110 °C and a permissible operating pressure of 6, 10 or 16 bar.

The three-pass boiler features low combustion chamber loading with clean combustion and low nitrogen oxide emissions. In gas operation, the low NO_x series have NO_x emissions of less than 70 mg/Nm³; in oil operation they are less than 150 mg/Nm³.

A low stress, space saving design ensures good natural circulation and reliable heat transfer. As with the Vitomax HW, additional boiler pumps are not required, which significantly simplifies the hydraulic connection. The optimum heating surface and smoke tube design ensures low pressure drop on the hot gas side.

All Vitomax LW low pressure hot water boilers are suitable for the combustion of up to 100 % hydrogen when complying with our framework conditions for the use of H₂.

New heating centres for industrial and commercial enterprises often have to be ready for operation within a short time in order to be able to supply heat on schedule. This is particularly true in the case of restructuring or modernisation, when a system is replaced during ongoing operation. In this case, the system operator can rely on Viessmann's proven and reliable technology.

In an industrial/commercial boiler plant, the Vitomax LW low pressure hot water boiler offers a high level of planning and calculation reliability. As well as guaranteeing highest quality and flexibility, all components are reliably matched. For example, through pre-assembled safety equipment for maximum temperatures of 110 °C. Accessories include flue gas/water heat exchangers for use in non-condensing and condensing technology, which improve the efficiency of the boiler to over 95.5 percent. Return temperature raising, pressure maintenance and flue components are also available.

In continuous operation, Vitomax hot water boilers score highly because they are easy to service, thanks to the wear-resistant and water-cooled burner entry point and rear reversing chamber without refractory linings, available on request. This dispenses with the need for a refractory lining drying process, significantly reducing commissioning and servicing times. The load bearing boiler cover simplifies installation and maintenance, and protects the thermal insulation against damage.
