2. OPEN LOOP, CONVENTIONAL CENTRICLEANERS

3. CONCERNS IN OPEN LOOP, CONVENTIONAL CENTRICLEANERS
Need of individual cleaner feed and accept valves
Open reject pit
Fiber loss from Reject Pit spills & overfows
Air intrapment from open reject vertex
Larger parts for replacement (high cost)
Heavy maintenance time & cost

4. CLEANPAC 700 LD

5. CLEANPAC 700 LD – Advantages
Satellite assemblies
Smaller replaceable parts
Twin wall design
Large cleanout plug
Transparent reject chamber
Transparent lower cone and lower shell
Low density reject removal system

6. SATELLITE ASSEMBLIES Design flexibility Installations in smaller space
In spite of compact design enough maintenance space
Quick and easy replacement of complete cleaners and spares

7. SATELLITE ASSEMBLIES

8. SMALLER REPLACABLE PARTS
No need of changing complete cleaners
Smaller parts can be changed if damaged or worn out
Parts assembled with O rings and clamps. Quick and easy replacement of parts
Less time and manpower required for Maintenance
CLP 700 LD Assembly

9. TWIN WALL DESIGNTM Well proven design
Fig A – leakage through shell vent
Fig B – Protection plug sealing the vent
No immediate shut down for maintenance
No pulp splash if inner cone worn out in running
(FIG A)
(FIG B)

10. LARGE CLEAN OUT PLUG Lower risk of clogging of reject pipe
Large outlet minimizes risk of clogging caused by oversized particles
Easy access to inside from bottom to clean and flush the cleaner

11. TRANSPARENT REJECT CHAMBER
Visual access to reject transfer
Large clean out plug
Easy inspection of the individual cleaners for clogging

12. TRANSPARENT LOWER CONE AND LOWER SHELL
Visual access to complete lower cone assembly
Helps to understand the flow pattern and running condition of individual cleaners
Proved to be very helpful in high reject containing pulps and critical cleaning applications

13. LOW DENSITY REJECT REMOVAL SYSTEM
CLP 700 LD cleaner removes low density rejects from pulp like
Plastics
Hot melts
Stickies
Waxes
Free air

14. CELLECO TWISTERTM

15. CELLECO TWISTERTM Satellite assemblies Smaller replaceable parts
Twin wall design
Operating consistency of up to 2 %
Transparent reject tip
Transparent lower cone and lower shell

16. COMPARISON OF CLEANERS LOW V/S MEDIUM CONSISITENCY
NO. OF CLEANER UNITS
PRIMARY
SECONDARY
TERTIARY
FIBERMIZER
TWISTER 9 2 1
CLP 700 18 6
Less number of cleaner units per stage
Fewer Stages for bigger plants
Less maintenance cost
