Spec Engineering and AD Process Equipment Merger

Over the past few months, there have been quite a number of changes at Spec Engineering, a Gray company, and we appreciate your continued business and patience with us. As you may remember, a new leadership team and overall restructuring with Anderson Dahlen Inc. started taking place in July, with a new entity, AD Process Equipment, being formed. We are already impressed with the collaboration!


As of December 5, 2022, Spec Engineering will be merging with AD Process Equipment as we continue to grow the manufacturing division of Gray. AD Process Equipment will continue to have a close relationship with Anderson Dahlen, including common management.


We apologize for any inconvenience this change has caused you or your business over the past few months. We understand that operating Spec Engineering and AD Process Equipment as two separate companies may have presented some challenges during this transition, but it was necessary at the time. We hope you have seen how dedicated our team members are at making your project a success.


The AD Process Equipment team looks forward to continuing to work on your project, with the same level of skill, experience, and expertise you have come to appreciate with our team.
