The MRC Series thermoelectric recirculating liquid chiller is a self-contained device that controls the temperature of a coolant in a liquid circuit.

The MRC Series thermoelectric recirculating liquid chiller is a self-contained device that controls the temperature of a coolant in a liquid circuit. Features include a universal input voltage of 115 to 230 VAC, UL certification, RoHS compliance, solid-state construction and no CFC refrigerants. Both heating and nonheating configurations are offered. These chillers dissipate the heat generated from laser systems by keeping the optics at a stable temperature.

Laird Technologies Introduces Enhanced MRC Series Thermoelectric Recirculating Chiller

Highly Reliable Thermoelectric Liquid Chiller Improves Performance of Semiconductor and Medical Applications

St. Louis, Missouri, USA – October 28, 2010 – Laird Technologies, Inc., a global leader in the design and supply of customized performance-critical components and systems for advanced electronics and wireless products, today announced the release of its enhanced MRC Series Thermoelectric Recirculating Liquid Chiller.

MRC Series Thermoelectric Recirculating Liquid Chiller is a self contained device that offers dependable, compact performance by controlling the temperature of a coolant in a liquid circuit. The coolant is recirculated using a brand name pump with high mean time between failures (MTBF). Heat from the coolant is absorbed by a heat exchanger and dissipated through high-density heat sinks equipped with premium fans. The heat pumping action occurs from custom designed Thermoelectric Modules (TEMs) in order to achieve long life operation. The unit is regulated with an easy-to-use digital temperature controller and is housed inside an aesthetic sheet metal casing. The unit operates on a universal input voltage of 115 to 230 VAC, and is UL certified and RoHS compliant. Products in this series are offered in two configurations:

  • Heating – MRC150,DH2,HT,DV and MRC300,DH2,HT,DV
  • Non-heating – MRC150,DH2,DV and MRC300,DH2,DV

“Feedback from customers was to develop a chiller that could run continuously 24 hours a day, seven days a week. Extensive research into the reliability of primary and secondary components was conducted, and Validation Testing confirmed improvements could be achieved in five component areas,” said Andrew Dereka, Laird Technologies Thermoelectric Product Manager. “The enhancements were implemented more than a year ago, and feedback from the field has been extremely positive.”

Key benefits include compact size, solid-state construction, and environmental friendliness. In cooling capacity requirements below 400 Watts, there is a considerable size and weight advantage over conventional compressor-based systems. There are no CFC refrigerants, so the design contains less moving parts, requires less maintenance, and does not harm the environment. This makes the product ideal for integrating into laser or imaging systems that have tight geometric space constraints and weight limit requirements.

The MRC Chillers dissipate the heat generated from laser systems by keeping the optics at a stable temperature so they operate at peak performance. They provide optimal temperature stabilization in applications such as DPSS laser systems for precision cutting in high tech manufacturing processes and semiconductor wafer cutting. They are also applied in medical applications such as CO2 and YAG laser systems for cutting human tissue in cosmetic treatments, and for maintaining the temperature of imaging detector heads used in capturing high resolution images of patients.

As an industry leader in high-performance and cost-effective Thermal Management Solutions, Laird Technologies provides the knowledge, innovation, and resources to ensure exceptional thermal performance and customer satisfaction for applications in the medical, analytical, telecom, industrial, and consumer markets.
