Modular Refrigeration Unit (MRU)


Modular Refrigeration Unit (MRU) provides thermal control to insulated containers in ambient temperatures as high as 130°F and as low as -40°F. Both the MRU-TQ1-404 and MRU-TQ3-404 can be rigidly attached to either the Tricon or Quadcon insulated containers. The MRU is designed to replace the Thermo King VM405 and the Carrier Integra 30S with improved performance, reliability, and ease of maintenance. Using a high-efficiency, environmentally safe refrigerant, the MRU meets or exceeds all requirements for military container heating and cooling.
