1. Intended use
JULABO immersion coolers have been designed for temperature application to specific fluids
in a bath tank.
For example: Dewar vessels, beakers, or other containers in conjunction
with heating circulators for continuous countercooling
or for dry-ice substitution.
JULABO immersion 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 JULABO immersion coolers FT200, FT 400 and FT900 are employed to cool liquids for
working temperatures ranging from +50 °C to -90 °C, such as in:
Dewar vessels, beakers, or other containers
in conjunction with heating circulators for continuous countercooling
or for dry-ice substitution.
The JULABO FD200 Flow-Through Cooler is employed to cool liquids in closed circuits. This
unit is generally installed at the intake of a heating circulator to draw heat away from the
circulating bath liquid.
Models FD200, FT200 and FT400 are provided with a handle for portable use.
Model FT900 is equipped with four castors. Two of the castors include locking levers that
should be pressed down after setting up the unit to prevent it from moving.
The immersion probe is connected to the instrument with a flexible, specially insulated tube.
On model FT900 the immersion probe is also flexible and may be adjusted precisely to
different positions within the vessel.

according to common safety regulations. This section explains the potential dangers that
may arise when operating the circulator and also specifies the most important safety
precautions to preclude these dangers as far as possible.
The operator is responsible for the qualification of the personnel operating the units.
 The personnel operating the units should be regularly instructed about the dangers
involved with their job activities as well as measures to avert these dangers.
 Make sure all persons tasked with operating, installing, and maintaining the unit have read
and understand the safety information and operating instructions.
 When using hazardous materials or materials that could become hazardous, the circulator
may be operated only by persons who are absolutely familiar with these materials and the
circulator. These persons must be fully aware of possible risks.
