High-capacity solution for large buildings
The TK-24 Professional (80 kW, 4 bar) is tailored for hospitals, campuses, logistics hubs and office complexes with consistently high heating demand.
Maximum working pressure and testing
Rated for 4 bar working pressure, pressure-tested to 4.5 bar. Powder-coated steel housing and reinforced flanges ensure mechanical strength and corrosion resistance.
Modular output and smart control
LCD microprocessor control, 10–90 °C range (1 °C steps). 10 kW modules, activated in 3-second intervals. Runtime-based sequencing balances group wear.
RS and Modbus connectivity
Built-in RS and Modbus support allows seamless integration into Building Management Systems (BMS). Operators gain remote control and monitoring options.
Pump and load management
Pump auto-starts on external signals, runs 2 minutes post-shutdown. Load balanced across groups for optimal efficiency.
Safety and uptime
Pressure and temperature monitoring ensures reliability. Elements shut down in case of anomalies; full isolation in critical events.
