Rittal SK 3336435 Built-in display Industrial Chiller, Input 12850 W, Cooling up to 21200 W, 400/460 V, 50/60 Hz, Grey, Steel

The Rittal SK 3336435 Built-in display Industrial Chiller is a compact, enclosure-mounted cooling unit designed for reliable temperature control in industrial environments. With an input power of 12,850 W and a maximum cooling capacity up to 21,200 W, this steel-bodied chiller operates on 400/460 V at 50/60 Hz and includes an integrated touch display for intuitive control. The Blue e series design uses microchannel heat exchanger technology to reduce refrigerant volume while maintaining efficient heat transfer, and the unit includes stainless steel components in critical areas for improved durability.

Advantages

The integrated touch display simplifies commissioning and daily operation, while pre-configured option packages shorten delivery and setup time. Microchannel technology reduces the refrigerant required and contributes to efficient cooling performance. Built-in safety features and remote monitoring interfaces provide transparent system status and help protect connected equipment. The steel housing with grey finish and stainless steel parts offers mechanical robustness suitable for industrial and data center environments.

Suitable for (tasks / use cases)

• Cooling control cabinets and electrical enclosures in industrial plants
• Process cooling for small to medium industrial applications
• Temperature-stable cooling for data centers and server racks
• Machine tool and automation system cooling
• Centralised chilled water supply in secondary cooling loops

When it may not be suitable

This built-in chiller is intended for enclosure and process cooling; it may be unsuitable where free-standing, large-capacity central chillers or bespoke process chillers are required beyond its rated cooling capacity. Very small applications with minimal heat load may be overdimensioned for this unit, and installations that cannot provide the specified 400/460 V, 50/60 Hz supply will require alternative equipment or transformers.

Key specifications

• Cooling capacity up to 21,200 W
• Input power 12,850 W
• Supply voltage 400/460 V, 50/60 Hz
• Built-in touch display for local operation
• Microchannel heat exchanger technology to reduce refrigerant volume
• Steel housing with grey finish and stainless steel components in critical areas
• Integrated safety functions and pre-configured option packages
• Pre-integrated remote monitoring and communication interfaces

How to use

Install the chiller as a built-in unit in the intended enclosure or rack space following the manufacturer’s mounting and clearance guidelines. Connect the unit to the appropriate 400/460 V, 50/60 Hz electrical supply and to the cooled water loop according to system hydraulics. Use the integrated touch display for initial configuration, setting target fluid temperatures, alarms and operating modes. Verify safety interlocks and remote monitoring connections during commissioning. Regularly inspect coolant circuits, filters and fans and follow the prescribed maintenance intervals to maintain rated performance.

What to consider before purchase

• Ensure available electrical supply: 400/460 V, 50/60 Hz
• Confirm required cooling capacity matches unit rating (up to 21,200 W)
• Check enclosure space and mounting requirements for a built-in unit
• Plan for hydraulic connections and chilled water loop design
• Evaluate remote monitoring and communication needs and integration

Usage recommendations

For reliable operation, select piping and pump sizes that match the chiller’s hydraulic specifications, perform periodic checks on the microchannel heat exchanger and ensure ambient conditions remain within the recommended range. Use the touch display to monitor trends and alarms; integrate the unit with building or process monitoring systems for proactive maintenance.
