RECOIL is the answer to the easy cleaning of refrigeration and compressor vanes in air conditioning units and heat exchangers. The high-density foam generated by RECOIL is ideal for allowing extended working time in those hard-to-reach areas. The components in RECOIL were blended to attack the oil-laden dust build -up which is common to refrigeration and heat exchanger coils. This dust build-up acts as an insulator, reducing efficiency and causing heat build-up as well as increasing power usage . RECOIL quickly penetrates and lifts these soils allowing a cooler, more efficient operation of compressors, exchangers and cooling systems. The "user friendly" characteristic of RECOIL enables the skilled technician as well as the general maintenance person to attack a normally time-consuming task with rapid, efficient results.
