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 recirculating coolers 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
The recirculating cooler consists of
•
control unit with splash-proof keypad (microprocessor technology)
•
cooling compressor
•
heater
•
heating/cooling bath and recirculating pump
The electronics comprises two microprocessors that provide reciprocal monitoring via
sensors for the working and safety circuit.
The actual and setpoint temperatures are permanently visible on the MULTI-DISPLAY
(LED 1 + LED 2) and thus may be easily compared.
The bath tank is located in the lower part of the unit. The cooling machine draws heat
from the bath liquid via the cooling coil (evaporator). If the setpoint lies above the
ambient temperature, the integrated heater produces more heat.
The integrated circulating pump ensures constant conditions for the external cooling
loop and provides a good circulation of the liquid in the bath tank.
The unit provides analog electrical connections and a serial interface.
Safety installations: High temperature and low temperature limits, both adjustable via
the MULTI-DISPLAY, as well as low liquid level protection.
2. Operator responsibility – Safety instructions
The products of JULABO ensure safe operation when installed, operated, and
maintained according to common safety regulations. This section explains the
potential dangers that may arise when operating the recirculating coolers and also
specifies the most important safety precautions to preclude these dangers as far as
possible.
