Section II General Information

The Thermo Scientific ULT 80 and ULT 95 are self-contained refrigerated
bath/circulators. The circulators consist of a circulating pump; heater; stain-
less steel reservoir; microprocessor temperature controller; and a cascade
configuration, air-cooled refrigeration system.
The refrigeration control is independent of the main power switch so that the
compressor may be turned off to allow fast warm-up. The automatic load
reset feature compensates the proportioning for changes in the bath load,
thereby eliminating shifts in setpoint accuracy.
