Kryoeinrichtung und zugehoeriges Betriebsverfahren zum aktiven Brandschutz

(A1) Die Erfindung betrifft eine Kryoeinrichtung zur Kryokonservierung von Kuehlgut, insbesondere von biologischen Proben, mittels eines Kuehlmittels, insbesondere fluessigem Stickstoff. Die Erfindung sieht zur Brandbekaempfung eine Feuerloescheinrichtung (4, 10) vor, die das Kuehlmittel als Loeschmittel benutzt.

DE 102007024842 A1 UPAB: 20081222 NOVELTY - The cryo device has a fire extinguishing unit that uses the cooling agents as fire extinguishing agents. Fire alarms (7,8) are provided for fire recognition in the cryo device and for activating the fire extinguishing unit in case of fire. A cryo tank (1) receives the refrigerated goods and a coolant inlet pipe (2) to supply the coolant to the cryo tank. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an operating method for the cryo device. USE - Cryo device for cryoconversion of refrigerated goods, particularly biological goods by coolant such as liquid nitrogen used in the cryo device as fire extinguishing agents for fire fighting (all claimed). ADVANTAGE - The fire alarms are provided for fire recognition in the cryo device and for activating the fire extinguishing unit in case of fire, and hence ensure an effective fire protection.
