ZEUS
MODRATHERM ZEUS boilers are produced in the following capacities:
-
MODRATHERM ZEUS 25/20 – 3 Hot water steel boiler for burning solid fuels, mainly biomass such as lump wood, wood briquettes with a thermal output of up to 22 kW and a maximum operating pressure of 0.25 MPa.
-
MODRATHERM ZEUS 25 – 3 Hot water steel boiler for burning solid fuels, mainly biomass such as lump wood, wood briquettes with a thermal output of up to 27 kW and a maximum operating pressure of 0.25 MPa.
-
MODRATHERM ZEUS 30 – 3 Hot water steel boiler for burning solid fuels, mainly biomass such as lump wood, wood briquettes with a thermal output of up to 32 kW and a maximum operating pressure of 0.25 MPa.
-
MODRATHERM ZEUS 35 - 3 Hot water steel boiler for burning solid fuels, mainly biomass such as lump wood, wood briquettes with a thermal output of up to 37 kW and a maximum operating pressure of 0.25 MPa.
-
MODRATHERM ZEUS 40 - 3 Hot water steel boiler for burning solid fuels, mainly biomass such as lump wood, wood briquettes with a thermal output of up to 42 kW and a maximum operating pressure of 0.25 MPa.
The boilers are designed primarily for burning wood with a water content of up to 20% with a maximum length of up to 550 mm. The boiler body is made of high-quality heat-resistant boiler steel with a thickness of 5 mm (the walls of the combustion chamber that are in contact with the flame and water) and a thickness of 3 mm (the walls that are in contact with water only). The insulating cover is made of 1 mm thick steel sheet and surface-treated with static powder coating technology. The thermal insulation is made of mineral wool. The grate is cast iron, sectional. Depending on the design, fireclay fittings are also located in the lower part of the flue gas space. On request, the boiler can be supplied with a grate surface with a monolithic grate and LacFire 1550/30 refractory concrete fittings. More information can be found in the grate surface section.
The modern design of the heat exchange surfaces and combustion chamber guarantees perfect combustion with high efficiency and low formation of harmful substances in the flue gases.
The boiler can be connected to the heating system with threaded connections G 6/4". The connection pipes of the safety exchanger are made with threads G 1/2".
MODRATHERM ZEUS boilers are produced in the following versions:
-
Version 1 For open systems without a circulation pump. In combination with DBV2 also for systems with a pump.
-
Version 2 With an integrated safety copper exchanger that ensures the boiler's protection function against overheating
-
Version 3 With an integrated copper DHW exchanger, or with a safety copper exchanger, which ensures the boiler's protective function against overheating
Advantages of MODRATHERM ZEUS boilers
