Rittal SK 3336400 Built-in display Grey steel chiller 6830 W input, 12000 W cooling capacity, 400/460 V, 50/60 Hz

Rittal SK 3336400 is an industrial liquid chiller with a built-in display and a grey steel housing designed for reliable cooling in control cabinets, data centres and process systems. The unit delivers up to 12,000 W of cooling capacity while drawing 6,830 W input power and operates on 400/460 V at 50/60 Hz. Constructed from a combination of steel and stainless steel components, this floor-standing chiller uses microchannel technology to reduce refrigerant volume and supports touch-display operation and integrated communication for remote monitoring.

Advantages

The chiller offers a high cooling capacity relative to its footprint and integrates an intuitive touch display for simplified configuration and diagnostics. Microchannel heat exchangers reduce the amount of refrigerant required while maintaining efficient heat transfer. Built-in safety functions and pre-configured option packages shorten commissioning time and support safer operation in industrial environments. Remote monitoring interfaces are pre-integrated to allow straightforward connectivity with control systems and building management platforms.

Suitable for

• Cooling of control cabinets and electrical enclosures in industrial plants
• Temperature control for data centre racks and IT equipment
• Process cooling for machinery, test benches and laboratory equipment
• Centralised cooling installations where floor-standing chillers are required

When it may not be suitable

This chiller may not be appropriate for small-scale or point-of-use cooling needs where lower capacity or a compact, unit-mounted cooler would be preferable. It is designed for floor-standing, centralised installations and requires appropriate electrical supply (400/460 V, 50/60 Hz) and space for installation and service access.

• Heat exchanger technology: microchannel
• Operation interface: touch display
• Remote monitoring: pre-integrated communication interfaces
• Built-in safety functions: standard

How to use

Install the chiller on a level floor with sufficient clearance for airflow and maintenance access, and connect to a compatible electrical supply (400/460 V, 50/60 Hz) by a qualified electrician. Fill and connect the process cooling loop according to the system design and commissioning instructions, ensuring correct pump sizing and flow rate for the desired temperature control. Use the touch display to configure operating parameters, set target temperatures and review status and diagnostic information. Integrate the chiller with a building or process control system via the pre-integrated communication interfaces for remote monitoring and alarms.

What to consider before purchase

• Ensure facility electrical supply matches 400/460 V and 50/60 Hz requirements
• Verify required cooling capacity (up to 12,000 W) suits the application load
• Confirm available floor space and service clearance for a floor-standing unit
• Check compatibility of process fluid, piping connections and pump sizing
• Plan for integration with existing control and monitoring systems

Usage recommendations

Regular preventive maintenance, including cleaning of heat exchanger surfaces, verification of refrigerant circuit integrity and periodic checks of electrical connections and controls, will help maintain cooling performance. Use the touch display to monitor operating parameters and enable remote alarms to promptly detect deviations. Ensure filters, strainers and pumps in the process loop are sized and maintained to prevent flow restrictions and contamination.
