Why Choose the Rittal SK3318.610 TopTherm Chiller?
The Rittal SK3318.610 TopTherm Chiller is a compact stand-alone industrial water chiller designed to provide an economical central cooling-water supply 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 well suited to electrical enclosure, machinery and industrial process cooling applications.
Unlike the sealed-circuit variant, the SK3318.610 features a hermetically open water circuit with an integrated 2.5 l polypropylene tank. A built-in pump circulates the cooling medium through the connected system, while microcontroller-based temperature regulation maintains precise control with a factory setting of +20 °C and temperature hysteresis of ±2 K.
The SK3318.610 operates from a 230 V AC single-phase, 50/60 Hz supply and features a hydrophobic RiNano-coated condenser, floating collective fault contact and IP44 protection for the electrics. Its compact stand-alone design, international dual-frequency compatibility and integrated liquid circuit provide a complete cooling solution ready for connection.

Reliable Open-Circuit 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 SK3318.610 cools a central liquid medium that can be circulated to compatible air/water heat exchangers or other liquid-cooled equipment, transporting heat away from sensitive components and rejecting it through the chiller's refrigeration system.
The hermetically open water circuit incorporates a 2.5 l tank and pump, providing a self-contained medium circulation system. Microcontroller regulation maintains the required cooling-medium temperature, while the 10–30 °C liquid operating range, dual-frequency supply and compact stand-alone format support flexible integration into industrial climate-control installations.
Typical Applications
- Central cooling-water supply for air/water heat exchangers.
- Industrial electrical enclosure cooling.
- Machine tool thermal management.
- Automation and control equipment cooling.
- Industrial process cooling systems.
- Power electronics and drive-system cooling.
- Manufacturing machinery with liquid-cooled components.
- Compact stand-alone chilled-water installations.
