1.3 Application The Alfa Laval Pharma-line S is a high quality, double tube sheet shell & tube heat exchanger designed for the pharmaceutical and biotechnology industries. The Pharma-line S is used in pharmaceutical water systems: Water For Injection (WFI), Purified Water (PW), and for heating or cooling of pharmaceutical products.
1 Description 1.4 Design The Pharma-line S is in hygienic design in line with ASME BPE, USP and cGMP requirements. The Pharma-line S has no dead-legs and is fully drainable on the product side. All product wetted parts in the Pharma-line S are mechanically polished to Ra <0.5 µm or electropolished to Ra >0.4 µm.

1 Description Working principles In the Pharma-line S, the risk of mixing between the product and the heating or cooling (service) medium is eliminated as a result of the double tube sheet design. The product flows in the tubes while the service medium flows in a cross flow around the tubes, inside the shell.
2 Installation The Alfa Laval Pharma-line S can be installed either horizontally or vertically, on the floor, on the wall or in the ceiling. The flexible legs on Pharma-line S facilitate easy installation, either it is horizontally or vertically. For easy installation, lifting lugs are fastened to the unit with screws. Before lifting, make sure the lifting lugs are properly secured.
2 Installation 2.4 Levelling The heat exchanger must be set so that pipe connections can be made without forcing them. However, small forces may be unavoidable. Acceptable forces are as follows: - acceptable forces in all directions on the tube side are max 50 N - acceptable forces in all directions on the shell side are max 100 N 2.5 Cleanliness provisions Connector protectors...
2 Installation 2.7 Fitting and piping Bypass valves It may be desirable for the user to provide valves and bypasses in the piping system to enable inspection and repairs. Test connections It may be desirable for the user to install a thermometer well and pressure gauge connections close to the exchanger. Vents and drains It may be desirable for the user to install vent and/or drain valves close to the heat exchanger.
3 Operation 3.1 Design and operating conditions The heat exchanger must not be operated under conditions, which exceed those specified on the name plate. Warning! Failure to operate the heat exchanger within the design pressure and temperature specified on the name plate may result in damage to the heat exchanger and potential injury to adjacent personnel.
3 Operation 3.2.3 Shut-down operation The heat exchanger must be shut down in a manner that minimises different expansions between shell and tubes. If the system will be shut down for a shorter period, make sure the unit is filled up with water completely and no air is available in the system.
4 Maintenance 4.1 Inspection At regular intervals and as frequently as experience indicates, an examination should be made of the interior and exterior condition of the unit. Failure to keep all tubes clean may result in decreased performance of the heat exchanger. 4.2 Indication of fouling Heat exchangers subject to fouling or scaling should be cleaned periodically.
