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.
