As you are well aware, Harrison Radiator’s participation in the Preheater Program has been terminated, and you have been advised to stop all work on the timer/controller. This unfortunate situation, however, should not overshadow the Preheater Product Development Team’s positive assessment of Nartron‘s overall performance on this project:

Technical competence & innovation, excellent communication, sensitivity to cost targets, adherence to timing benchmarks (in spite of evolving product definition), and the intensity of all involved to work-with a sense of urgency, are just some of the key areas your organization is to be commended. In essence, you have satisfied your customer.

We have relayed the above to Volvo Flygmotor who is currently reformulating their strategy regarding O.E.M. preheater applications. We expect they will be contacting you within the next month.

Again, thanks for your very capable efforts. It was a pleasure being associated with Nartron Corp. on this program.
