Unit selection

Checklist 4: Screws

1 through 8 essential for determining unit

1    Machine manufacturer, type and serial number.
2    Set-value temperature of screw.
3    Heat transfer fluid.
4    Processing material.
5    Processing rate (kg/h).
6    Heating capacity (kW) and cooling capacity (x kW at screw temperature y °C).
7    Operating voltage (V/Hz), 3 PE.
8    Pump capacity (x l/min at y bar).
9    Cooling water mains: pressure and temperature range.
10  Accessories (hoses, couplings, etc.): see "Regloplas Temperature Control Technology",
      section "Accessories".
11  For optional features, see «Regloplas – Temperature Control by Means of Fluid Media,
      5th edition», page 17, section 8.
12  See also Checklist 1 for additional information pertaining to problem, as well as Checklists 9
      and 10.

Important: Because the amount of frictional heat and the pressure drop across the screw are not known, the data requested in points 6 and 8 must be calculated by the machine manufacturer under specification of the data requested in points 1 through 5. The correct temperature control unit cannot be determined without these values.
