Industrial heating for high-pressure networks

The TK-24 Professional (70 kW, 6 bar) serves production halls, process heat loops and complex district sub-nets requiring high availability.

Maximum working pressure and testing

Reinforced design, pressure-tested to 7 bar and rated for 6 bar max. Powder-coated steel chassis and reinforced flanges ensure durability under load.

Control architecture and modular output

LCD interface with 10–90 °C in 1 °C steps. 70 kW delivered via 10 kW groups with 3-second intervals; runtime-based sequencing balances wear.

Cascade operation and integration

Ideal for cascade arrays where parallel boilers provide scalable capacity with minimal plant modifications.

Safety and uptime

Real-time pressure/temperature monitoring, staged element shutdowns and full isolation under critical conditions—engineered for 24/7 duty.

Audience and deployment

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

Support from Hewa

Engineering support, documentation and dependable logistics for on-time commissioning.
