Pit Mounted Dragout Systems

Pit Mounted Dragout Systems operate under the same principles as the Floor Mounted Dragout Systems. These large systems combine two methods of removing impurities from coolant: the dragout conveyor in the settling tank and the Encyclon cyclonic filter. These two methods work together to filter the dirtiest coolant to 5 microns.

Recommended Use:

As a central coolant system. For use with single or multiple machine tools generating large quantities of swarf.

How the System Works:

Dirty coolant from your machines is returned to the dragout tank, where large, heavy particles settle out by gravity. A moving drag flight conveyor sweeps the tank bottom, carries these particles out of the dragout tank and deposits them in a swarf container, leaving coolant free of any large particles. The conveyor has three important features to ensure trouble-free operation:

  • An adjustable timer provides exact control (continuous or intermittent) to suit any application.
  • A unique, self-cleaning wiper blade discharges all contaminants into a swarf cart. No particles can be returned to the settling tank.
  • A built-in safety clutch automatically actuates a switch, stopping the conveyor and energizing a trouble light if extremely heavy resistance is encountered by the conveyor.

Reading the Model Number

The Encyclon Model Number (listed in the first column of each table) indicates features of that particular system.

The first two digits of an Encyclon system's model number refers to the Type of Cyclone: Type 28 for 3 micron filtration, Type 65 for 5 micron filtration. After the type is the Number of Cyclones and then a dash. Following the dash is the Total Coolant Capacity, in gallons. If there is a Special Feature, an abbreviation is added to the end (for example, DT stands for Dual Tanks).
