Why we choose plate heat exchanger
Plate Heat Exchanger, sometimes referred to as a gasketed plate heat exchanger or GPHE, provides outstanding efficiency transferring heat from one liquid to another, often water to water, or from steam to liquid. This modular exchanger combines frames, plates and connections to form a variety of configurations. It is found in many of the same duties as shell and tube heat exchangers.
The plate heat exchanger is composed of a set of corrugated metal plates with four corner holes for the passage of two liquids for heat transfer. The metal sheet is mounted in a frame having a fixed plate and a movable pressing plate on one side and clamped by a clamp bolt. A gasket is placed over the plate to seal the fluid passages and direct fluid flow alternately into the respective passages to form a heat exchange. The flow, physical properties, pressure drop and temperature difference of the fluid determine the number and size of the plates. The corrugation of the plate not only increases the degree of turbulence but also forms a number of support points sufficient to withstand the pressure difference between the media. The metal plate and the movable compression plate are suspended on the upper guide bar and positioned by the lower guide bar, while the rod end is fixed on the support. On the column, but if one or both of the liquids pass through the heat exchanger more than once, the interface should be on the fixed plate and the movable compression plate. In most cases, one-way is used, and all the pipes are connected to the fixed platen. On, check the shoes to open the heat exchanger without disassembling the pipe.
Advantage of plate heat exchanger
INDUCED TURBULENCE
Promotes maximum heat transfer; induces scouring action that fights fouling or scaling.
REDUCED FOOTPRINT
Fits into 20–50% of a shell and tube footprint including service and maintenance space. And, it costs less.Hundreds of plate styles, patterns and draw depths to precisely match your application requirements.
Opens within its own footprint simply by loosening the tie-rod bolts and rolling the movable frame back to the support column.
Range of alloys, including titanium, plus variety of gasket elastomer compounds, to precisely match your fluid characteristics for maximum uptime.
HIGHLY VERSATILE
TEMPERATURE APPROACHES
Of less than 1°C (2°F), with “U” or “K “ values 3 to 6 times higher than shell and tube exchangers.
EASY ACCESSIBILITY
MAXIMUM FLUID COMPATIBILITY
Applications of plate heat exchanger
Rich plate type, various angles, various groove depths, different combinations to form a suitable heat exchanger suitable for working conditions, plate positioning system and single-side flow design and special clamping size marking. Easy to install and take over, run and maintain. Heat exchangers of different materials, such as stainless steel. Plates made of titanium or other special alloys to meet different industrial needs. Hot mixed form. By changing the flow pattern or increasing the number of flow channels, a myriad of combinations can be achieved, from a single flow of two fluids to a multi-flow flow of three or more fluids. Provide designers with a reasonable choice to meet different working conditions. Heat exchanger duties wherever operating temperatures and pressures do not exceed 180°C (356°F) or 27.5 bar (400 psi) Plate heat exchanger are widely used for cases like space-limited process expansions, HVAC, Heat recovery from low grade waste streams,viscous fluids or slurries, industrial fluids suitable for high heat transfer rates at low pressure drops.
