Boost performance and protect your A/C system

Errecom's Cool Shot Ultra is a 6 mL synthetic catalyst that helps prevent and repair efficiency loss in air conditioning and refrigeration systems. It’s the smart choice to prevent oil fouling or restore system performance after years of use.

How it works

This dual-action formula dissolves oil buildup inside the system and carries it back to the compressor. It enhances lubricant effectiveness, reduces noise, and cuts down on energy use—without altering refrigerant properties.

Ideal for all AC/R systems

Cool Shot Ultra is safe for all gases, including R410a, R32, and CO2. Whether you're working on a domestic split system, commercial refrigeration, or vehicle A/C, it helps protect and prolong the life of your setup.
