The Vitoplex 100-LS is a compact three-pass boiler for generating low pressure steam in the output range from 0.26 to 2.2 t/h. The boiler is designed for operation with 1 bar pressure. Subject to requirements, the operating pressure can be reduced to 0.5 bar. Wide water galleries and wide spaces between hot gas pipes and inserts into the boiler wall provide excellent natural circulation and a reliable heat transfer, resulting in high operational reliability and a long service life.

The low material loading through the completely water-cooled rear reversing chamber and the absence of firebrick lining result in an extremely low-stress boiler construction.

A very positive result of the large water content are the favourable operating characteristics during load fluctuations. Residual moisture in the steam is avoided, even when steam is suddenly drawn off or in large volumes, thanks to the boiler design. Consequently, high quality steam is constantly available. The large steam chamber with its correspondingly large evaporator and the integral steam drier support the balanced characteristics of this boiler.

The output range of the Vitoplex 100-LS meets the requirements in air conditioning and heating systems, commercial nurseries and commercial enterprises such as laundries, where low steam pressure is required. The design of this boiler too has been proven in thousands of applications.

The very low combustion chamber volume loading and the three-pass design enable this boiler to stay even within restrictive emission limits.

Three-pass boiler for generating low pressure steam

The Vitomax 200-LS (type M233) is a low pressure steam boiler with permissible operating pressure up to 1 bar, steam output: 2.9 to 5.0 t/h. In this output range, the Vitomax 200-LS covers the requirements of all applications demanding low pressure steam or heat, e.g. airconditioning and heating systems, commercial nurseries or other commercial applications. The Vitomax 200-LS is a three-pass boiler with low combustion chamber loading (< 1.2 MW/m³). This creates the ideal conditions for clean combustion with low nitrogen oxide emissions.

The Vitomax 200-LS benefits at a glance:

• Three-pass boiler with low combustion chamber loading (< 1.2 MW/m3) – clean combustion with low nitrogen oxide emissions

• Low radiation losses through 100 mm thick composite thermal insulation and fully water-cooled reversing chambers

• Economical fuel consumption – boiler efficiency: 92 %

• Excellent steam quality through large steam chamber, large evaporator and integral steam drier

• High operational reliability through excellent natural circulation and safe heat transfer – supplied as standard with robust shipping and installation protection

• Easy to service through large boiler door and easy accessibility during maintenance work

• Walk-on cover on top of the steam boiler as part of the standard delivery – simplifies installation and maintenance
