A heater comprises an inlet for a medium to be heated, an outlet for the medium, and at least two cassettes. Each cassette comprising a first plate comprising a first main surface and a second plate comprising a second main surface. The first and second plates are attached to each other and enclose a respective flow channel for the medium. The cassettes are arranged beside each other with a space between the cassettes for an electric heating element. The electric heating element abuts the first main surface of one of the cassettes and the second main surface of the adjacent cassette. The heater comprises two distance members extending between the one cassette and the adjacent cassette. The distance members define the space.

Heater and a heat exchanger installation

Device that includes a housing with a stationary part configured to receive liquid into the device and a rotatable part arranged with the stationary part. The rotatable part is rotatably arranged with a hub with at least one spray nozzle. In the housing there is an axis with one part connected to a rotation generating element in the housing and another part provided with threads forming a worm screw. The worm screw fits into the threads of an adjacent first gear wheel forming a worm gear. The worm gear transmits rotational force from the rotation generating element via the axis for rotating the hub and the rotatable part. The rotation generating element, the axis and the worm gear are arranged in a flow path for liquid passing through the device, whereby the bulk of the liquid flows through the worm gear in a direction towards at least one spray nozzle.

Device for cleaning closed spaces

A flushing device () includes a flush liquid pipe () arranged in an enclosed space () with at least one flush head () which is substantially rotatable about the longitudinal axis (A) of the flush liquid pipe, and a nozzle device () arranged on said flush head, being substantially rotatable about an axis (B) extending substantially transversely to the longitudinal axis of said flush liquid pipe, having one or more nozzles () for the provision of one or more flush liquid streams () directed substantially against the inside of the enclosed space for the cleaning thereof. To provide a flushing device () which also permits cleaning of components of the flushing device () which are located within the enclosed space (), at least one of the one or more nozzles () of the nozzle device () are arranged and/or formed such that at least a portion of the flush liquid streams (and) from the nozzle during at least a portion of the rotation of the nozzle device contacts the flush liquid pipe () along a portion of the periphery of the flush liquid pipe and such that at least the portion of the flush liquid stream from the nozzle contacts the flush liquid pipe during rotation of the flush head () along the entirety of, or a portion of, its periphery, thereby cleaning the flush liquid pipe.

Flushing device

Devices for cleaning of enclosed spaces by means of liquid sprayed out. The device comprises a housing with a stationary part to which the liquid is supplied and on which a rotatable part bearing a hub is mounted. The hub has at least one spray nozzle. An element suspends the hub in a bearing in the rotatable part. The rotatable part comprises a turbine driven by the liquid and having a planetary gear for turning the rotatable part and at least one nozzle so that the liquid sprayed out by at least one of the nozzles during rotation sweeps across the inside of the enclosed spaces. The stationary part comprises an upper ring gear in engagement with a lower ring gear on the hub, which two ring gears are surrounded by the housing. The turbine and the planetary gear are fitted in the rotatable part to achieve a compact device.
