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.
