The RU-200 consists 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. Dip Coolers work most efficiently when the liquid flows over the coil. May be used in any bath but the flexible hose must not be allowed in the liquid.
Test procedure: cooled a bucket of tap water from 15 degrees Celsius to 7 degrees Celsius in about an hour without circulation. Ice formed around the coil. See last photo.
