System SummaryUser Manual
1. Introduction
System Summary
The Polcold® P-102 Portable Cryocooler provides compact, portable, and easy-to use alternatives to
liquid nitrogen used in small vacuum systems. These cryogenerators use refrigerants in a closed loop
system. The refrigerants are:
l Safe
l Non-flammable
l Non-toxic
l HCFC-free
This means there is no moving of heavy liquid nitrogen dewars. Also, there is no running out of
cryogen causing downtime.
Installation is quick and easy. Either a cold probe is inserted into a housing or a chevron baffle is
installed between a diffusion pump and a high vacuum valve. The cold probes and chevron baffles are
referred to as cryosurfaces. These are part of the refrigerant line. Removing them causes a loss of
refrigerant.
Cold trapping applications include:
l Helium mass spectrometer leakdetectors
l Chevron baffles for diffusion pumps up to 6 inches (160 mm) in diameter
l Vapor trapping cold probes that protect mechanical pumps on smallvacuum systems.
Basic Principles of Operating for the Polycold Refrigeration Cycle
This cooling process is an auto cascade refrigeration system. A patented mixture of non-flammable
and safe CFC-free and HCFC-free refrigerants is compressed and circulated by a compressor. In a
simplified version, the Polycold refrigeration cycle comprises:
1. Compressing a mixture of refrigerants
2. Partially condensing the higher boiling fractions in an air-cooled condenser
1-1Brooks Automation
Page 9
1. Introduction
User ManualBasic Principles of Operating for the Polycold Refrigeration Cycle
3. Separating and throttling the liquid condensate produces cooling that condenses the remaining
vapors in a special heat exchanger. In the process of providing cooling in the Cryocooler, this
mixture is partially evaporated.
4. Throttling this latter condensate and feeding the cryocoil to produce cooling at very low
temperatures
5. Passing the refrigerant leaving the cooling coil back through the heat exchanger to the compressor.
Operating pressures and compressor temperatures are similar to those in air-conditioning systems.
The compressor lubricating oil circulates with the discharge vapors. The oil promptly returns to the
compressor without reaching the very low temperature portions of the system. This eliminates the
common problems of oil plugging in evaporators and expansion devices too often seen in low
temperature systems.
The mixed refrigerant charge is hermetically sealed into the system. Normally neither the refrigerant
nor the compressor lubricating oil requires replacement or recharging.
In this unit, there is a series of intermediate special heat exchangers called cascade condensers.
These are located between the air-cooled condenser and the final cooling coil (cold probe). There are
multiple stages of partial condensation, phase separation, condensate throttling, and intermediate
cooling. In addition, the system has a suction-side refrigerant vapor expansion tank and a dischargeside receive tank to limit start-up discharge pressures.

CAUTION
Tip Hazard
Tip hazard exists when moving the P-102 up or down a ramp.
Be sure to prevent the P-102 from tipping when using a ramp.
2. Roll the P-102 carefully to where the tool is to be installed. Be sure the floor is smooth and there is
no tip hazard. Roll the P-102 very carefully if it must roll up or down a ramp. This may cause a tip
hazard.
3. The system may be operating continuously. It should be turned off any time the fore- or roughing
pump(s) are to be turned off.
Starting Up the P-102
1. Start the unit by turning on the front panel switch.
l You can hear the compressor and condenser fans start running.
l The Power light on the front panel lights.
l Within about 5-10 minutes, cooling begins in the cold probe.
If the compressor turns off during initial start up, turn the switch off for 5-10 minutes, then turn the
switch on again to restart the P-102.
Do not operate the unit for more than 15 minutes. This causes moisture to accumulate on the cold
probe.
2. Turn off the unit.
3. Warm the cold probe.
4. Dry the cold probe.
5. Inspect all vacuum sealing surfaces where the cold probe or cryobaffle is to be used. The surfaces
must be clean and free from scratches or other imperfections that might result in vacuum leaks.

Defrosting the P-102User Manual
The system may be operating continuously. It should be turned off any time the fore- or roughing pump
(s) are to be turned off.
Defrosting the P-102
If vacuum pump-down times or ultimate levels degrade, the cold probe may have accumulated enough
frost to affect performance.
1. Close the high vacuum valve and turn off the Cryocooler P-102 unit. The diffusion pump may be left
on or turned off at the user’s option.
2. Leave the fore-pump on to remove the evaporating moisture from the system.
Overnight defrosting is suggested. After defrosting, the P-102 unit can then be turned on again.
Restart the diffusion pump if it also was turned off. Many applications have low moisture loads and
continuous operation for months is possible without defrosting. Those systems with very heavy
moisture loads may require weekly defrosting.
Compressor and Condenser Fan Motors
The compressor and condenser fan motors are lifetime lubricated and do not require regular oiling.
Both the compressor and condenser have temperature switches that turn off either the fan or the
compressor if the motors for either begin to overheat.
Safe Shut Down
The following shut-down procedure is used to remove power from the Cryocooler P-102.
NOTICE
This shut-down procedure is used in the normal shut-down of the Product. This
procedure completely removes the power source and all other facilities to the
product.
1. Turn off the facility power to the P-102 or unplug it from the disconnect.
2. Turn off the ON/OFF switch. The light on the switch turns off.
3. Observe that the sounds of the fan, and condenser stop.
