SK3336.450 Rittal BLUE E CHILLER 25 KW STAND-ALONE

Why Choose the Rittal SK 3336.450 Blue e Chiller?

The Rittal SK 3336.450 is a high-performance Blue e stand-alone industrial chiller designed for centralised and economical cooling of liquid media in demanding industrial machinery, automation and process applications. As part of the proven Rittal Blue e chiller series, it combines robust industrial construction, microchannel heat exchanger technology and intelligent electronic control for reliable continuous cooling.

The Blue e chiller platform uses microchannel technology to reduce the quantity of refrigerant required while maintaining effective heat transfer. An integrated touch display provides intuitive operation and analysis, while intelligent communication interfaces and built-in remote monitoring support integration into modern industrial control and maintenance environments. Integrated safety functions further enhance operational reliability.

With a total cooling output of 24 kW at 50 Hz and 26 kW at 60 Hz to DIN EN 14511 at Tw18/Tu35, the SK 3336.450 provides approximately 25 kW-class cooling performance. It operates from a 400 V three-phase, 50 Hz supply or a 460 V three-phase, 60 Hz supply and is housed in a robust stand-alone enclosure measuring 760 × 1265 × 1515 mm (W × H × D).

High-Capacity Centralised Cooling for Industrial Applications

Industrial chillers such as the Rittal Blue e SK 3336.450 circulate temperature-controlled liquid between the chiller and connected machinery, air/water heat exchangers or process equipment. This allows large thermal loads to be removed efficiently while helping maintain stable operating conditions for temperature-sensitive equipment.

The Blue e platform combines high cooling capacity with microchannel refrigeration technology, integrated monitoring and intelligent controls in a robust stand-alone enclosure. Its substantial coolant flow, built-in reservoir and remote-monitoring capability make the SK 3336.450 suitable for demanding production environments requiring reliable centralised cooling.

Typical Applications

• Industrial machinery and machine tools.
• Manufacturing and production equipment.
• Centralised process cooling systems.
• Spindle, drive and motor cooling.
• Power electronics and electrical equipment cooling.
• Air/water heat exchanger systems.
• Automation installations requiring high-capacity liquid cooling.
