Silox — Stainless steel twin wall
DHW cylinders for efficient hot
water production

The Silox cylinders are built around the innovative twin wall concept, where a primary outer tank transfers heat to the inner DHW cylinder across its full surface area. This design maximises heat exchange, ensuring faster reheat times and constant hot water availability. The inner cylinder is corrugated to create natural expansion and contraction during operation, producing a self-cleaning effect that reduces scale deposits and maintenance needs while preserving long-term performance.

To further enhance efficiency, Silox cylinders are insulated with CFC- and HCFC-free polyurethane foam, injected directly to guarantee uniform thickness and density. This advanced insulation minimises heat losses, outperforming even the strict requirements of DIN 4753/8. For added flexibility, models up to 1000 litres can be equipped with an immersion heater of up to 12 kW, ensuring a dependable backup source of hot water in every installation scenario.

With a state-of-the-art CNC machine park, we handle the entire metalworking process in-house – from R&D designs to bending, shaping, and welding (including laser and diffusion methods). Our laboratories ensure the highest weld quality, while a digital tracking system guarantees full component traceability. We work mainly with stainless steel, as well as titanium, copper, and other certified metals from European suppliers.
