This air-cooled WKL 230 circulation chiller with a filling volume of 4 to 6L has a closed cooler circuit for continuous nonstop work in research production at temperatures from -10 to 40°C. Thanks to its extremely compact construction and small footprint, it fits anywhere. It is used where operating heat has to be discharged reliably and quickly in chemical production processes or from technical systems in harsh, constant use environments. Unlike cooling with tap water, this chilling circulator provides a constant temperature irrespective of the time of year and pressure fluctuations. The independent cooling-water system instead of a central cooling-water supply avoids the leakage of substances that are hazardous to the environment. The water savings also protects the environment and significantly reduces operating costs.
The WKL 230 was especially designed for simple thermostating tasks below 0°C. Thanks to its extremely compact construction and small footprint, it fits anywhere. It has an LED display and a 3-button operation, and features a submersible pump that eliminates seal problems at the pump shaft. Standard accessories include a bath cover, nipples, and screw caps. Applications include rotary evaporators and Soxhlet systems, analytical devices such as electron microscopes, X-ray units, refractometers, distilling systems, X-ray control systems such as at airports and semiconductor systems, control of cooling traps such as in the drying of gasses, and central cooling water supplies for complete laboratories to replace cooling with tap water.
