The MRC series from Laird Engineered Thermal Solutions is a bench top re-circulating chiller that offers dependable, compact performance by controlling the temperature of a coolant in a liquid circuit. The coolant is re-circulated using a pump with high MTBF. Heat from coolant is absorbed by a heat exchanger and dissipated through high-density heat-sinks equipped with brand name fans. The thermoelectric modules are custom designed to achieve long-life operation. The unit is regulated with an easy-to-use digital temperature controller with push button interface. The controller can control the temperature of a liquid circuit at outlet from -12°C to 40°C. The unit operates on 115 or 230 VAC and is UL/IEC rated.
