Rittal SK 3216480 Wall-mounted Air/Water Heat Exchanger, 7000 W, 400/480 V, 0.1389 l/s airflow

The Rittal SK 3216480 wall-mounted air-to-water heat exchanger is designed to remove heat from electrical enclosures and industrial control cabinets. Built for use in harsh environments, the unit offers a maximum cooling capacity of 7000 W and is intended to maintain stable internal temperatures in switchgear, control panels and similar cabinets. The housing is stainless steel with a grey finish and the device integrates a thermostat-controlled magnetic valve for regulated coolant flow.

Advantages

This wall-mounted heat exchanger delivers high cooling capacity in a compact installation format, enabling effective temperature control without requiring large external chillers. The stainless steel construction provides corrosion resistance suitable for demanding industrial settings. The built-in thermostat-controlled magnetic valve allows automatic regulation of the water circuit based on enclosure temperature, improving energy efficiency and preventing unnecessary cooling cycles. Designed for 400/480 V electrical systems and low operating current, it is compatible with standard industrial power supplies.

Suitable for

• Cooling electrical enclosures, control panels and switchgear in industrial facilities
• Applications requiring a 7000 W cooling capacity within a compact, wall-mounted unit
• Environments where stainless steel construction and resistance to harsh conditions are needed
• Systems using a water cooling loop with thermostat-controlled valve integration

When it may not be suitable

This heat exchanger is not suitable for standalone cooling of large rooms or processes that require airflow volumes far above the specified 0.1389 l/s. It also requires a compatible water cooling circuit and appropriate plumbing; sites without a closed-loop water system or access to a chilled-water supply will need additional equipment to use this unit.

Key specifications

• Cooling capacity: 7000 W (max)
• Airflow: 0.1389 l/s
• Supply voltage: 400/480 V, 50/60 Hz
• Operating current: 1.2 A
• Material: stainless steel housing, grey finish
• Mounting: wall-mounted
• Control: thermostat-controlled magnetic valve for coolant flow regulation
• Intended use: air-to-water heat exchange for electrical enclosures and industrial cabinets

How to use

Mount the heat exchanger securely on a suitable wall adjacent to the electrical enclosure following the manufacturer’s mounting instructions and local safety codes. Connect the unit to the facility’s water cooling loop and electrical supply (400/480 V, 50/60 Hz). Set the thermostat to the desired enclosure temperature; the magnetic valve will open and close to regulate coolant flow and maintain stable internal temperatures. Regularly inspect inlet and outlet connections, the valve function, and the external housing for signs of corrosion or leaks. Perform preventive maintenance according to operating hours and environmental conditions to ensure continuous performance.

What to consider before purchase

• Availability of a compatible closed-loop water cooling circuit or chilled-water supply
• Electrical supply compatibility: 400/480 V, 50/60 Hz and appropriate current protection
• Space and structural capability for secure wall mounting near the enclosure
• Required cooling capacity for your enclosure to verify that 7000 W is sufficient

Usage recommendations

Install with appropriate isolation valves and filtration on the water circuit, and ensure the thermostat setpoint matches the thermal limits of the enclosed equipment. Schedule periodic checks of the magnetic valve operation and water connections to prevent downtime due to leaks or reduced cooling performance.
