KR and VLT Series Coolers can be used to achieve low-
temperature capability with non-refrigerated circulators or boost the cooling
capacity of refrigerated circulators. They're also ideal for replacing dry
ice or liquid nitrogen. All models in the KR and VLT Series are designed to
run at maximum cooling rate; temperature control must be provided by an external
circulator.
Immersion
Probe style coolers
are excellent for trapping and dewar type applications and can be used to reduce
the expense of using dry ice or liquid nitrogen. A 3-ft. (.9 m) flexible hose
allows convenient placement of the cooling probe.
Flow-Through
style coolers
must be used in-line with a circulator pump. Because of their high cooling
efficiency, an anti-freeze solution is required in the circulating system.
