Abstract: The invention relates to a plate heat exchanger including a plate package, which includes a number of first and second heat exchanger plates which are joined to each other and arranged side by side in such a way that first and second plate interspaces are formed. At least two injectors are provided, each injector being arranged to supply a first fluid to at least one of the first plate interspaces in the at least one plate package and at least one valve is arranged to control the supply of the first fluid to the at least two injectors.

Abstract: A plate heat exchanger includes a plate package having first and second heat exchanger plates. The plates are joined to each other and arranged side by side so that a first plate interspace exists between each pair of adjacent first and second heat exchanger plates, and a second plate interspace is formed between each pair of adjacent second and first heat exchanger plates. The first and the second plate interspaces are separated from each other and provided side by side in an alternating order. Substantially each heat exchanger plate has at least a first porthole forming a first inlet channel to the first plate interspaces. At least two injectors are arranged in a wall portion of the first inlet channel and extend from the exterior of the plate package to the first inlet channel interior, and each injector supplies a fluid to more than one of the first plate interspaces.

Abstract: The invention refers to a heat exchanger plate and a plate heat exchanger. The heat exchanger plates are arranged beside each other in the plate heat exchanger to define several first plate interspaces for a first medium and several second plate interspaces for a second medium. Each heat exchanger plate comprises a heat transfer area, an edge area, which extends around and outside the heat transfer area, and a functional device, which is configured to receive or produce a signal. The heat exchanger plate also comprises a communication module provided on the heat exchanger plate. The communication module comprises an electronic circuit connected to the functional device and a module antenna. The communication module is configured to permit wireless communication of the signal with a master unit via the module antenna.

Abstract: The invention refers to a plate heat exchanger and a heat exchanger plate. The heat exchanger plate for a plate comprises a heat transfer area and an edge area, extending around the heat transfer area. The heat exchanger plate is a double wall plate formed by two adjoining plates compressed to be in contact with each other. The heat exchanger plate comprises a sensor which is configured to sense at least one parameter and to produce a signal depending on the parameter and that the sensor comprises a sensor probe that is provided between the adjoining plates.

Abstract: The invention relates to a plate heat exchanger (100) comprising a package of heat exchanger plates (1), two end plates (2, 3) between which the package of heat exchanger plates (1) is kept together, a plurality of threaded bolts (9), where the bolts (9) extends between the end plate (2) and a drive unit (10) and through the end plate (3), the drive unit being arranged for synchronously rotating the bolts (9) and having bolt heads (11) arranged to bear directly or indirectly against one (2) of the end plates, a plurality of nuts (12), each in threaded engagement with one of the bolts (9) and arranged to bear directly or indirectly against the other end plate (3), the bolts (9) and nuts (12) being arranged for movement of one of the two end plates (3) toward or away from the other, the drive unit (10) further comprising a rotating arrangement each of the bolts (9), and a motor (14) in driving engagement with rotating arrangement each of the bolts (9) for simultaneous rotation of all the bolts (9), where the bo
