Supplied in a 4 oz bottle, this additive is designed to maintain proper lubrication and flow characteristics within the TXV and refrigerant circuit. It is factory-approved, meaning it meets the performance and chemical compatibility standards required for use in systems where it is specified. Licensed HVAC technicians handling refrigerant-side service work are the primary installers of this product.
This additive is applied during refrigerant system service on residential and light commercial HVAC equipment that uses TXV metering devices. It is particularly relevant during compressor replacement, refrigerant retrofit, or TXV servicing where maintaining proper lubrication within the metering device is a service requirement. Application is limited to systems and scenarios where a factory-approved TXV additive is specified by the equipment manufacturer.
Designed as a factory-approved TXV additive for HVAC refrigerant systems where Zerol Ice treatment is specified by the equipment manufacturer.
Installation should be performed by a licensed HVAC technician certified to handle refrigerants under applicable EPA Section 608 regulations. Recover refrigerant and relieve system pressure before opening any refrigerant circuit connections. Follow the equipment manufacturer's service documentation for the correct additive injection procedure and quantity. Do not mix with additives or lubricants not specified for the system.
