Abstract: A self cleaning filtering method and apparatus for a plate heat exchanger including: a suction pipe, centrally disposed within an inlet channel adapted for receiving a cooling medium therein for the plate heat exchanger; nozzles extending radially from, and in fluid communication with, the suction pipe, the nozzles spaced apart from each other; a low pressure chamber, external to the heat exchanger, abutting the pressure plate, the low pressure chamber in fluid communication with the inlet channel, and a section of the suction pipe extending into the low pressure chamber; a drain valve adapted to reversibly open a drain of the low pressure chamber; and a rotation mechanism controlling axial rotation of the suction pipe.

Abstract: A heat exchanging system includes a tank including a fluid inlet and a fluid outlet, which encloses (envelopes) a heat exchanger including a manifold tube and one or more one heat exchanging plates, extending from the manifold tube. The manifold tube includes a fluid intake and the fluid outlet, as well as a manifold barrier, which divides the interior of the manifold tube (for example, which is hollow), so as to define within the manifold tube an intake region and an outlet region. The heat exchanging system also has at least one heat exchanging plate extending from the manifold tube, the at least one heat exchanging plate with at least one plate barrier, such that the heat exchanging plate is configured to define a fluid flow path within the heat exchanging plate such that fluid flows from the intake region of the manifold tube.

Abstract: A ball trap screen for use with “T” type ball traps having a ball trap extension in which the ball trap screen includes a cone shaped inlet; an elbow, at least a portion of which includes a substantially planer solid area; a first screen section extending between the cone shaped inlet and the elbow; and a second screen section extending from the elbow into the ball trap extension; wherein at least a portion of the cone shaped inlet includes a cone solid blocking element, the first screen section includes a first solid screen blocking element and the second screen section includes a second solid screen blocking element. A method of enhancing the movement of the cleaning ball through the ball trap by blocking portions of a ball trap screen deployed within a ball trap housing so as to modify the fluid flow through the ball trap.

Abstract: The ball trap of the present invention is configured for connection in a pipeline such that the main flow path of the fluid in the pipeline passes through the ball trap. The ball trap includes a sieve conduit with a safety-release sieve gate. The sieve gate is displaceable between a closed position, in which cleaning balls are trapped in the ball trap, and an open position, in which the impedance of the fluid flowing in the pipeline is lowered. The system is configured such that the gate is normally in the closed position and may be displaced to the open position for cleaning purposes or in response to a predetermined pressure differential between the upstream and downstream sides of the sieve conduit.
