Peak PXA003 Extended Life Premixed Antifreeze 1 Gal

Product Description

The PEAK PXA003 is a premixed extended-life antifreeze and coolant formulated with ethylene glycol and an organic acid inhibitor (OAT) system. It comes ready to use at a pre-diluted concentration, eliminating the need to blend with water on the job. The organic acid inhibitor package provides long-interval corrosion protection for metal and alloy surfaces inside cooling systems, including aluminum, cast iron, and steel components. HVAC technicians and mechanical contractors use this product when servicing hydronic heating systems, chiller circuits, closed-loop cooling loops, and engine-driven equipment where freeze and boil-over protection is required.

The PXA003 is suited for residential and light commercial applications where a pre-diluted, extended-life coolant is specified. Typical install scenarios include closed hydronic loops, fan coil unit piping, fluid coolers, and equipment cooling jackets. The 1-gallon container is practical for small system top-offs, initial fills on compact circuits, or keeping on a service vehicle for field use. It is appropriate wherever an ethylene glycol OAT coolant meets the equipment manufacturer's fluid specification.

Key Features

• Premixed formula requires no dilution before use
• Ethylene glycol base delivers freeze protection and elevated boiling-point protection
• Organic acid inhibitor (OAT) chemistry provides extended corrosion protection for mixed-metal systems
• 1-gallon container size is field-service friendly for top-offs and small fills
• Ready-to-install convenience reduces mixing errors on the job

Compatibility

Designed for use in closed-loop hydronic and equipment cooling circuits requiring a premixed ethylene glycol OAT antifreeze and coolant. Verify compatibility with the equipment manufacturer's fluid specification before use.

Installation Notes

A licensed HVAC technician or mechanical contractor should perform coolant service on closed hydronic and refrigeration-adjacent systems. Always depressurize and isolate the circuit before opening any fill ports or drain valves. Dispose of used coolant in accordance with local environmental regulations, as ethylene glycol-based fluids require proper handling. Do not mix with incompatible coolant chemistries without flushing the system first.
