Rittal SK 3336390 Built-in display industrial chiller — input 5260 W, cooling capacity 7090 W, 400/460 V, 50/60 Hz, steel housing, grey

Rittal SK 3336390 is a built-in industrial chiller with an integrated display designed for enclosure and process cooling. With a rated cooling capacity of 7090 W and an input power of 5260 W, the unit is compatible with 400/460 V supply at 50/60 Hz. The chiller is built in a steel housing with a grey finish and stainless-steel elements and is intended for applications where reliable heat removal from control cabinets, switchgear and process equipment is required.

Advantages

The chiller features microchannel technology that reduces the required refrigerant volume and supports efficient heat transfer. An integrated touch display provides intuitive operation and access to operating information. Remote monitoring and intelligent communication interfaces are pre-integrated to enable system analysis and remote diagnostics. Built-in safety functions come as standard and the product is available in predefined option packages to shorten delivery and simplify selection.

Suitable for

• Cooling of electrical enclosures and switchgear
• Process cooling in industrial control cabinets
• Data centre auxiliary cooling for equipment racks
• Applications requiring centralised cooling with built-in display and remote monitoring

When it may not be suitable

This built-in chiller is intended for integration where a compatible electrical supply (400/460 V, 50/60 Hz) and sufficient installation space are available; it may not be suitable for low-voltage systems or installations lacking appropriate mounting arrangements. For extremely small enclosures or applications that require cooling capacities much lower than 7090 W, a smaller dedicated cooling device could be more appropriate.

How to use

Install the Rittal SK 3336390 as a built-in unit into an appropriate enclosure or panel according to the manufacturer's mechanical and electrical installation instructions. Connect the unit to a compatible 400/460 V, 50/60 Hz supply and integrate the chiller's communication interface with the facility monitoring system if remote supervision is required. Use the touch display to configure operating parameters, monitor temperatures and view status information. Observe routine maintenance intervals and check for correct refrigerant and coolant circuits as specified by the manufacturer.

What to consider before purchase

• Ensure available electrical supply is 400/460 V and 50/60 Hz compatible with the unit
• Verify installation space and mounting compatibility for a built-in chiller in steel housing
• Confirm required cooling capacity aligns with the rated 7090 W
• Plan for integration of remote monitoring and communication into existing control systems
• Check access for maintenance and service of touch display and safety components

Usage recommendations

For reliable operation, place the chiller in an environment that meets ventilation and ambient temperature requirements, follow the manufacturer’s installation and maintenance guidelines, and use the integrated communication interfaces to enable remote monitoring and early fault detection.
