Rack cooling unit Rittal 3318.610 TopTherm standalone chiller, plastic housing, 600×455×400 mm, grey

The Rittal 3318.610 TopTherm standalone rack cooling unit is a compact chiller for targeted climate control inside enclosures and server cabinets. Housed in a grey plastic cabinet with external dimensions of 600 × 455 × 400 mm, this TopTherm model is intended for small to medium racks where a self-contained cooling solution is required. It delivers chilled cooling capacity for electronic components and IT equipment and is supplied with a nano-coated condenser and an integrated pump to convey the cooling medium.

Advantages

This standalone chiller features a compact, modular refrigeration layout designed for efficient integration into rack environments. The nano-coated condenser provides improved resistance to contamination and supports longer service intervals in environments with airborne particles. Precise temperature control is achieved through microprocessor-based regulation, and the unit provides a collective fault signal via a floating contact to support remote monitoring. The built-in pump simplifies connection to internal air/water heat exchangers and avoids the need for a separate external pump in many installations.

Suitable for (tasks / use cases)

• Temperature control of small to medium server and network cabinets
• Cooling of electronic control enclosures in industrial or IT environments
• Applications where a self-contained, roof-mounted or standalone chiller is preferred
• Systems requiring a compact unit with integrated pump and microprocessor temperature regulation

When it may not be suitable

This unit is intended for localized rack or enclosure cooling and may not provide sufficient capacity for large data center rooms or installations that require centralized high-capacity chillers. Installations that demand redundant multi-stage cooling or integration into complex central refrigeration systems should be evaluated for compatibility before choosing this standalone model.

Key specifications

• Housing material: plastic
• Color: grey
• External dimensions (W × D × H): 600 × 455 × 400 mm
• Condenser: nano-coated condenser for improved contamination resistance
• Integrated pump to convey the cooling medium
• Temperature control: microprocessor-based regulation for precise setpoint control
• Fault signalling: collective fault contact (floating contact) for remote monitoring
• Design: compact, modular refrigeration component layout

How to use

Install the TopTherm unit as specified for roof-mounted or standalone operation in accordance with local installation regulations and Rittal installation instructions. Connect the integrated pump and piping to the enclosure’s air/water heat exchanger or cooling circuit, and provide electrical connection to the unit’s supply consistent with its rated input. Configure the microprocessor temperature control to the required setpoint and verify the collective fault contact is connected to the facility monitoring system if remote alarm functionality is required. Commission the unit by checking for correct coolant flow, secure electrical connections and normal operation of the condenser and compressor.

What to consider before purchase

• Required cooling capacity for the target rack or enclosure to ensure adequate performance
• Compatibility with existing enclosure heat exchangers or rack layout for roof-mounted or standalone installation
• Electrical supply requirements and whether the local supply matches the unit’s frequency/voltage capabilities
• Service access and maintenance space around the unit for filter and condenser inspection

Usage recommendations

Use the TopTherm chiller for dedicated enclosure cooling where compact, self-contained operation and precise temperature control are needed. Maintain regular inspections of the nano-coated condenser and pump circuit, and follow Rittal service intervals to ensure consistent cooling performance.
