Before using any uid or performing maintenance where contact
with the uid is likely refer to the manufacturer’s MSDS for handling
precautions.
When using a process uid mixture of ethylene glycol and water or
propylene glycol and water, check the uid concentration and pH on
a regular basis. Changes in concentration and pH can impact system
performance. See Section 3.
Many refrigerants which may be undetectable by human senses
are heavier than air and will replace the oxygen in an enclosed area
causing loss of consciousness. Contact with leaking refrigerant
will cause skin burns. Refer to the chiller's nameplate and the
manufacturer's most current MSDS for additional information.
Performance of installation, operation, or maintenance procedures
other than those described in this manual may result in a hazardous
situation and may void the manufacturer's warranty.
Transport the chiller with care. Sudden jolts or drops can damage its
components.
Drain the chiller before it is transported and/or stored in near or
below freezing temperatures, see Draining in Section 8. Store the
chiller in the temperature range -25°C to 60°C (with packaging), and
<80% relative humidity.
For ThermoFlex900-10000 chillers, the circuit protector located on
the rear is not intended to act as a disconnecting means.
Observe and never remove warning labels.
Never operate damaged or leaking equipment.
Never operate the chiller without process uid in the reservoir.
Always turn off the chiller and disconnect the power cord from
the power source before performing any service or maintenance
procedures, or before moving.
Never operate the chiller with panels removed.
Never operate equipment with damaged power cords.
Refer service and repairs to a qualied technician.

• Cooling capacity based on P 2 pumps with no backpressure. Heat input from the pump will result in a reduction in cooling
capacity. The cooling capacity reduction will vary based on the pump chosen as well as pump backpressure and ow.
• Specications obtained at sea level using water as the recirculating uid, at a 20°C process setpoint, 25°C ambient
condition, at nominal operating voltage. Other uids, uid temperatures, ambient temperatures, altitude or operating
voltages will affect performance. See Section 3.
• Additional dimensions are at the end of this section, add 1/8" (3 mm) to height for SEMI.
• Add 5 pounds (2 kilograms) for global voltage chillers.
• Thermo Fisher Scientic reserves the right to change specications without notice.
Section 2 General Information
The Thermo Scientic ThermoFlex
TM
recirculating chiller is designed to
provide a continuous supply of uid at a constant temperature and ow
rate. The chiller consists of an air-cooled or water-cooled refrigeration
system, heat exchanger, recirculating pump, polyethylene reservoir, and a
microprocessor controller.
Description
Specifications
* Pumping capacity pressure values for turbine pumps are differential pressures between the inlet and the outlet of the
chiller. Specications for MD 1/MD 2 pumps are identical to P 1/P 2.
