Does your air conditioner no longer cool the same as when purchasing? COOL-SHOT ULTRA is an additive that restores the original efficiency of automotive air conditioners as well as residential, commercial and industrial air conditioning and refrigeration systems. By eliminating oil spills, i.e. oil deposits that accumulate on the walls of the cooling lines, the original heat exchange of refrigeration and air conditioning systems is restored and energy consumption is reduced, resulting in significant cost savings. COOL-SHOT ULTRA also increases the effectiveness of the compressor lubricant. It is compatible with all lubricants and cooling gases, including R12, R134a, R1234yf, CFC, HFC, HCFC including R32 and HFO (with the exception of ammonia R717). It is compatible with hybrid and electric vehicles. Only 6 ml COOL-SHOT ULTRA (one syringe) is enough to restore the original performance of a vehicle's air conditioning or air conditioning systems up to 21 kW (or 700 ml compressor lubricant). Used in preventive applications, it avoids the formation of oil spills and maintains the efficiency of the system over a longer period of time. Visible when exposed to UV light. The package contains all necessary adapters for inserting the additive into air conditioning and cooling systems, including motor vehicles: - Adapter with R134a (black). - Flexible hose for easy connection to the system. The adapters can be reused. For more information on errecom.com.
