Built-in 2000 W Cooling Unit Rittal SK 3186.935 — 110–240 / 380–480 V, 50/60 Hz, Steel Housing, Grey

The Rittal SK 3186.935 is a built-in 2000 W cooling unit designed for control cabinets and electrical enclosures. It supports supply voltages of 110–240 V or 380–480 V at 50/60 Hz and is housed in a grey steel casing with an integrated display for monitoring operating status and temperature. This appliance is intended to stabilize internal cabinet temperatures in industrial and commercial installations where precise thermal management is required.

Advantages

This cooling unit provides consistent cooling power of 2000 W suitable for medium to large enclosures. The dual-voltage capability (110–240 V and 380–480 V) and compatibility with both 50 Hz and 60 Hz mains frequencies make it flexible for international installations. The steel housing delivers mechanical robustness and electromagnetic shielding, while the integrated display simplifies local monitoring and basic adjustment of operating parameters.

Suitable for

• Control cabinets and switchgear in industrial plants
• Telecommunications and server cabinets requiring active cooling
• Commercial electrical enclosures in manufacturing and processing facilities
• Applications where a compact, built-in cooling solution is required

When it may not be suitable

The SK 3186.935 is intended for built-in installation into enclosures with appropriate mounting provisions; it may not be suitable for retrofit applications that lack space or cutouts for integration. It is a dedicated cabinet cooling unit and not designed as a room air conditioner or for direct cooling of stand-alone equipment outside enclosures.

Key specifications

• Cooling capacity (input power): 2000 W
• Supply voltage range: 110–240 V or 380–480 V
• Mains frequency: 50/60 Hz
• Housing material: steel
• Colour: grey
• Mounting type: built-in for enclosure integration
• Integrated display for monitoring and basic control

How to use

Install the unit into the prepared cutout of the control cabinet following the enclosure manufacturer’s mounting recommendations and local electrical codes. Connect the cooling unit to the appropriate supply voltage (verify whether the installation uses the 110–240 V or 380–480 V range) and ensure correct earthing. Use the integrated display to set desired temperature or operating mode and to monitor status. Regularly check filters and airflow paths and perform maintenance according to Rittal guidelines to maintain performance and prevent overheating of cabinet components.

What to consider before purchase

• Available space and cutout dimensions in the enclosure for built-in installation
• The supply voltage on site (110–240 V or 380–480 V) and compatibility with the unit
• Required cooling capacity relative to cabinet heat load and equipment dissipation
• Ambient conditions, humidity, and presence of corrosive chemicals that may require special versions

Usage recommendations

Match the cabinet’s heat load to the 2000 W cooling capacity and allow for service access and filter maintenance. Verify electrical connections and grounding before commissioning. Monitor the integrated display after installation to confirm stable operation and schedule periodic inspections to ensure reliable thermal management of enclosure components.
