Generally, it should be carried out in accordance with the requirements of rubber amine, such as light protection, ventilation, keeping away from ozone, etc., and has certain temperature and humidity requirements. When not in use for a long time, the rubber strips should be loosened to a certain extent to prevent permanent deformation and maintain elasticity. Let’s take a look at how the world’s major plate heat exchanger manufacturers, Tranter, Ampere, GEA, and Alfa Laval, store temporarily unused heat exchange equipment. Tranter plate heat exchanger equipment should be stored for more than 6 months and should be stored according to the following procedures: 1) Empty the medium in the equipment and blow dry (preferably use compressed air at about 65C℃ (150℉) ； 2) Seal flange or pipe openings and seal all other openings ； 3) Anti-rust and anti-corrosion measures should be taken on the surface of regular steel ； 4) Reduce the compression amount of the rubber strip and adjust the clamping size. It is recommended to adjust to 1.2L. When in use, clamp to clamping L. 5) Cover the equipment with opaque heat insulation, reflective or similar plastic to prevent direct sunlight, thermal radiation and ultraviolet radiation and ensure ventilation ； 6) It is best to store indoors at a temperature of 15℃-21℃ (60℉-70℉). The temperature is less than or equal to 70%; the equipment is not allowed to be placed at 0℃ (32℉) or below. ； 7) Keep away from ozone sources. The long-term storage of API plate heat exchangers should be carried out according to the following procedures: 1) Indoor storage at a temperature of 15℃-21℃ (60℉-70℉) ； 2) Loosen the clamping studs and plate bundle so that the plate bundle is in an unclamped state ； 3) Cover the heat exchanger with plastic film ； 4) Avoid heat radiation and ultraviolet radiation. There are no motors and welding equipment indoors. ； 5) Take anti-rust measures on the surface of carbon steel parts (such as bolts and flange surfaces). If GEA plate heat exchanger equipment is stored for a period of time (1 month or more), the following measures should be taken: 1) The plate heat exchanger is suitable for storage indoors, with the indoor temperature at 15℃-20℃ and the maximum humidity of 70% ； 2) 2) Ensure that there are no ozone sources, no organic pre-agents and acid solutions stored indoors, and avoid thermal radiation and ultraviolet radiation. ； 3) Empty the media in the device ； 4) 4) Loosen the plate bundle to 1.1L. Then clamp it to L when in use. ； 5) The plate bundle is covered with opaque film ； 6) Take anti-rust measures for the clamping studs. When Alfa Laval plate heat exchanger equipment needs to be placed for a long time (more than 1 month) before use, in order to prevent unnecessary losses of the equipment, appropriate protective measures should be taken: 1) The equipment is best stored indoors with an indoor temperature of 15℃-20℃ and a humidity of about 70% ； 2) There should be no ozone-generating equipment indoors, such as electrodes, welding equipment, etc. Ozone has a destructive effect on many rubbers (electric cracking) ； 3) Organic volumes and acid solutions cannot be stored indoors, and thermal radiation and complex external radiation should be avoided. ； 4) It is best to put the equipment in the packaging box before installation ； 5) Metal plates are best covered with opaque plastic film ； 6) The surface of the bolt should be painted with a good anti-rust liquid ； 7) The heat exchanger should be drained, and depending on the media being processed, it is recommended to clean and dry the equipment before storing it. The above is the storage guide for these big brand plate heat exchanger manufacturers. If your equipment also needs to be stored, or will not be used for a period of time, learn these methods!
