  • Reversible flow evaporator system
    Patent number: 11644243
    Abstract: A reversible flow heat exchange system includes a heat exchanger system that includes a canister configured to receive a first fluid from a machine and a heat exchanger disposed within the canister. The reversible flow heat exchange system also includes a cooling system coupled to the heat exchanger and configured to circulate a second fluid between the heat exchanger system and the cooling system and a reversing valve coupled to the heat exchanger and configured to selectively direct a flow of the first fluid in a first direction through the canister and in a second direction through the canister that is opposite the first direction.
    Type: Grant
    Filed: November 8, 2021
    Date of Patent: May 9, 2023
    Assignee: Hyfra Industriekuhlanlagen GmbH
    Inventors: Gerhard Lahnstein, Berthold Adomat
