25 YEARS OF ENERGY SAVINGS LUBRICATION ENHANCEMENT SYSTEM

MAIN BENEFITS CONSERVES energy REDUCES friction of moving compressor parts during operation as well as start-up. QUIETS the decibel level during operation. PROVIDES relief from service issues. RESTORES heat exchange by eliminating oil fouling. SAVES time and money spent on repairs and downtime with payback times almost always less than 24 months. maintenance

REFRIGERATION CYCLE We'll begin with the cool, liquid refrigerant entering the indoor coil, operating as the evaporator during cooling. As its name implies, refrigerant in the evaporator "evaporates." Upon entering the evaporator, the liquid refrigerant's temperature is between 40 and 50°F and without changing its temperature; it absorbs heat as it changes state from a liquid to a vapor. The heat comes from the warm, moist room air blown across the evaporator coil. As it passes over the cool coil, it gives up some of its heat and moisture may condense from it. The cooler, drier room air is re-circulated by a blower into the space to be cooled. The vapor refrigerant now moves into the compressor, which is basically a pump that raises the pressure so it will move through the system. Once it passes through the compressor, the refrigerant is said to be on the "high" side of the system. Like anything that is put under pressure, the increased pressure from the compressor causes the temperature of the refrigerant to rise. As it leaves the compressor, the refrigerant is a hot vapor, roughly 120 to 140°F. It now flows into the refrigerant-to-water heat exchanger, operating as the condenser during cooling. Again, as the name suggests, the refrigerant condenses here. As it condenses, it gives up heat to the loop, which is circulated by a pump. The loop water is able to pick up heat from the coils because it is still cooler than the 120-degree coils. As the refrigerant leaves the condenser, it is cooler, but still under pressure provided by the compressor. It then reaches the expansion valve. The expansion valve allows the high-pressure refrigerant to "flash" through becoming a lower pressure, cooled liquid. When pressure is reduced, as with spraying an aerosol can or a fire extinguisher, it cools. The cycle is complete as the cool, liquid refrigerant re-enters the evaporator to pick up room heat

How Frigi-Tech Works Frigi-Tech’s polarized molecules bond to the metal inside the system, preventing the insulating build-up of oil which occurs over time due to oil fouling. Frigi-Tech will cause the insulating layer of oil to return to the compressor where it belongs and no longer builds up on heat transfer surfaces.

Frigi-Tech will restore the efficiency in the condenser and evaporator coils by restoring the heat exchange.

Treatment Times Frigi-Tech is a one-time treatment. The only time additional Frigi-Tech is required is if and when a compressor is replaced or an oil change on a chiller. maintenance

FEATURES &BENEFITS FEATURES BENEFITS Increased heat transfer in the evaporator and condenser up to 25% Improved cooling with shorter cycle times, equating to less run time and energy used Reduction of friction Lower amp draw and reduced start amps Reduced noise and vibration Comfort of the mechanical rooms Lower operating temperatures of the oil and the compressor For every 10 degrees Celsius a motor runs hotter, it reduces its life by 50% Improved energy efficiency Payback time realized in months and then all further savings go towards the bottom line.

TYPICAL BEARING WEAR Worn roller bearing magnified 1000x. This is a photograph of a worn bearing magnetized a 1000 times

CONDITIONED BEARING AFTER Frigi-Tech Same bearing after Frigi-Tech was added. Metal surfaces become polished smooth to aid in friction reduction. This is the same bearing showing how Frigi-Tech conditioned the metal surfaces. This demonstrates how Frigi-Tech will reduce noise and vibration as well as reduce friction.

This is the first slide of three test performed in a laboratory This is the first slide of three test performed in a laboratory. This test represents the breaking force. We applied pressure to see at what point the lubrication broke down and caused the motor to lock up.

In this test we are applying the same amount of pressure with the same amount of time to measure the bearing wear in inches. This is where we have the ability to say that we should double the remaining life of the compressor at the time Frigi-Tech is installed.

What this slide represents is the #1 enemy to an HVAC&R system, moisture. Moisture creates oxidation creating hydrochloric and hydroflouric acid. You can see when Frigi-Tech was introduced we show 3 times the oxidation and corrosion protection over the standard refrigerant oil. This won’t save you on energy but will save you on maintenance issues.

DO WE VOID MANUFACTURER’S WARRANTY ? FRIGI-TECH MEETS AND THEN EXCEEDS After the introduction of Frigi-Tech there was a 1,500% improvement in the mixture lubricating ability. The modified Falex test was used to determine lubricity. Frigi-Tech exceeded the 582 pound limits of the test.
