PRODUCT STRUCTURE
TYPICAL PLATE HEAT EXCHANGER COMPONENTS
EACH PLATE CONTAINS TWO COMPONENTS
Metal corrugated plate:different types of corrugated shapes are pressed according to different heat transfer conditions to ensure the best heat transfer effect.
Rubber washer:it is installed in the washer groove along the edge of the plate to form a seal and medium diversion.
TWO ROLES OF PLATE CORRUGATION
PLATE TYPE AND RUNNER COMBINATION
TWO DIFFERENT TYPES OF PLATES
PLATE TYPES WITH DIFFERENT CORRUGATION ANGLES
THE PLATES WITH TWO DIFFERENT CORRUGATED ANGLES CAN BE COMBINED INTO THREE DIFFERENT HEAT TRANSFER CHANNEL FORMS
EACH HEAT TRANSFER CHANNEL FORM CAN BE ASSEMBLED INTO A SINGLE PRODUCT STRUCTURE AND A DUAL-PROCESS PRODUCT STRUCTURE
PRODUCT CHARACTERISTICS
TYPICAL PLATE HEAT EXCHANGER COMPONENTS
·Other plate design
·Non-uniform medium shunt on the plate
·Reduced heat transfer efficiency
·Increased possibility of scale accumulation
·Letone’s plate is designed with a unique shunt structure that allows the media to evenly distribute flow across the entire plate, which has improved heat transfer efficiency and eliminated scale accumulation areas.
THE PARALLEL FLOW PLATE DESIGN MAKES MAINTENANCE EASIER
Parallel flow, better connection of pipe connections, reducing the total number of spare parts for plates and pads, making installation and equipment more convenient.
The parallel flow pipeline connection is better arranged, which has reduced the general category of spare parts of plates and rubber gaskets and made installation and equipment more convenient.
THE UNIQUE RUBBER GASKET STRUCTURE MAKES MAINTENANCE FASTER
Letone’s special plate protection groove prevents the gasks from being extruded and protects the plate for longer life.
The roof geometry allows the pad to withstand stress and tremor resistance, seal compression for longer durations, longer life and lower maintenance costs.
DOUBLE SEAL STRUCTURE AND SIGNAL LIGHT
SNAP-IN VISCOSITY-FREE GASKET
THE SUPERIOR CLAMPING BOLT SYSTEM MAKES MAINTENANCE EASIER
The unique and superior clamping bolt system consists of the bearing box systems, bolts, and fixation systems. The bearing box system allows the bolts to be quickly and accurately seated and easily tightened, and the fixation system can prevent the bolts from rotating when tightened. All bolts are rolled and coated with anti-corrosion materials and lubricants. The outer cover is made of plastic, the heavy-duty hexagonal nut makes the whole assembly and disassemby process easier, and disassembly process easier, and all the clamping bolts can be removed and installed from the side for easy disassembly.
ACCURATE MULTI-POINT POSITIONING SYSTEM MAKES MAINTENANCE EASIER
An accurate multi-point positioning system is adopted for Letone’s detachable plate heat exchanger. The four-corner positioning system of the type with the diameter of the corner hole less than 100mm allows the guide bar above and below the plate to be accurately embedded together as the axle center. The five-point positioning system of the type with the diameter of the corner hole more than 150mm allows the plate to be positioned by multiple metal-metal contact points, where the contact points of the upper guide bar can prevent the plate from moving up and down, and the contact points of the lower guide bar can restrict the plate from moving left and right. By adopting multi-point positioning technology, the plate group can move forward and backward without resistance on the guide bar, complete maintenance work easily and simply and make the plates accurately assembled during the reinstallation, the gaskets sealed accurately and exactly and the plate group completely reset, thus ensuring the life of the heat exchanger after disassembly and assembly is also more durable. Moreover, the plate heat exchanger with a multi-point positioning system only needs one person who can easily disassemble and assemble the heat exchanger with a simple tool even without any experience, which is unmatched by other plate heat exchangers.
INTERNATIONAL ADVANCED GASKET PRODUCTION PROCESS
British advanced rubber formula and raw materials provided by manufacturers interna-tionally renowned are adopted for Letone’s plate heat exchanger, and then professionally formulated by domestic well-known rubber engineers. The gasket produced has no irritating odor and conforms to product grade standards.
The heat transfer oil is heated and vulcanized to ensure a smooth high temperature required for vulcanization and make the rubber sufficiently vulcanized. The international advanced technology of secondary vulcanization is used for gasket primarily vulcanized to ensure better performance of the gasket.
Letone can customize various types of gaskets from different manufactures at home and abroad according to the drawings, samples, and plates provided by customers. The quality is reliable and the speed is fast, which solves the problem of maintenance without gaskets for the majority of the plate heat exchanger users.
