Constant temperature water bath with exocyclic
Thermo supplier

EZL-81F
Product Code:0043200-000

External circulation while using water bath is available. Addressed to high temperature, silicon oil can be used as well.



Combination example of EZ-101 and throwing type cooling device

Main Application

Circulation to device which need temperature regulation at high temperature
Quality test at high temperature using water bath

Features

EZL-81F with built in freezer

Space-saving designed of vertically aligned water bath and freezer. Equipped with freezer protection circuit to enables stable use at +100 ºC.

External circulation with variable flow rate, watering surface is made of all stainless steel

It is optimum to circulate into precise device by variable flow rate. Since all watering surface is made of stainless steel, heat resistance and sanitary quality is improved.

(*) When circulating medium is at +10ºC
When setting below +7ºC, please use antifreeze (see option)
When setting around RT - +60ºC, please circulate cooling water (tap water) in cooling pipe (please ask). Temperature rise by work heat from mixing pump need to be minimized at above +40ºC because freezer stops.
When setting above +70ºC, please use heating medium for high temperature (see separately sold parts).
Please do not use pure water or distilled water as heating medium. These may cause breakdown of machine.
