The multicratboiler is a proven construction for generation of warm water until 110 °C with 4 bar operating pressure. The boiler output is 650 kW until 2,000 kW. The boiler construction is a three-pass-boiler with open fire tube channel and above arranged boiler passes. Cleaning during the boiler operation by means of a compressed air cleaning plant. Below the boiler the different types of furnaces can be installed. Most commonly is this boiler system used with push grate furnace for burning dry and wet fuel as well as with nozzle grate furnace for burning pellets.

The turbocratboiler is a three-pass-fire tube boiler for generation of warm water of 110 °C  and 10 bar, of hot water until 160 °C and 10 bar, of low pressure steam until 1 bar and high pressure steam until 10 bar. Boiler output is 1,000 kW until 8,000 kW. The turbocratboiler as three-pass-boiler is designed with a big fire tube, this is the combustion chamber. This ensures an optimum burn-up rate, because of the flue gases residing time and good mixing. The furnaces are installed below the boiler, whereby the flue gases flow below into the boiler fire tube. It is possible to design the turbocratboiler with a compressed air cleaning plant and a flue gas temperature increasing device for the control of the boiler waste gas temperature. Most commonly is this boiler system used as industry boiler for heat generation in the middle output range. An ideal design of the turbocratboiler is one with nozzle grate furnace for burning pellets.

The three-pass-boiler is a 3-pass fire tube boiler for generation of hot water until 200 °C and high pressure steam until 32 bar. The boiler output is 1,000 kW until 15,000 kW. The three-pass-boiler is for heat generation installed after the furnace. The flue gases flow in the inside of the flue tubes and the water in the boiler pressure vessel flows outside of the tube. For cleaning of the flue tube there is a compressed air cleaning plant installed. All types of furnaces can be used with that boiler.

Air source heat pump in monoblock design - Rated heating output: 2.6 to 14.9 kW, High energy efficiency, Sustainable operation, Cooling function. 

Viessmann oil condensing boilers come prepared for the future. They are supplied ready equipped to accommodate a changeover from fossil oil to fuel oil mixed with a certain percentage of bio-oil, and so can also be used with renewable fuel types.

Energy efficient and clean provision of steam, as well as high operational reliability and plant availability, are essential requirements for production facilities and industrial plants. Each individually tailored system solution will have specific requirements that need to be taken into account when designing the boiler house concept.This requires competent consultation, together with a comprehensive range of services and products that guarantee cost effective, futureproof steam generation.
