Rittal SK 3383.500 roof-mount cooling unit, steel housing, 230 V input, grey

The Rittal SK 3383.500 roof-mount cooling unit is a compact cooling solution with a steel housing and grey finish designed for 230 V input. Intended for mounting on the roof of electrical enclosures and control cabinets, this unit maintains controlled interior temperatures to protect sensitive electronic and electrical components from overheating. The design focuses on consistent cooling performance for industrial and commercial installations where temperature management is required.

Advantages

The steel housing provides robust mechanical protection and long service life in standard indoor industrial environments. Designed for 230 V supply, the unit integrates with common electrical infrastructures. Its roof-mount configuration simplifies installation on cabinets and enclosures, directing cooled air into the interior space while keeping the cooling equipment outside the enclosure to reduce internal heat sources.

Suitable for

• Cooling electrical cabinets and control panels in industrial facilities
• Maintaining temperature-stable environments for PLCs, drives, and communication equipment
• Commercial installations where a roof-mounted cooling approach is preferred
• Enclosures that require reliable, continuous temperature control at 230 V supply

When it may not be suitable

This roof-mount cooling unit is intended for use on cabinets where a dedicated 230 V supply is available and where ambient conditions fall within the unit's operational limits. It may not be suitable for outdoor enclosures exposed to extreme weather, corrosive atmospheres, or areas requiring specialized ingress protection beyond standard indoor industrial ratings.

Key specifications

• Mounting type: roof-mount for electrical enclosures
• Housing material: steel
• Finish: grey
• Supply voltage: 230 V
• Application: enclosure cooling for control cabinets and electrical panels

How to use

Install the unit on the roof panel of the enclosure according to the cabinet manufacturer’s cutout and mounting instructions, ensuring secure mechanical attachment and correct sealing to prevent ingress. Connect the unit to a 230 V supply following local electrical codes, and configure any temperature control or fan settings as required by the internal equipment’s thermal limits. Regularly inspect filters, air inlets and outlets, and the housing for dust or debris and perform maintenance according to the manufacturer’s schedule to sustain cooling performance.

What to consider before purchase

• Verify cabinet cutout dimensions and roof-mount compatibility
• Confirm the unit’s cooling capacity matches the enclosure’s heat load
• Ensure a compatible 230 V electrical supply and proper wiring provisions
• Assess ambient conditions and required protection level for the installation site

Usage recommendations

For reliable operation, pair the roof-mount cooling unit with regular preventive maintenance: clean or replace air filters, check sealing and mounting integrity, and verify electrical connections. Use temperature monitoring inside the enclosure to adjust setpoints and detect cooling issues early.
