## Summary description

Rittal SK 3188.640 is an industrial cooling unit with a built-in display, designed for enclosure temperature control. It delivers 4000 W input power and operates on 380–480 V, 50/60 Hz. Housed in a grey steel cabinet, the unit suits electrical cabinets and control panels that require reliable heat dissipation and precise temperature monitoring.

## Long description

The Rittal SK 3188.640 cooling unit with built-in display is a compact climate-control device for electrical enclosures and control cabinets. Designed to provide stable temperature management, it delivers 4000 W cooling capacity and is intended for industrial applications that require consistent heat dissipation and straightforward monitoring. The device is supplied for 380–480 V, 50/60 Hz operation and is mounted in a steel housing finished in grey to match typical rack and cabinet environments.
Advantages
The unit combines a high cooling output with integrated temperature display for quick visual checks of enclosure conditions. Its steel housing offers mechanical robustness and compatibility with standard industrial mounting, while the wide input voltage range and both 50 Hz and 60 Hz support make it suitable for varying electrical infrastructures. The design emphasizes reliable performance for continuous operation in demanding environments.
Suitable for
 Cooling electrical enclosures and control panels in industrial settings
 Heat dissipation for power electronics, drives, and PLC cabinets
 Applications requiring built-in temperature readout and control
 Installations with 380–480 V mains and mixed 50/60 Hz frequency
When it may not be suitable
This unit is intended for cabinet and enclosure cooling and may be unnecessary for small, low-heat equipment or consumer electronics that do not generate significant internal heat. It is not designed as a room air conditioner and should not be used to condition open indoor spaces. For systems with cooling requirements below the rated capacity, a smaller unit would be more energy-efficient.
Key specifications
 Cooling capacity: 4000 W (nominal)
 Supply voltage range: 380–480 V
 Frequency: 50/60 Hz
 Housing material: steel
 Housing color/finish: grey
 Integrated display for temperature monitoring
 Mounting type: enclosure/wall-mount compatible
How to use
Mount the cooling unit on the enclosure or cabinet according to the manufacturer's installation guidelines, ensuring correct airflow paths and secure mechanical attachment. Connect the electrical supply matching the specified voltage and frequency, and configure the display and control settings to the target enclosure temperature. Regularly check the built-in display to verify operating temperature and inspect the unit for dust or debris that could impede heat transfer.
What to consider before purchase
 Confirm your enclosure's heat load and compare it to the unit's 4000 W cooling capacity
 Verify mains voltage (380–480 V) and frequency (50/60 Hz) compatibility on site
 Check available mounting space and housing material requirements for your cabinet
 Plan for routine maintenance access to filters and heat-exchange surfaces
Usage recommendations
For reliable operation, ensure adequate enclosure sealing to direct airflow through the cooling unit, schedule periodic cleaning of air paths and filters, and monitor the built-in display to maintain target temperatures. When deploying multiple units, distribute them to optimize airflow and avoid short-circuiting intake and exhaust streams.
