DescriptionThe Power Knot SRA Synthetic Refrigeration Additive is a liquid that is added to the refrigerant of an existing air-conditioner or refrigeration system. SRA achieves over 15% energy saving on air-cooled and over 10% energy savings on water-cooled systems. Power Knot supplies the correct amount of fluid for small to very large systems. SRA works on all common refrigerants including R-22 and R-410A.

After you add SRA, you will immediately start to save energy, or for the same energy, you will have greater cooling. As a synthetic component, SRA causes no damage to the cooling system but on the contrary, it extends the life of the system and thereby reduces maintenance.

SRA is applicable for residential, commercial, industrial, auto-motive, and haulage applications.

Energy SavingsSRA will deliver efficiency gains of 15% to 25%. If the cooling unit already has sufficient cooling capacity, then SRA will deliver electricity savings.

If the cooling unit does not have sufficient cooling capacity, SRA will increase the cooling capacity of the system by 15% to 25%.

With SRA, heat pump systems will save energy in winter heating mode as well as summer cooling mode.

Power Knot guarantees that SRA will deliver at least 10% ef-ficiency gains on your system.

InstallationSRA is added in the refrigerant line of the existing cooling system or heat pump. You do not drain down the refrigerant in the system and you do not need to turn off the system. This installation requires a certified HVAC technician, and takes several minutes.

If you have several cooling units, a technician can complete the installation of SRA in many units in a day.

How it worksSRA is a synthetic blend of two components that work together to improve the cooling system. The first compo-nent removes oil fouling on the walls of the evaporator and compressor pipes. This improves heat transfer in these pipes by over 70% and delivers colder air to the ventilation.

The second component delivers greater lubricity to the com-pressor oil. This allows the compressor to use less power and run cooler,. This thereby increases the life of the compressor.

The result is that you typically obtain at least 20% savings in energy, at least 20% reduced maintenance costs, and at least 20% extension of the life of the compressor.

Energy EfficiencyEnergy efficiency is perhaps the most important technol-ogy businesses can use to reduce operating expenses and reduce greenhouse gas emissions. The USA Energy Infor-mation Administration states that HVAC and refrigeration systems consume over 24% of all electricity in the United States each year.

Efficiency of cooling systems represents a major opportunity for businesses to reduce costs.

Global FeaturesPower Knot sells and supports its products worldwide. The SRA refrigeration additive is compatible with most cooling and heating units in every country so it can save money

globally.

Specifications

Properties

SRA is a proprietary synthetic formulation that does not chemically ■alter the refrigerant or the oil.
