  • Device for catalytic treatment of fluids
    Patent number: 6986871
    Abstract: A device for catalytic treatment of a first fluid medium and for changing heat between the first fluid medium and a second fluid prior to or after the catalytic treatment comprises a plate heat exchanger (1) of the type in which the plates (2) are rigidly interconnected by welding or soldering. A catalyst carrier (21) has been detachably fastened to the plate heat exchanger (1) and protrudes into one of the ports (7) of the exchanger (1).
    Type: Grant
    Filed: February 8, 2001
    Date of Patent: January 17, 2006

  • WATER HEATER COMPRISING A PLATE HEAT EXCHANGER AND A STORAGE CONTAINER FOR HEATED WATER
    Publication number: 20030108344
    Abstract: A water heater adapted to avoid peak temperatures of delivered water comprises a plate heat exchanger (1) connected to a storage container (2) provided with interior reinforcing means (9-11. FIG. 1; 13-13′″. FIGS. 5-18) connecting opposite parts of the outer wall (2′) of the container (2). Even provided with a thin storage container wall this makes it possible to use a box shaped water heater design without risk of deformations due to variations in the water pressure. The reinforcing means may consist of stacked interconnected plates (13-13′″). e.g. having the same form and size as plates (12-12′″) used in a plate heat exchanger connected to the container (2).

  • Water heater comprising a plate heat exchanger and a storage container for heated water
    Patent number: 6574427
    Abstract: A container (2) adapted to avoid peak temperatures of water delivered from a heat exchanger (1) is provided with interior reinforcing means (9-11, FIG. 1; 13-13′″, FIGS. 5-18) connecting opposite parts of the wall (2′) of the container (2). Even with a thin container wall this makes it possible to use a box shaped container design without risk of deformations due to variations in the water pressure. The reinforcing means may consist of stacked interconnected plates (13-13′″)—e.g. having the same form and size as plates (12-12″) used in a plate heat exchanger connected to the container (2).
