Why Choose the Rittal SK3318.600 TopTherm Chiller?
The Rittal SK3318.600 TopTherm Chiller is a compact stand-alone industrial water chiller designed to provide a reliable central supply of cooled water for air/water heat exchangers and other liquid-cooled equipment. It delivers 1 kW cooling output at 50 Hz and 1.1 kW at 60 Hz under Tw18/Tu32 conditions, making it a practical thermal management solution for machinery, electrical enclosures and industrial process applications.
A compact modular refrigeration system, integrated medium-conveying pump and pressure-sealed water circuit provide a complete cooling solution ready for connection. Precise microcontroller-based temperature regulation maintains the cooling medium around the required setpoint, with a factory setting of +20 °C and a temperature hysteresis of ±2 K.
The SK3318.600 operates from a 230 V AC single-phase, 50/60 Hz supply and measures 600 mm wide × 400 mm high × 430 mm deep. Its condenser features Rittal's hydrophobic RiNano coating, while IP44 protection for the electrics, a floating collective fault contact and dual-frequency operation support dependable integration into industrial cooling systems.

Reliable Central Cooling for Industrial Equipment
Electrical enclosures, machine tools and industrial processes can generate heat loads that are difficult to manage using ambient-air cooling alone. The Rittal SK3318.600 chills a central liquid medium that can be circulated to compatible air/water heat exchangers or other liquid-cooled equipment, allowing heat to be transported away from sensitive components and released through the chiller's refrigeration circuit.
Microcontroller-based regulation maintains precise cooling-medium temperatures, while the integrated pump and pressure-sealed water circuit simplify installation. The 10–30 °C cooling-medium operating range, dual-frequency electrical supply and compact stand-alone format make the SK3318.600 suitable for a broad range of industrial thermal management applications.
Typical Applications
- Central cooling-water supply for air/water heat exchangers.
- Industrial electrical enclosure cooling.
- Machine tool cooling systems.
- Automation and control equipment thermal management.
- Process equipment requiring temperature-controlled cooling water.
- Industrial electronics and power equipment cooling.
- Manufacturing machinery with liquid-cooled components.
- Compact stand-alone industrial cooling installations.
