refrigerant enhancer by yellowblue.
bluemaxx™ is a synthetically engineered liquid which is added to the refrigerant of an air-conditioner or refrigeration system. It seeks out oil fouling in an existing system to eliminate or help reduce it from building up over time. By eliminating the oil fouling, the increased performance of your system can be attained. Once the bluemaxx™ liquid is in the system, you should start feeling the difference. It also, should provide greater cooling for the same amount of energy. As a synthetic component, bluemaxx™ is guaranteed to cause no damage to the cooling system (call for details).
