What is “PermaFrost”
• A super thermal-conductive additive
used to improve the efficiency of chillers
and refrigeration equipment
• Developed and manufactured in U.S.A.
(4 patents between 1990s and 2002)

How it works (1)
Lubricating oil contaminated the evaporator & condenser!
POWER CONTROL LIMITED
Before PermaFrost
Reduced heat transfer
Tubing Wall
Stagnant Oil
Excessive
Laminar friction
Tubing Wall
Energy loss
Stagnant Oil
This barrier reduces the heat transfer inside the refrigerant circuit and increases the
energy consumption (kWh).
POWER CONTROL LIMITED
After PermaFrost (1)
Accelerated Heat Transfer
PermaFrost Thermoconductive molecules
Reduced laminar friction
Stagnant oil dispersal
Refrigerant contacts metal
PermaFrost molecules are attracted to the inner metal tubing. The thermo-conductivity
rate is ACCELERATED and laminar friction is virtually eliminated.
POWER CONTROL LIMITED
After PermaFrost (2)
Accelerated Thermo Conductivity.
Stagnant Oil cleared
Efficient turbulent
flow
Refrigerant
PermaFrost Thermoconductive molecules
Faster Heat Dispersal
Oil barrier is completely and permanently removed
POWER CONTROL LIMITED
After Applying PermaFrost
• The insulative oil barrier is completely and
permanently removed.
• The inner metal surface is bound by thermoconductive PermaFrost molecules.
• Heat transfer between the refrigerant and chilled water
/ air will speed up.
• The compressor will run a shorter time in producing
the same cooling capacity.

Advantages of “PermaFrost”
• Saves over 10% in electricity consumed
by chillers
Reduce Energy !!
Save Money !!
Increase Profits !!
POWER CONTROL LIMITED
Advantages of “PermaFrost”
• Easy to install
– just manually pump into the existing lub oil
• Zero down time
• No mechanical modification
• Extends equipment (compressors) life
POWER CONTROL LIMITED
Suitable Application
PermaFrost may be used in most air-conditioning
and refrigeration systems with the exception of
absorption chillers.
Systems where PermaFrost can be used are as follows:
Reciprocating Compressor
Centrifugal Compressor
And many other refrigeration systems…
Screw Compressor
Scroll Compressor

Performance Evaluation
• The efficiency of a chiller is defined by the
coefficient of performance (COP)

Example
Savings Due to PermaFrost for a 100 Ton Chiller
Cooling Capacity = 100 Ton = 352 KW (a)
COP = 2.8 (b)
Power Input = (a) / (b) = 126KW at full load
Diversity = 0.7
Hours of Operation Per Day = 16 hours
Yearly Electricity Consumption
= 126 KW X 16 hours X 0.7 X 365 days X $1.26 / KWH
= ~ HK$650,000
• For a savings of 10% after treatment of “PermaFrost”
Total Amount of Savings
~ HK$65,000 per year
