Enclosure / Wall-Mount Cooling Unit Rittal SK 3328.540 – Steel housing, Grey, 2000 W (model series info)

Rittal SK 3328.540 is a wall-mount cooling unit engineered for control cabinets and enclosures that house electrical and electronic equipment. Housed in a grey steel cabinet, this 2000 W cooling unit is designed to extract heat from enclosed spaces and integrate with existing ventilation arrangements to maintain reliable operating temperatures for industrial automation, control systems and electrical distribution panels.

Advantages

The steel housing offers mechanical robustness and corrosion resistance suitable for industrial environments. With a 2000 W cooling capacity, the unit supports continuous heat removal for medium-duty enclosures. Designed for wall-mount installation, it saves internal cabinet space and connects to standard enclosure openings for straightforward integration. The unit is supplied as a single, complete device that simplifies installation and reduces the need for additional components.

Suitable for

• Control cabinets and electrical enclosures in manufacturing and automation
• Panels with heat-generating components such as power supplies, drives or PLCs
• Environments requiring a compact, wall-mounted cooling solution
• Applications where maintaining stable internal temperatures is important for component reliability

When it may not be suitable

This cooling unit is intended for moderate to medium thermal loads; it may not be adequate for very large enclosures or setups with extreme heat generation that require higher-capacity or distributed cooling solutions. Also, installations that demand ingress protection ratings beyond the unit’s capabilities or specialized hazardous-area approvals should verify compatibility before selection.

Key specifications

• Mounting type: wall-mount for external installation on enclosures
• Housing material: steel with industrial grey finish
• Cooling capacity: approximately 2000 W (continuous heat removal)
• Supply configuration: single complete cooling unit for direct integration

How to use

Install the cooling unit on the exterior of the control cabinet at the designated cut-out or mounting location following enclosure manufacturer instructions and local electrical regulations. Ensure correct electrical connection and any control wiring is completed by a qualified technician. Position the unit to allow unobstructed airflow through the enclosure and to maintain recommended clearances. Set the temperature controller or comfort regulator to the desired setpoint to begin active cooling; monitor performance during initial operation to confirm stable internal temperatures.

What to consider before purchase

• Verify the heat load of the enclosure and confirm that a 2000 W cooling capacity is sufficient
• Check enclosure cut-out dimensions and mounting compatibility with the wall-mount unit
• Confirm electrical supply requirements and control interface compatibility with the site
• Assess environmental requirements such as ingress protection and ambient temperature range

Usage recommendations

For reliable operation, schedule periodic inspections to keep the cooling air paths and filters clean, and ensure electrical connections remain secure. If heat load or ambient conditions change, re-evaluate cooling capacity and consider additional or higher-capacity solutions where necessary.
