DescriptionDescription

Description The CryoCool Series of immersion coolers is designed as a refrigeration

source for sub-ambient work in liquid baths.

CryoCools employ mechanical refrigeration systems constructed with full-

hermetic refrigeration compressors. The CC-65 employs a single stage

refrigeration system with one compressor. The CC-100 has a dual stage

refrigeration system using two compressors in cascade configuration. An

insulated coaxial hose assembly carries refrigerant to the cooling probe.

Section III Installation

SiteSite

Site The unit should be located in a laboratory or clean industrial environment

where ambient temperatures are inside the range of +55°F to +95°F (+13°C

to +35°C).

Never place the unit in a location where excessive heat, moisture, orNever place the unit in a location where excessive heat, moisture, or

corrosive materials are present.

The unit has an air-cooled refrigeration system. On the CC-65 air is drawn

through the top of the unit and discharged through the sides and bottom of

the unit. On the CC-100 air is drawn through the front of the unit and dis-

charged through the rear. The unit must be positioned so the intake and

discharge are not impeded. A minimum clearance of 12 inches (30 centi-

meters) on all vented sides is necessary for adequate ventilation.

Inadequate ventilation will cause a reduction in cooling capacity and, in

extreme cases, compressor failure.

Excessively dusty areas should be avoided and a periodic cleaning schedule

should be instituted (see Section V, Cleaning).

The unit will retain its full rated capacity in ambient temperatures up to

approximately +75°F (+24°C). Above +75°F, reduce the cooling capacity 1%

for every 1°F above +75°F, up to a maximum ambient temperature of +95°F.

In terms of Celsius, reduce the cooling capacity 1% for every 0.5°C above

+24°C, up to a maximum ambient temperature of +35°C.

Never use flammable or corrosive fluids with this unit.

Cooling ProbesCooling Probes

Cooling Probes Three cooling probes (or evaporator heads) are available with CryoCool

units: F (flexible), FV (flexible, very), and R (rigid). Refer to Section II,

Specifications to determine the specific cooling probe on your unit.

Place the cooling probe in the work area. For maximum cooling efficiency,

the probe should be fully immersed in the fluid and should be located as

close as possible to the agitator or stirrer motor (if so equipped).

Care should be taken not to stretch or bend the probe beyond it limitsCare should be taken not to stretch or bend the probe beyond it limits

Section IV OperationSection IV Operation

Section IV Operation

OperationOperation

Operation Before starting the unit, double check all electrical connections and make

sure the cooling probe is properly immersed in the work area.

All CryoCools are operated by a single power switch.

The CC-100 has three lights: one indicates the unit is operating, a second

indicates the high stage compressor is operating, and a third indicates the

low stage compressor is operating.

Once the unit is turned on, the refrigeration system will reduce the tempera-

ture of the cooling fluid in the work area to the lowest achievable temperature

under the existing heat load conditions.

For best results, stirring or agitation in the work area is recommended.

When not stirred, cooling capacities will be reduced and the work area will

show temperature layering, with the coldest, most dense zone at the bottom.

When the unit is shut off, wait approximately five minutes before restarting.

This allows time for the refrigeration pressures to equalize. If the pressures

are not allowed to equalize, the compressor will short-cycle (clicking sound)

and no cooling will occur.

TemperatureTemperature

Temperature

AdjustmentAdjustment

Adjustment If temperature control is desired, a Thermo NESLAB Cryotrol Temperature

Controller is required. Refer to the Cryotrol Temperature Controller Instruc-

tion and Operation Manual for installation and operation instructions.

Never operate any CryoCool unit above -25°C.Never operate any CryoCool unit above -25°C.

Never operate any CryoCool unit above -25°C.

Older Cryotrols are equipped with a round 8 pin connector. If you wish to

connect your older Cryotrol unit to the CryoCool, an adapter cable is avail-

able from Thermo NESLAB. Contact our Service Department for more

information (see Preface, After-Sale Support).

A Thermo NESLAB Exatrol Digital Temperature controller may also be used

to control temperature. The Exatrol is designed for more precise temperature

control and offers tighter temperature stability than the Cryotrol.

Refer to the Exatrol manual for additional information.

Service Contracts Thermo NESLAB offers on-site Service Contracts that are designed to

provide extended life and minimal down-time for your unit. For more informa-

tion, contact our Service Department (see Preface, After-sale Support).

CleaningCleaning

Cleaning For proper operation, the unit needs to pull substantial amounts of air

through the condenser. A build up of dust or debris on the fins of the

condenser will lead to a loss of cooling capacity.

Periodic vacuuming of the condenser fins is necessary. The frequency of

cleaning depends on the operating environment. We recommend making a

monthly visual inspection of the condenser after initial installation. After

several months, the cleaning frequency will be established.

Cooling FluidCooling Fluid

Cooling Fluid The cooling fluid in the work area should be periodically replaced when

operating at low temperatures. At low temperatures, the cooling fluid may

collect water vapor from the air. As the concentration of water in the cooling

fluid increases, performance is adversely affected.

Loss of cooling capacity.

Make sure the heat load in the work area is not greater than the cooling

capacity of the unit. Refer to Section II, Specifications to review the cooling

capacity specifications.

Check for ice build up on the cooling probe. A layer of ice will act as

insulation and reduce the cooling capacity. Ice build up is often an indication

that the cooling fluid needs replacing. Defrost the cooling probe and change

the cooling fluid.

When the unit is shut off, wait approximately five minutes before restarting.

This allows time for the refrigeration pressures to equalize. If the pressures

are not allowed to equalize, the compressor will short-cycle.
