Temperature Sleeves

There has recently been some discussion on what units still have temperature sleeves built in. It is important to know the design goals of each series of cryogenic freezers before going into a discussion of which units do and do not have sleeves. MVE and stock series cryogenic freezers can be used for vapor storage but are designed for liquid nitrogen storage. Top box temperatures below -125°C cannot be expected even with the vapor sleeve installed. Increases liquid nitrogen usage notes that installation of a vapor sleeve. If your customer requires reliable temperatures in vapor below -120°C then MVE -150 (High Efficiency) and -190 (Vapor Storage) freezers are the one to be steered.

 

MVE stock series cryogenic freezers do not have any sleeves available for them and achieve vapor a vapor temperature of -120°C in their stock form such as the MVE 103, MVE 811, and MVE 1318. Both stock series MVE 1842P-150 and MVE 1877P-2T achieve -150°C in vapor phase. For any -150 (High Efficiency) or -190 (Vapor Storage) models Vapor sleeves are not available. 510, 616, 1223, 1426, 1839 are the following models have built-in temperature sleeves. For that particular freezer both the hanging temperature reduction sleeve and the appropriate vapor platform included in the vapor pack.
