1. Intended
use
JULABO circulators have been designed to control the temperature of specific fluids in a bath 
tank. 
 
JULABO circulators 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
The circulators 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 control adapts the heat supplied to the thermal 
requirements of the bath. 
Safety installations conforming to IEC 61010-2-010 
The excess temperature protection is a safety installation independent from 
the control circuit. 
The safety value is set using a tool (screwdriver). 
If the low level protection device is triggered, a complete shutdown of the 
heater and circulating pump is effected.
