Title: Progress at Protensive
1Progress at Protensive A brief update for the
December 2004 PIN meeting Ian Henderson, RD
Director, Protensive
2Progress at Protensive.. New equipment 4 100mm
SDRs rated to 200C, full vacuum to 4barg 2
200mm SDRs rated to 220C, full vacuum to 4barg
300mm High temperature unit 400C, full vacuum,
with polymer handling capability ie cone
discharge and gear pump High stability gear
pump units, extruder, mono type pump All computer
interfaced,Oil baths with high output pumps
3 Progress at Protensive High heat transfer on
SDRs Overall heat transfer coefficient of
10kW/m2 K (1761 Btu/ft2h F) for low viscosity
process fluids and water or glycol as heat/cool
fluid. A 0.5m dia disc with delta T 20K will
transfer 39kW. thanks to patented double spiral
disc design, copper construction (with chrome
plating for corrosion resistance)
4Double Spiral Design
Rectangular channels no fine clearances. Low
thermal and mechanical mass Constant disc
temperature Flow independent of rotation
Chrome plated copper construction
No distortion under pressure/vac
