Specification Brand : ZeroR BulletPoint1 : NOT A Full Refrigerant - This product is a support fluid performance booster. It is a combination of two ZeroR products in one. The first part removes moisture (moisture can cause damage and reduced performance in the system), and the second part reduces friction (friction can reduce refrigerant flow and cause compressor damage) BulletPoint2 : Designed to Enhance and Extend New and Old Systems BulletPoint3 : ZeroR Permafrost contains a highly polar molecule that works synergistically with compressor oil to improve the performance of air conditioning and refrigeration systems by increasing heat transfer in the condenser and evaporator coils. BulletPoint4 : ZeroR Permafrost polarized molecule bonds to the metal inside system by removing the insulated buildup of oil and forming a conductive layer to improve heat transfer. BulletPoint5 : Returns: This item is considered a HazMat Material and as such is not returnable. It requires hazmat certification to ship. Amazon does not supply a Return label and the seller will not supply return labels for this type of products. Please contact seller for any help you might need in using the product.
