Technical Support/Returns

For technical support, or to obtain a return material authorization (RMA), please contact TESI by e-mailing customer.support@teledynees.com or calling 410.891.2375. Prior to e-mailing or calling, please have the model and serial number of the system (typically located on a label attached to the gas system), recently recorded data, and a record of recent maintenance available. Companies on the distributor/representative list with an asterisk (*) can also be contacted for technical support.

Spare Parts

Teledyne stocks a large quantity of frequently needed spare parts to ensure quick delivery. Purchasing direct from TESI saves you time searching for a vendor and provides you with the confidence that the replacement part will be compatible with your system. The best way to ensure that parts for your system will be available when needed during maintenance is to retain a small stock of critical maintenance items at your facility. Please ask for a maintenance spare parts kit that includes commonly needed items to maintain your system. Contact a representative or distributor in your area (see list below), or TESI by e-mailing customer.support@teledynees.com or calling 410.891.2375.
