Reftec has recently been certified by the American Bureau of Shipping (ABS).  Our products are being utilized in the cruise industry, naval applications as well as onboard tankers and freight liners.  Please contact us for your ocean going vessel HVAC needs. 


“As a service provider in the HVAC and Commercial Recovery Recycling Equipment repair industry for over 19 years, we realize the value of quality designed and well built equipment. Time is money and most recovery recycling equipment is built with the smaller systems in mind, primarily having portability be the prerequisite to build. Reftec has always been ahead of the curve with equipment designs that almost double the recovery rates of competitive units of there class with very little sacrifice in weight. A few pounds in weight is well worth the hours saved on a rooftop or chiller job.”

  • Microprocessor Controls Prevent Catastrophic Refrigerant Loss Due to:
    • Low chiller condenser saturation temperature
    • Purge vessel liquid overflow or return line restriction
    • Excessive purge pumpout time
    • Condensing unit malfunction
