Carbonate freezers
Carbonates accumulating in alkaline baths impair their performance. The freezer cools the bath to the temperature at which carbonates precipitate, filters them out and returns the purified bath to the tank.
Effector GM
WEF 100 carbonate freezer
Welded construction in 304/316 stainless steel. OMRON CP1L PLC control with a touch-screen operator panel.
Operating cycle
- 01FillingA diaphragm pump draws the bath into the jacketed tank; the refrigeration unit and glycol pumps start.
- 02CoolingGlycol in the jacket cools the bath to the set temperature, while an agitator mixes it.
- 03FiltrationThe bath flows through the extractor's mesh belt; the frozen-out carbonates are collected in a bag.
- 04HeatingThe filtered bath is heated in the lower tank.
- 05EmptyingThe same pump returns the bath to the tank; the system rinses itself automatically.
