Patent number: 10934516Abstract: A method for controlling electrical power consumption for a first group of functional which can be used for operational management during operation of the bioreactor components during operation comprises, inter alia, adjusting a present power control signal for one or more of the functional components from the first group in order to optimise power consumption, when a comparison shows for the first group of functional components that the currently required total electrical power consumption is greater than a predefined total electrical power consumption, such that, for the first group of functional components, an adjusted total electrical power consumption is not greater than the predefined total electrical power consumption. A biotechnological apparatus comprises a bioreactor, a reactor vessel formed in the bioreactor and having a cultivation chamber, and a temperature control device provided with a heat pump and configured to control the temperature of the cultivation chamber.Type: GrantFiled: July 25, 2017Date of Patent: March 2, 2021Assignee: DASGIP Information and Technology GmbHInventors: Matthias Arnold, Guido Ertel, Sebastian Selzer

Patent number: 10717960Abstract: This patent document relates to the field of biotechnological apparatuses. It relates particularly to a biotechnological apparatus comprising a bioreactor, an exhaust gas temperature control device and a method for treating an exhaust gas stream. This patent document further relates to a connection device for a sterile single-use fluid conduit of a single-use bioreactor and to a method for treating a fluid stream. The reusable connection device comprises a receptacle in which a portion of the fluid conduit can be detachably arranged, and a coupling member connecting the connection device to a temperature control device, the receptacle having a contact surface which is arranged such that the contact surface abuts a fluid conduit arranged in the receptacle, and wherein a portion of a fluid conduit can be introduced into the receptacle in a direction running substantially orthogonally to a longitudinal axis of the connection device.Type: GrantFiled: October 10, 2012Date of Patent: July 21, 2020Assignee: DASGIP INFORMATION AND TECHNOLOGY GMBHInventors: Matthias Arnold, Heinz Gerhard Köhn, Nico Gülzow, Sven Eikelmann, Guido Ertel, Sebastian Selzer
