TIF was originally formed in Miami, FL in the 1950's under the name Thermal Industries of Florida, Inc., and was an outcropping of Miami's then largest HVAC/R contractor. In 1960 the company name was formally changed to TIF Instruments, Inc. and the new independent business was founded upon the concept of bringing new and innovative service test instruments to the trade. Over the past 40+ years TIF grew through the support of professional technicians worldwide and has become the recognized leader in both electronic refrigerant leak detection and refrigerant measuring devices.
Promax products consist of refrigerant recovery machines.
Promax was founded in 1990 just as the Clean Air Act and refrigerant containment were becoming industry news and affecting the way Air Conditioning and Refrigeration systems would be serviced for evermore. The goal of the company was to provide an efficient and reliable product for technicians to recover refrigerant in the field under the harshest and most extreme conditions. Promax's claim to fame and success since inception is almost entirely due to its revolutionary and proprietary "Oil-Less" refrigerant compressor. Oil-less recovery offers a number of performance advantages over competitive systems, and the Promax compressor is known world-wide as the pinnacle of the principle in action.
