Commercial cooling
For office rooftop units and chillers, the aim is to remove oil fouling and restore heat transfer.

A technology of IceCOLD Technology, LLC
IceCOLD is a synthetic catalyst the removes oil fouling, restores lost efficiencies, and extends equipment life of your HVAC systems. Compatible with most refrigerants, it reduces compressor run times and lowers energy consumption.
The problem
What is oil fouling?
Video claims are the publisher’s.
Watch on YouTube (opens in a new tab)Oil fouling is the film of compressor oil that builds up on internal heat-transfer surfaces, making it harder for the system to move heat.
Equipment and refrigerant compatibility must be confirmed with the manufacturer before application.
Three-part mechanism
Strips the fouling.
The first catalyst strips the oil fouling and restores the heat transfer surface.
Lowers evaporation temperature.
The second lowers the refrigerant evaporation temperature, so the system delivers colder supply air and reaches setpoint sooner.
Improves lubricity.
An advanced lubricity agent helps the compressor run more smoothly.
Where the saving comes from, stated plainly
IceCOLD does not reduce the amp draw of the compressor motor. The compressor pulls the same current when it is running. The saving comes from the compressor running less, because the system reaches setpoint faster and holds it. Shorter run times mean lower consumption, less wear, fewer service calls and longer compressor life.
A catalyst, not an additive
A catalyst causes a reaction by being present and is not consumed or changed by it. It does not need topping up, and it does not alter the refrigerant.

Applications
Where it applies
Food retail and hospitality
For refrigeration racks, walk-in freezers and reach-in coolers, the aim is the same: remove oil fouling, restore heat transfer.
Equipment and refrigerant fit must be confirmed with the manufacturer before application.

Before you specify it
What it works on, and what it does not.
The questions a contractor or facilities manager asks first.
- Systems
- Potential applications include commercial HVAC and refrigeration systems such as rooftop units, chillers, refrigeration racks, walk-in freezers, reach-in coolers, salad bars and food prep tables. Suitability depends on the equipment and refrigerant and must be confirmed with the manufacturer before application.
- Refrigerants
- Refrigerant compatibility and the appropriate IceCOLD formulation must be confirmed with the manufacturer before application, including for ammonia systems.
- Safety
- No health or safety risk, and no toxic or carcinogenic content, per IceCOLD Technology.
- Downtime
- Applied to equipment already in service, with no replacement and no extended shutdown. Confirm the per-unit application window with Cool Estate for your equipment type.
- Best economics
- Large, long-running cooling and refrigeration loads. Grocery, retail chains and quick-service food are where the documented evidence is strongest.
- Also a strong fit
- Hotels, multi-family, long-term care, campuses and central plant, and data centres.
Start with one unit
Your result, not a case study from somewhere else.
We measure a baseline before application, then measure again. Cool Estate can set that up on a single unit first, so the evidence is from your own equipment.

The questions buyers ask first.
How does IceCOLD save energy?
IceCOLD removes oil fouling to restore heat-transfer efficiency in existing HVAC and refrigeration systems. Improved heat transfer can shorten compressor run times rather than reduce current while running. Results depend on the equipment and operating conditions.
Who distributes IceCOLD in Canada?
Cool Estate represents IceCOLD in Canada and can assess a site and quote the saving.
Does IceCOLD reduce my compressor's amp draw?
No, and it is worth being clear about that. The compressor draws the same current while running. The savings come from it running fewer hours, because the system reaches setpoint faster and holds it.
Which refrigerants does IceCOLD work with?
Refrigerant compatibility and the appropriate IceCOLD formulation must be confirmed with the manufacturer before application, including for ammonia systems. Ask Cool Estate to review your equipment and refrigerant.
Is it an additive?
No. It is a catalyst, which means it causes a reaction by being present without being consumed or changed by it. It does not alter the refrigerant and does not need topping up.
How are the savings proven?
Against a measured baseline taken before application. Cool Estate can set that up on a single unit first, so the result is yours rather than a case study from somewhere else.
