Cooling Unit Rittal SK 3185.530 — 1600 W, Built-in display, Steel housing, 110–240 / 380–480 V

Rittal SK 3185.530 is an industrial cooling unit designed to control temperatures inside electrical enclosures and control cabinets. With 1600 W cooling capacity, a built-in display for direct controller access and a robust steel housing finished in grey, the unit supports dual input voltage ranges (110–240 V and 380–480 V) at 50/60 Hz. It is intended for use where precise heat dissipation and reliable climate control are required in industrial environments.

Advantages

The cooling unit offers 1600 W of cooling power suitable for medium to large enclosures, and the integrated display provides straightforward access to controller settings without extra tooling. The steel housing ensures mechanical protection and durability in industrial settings, while support for both low and high voltage supply makes installation flexible across different sites. The design focuses on consistent enclosure climate control and efficient heat removal from electrical and electronic components.

Suitable for

• Control cabinets and electrical panels requiring active cooling
• Industrial housings with medium to high heat loads
• Applications that need an on-device display for controller adjustments
• Sites with either 110–240 V or 380–480 V power supply

When it may not be suitable

This cooling unit may not be suitable for very small enclosures with minimal heat dissipation needs, where passive cooling or smaller cooling units would be more energy efficient. It is not intended as a standalone room air conditioner and should be used only for enclosure climate control. For environments requiring explosion-proof or specialized hazardous-area certification, check compatibility with site requirements before selection.

Key specifications

• Cooling capacity: 1600 W
• Built-in display for controller access
• Housing material: steel, grey finish
• Supply voltage ranges: 110–240 V and 380–480 V, 50/60 Hz
• Application: enclosure climate control and heat dissipation

How to use

Mount the unit on the enclosure following the manufacturer's mounting guidelines and ensure the housing opening and sealing meet the enclosure's ingress protection requirements. Connect the supply to the appropriate voltage range and configure the controller settings via the built-in display to match the desired internal temperature and fan control parameters. Regularly inspect air inlets and outlets for dust and debris, and perform maintenance such as filter cleaning or replacement according to service intervals to maintain cooling performance.

What to consider before purchase

• Verify the enclosure internal heat load to confirm 1600 W cooling is appropriate
• Confirm your site's supply voltage (110–240 V or 380–480 V) and compatibility
• Check enclosure cut-out dimensions and mounting compatibility with the unit
• Consider maintenance access for filter cleaning and display operation

Usage recommendations

For reliable performance, size the cooling unit to the measured heat dissipation of the enclosure, maintain clear airflow around air inlets and outlets, and set controller parameters to prevent condensation. Schedule regular maintenance to keep filters and heat exchange surfaces clean and verify electrical connections periodically.
