A plate-type heat exchanger consists of a pack of corrugated metal plates with openings through which two fluids pass, and heat is transferred through the spaces between these corrugated metal plates. The plate pack is incorporated between a fixed frame plate and a movable pressure plate, and it is compressed by tightening bolts. Gaskets attached to the plates seal the spaces between the plates while guiding the fluids alternately through the channels. The number of plates is determined by flow rate, temperature conditions, fluid characteristics, and pressure loss. The corrugation of the plates promotes turbulence in the fluid and provides a structure that can withstand pressure differences. For more details, please contact us or refer to the catalog.

The Twin-plate is a "plate type" developed to handle fluids that can penetrate rubber gaskets and highly permeable fluids. It creates a bag-shaped cassette plate (Twin-plate) by laser-welding the sealing parts of two plates, and a gasket is attached to this combination. Alternating flow paths are formed with welded flow paths and gasket-sealed flow paths, allowing fluids that can penetrate the gasket to flow through the welded flow paths. It is ideal for cases where the use of gaskets is not possible on the process liquid side and where disassembly and cleaning are required on the other side, making it effective in refrigeration systems using ammonia refrigerants, heating and cooling of solvents or process liquids, and district heating and cooling. For more details, please contact us or refer to the catalog.

Graphite is a "plate type" that performs best against highly corrosive fluids. Instead of metal, corrosion-resistant graphite is used. With the numerous features of the "plate type" that are not required in other types of heat exchangers, excellent corrosion resistance is added, enabling compatibility with fluids that are difficult to handle with metal "plate types." It can be used for heat exchange of strong acids such as hydrochloric acid, medium-concentration sulfuric acid, hydrofluoric acid, phosphoric acid, and many corrosive organic liquids in chemical plants, significantly improving heat exchange efficiency compared to other types of heat exchangers. For more details, please contact us or refer to the catalog.

The TS-M is a plate-type heat exchanger developed primarily for fluid heating using steam as the heating medium. With the adoption of an innovative design for the heat transfer plates and special gaskets, it can efficiently respond to situations where rapid temperature changes are required on the heated side, which has been a problem with conventional plate-type heat exchangers when using steam heating, as well as to small temperature changes of 2 to 3 degrees Celsius. It quickly responds to various changes in operating conditions, ensuring stable heat exchange. Its robust design is also resistant to thermal fatigue, allowing it to withstand harsh operations with steam and providing excellent durability. Additionally, it is very compact compared to the widely used multi-tube heat exchangers for steam, requiring less installation space and making it easy to modularize in combination with other equipment. For more details, please contact us or refer to the catalog.

The evaporator is a compact yet highly efficient device that concentrates solutions by evaporating solvents such as water. It is constructed by laser welding the seal areas of two plates to create a bag-shaped cassette plate, which is then combined with a gasket. The welded flow paths and gasket-sealed flow paths are arranged alternately, with steam passing through the former and process liquid flowing through the latter for concentration. The pressure loss during evaporation is significantly smaller than that of conventional plates due to a specially designed plate pattern, which also minimizes uneven flow. In addition to being used for the concentration of sugar solutions, its applications have expanded to various fields, including alcohol distillation and sludge concentration. For more details, please contact us or refer to the catalog.

Brazed Plate is a plate-type heat exchanger composed of stainless steel (SUS316) plates that are brazed with copper or nickel in a vacuum heating furnace, along with two cover plates.

Wide-gap is a "plate type" developed for heat exchange of fluids containing fibers and coarse particles, as well as fluids with high viscosity. In conventional "plate type" and other types of heat exchangers, fluids that tend to clog are addressed with wide-gap flow paths. This prevents blockages within the unit even with easily clogging fluids, significantly reducing the frequency of cleaning. Furthermore, the unique wavy plates generate advanced turbulence in the fluid, dramatically enhancing heat exchange efficiency. It demonstrates performance that exceeds the limits of multi-tube heat exchangers in processes such as sugar production, fermentation alcohol distillation, chemical processes, and the paper and pulp industry. For more details, please contact us or refer to the catalog.

Double-wall is used in processes where dangerous reactions are expected when two fluids mix, such as in bioplants, where mixing accidents could have adverse effects on the external environment. It employs a special pair-plate with a double structure, combined in the same manner as conventional "plate-type" designs. In the unlikely event that cracks or pinholes occur in the plates, the fluid will flow out through the gap of the pair-plate to the outside of the heat exchanger, preventing the mixing of the two fluids and allowing for safe operation. It can accommodate applications that have traditionally used multi-tube heat exchangers, double circuit intercoolers, and indirect heating coils, and is effective in various processes including the cooling of transformer oil, heating of drinking water, and in chemical, bioplant, food, and pharmaceutical manufacturing. For more details, please contact us or refer to the catalog.

It is designed to maintain the high efficiency of heat transfer performance of plate-type heat exchangers while eliminating the risk of mixing between the two fluids. In the case of a double-wall heat exchanger, if either of the two fluids flowing through the heat exchanger leaks, it will manifest as a leak to the outside of the heat exchanger, allowing for maintenance to be performed by halting operation.

The Pharma-X heat exchanger uses a unique triple-tube structure with a tube-in-tube design, where the product liquid flows through the central tube and the heating/cooling medium flows through the inner and outer tubes. Additionally, spiral coils are arranged in each flow path to create uniform gaps between the flow paths and increase heat transfer efficiency. Turbulence minimizes the risk of biofilm formation. The three tubes and spirals are bent at a 180-degree angle to form a U-shape. Due to its compact design, space can be utilized optimally. The U-tube absorbs thermal expansion, allowing it to function effectively across a wide temperature range as a cooling and heating device, and it is also capable of steam sterilization.

Wide gap plate heat exchangers were developed for the purpose of heat exchange with fluids containing fibers or coarse particles, as well as fluids with high viscosity. They accommodate fluids that tend to clog in conventional "plate" or other types of heat exchangers with wide gap channels (flow paths) of 16mm or 22mm. This design prevents blockages within the unit even with fluids that are prone to clogging, significantly reducing the frequency of cleaning. Furthermore, the unique wavy plates generate advanced turbulence in the fluid, dramatically enhancing heat exchange efficiency.

Alfa Laval manufactures small spiral heat exchangers suitable for all applications and small spiral heat exchangers suitable for sludge treatment.
