Rittal SK 3336455 Industrial Chiller 14,700 W Input Power, 400/460 V, 50/60 Hz, Grey Steel Housing

The Rittal SK 3336455 Industrial Chiller is a floor-standing cooling unit intended for temperature control of electrical enclosures and process equipment. It provides an input power rating of 14,700 W, operates on 400/460 V at 50/60 Hz and offers a maximum cooling capacity of 26,000 W. The unit is built with a grey steel or stainless-steel housing designed for demanding environments and centralised cooling of cooling water using microchannel technology to reduce refrigerant volume.

Advantages

The chiller integrates microchannel heat exchanger technology to lower the refrigerant charge while maintaining compact dimensions. An intuitive touch display simplifies operation and status checks, and remote monitoring interfaces are pre-integrated for easier system integration and condition analysis. The base unit includes integral safety functions and comes with pre-configured option packages to shorten delivery and commissioning time.

Suitable for (tasks / use cases)

• Cooling electrical control cabinets and switchgear in industrial installations
• Temperature control of process equipment and manufacturing machinery
• Centralised cooling water supply for multiple enclosures or localized cooling loops
• Applications requiring remote monitoring and integration with building or plant control systems

When it may not be suitable

This industrial chiller is designed for use where three-phase supply at 400/460 V and 50/60 Hz is available; it is not suitable for single-phase or lower-voltage mains without appropriate conversion. Environments requiring ultra-low cooling capacities well below the unit’s range or very compact portable cooling solutions may be better served by smaller or specialised chillers.

How to use

Install the chiller on a level, floor-mounted location with adequate clearance for airflow and maintenance access. Connect the unit to a three-phase 400/460 V, 50/60 Hz electrical supply in accordance with local codes and the manufacturer’s installation instructions. Integrate the chiller into the cooling water loop or direct enclosure cooling arrangement and configure the touch display to set target temperatures, alarm thresholds and communication parameters. Use the pre-integrated remote monitoring interfaces to connect the unit to plant control or building management systems for ongoing status monitoring and diagnostics.

What to consider before purchase

• Verify availability of a compatible three-phase 400/460 V, 50/60 Hz power supply and appropriate circuit protection
• Confirm the required cooling capacity for your enclosures or process to ensure the unit’s maximum cooling capacity aligns with demand
• Ensure sufficient floor space and service clearance for a floor-standing unit and plan for maintenance access
• Decide between grey steel or stainless-steel housing based on environmental conditions and corrosion risk
• Check integration requirements for remote monitoring and communication with existing control systems

Usage recommendations

Operate the chiller within the specified supply voltage and frequency ranges, perform regular filter and heat-exchanger maintenance, and use the touch display and remote monitoring features to track performance and alarms. Follow the manufacturer’s maintenance schedule and safety instructions to maintain reliable cooling performance.
