High-performance heating for large facilities

The TK-24 Professional (70 kW, 4 bar) targets hospitals, university campuses, logistics hubs and office complexes where uptime is critical.

Maximum pressure and test values

This 4-bar model is pressure-tested to 4.5 bar. Powder-coated steel housing and reinforced flanges provide excellent corrosion resistance and rigidity.

Advanced control and modular output

Set 10–90 °C in 1 °C steps via LCD. 70 kW delivered in 10 kW groups with 3-second switching intervals; runtime-based rotation evens out wear.

Smart pump and load management

The pump is externally triggered and runs 2 minutes post-shutdown to remove residual heat; balanced switching improves efficiency and component life.

Safety and uptime

Continuous pressure/temperature monitoring with staged shutdowns; full isolation in critical events.

Audience and use

Professional/industrial use only; not for regular homes. Installed by certified contractors.
