1. PURPOSE

It is established to provide a proper procedure to decrease the water temperature according.

2. SCOPE

It is applicable in Infusion manufacturing department.

3. RESPONSIBILITY

Maintenance officer (Mechanical / Electrical)
Maintenance Supervisor (Mechanical / Electrical)

4. PROCEDURE

The Heat Exchanger with instrument is handled in the following way.

5. MAINTENANCE

MONITORING OF MACHINE MAINTENANCE:

Time to time check each and every part of Heat Exchanger according to the maintenance schedule.
Check the following parts carefully.
 Heat Exchanger Plate
 Gaskit
For its Maintenance:
Unscrew the Heat Exchanger to dismental the plates of a heat exchanger.
Check all the gas kits if find any problem in any of damage replace all the gaskit set. It is no recommended to change only one of damage if have som problem.
For plates washing dip all plates in HCl. (Diluted in water).
After washing now its time to go for a fitting procedure of a Heat Exchanger.
During fitting take care about the sequence (which is mentioned on the plates).
Clearance gap must be taken place with in limits (limits are shown on plates).
While assembling the Heat Exchanger even tightness should be taken place.
After making it clear, now its time for leakage checking procedure (start up the pump to check leakage if any).
If find any kind of leakage then tight evenly to stop leakage.

This activity is then documented in the form Machinery & Equipment Maintenance Log

Check the Heat Exchanger condition time to time to find any kind of problem during operation.
All the monitoring record is filed and kept by the Maintenance Supervisor.

EMERGENCY / BREAKDOWN MONITORING:

Maintenance Manager receives Maintenance Work Order duly signed by the section incharge of the concerned machinery or equipment.
