PM for Plate/Frame T he plate and frame Heat Exchanger

The plate and frame heat exchanger is an engineered piece of equipment that serves as a means of energy transfer. Heat transfer involves bringing two fu-ids at different temperatures closer to each other, so that one either heats or cools the other. This means that energy already paid for is simply transferred to another part of the process. This saves energy and reduces the overall environ-mental impact of the production or system.Heat-Exchangers

The basic plate heat exchanger consists of a series of thin, corrugated plates that are gasketed or welded together (or a combination of these) depending on the liquids passing through them. The plates are then compressed together in a frame to create an arrangement of parallel fow channels. One fuid travels in the “odd numbered” channels, and the other in the “even” channels.A plate and frame heat exchanger can be used in almost any environment and for multiple applications. Its compact design allows for mounting where space is limited. The plates in the heat exchanger are used for both heating and cool-ing—they are generally made of stainless steel, but can alsoHeat-Exchangers
be made of any pressable material that is resistant to aggres-sive media, like geothermal water or seawater. Plate heat ex-changers are also adjustable and can be modifed to adapt to process changes over time—the number of plates can be eas-ily expanded or reduced to meet application requirements.The plate and frame heat exchanger consists of three main components—plates, gaskets and a frame. They can also be ftted with additional features for different applica-tions, including insulation, drip tray and a protection sheet.

Plates, gaskets and a frame are the three main components of a plate and frame heat exchanger. in addition to being used in a variety of applications in indoor climate control, they can also be used to recover excess heat in industrial plants and environmentally friendly climate control.

Plate and frame heat exchangers are fexible and feature a compact design, allowing for installation in many different types of applications. Plate heat exchangers can be used for indoor climate con-trol—for cooling during the summer (or in tropical zones) and for heating in colder climates, as well as for heating of tap water or swimming-pool heating or cooling. Plate heat exchangers can also be used to recover excess heat in indus-trial plants as well as for environmentally friendly climate control. Typical applications include:gDistrict cooling;gLocal cooling;
gFree cooling;gPressure interceptor;gGlycol saver; and gChiller bypass.PM for optimal performance The heat exchanger is a silent machine with no moving parts and is often regarded as a “no maintenance needed” piece of equipment, but this not the case. Although the maintenance
