Abstract: The device is provided with a plurality of intermediate grid plate elements (12) with a top and a bottom surface, which are adapted to be positioned one on top of the other. Each intermediate grid plate element (12) comprises a grate strutting (18, 19) as well as a plurality of support members (20) which are distributed, in particular in a regular manner, over the intermediate grid plate element (12), wherein said support members (20) extend between the bottom face and the top face of an element in a direction substantially transverse to the extension of the intermediate grid plate elements (12) and are supported on the support members (20) of an adjacent intermediate grid plate element (12) arranged below a respective intermediate grid plate element (12), and support the support members (20) of an adjacent intermediate grid plate element (12) arranged above said respective intermediate grid plate element (12).

Abstract: A heat accumulator block for regenerative heat exchangers has a heat exchanger of a plurality of heat exchanger plates arranged substantially parallel to one another for formation of flow channels. A dirt collector is arranged upstream of a side of the heat exchanger exposed to an inflowing cold medium. The dirt collector consists of a plurality of protective plates which are arranged substantially parallel to the heat exchanger plates and have a plurality of spacers. The spacers are arranged between neighboring plates and connect the neighboring plates to one another. The spacers are positioned at a spacing to those edges of the protective plates which are exposed to an inflowing cold medium.

Abstract: A method for the manufacture of a component unit for heat exchanger, substance exchanger and/or bioreactor systems, with at least two walls joined together and composed of structured thermoplastic sheets, wherein a fused strip issuing from a melt shaping tool on the extruder head of an extruder is introduced, after passing through a precooling distance L, continuously into a strip molding press, and wherein the fused strip is continuously shaped in the strip molding press to form a structured plastic sheet and set by cooling. An apparatus for the practice of the method, wherein a melt shaping tool disposed on the extruder head, a continuously driven strip molding press, a system for the severing, stacking and/or winding and/or folding of the plastic sheets produced, and a cyclically operated bonding system are provided.

Abstract: A plate on which pipes of a floor heating system can be installed includes an abrasion-proof molded cover foil of relatively tough synthetic material and an insulation sheet of synthetic foam material, arranged below the cover foil, whereby the cover foil contains holding devices, molded in one piece as clamping fingers projecting from the foil material, for securing the pipes of the heating system. The insulation sheet is provided with protruding plugs which can be inserted into the hollow clamping devices of the cover foil, whereby the cover foil and insulation sheet are held together at least temporarily. There is also provided ribs for stiffening backs of the clamping fingers.

Abstract: A shaped mounting module for a liquid-type panel heating system is provided on which a heater pipe is mounted by means of discrete holder devices. In one embodiment, the panel is provided with a grid of flanges for supporting the heater pipe above the surface of the panel. In another embodiment, the panel is provided with a plurality of protrusions having their upper surfaces approximately level with the top of the mounted heater pipe to form a plurality of intersecting channels through which the heater pipe passes. Each of the holder devices has a plurality of opposite paired axially symmetrical openings formed by a plurality of axial symmetrical fingers having recesses therebetween. The heater pipe is either pressed into or passed through a selected pair of openings during assembly of the heating system. The holder devices are affixed to the panel either during the panel forming process or by adhesive bonding of the base into circular depressions on the panel during assembly of the heating system.
