Rittal SK 3214700 Air/Water Heat Exchanger 650 W, 34 W Input, 230 V, 0.111 l/s, Stainless Steel, Built-in Display

The Rittal SK 3214700 Air/Water Heat Exchanger provides air-to-water cooling for electrical enclosures and industrial housings with a rated cooling capacity of 650 W. Constructed from stainless steel and finished in grey, the unit is intended for wall-mounted installation and includes a built-in display for monitoring. It operates from a 230 V, 50–60 Hz supply with an input power of 34 W and an airflow of 0.111 l/s, offering controlled temperature management for cabinets used in hygienic or industrial environments.

Advantages

The stainless steel housing and cleaning-friendly design reduce contamination risk in hygiene-critical production zones, making it compatible with environments such as food and beverage processing. The unit’s built-in display allows local observation of operating status. Low input power (34 W) and a compact, wall-mounted form factor simplify integration into existing enclosures while providing a rated cooling capacity of 650 W.

Suitable for

• Cooling electrical control cabinets and industrial housings in hygienic production areas
• Applications that require air-to-water heat removal where stainless steel construction is preferred
• Wall-mounted installations where built-in display and compact footprint are needed

When it may not be suitable

This heat exchanger is designed specifically for air-to-water cooling and requires connection to an appropriate water circuit; it is not a standalone refrigeration unit. It may not be suitable where higher cooling capacities than 650 W are required or where alternative mounting orientations are necessary.

Key specifications

• Cooling capacity: 650 W
• Input power: 34 W
• Supply voltage: 230 V, 50–60 Hz
• Airflow: 0.111 l/s
• Material: stainless steel
• Mounting: wall-mounted, built-in display

How to use

Install the heat exchanger on a suitable wall or enclosure surface following applicable mounting instructions and ensure the unit is connected to the facility water circuit designed for heat rejection. Connect the electrical supply at 230 V, 50–60 Hz and verify power input remains within specified limits. Use the built-in display to monitor operating status and adjust any control settings per site requirements. Perform routine cleaning of the stainless steel surfaces and inspect seals to maintain hygiene and thermal performance.

What to consider before purchase

• Availability of an appropriate water circuit for air-to-water heat rejection
• Required cooling capacity relative to the unit’s 650 W rating
• Compatibility of stainless steel construction and cleaning procedures with site hygiene standards
• Space and mounting location for a wall-mounted unit with a built-in display

Usage recommendations

For hygiene-critical environments, follow the manufacturer’s cleaning protocols and ensure that run-off and drainage are configured to avoid contamination. Verify water circuit parameters and maintain scheduled inspections of seals and the display to ensure continuous, reliable cooling performance.
