Synthetic Refrigerant Additive (SRA)

This is a liquid that is added to the refrigeration circuit of an air conditioning system, chiller, cooler, or freezer. It improves the efficiency of the system by about 15%. Power Knot guarantees that it will improve the efficiency by at least 10%. (The SRA is also referred to as the Synthetic Refrigerant Catalyst.)

SRA is compatible with most air conditioning or refrigeration systems and most refrigerants. It is easily applied and is a safe and effective way to easily reduce your carbon footprint and save money.

Liquid Food Composter (LFC)

Why waste money to have your food waste hauled to the landfill? Why destroy the planet as that food waste decomposes into methane, a gas that is 70 times as bad as CO2?

The answer is to decompose on site and this product will do that for you. It's simple, safe, sanitary, and cost effective.

Vortex Condenser Controller (VCC)


The VCC is a mechanical device installed in the refrigerant line of an existing air-conditioner or refrigeration system. All VCC models achieve over 15% energy saving on air-cooled systems and over 5% energy savings on water-cooled systems.

The VCC is designed with quality, reliability, and longevity in mind. With no moving parts, other than a single float ball to indicate the flow of the refrigerant, there is nothing to break or wear out. In addition, the VCC does not require water, electricity or any additional source of energy to improve the efficiency of air conditioning or cooling systems.

Intelligent Motor Controller (IMC)


The IMC from Power Knot provides dynamic control of a motor across a wide range of applications and conditions.

A standard electrical motor becomes less efficient on loads other than full load. The excess power is costly and turns to heat. The heat damages the motor and is the major cause of motor failure.

The IMC constantly monitors the motor’s load and dynamically adjusts the power to the motor so that it consumes the correct amount of power to match the actual load on the motor. This reduces the amount of electricity used, increases the life of the motor, reduces maintenance requirements, eliminates heat, and saves money.
