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
PID1
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.
Manually adjustable by-pass (handwheel) to reduce the pump capacity
(e. g. for glass equipment).
