We instruct our customers on the proper maintenance of our systems and products. In addition, we often offer training and provide equipment to assist our customers in performing their own maintenance. When required, support may be provided by a local support team or by specialists sent from our facilities. We also provide performance based logistics services.

We generally offer a one or two-year warranty for our systems and products following delivery to, or installation by, the customer. In some cases we offer longer warranty periods. We accrue for warranty obligations specifically determined for each project based on our experience and engineering estimates. These accruals are intended to cover post-delivery functionality and operating issues for which we are responsible under the applicable contract.
