  • Publication number: 20180296710
    Abstract: A sterilization apparatus for sterilization of objects. The apparatus includes a chamber for receiving the objects including a sterilization medium inlet and outlet; an inlet flow control device for controlling a supply of a sterilization medium to the chamber; a drain system for controllable discharge of fluid from the chamber; and a control unit configured to control the inlet flow control device and drain system. The drain system includes: a drain inlet connected to the sterilization medium outlet; a drain outlet connected to a vacuum system for evacuating the chamber; a first conduit connecting the drain inlet and outlet; and a proportional valve, arranged along the first conduit, controllable by the control unit to partly restrict fluid flow through the first conduit according. Drain valves may be controlled in response to the temperature of a flow of coolant, the coolant being used for cooling fluid via a heat exchanger.

  • Patent number: 9039990
    Abstract: The present invention relates to a ventilator autoclave comprising a chamber (1) with a space (5) for receiving goods (18) to be sterilized, at least one fan arrangement (2) for circulating steam and/or air in said chamber, and at least one first heat exchanger arrangement (11) for cooling and/or heating said steam and/or air, wherein said fan arrangement is arranged and configured to circulate said steam and/or air in said chamber (1), wherein said chamber (1) is configured such that said steam and/or air that is circulated in said chamber (1) follows a flow path passing at least a part of said first heat exchanger arrangement (11) before reaching said goods (18) to be sterilized, wherein said autoclave further comprises at least one second heat exchanger arrangement (19) that is provided upstream of said first heat exchanger arrangement (11) in said flow path, and wherein said second heat exchanger arrangement (19) is provided at such a distance from the periphery of said fan arrangement (2) that said flow
