THERMOGYM STAINLESS STEEL COILS FOR INDUSTRIAL DISHWASHING & HEAT PUMP WASH SYSTEMS

High-Performance Thermal Solutions for Commercial Cleaning Applications

Contents


Industrial Dishwasher Performance

Thermogym 316L stainless steel coils are specifically engineered to meet the extreme thermal and chemical demands of commercial dishwashing systems. These systems operate at high throughput, with conveyor and rack-type dishwashers reaching wash temperatures of 90°C and final rinse temperatures exceeding 180°C. Our coils are designed to tolerate repeated exposure to these extremes.

Unlike copper, which rapidly degrades in hard water above 5g/L hardness, Thermogym stainless steel performs reliably even in 20–30g/L environments. The coils withstand frequent contact with caustic detergents (up to pH 13.5) and acidic rinses (as low as pH 2.0), while maintaining structural integrity over 50+ thermal cycles per day. Real-world installations in hospital sterilization kitchens report service lives exceeding 8–10 years, a threefold improvement over traditional copper designs.

Heat Pump-Driven Wash Systems

Modern heat pump dishwashing systems demand heat exchangers that combine high energy efficiency with resistance to chemical attack and temperature cycling. Thermogym coils deliver consistent performance at 65°C wash and 75°C dry phases, enabling compliance with EN 50242 energy ratings while reducing operating costs.

Our coils support commercial systems rated at 50–100kW, with heat pump COPs between 3.8 and 4.2. Thanks to turbulator-enhanced internal surfaces, heat transfer efficiency remains above 92% after 10,000 operating hours. This compares favorably to copper heat exchangers, which often degrade below 60% due to fouling and corrosion. The coils are fully compatible with integrated hot-air drying modules operating between 120°C and 140°C.

Automotive Wash Applications

Vehicle wash tunnels and high-pressure bays present unique challenges due to chemical exposure, temperature fluctuation, and mechanical stress. Thermogym stainless steel coils meet these demands with robust resistance to wheel acid cleaners (pH 1.5–3.0), alkaline degreasers, and road salt spray. Tested to 5,000 hours in salt fog chambers, the coils show no measurable corrosion or performance loss.

They operate reliably in ambient temperatures ranging from -20°C to 80°C, essential for outdoor or unheated wash bays. Fins are mechanically affixed to resist 25 meters-per-second airflow in tunnel dryer systems, eliminating the risk of vibration or fin loosening. These characteristics make Thermogym coils an ideal choice for car wash OEMs seeking durable, low-maintenance solutions.

Chemical & Temperature Resistance

Cleaning environments often include aggressive combinations of sanitizers, oxidizers, and rapid heating or cooling. Thermogym’s 316L stainless steel demonstrates industry-leading chemical resilience, including continuous exposure to chlorine-based sanitizers (200 ppm), up to 50,000 cycles of quaternary ammonium disinfectants, and regular rinses with phosphoric or nitric acid-based agents.

The material tolerates thermal shocks from -20°C to 150°C within one minute, far exceeding copper’s threshold for thermal fatigue. Corrosion rates remain below 0.1 mm/year in acidic environments where copper often exceeds 1.2 mm/year. This resilience translates to safer operation, reduced maintenance intervals, and lower total cost of ownership.

Operational Advantages vs. Copper

When directly compared with copper-based systems, Thermogym stainless steel coils offer superior performance in every category relevant to industrial dishwashing. They provide a 300% longer service life in hard water or aggressive chemical environments, entirely eliminating the need for protective coatings or post-installation sealing.

Energy consumption is reduced by 15–20% due to better thermal stability and less performance degradation over time. The coils are fully compatible with ozone sanitation protocols and resist biofilm formation in low-flow rinse zones. End-of-life recyclability further contributes to environmental and economic sustainability, supporting green building goals and circular economy initiatives.
