IMPORTANT RECALL NOTICE DATE: 04/23/2018 Dear Valued Customers: Chart has received reports of a vacuum leak or failure that could compromise the product and may affect Aluminum Dewar models listed below. The reliability, safety, and quality of our products is of utmost importance to Chart Industries. In addition to this communication, we will personally call you to verify receipt of this recall notice. We take seriously the trust you and your customers place in the quality of Chart’s products. Please contact us at MVEtankservice@chartindustries.com if you have any questions or comments. Thank you for your business and cooperation. SERIAL NUMBERS AFFECTED: Aluminum Dewars with Serial Number Range: NPB201750xxxxx through NPB201752xxxxx and NPB201801xxxxx through NPB201810xxxxx (manufactured Week 50 of 2017 through Week 10 of 2018). A list further describing potentially affected Model numbers and names is provided at the end of this recall notice. This recall does not pertain to Chart products manufactured anywhere other than New Prague, Minnesota, USA. This recall does not pertain to Chart’s Stainless Steel Cryogenic freezers. ISSUE: Chart is presently investigating the possible cause of the VACUUM LEAK AND/OR FAILURE which may be due to inadequate adhesion of the composite neck to the aluminum unit. Based on information to date, this issue appears to be an isolated occurrence involving the machine and binding agent used during the manufacturing process. Chart is recalling with immediate effect the affected models and will replace affected units.
