1. Intended use
JULABO recirculating coolers have been designed for temperature application to specific fluids. The
pump connections can be used for cooling applications in an external circuit at a constant
temperature.
JULABO water baths are not suitable for direct temperature control of foods, semi-
luxury foods and tobacco, or pharmaceutical and medical products. Direct temperature
control means unprotected contact of the object with the bath medium (bath fluid).
1.1. Description

RS232
 The recirculating coolers are operated via the splash-proof keypad. The
implemented microprocessor technology allows to set and to store the setpoint that
can be indicated on the LED temperature display.
 The PID temperature regulation is used to withdraw heat from the bath fluid by
means of the cooling machine and to automatically regulate the required need.
 Electrical connections:
1. The serial interface RS232 allows modern process technology without
additional
interface.
2. Alarm output for external alarm message.
