A fan heater is an electrical device used to heat a given space or ensure thermal comfort in a building. There are many different types of fan heater units designed for heating industrial buildings (production halls, warehouses, depots) or commercial buildings (hospitals, hotels, entrance halls, etc.).
What types of fan heaters do we supply?
The category of fan heaters includes heating units with various heat sources designed primarily for industrial buildings. Depending on the heat source available, we can choose between hot water, hot air, steam, electric, or gas hot air heating units. However, we can also offer heating unit solutions for potentially explosive atmospheres - ATEX EX II 2G IIB T4/T3.

What types of water exchangers can I choose from?
Cu/Cu exchanger - heating water - PWW or cooling water PKW
High-performance exchanger for heating with heating water or cooling with cooling water in medium and high air pollution. Improved heat transfer from the pipe to the fins is achieved even with a larger fin spacing thanks to the optimal use of the exchanger surface. The exchanger is made of copper pipes with profiled copper fins, fin spacing 3.0 mm with 1, 2, 3 or 4 rows of pipes. The Cu/Cu exchanger is suitable for connecting the medium from the right or left.
Designation: MultiMaxx HN##.##C###.###
- Maximum operating temperature: 130 °C
- Maximum operating pressure: 1.6 MPa (16 bar)
Cu/Al exchanger - heating water - PWW or cooling water PKW
Standard exchanger for heating with heating water or cooling with cooling water in low air pollution conditions. The exchanger is made of copper pipes with profiled aluminum fins, fin spacing 2.5 mm, with 1, 2, 3, or 4 rows of pipes. The Cu/Al exchanger is suitable for connecting the medium from the right or left.
- Maximum operating temperature: 130 °C
- Maximum operating pressure: 1.6 MPa (16 bar)
Designation:
MultiMaxx HN##.##A###.###
Fe/Fe Zn exchanger - heating water - PHW
High-performance industrial exchanger for hot water heating, suitable for environments with maximum air pollution. The exchanger has a robust design, consisting of elliptical steel finned tubes (S, T) or round tubes (R). The entire exchanger is hot-dip galvanized, which ensures high-quality heat transfer between the tube and fins as well as high-quality corrosion protection. Steel exchangers are designed for PHW heating water and have media connections from the top, right, or left.

Fe/Fe heat exchanger - steam
High-performance heat exchanger for steam heating in environments with maximum air pollution. The exchanger has a robust construction made of steel circular finned tubes. The entire exchanger is hot-dip galvanized, which ensures high-quality heat transfer between the pipe and fins as well as high-quality corrosion protection. Steel exchangers designed for steam are suitable for connecting the medium from above (condensate drainage is provided at the bottom).

Cooling with condensate drain or condensate pump
The MultiMaxx HN units can be used in cooling mode in addition to heating. The Cu/Al or Cu/Cu exchanger can be operated with cooling water or a mixture of water and glycol. Units equipped with a 3-row or 4-row exchanger and a lower speed motor fan are used for cooling. Thanks to the lower air speed, condensate is reliably drained into the condensation tray.
