Cooling unit Rittal SK 3185.835, built-in display, 1600 W, steel grey, 110–240/380–480 V, 50/60 Hz

The Rittal SK 3185.835 is a built-in cooling unit designed to control enclosure climate in industrial and commercial installations. With a nominal cooling capacity of 1600 W and an integrated display, the unit allows monitoring and adjustment of temperature settings from the enclosure front. The housing is steel grey and the electrical input accepts both single-phase and three-phase supplies (110–240 V and 380–480 V) at 50/60 Hz, making it compatible with a wide range of site power configurations.

Advantages

The cooling unit provides a reliable 1600 W cooling capacity suitable for medium-duty thermal management in control cabinets and electrical enclosures. The built-in display offers local status readout and parameter adjustment without additional accessories. Its universal voltage acceptance supports flexible installation on sites with either single-phase or three-phase mains, and the steel grey housing is durable for industrial environments.

Suitable for (tasks / use cases)

• Cooling electrical cabinets and control panels in production and automation systems
• Reducing internal temperatures for drives, PLCs, and frequency converters
• Retrofit or new installations where a built-in cooling solution with display is required
• Enclosures located in machine rooms, workshops, or commercial buildings with 110–240 V or 380–480 V supply

When it may not be suitable

This built-in cooling unit is intended for enclosure installation and may not be suitable for open-frame electronics or equipment racks that require directed airflow or spot cooling. It is also designed for fixed mounting in cabinets and is not intended as a portable or spot air conditioner for occupied spaces.

• Cooling capacity: 1600 W
• Integrated front display for monitoring and control
• Operating voltage: accepts 110–240 V and 380–480 V inputs
• Frequency: 50/60 Hz
• Mounting type: built-in for enclosure installation
• Housing color/finish: steel grey

How to use

Mount the unit into the enclosure cutout according to the cabinet manufacturer’s instructions and ensure correct electrical connection to the appropriate supply (single-phase or three-phase) by a qualified electrician. Use the integrated display to set the desired cabinet temperature and view operating status. Verify that the unit’s air intake and exhaust paths inside the cabinet are unobstructed and that internal airflow is arranged to avoid hot spots. Regularly check filters and external vents and perform maintenance according to the manufacturer’s service recommendations.

What to consider before purchase

• Confirm that the cabinet has a compatible cutout and mounting provisions for a built-in cooling unit
• Verify that the available mains supply matches the unit’s accepted voltage range (110–240 V or 380–480 V)
• Ensure the 1600 W cooling capacity meets the enclosure’s heat dissipation requirements
• Plan for access to the integrated display for monitoring and adjustment after installation

Usage recommendations

Install the unit in an upright position inside a sealed enclosure, maintain clear intake and exhaust paths, and schedule periodic inspections of filters and condensate drainage if applicable. For best performance, size the cooling capacity to exceed the calculated heat load of installed components and consult the enclosure manufacturer’s guidelines for cutout and mounting details.
