INTRODUCTION
Read the whole of this book before commencing work with the unit.
The book applies to a range of Techne fridge units, Dip Coolers RU-
200 and RU-500 and Flow Coolers FC-200 and FC-500. Hence
paragraphs or sections without a heading or reference apply to all
units while paragraphs or sections with headings apply to specific
units. For Refrigerated Baths there is a separate booklet.
The Techne fridge units are designed to cool liquids to temperatures
around ambient and below by extracting heat continuously. The
temperature is controlled by a temperature controller with a heater
adding heat as necessary. Depending upon the circuit and the
application this could be a Techne Thermoregulator, TE-10 series or
TU-20 series, or it could be a Techne Circulator, the C-85A or C-
85D. Each unit, fridge or controller, has its particular application
which should be considered when setting up a temperature
controlled system.
Dip Coolers
The RU-200 and RU-500 are designed to work with Techne
laboratory baths and thermoregulators without reducing the working
area of the bath. They consist of a refrigeration unit where the
evaporation coil is on a flexible hose. The coil is placed in the liquid
and heat is extracted as the coil cools. The Dip Coolers work most
efficiently when the liquid flows over the coil.
The Dip Coolers are designed so that the cooling coil fits in the
corner of a Techne bath supported by a special cover on the bridge
piece. However they may be used in any bath but the flexible hose
must not be allowed in the liquid.
