Plate and Frame Heat Exchanger
Aeon PEC has provided compact thermal transfer solutions through plate and frame exchanger technology for more than 50 years. With a broad range of plate and gasket options, our engineers can help guide you through the process of selecting, sizing and installing the correct exchanger.
Four main types of plate and frame heat exchangers are:
Gasketed Plate heat exchangers use gaskets to seal the plates together to prevent leaks. These gaskets and plates can easily be removed for cleaning, expansion or replacement with minimal maintenance costs.
Brazed Plate heat exchangers primarily used in many industrial and refrigeration applications. These exchangers are highly resistant to corrosion due to the stainless steel plate composition with copper brazing. These exchangers are extremely efficient and compact making them an exceptional economical selection. Brazed Plate exchangers are used in oil & gas, chemical, petrochemical, refinery, and other industries. Design criteria includes: ASME, PED, ML (China) in compliance to ISO 9001 quality standards.
Welded Plate heat exchangers are much like the gasketed plate exchangers, but instead the plates are welded. This provides increased durability and are ideal for transferring fluids that are high temperatures or corrosive. Since the plates are welded, mechanically cleaning of the plates is not an option.
Semi-welded plate heat exchangers contain a combination of welded and gasketed plates. These exchangers contain pairs of two plates welded together which are then gasketed to other pairs which allows one fluid path to be welded and one gasketed. This allows one side of the exchanger to be serviced and cleaned with the other capable of handling high pressure and corrosive fluids. The semi-welded style heat exchanger is great for transferring expensive fluids because the risk of fluid loss is small.
