MRP Recirculator Systems


MRP Recirculator Systems are completely assembled by a factory-trained workforce dedicated to building quality refrigeration products.  All packages, vessels and piping are fabricated from ASME Code materials by certified welders.  The packages are assembled in a controlled factory environment to the industry’s highest quality standards.  The finished package is designed for long-life, simplified installation, and easy access to perform routine maintenance functions


The new MRP Recirculator System utilizes the highest quality and most advanced components available in the refrigeration industry today.  At the heart of the MRP Recirculator System is the Matrix Microprocessor Panel. The Matrix Microprocessor Panel has been engineered to provide total recirculator control including proportional liquid feed and level control, pump

protection and a state of the art by-pass flow control (patent pending) to improve pump efficiency and capacity.  The standard MRP Recirculator System features Teikoku hermetic pumps with exclusive bearing wear monitor and secondary containment system to eliminate the possibility of a refrigerant release.  The MRP Recirculator System is available in a complete range of

vessel diameters from 24” to 144”, in both vertical and horizontal



Matrix Microprocessor Panel

The RVS Matrix Microprocessor Panel utilizes the latest technology to provide a total control solution for the MRP Recirculator System.  The Matrix Panel features a NEMA-4 enclosure and is UL/cUL listed.  The standard MRP Recirculator incorporates a Matrix Microprocessor Panel with starters, disconnects and power transformer requiring only a single power

connection in the field.  Factory packaging assures a completely tested andfunctional unit, ready-to-go without expensive field wiring and complicatedPLC programming, for simplified installation and start-up.
