The Gasketed Plate Heat Exchanger

The gasketed plate heat exchanger (GPHE) is a commonly used component in the petrochemical, food, and textile industries. However, its high stress level makes it vulnerable to failure. Despite its widespread application, little is known about the structural analysis of GPHEs. The vast majority of specialized literature is devoted to the thermal and hydrodynamic performance of GPHEs. Here, we report the results of experimental structural tests of two similar GPHEs with 316L stainless steel plates. We performed three procedures: single loading test, double loading test, and assembly test.

Spiral heat exchangers

Spiral heat exchangers are single-flow passages with uniform rectangular cross-sections. The spirals are designed to impart high heat transfer coefficients and minimize fouling. They can be used in a variety of applications including sewage treatment plants, aqueous solutions, and other industrial processes. The spiral design can handle a wide range of fluids including slurries, emulsions, and particle-loaded liquids.

This heat exchanger is available in single or dual-sided configurations. The spiral’s geometry eliminates contact with gasket surfaces, minimizing thermal fatigue. Additionally, it incorporates a clock-spring design that is highly flexible to accommodate thermal expansion and cyclic duty. This makes it suitable for many types of processes, including polyethylene production, phosphoric acid coolers, fertilizer plants, and molten sulphur coolers in refineries.

Spiral heat exchangers are a compact solution for many applications. They are easy to install and require less production space than traditional heat exchangers. This saves valuable production space and production cost. The spiral design is highly efficient, resulting in higher heat transfer efficiency. If you’re looking for an environmentally friendly way to cool your liquids, spiral heat exchangers are the right choice for your needs.

Double-wall or graphite plate heat exchangers

In double-wall or graphite plate heat exchanges, two plates are stacked one on top of the other. These plates are joined by laser welds around their ports. A thin air gap between them acts as a safety zone. This prevents fluid leakage. Further, these heat exchangers have a high surface area. For more efficient heat transfer, choose this type of heat exchanger.

Alfa Laval’s M Series plate heat exchangers are excellent solutions for general heating and cooling duties. These units feature a variety of sizes and material options. Alfa Laval’s M Series has superior cleanability, and is the only plate heat exchanger certified by the American Heat Exchanger Institute (AHRI).

Graphite or double-wall plate heat exchangers are more expensive than their metal counterparts, but are suitable for extreme corrosive environments. Their wide channels eliminate solids from bridging between adjacent plates, which is essential for applications that require a high level of safety and reliability. They can handle temperatures ranging from -10 to 350oF, and ranges from 0 to 20,000 gal/min.

Alfa Laval Diabon

The Alfa Laval Diabon(r) plate heat exchanger combines the highest efficiency in heat transfer with exceptional corrosion resistance. The unique combination of high turbulence and the corrosion resistance of graphite makes it an excellent choice for hard-to-treat corrosive media. With a compact footprint, it is easy to install and service. Compared to block and shell heat exchangers, the Alfa Laval Diabon(r) is a great choice for many applications.

The Diabon gasketed plate heat exchangers are made of high-quality materials. Alfa Laval offers two types: front and back, each with its own advantages. The FrontLine range is a premium range for food and dairy applications. The Diabon gasketed plate heat exchanger is suited to all industrial applications, including those with high temperatures and pressures. In addition, the WideGap is designed for high-viscosity, fibous liquids, and fluids with coarse particles, as well as pulp and paper processes.

Mueller Accu-Therm

The Mueller Accu-Therm plate heat exchanger is a highly versatile panel type. Its design allows for customization, and it is suitable for applications involving corrosive fluids or irregular shapes. Depending on your application’s specific needs, you can choose an Accu-Therm plate heat exchanger with an integral heat transfer surface, clamp-on unit, or immersion method.

The company is headquartered in Springfield, Missouri, and has manufacturing plants in Osceola, Iowa. Its customers include dairy farms and food processing facilities. These innovative processing equipments are used in food and beverage plants around the world. The Mueller Accu-Therm plate heat exchanger is an excellent choice for your application, and the company stocks many sizes in stock. It is available for same-day shipping, so you can be assured of rapid delivery.

The gasketed plate heat exchanger has a two-pass configuration, but you can also order a three-pass model or a four-pass unit. Some bigger models feature reinforcing partition plates. These products are also available in specialty ranges. In addition to the gasketed plate-and-frame range, Mueller offers a range of specialized plate-and-frame models.
