Description of Models
The models of this series of refrigeration units are designed to provide low temperature capabilities for
circulators and baths without refrigeration, or for those requiring additional cooling.
Immersion Coolers provide convenient cooling and reduce the need for dry ice or liquid nitrogen in
dewar flasks. These units do not have integral temperature controls. They only run to their full cooling
capability. Immersion Coolers have a flexible hose connected to a probe. The probe serves as the
evaporator in the refrigeration cycle and is normally immersed in a dewar flask or cold trap.
Flow-Through Coolers are designed to be used in conjunction with circulators or other controlled
heating and pumping devices. They are built with a copper tube-within-a-tube heat exchanger. The
fluid to be cooled is circulated through the space between the tubes while the refrigerant evaporates to
produce cooling inside the inner tube. The fluid contact with the cold evaporator inner tube produces
very efficient heat removal from the fluid.
