Cooling heat exchanger for water cooling system Rittal SK wall-mountable RAL 7035

The Rittal SK cooling heat exchanger for water cooling systems is a wall-mountable unit finished in RAL 7035, intended for integration into industrial cooling setups. Designed to connect to a facility water circuit, it transfers heat from electrical enclosures or equipment to the building's water system to maintain regulated internal temperatures. The unit is suitable for installations where a compact, externally mounted heat removal solution is required for cabinets, control panels, or small machinery.

Advantages

This heat exchanger offers direct water-circuit heat rejection, enabling efficient temperature control without additional refrigerant-based components. Its wall-mountable design saves floor space and simplifies placement near enclosures. The neutral RAL 7035 finish provides visual compatibility with standard industrial cabinets. Intended for industrial environments, the unit is constructed for straightforward connection to existing water supply and return lines, supporting continuous operation where water-based heat removal is preferred.

How to use

Install the heat exchanger on a suitable wall surface close to the enclosure or equipment to be cooled, following structural load and clearance requirements. Connect inlet and outlet ports to the facility water supply and return lines using appropriate fittings and hoses compatible with the water quality and pressure in the system. Ensure valves, strainers and isolation points are provided in the piping for commissioning and maintenance. Commission the circuit, check for leaks, and verify flow rates and temperature differentials to confirm effective heat transfer.

Recommendations

Use corrosion-resistant piping and follow local regulations for water treatment and pressure systems. Regularly inspect connections and seals, and maintain recommended water quality to prevent fouling or scale formation that can reduce heat-exchanger performance.
