Accurate Plate-Groove Fit
The gasket profile is matched to the plate groove, port arrangement and attachment system. Correct geometry prevents the gasket from twisting, stretching or moving during plate-pack compression.
Aiprel plate heat exchanger gaskets provide reliable sealing and correct fluid distribution within gasketed plate-and-frame heat exchangers.

Each gasket fits into the groove around a heat transfer plate. It seals the plate perimeter and selected port openings, preventing external leakage while directing the hot and cold fluids through their designated channels.Aiprel supplies replacement heat exchanger gaskets in NBR, HNBR, EPDM, high-temperature EPDM and FKM compounds. Glued, clip-on, snap-on and stud-mounted configurations are available for Aiprel equipment and selected third-party heat exchanger models.

Heat Recovery Section: Heat is exchanged between unpasteurized cold ingredients and pasteurized hot ingredients.
Heating Section: The preheated ingredients are rapidly heated to the specified pasteurization temperature using an external heat medium. Cooling section: The sterilized and heat-insulated raw materials are quickly cooled to the temperature required for filling or storage through refrigerant or cooling water.
Plate Heat Exchangers’ high heat recovery rate is its greatest advantage in pasteurization. The preheating and precooling processes are nearly 90% energy self-sufficient, significantly reducing operating costs. At the outlet of the holding section, if the material temperature falls below the set sterilization temperature, the control system immediately activates a diverter valve, automatically transferring the material back to the balancing tank for reprocessing, ensuring 100% sterilization compliance.
The gasket profile is matched to the plate groove, port arrangement and attachment system. Correct geometry prevents the gasket from twisting, stretching or moving during plate-pack compression.
NBR, HNBR, EPDM, high-temperature EPDM and FKM options allow gasket selection according to fluid composition, temperature and cleaning conditions.
Aiprel can provide glued, stud-mounted, clip-on and snap-on gasket configurations for different plate designs and maintenance requirements.
Individual gaskets can be replaced during planned maintenance without replacing the complete plate pack, provided the plates and gasket grooves remain serviceable.
The gasket seals selected plate ports and guides each fluid through the correct channels, supporting stable thermal performance and media separation.
Replacement gaskets may be developed from a technical drawing, original gasket or matching heat exchanger plate when an existing model cannot be identified.

Selecting a gasket by heat exchanger model alone may be insufficient. The same equipment model may use different gasket compounds or attachment systems.
The following information should be confirmed:
Replace or inspect the gaskets when they show:
Leakage is not always caused by the gasket. Corroded plates, damaged gasket grooves, incorrect plate order and uneven frame compression should also be checked.
Aiprel gasketed plate heat exchangers deliver efficient heat transfer, compact construction, flexible capacity and easy cleaning for industrial applications.
Marine plate heat exchangers are essential components in shipboard cooling, heating, condensing and evaporation systems. By transferring heat efficiently between two fluids, they help maintain stable operating temperatures, improve energy efficiency and protect critical marine equipment.
Plate condenser is an indirect heat exchanger that converts vapor into liquid by transferring latent heat to a cooling medium through corrugated metal plates.
The Aiprel semi-welded plate heat exchanger combines the serviceability of a gasketed plate-and-frame unit with the enhanced sealing of welded plate cassettes. It is designed for processes where one medium is corrosive, hazardous, at an elevated temperature or otherwise difficult to contain with a conventional fully gasketed plate pack.
