Topsfield Engineering Service, Inc.

Topsfield Engineering Service, Inc. has been providing engineering support to high technology companies for over thirty years. In the last fifteen years this work has increasingly been for projects and programs involving spacecraft, space and airborne optical systems, cryogenic refrigeration systems, thermal/vacuum chambers and concomitant cryogenic & vacuum pumping facilities, optical and electro-optical systems.

TES is an alliance of senior engineers and analysts with a combined 175 years of experience. We specialize in the Concept Engineering/Design (Process and Thermodynamic) of major industrial projects for Space Simulation, Vacuum Processing and Cryogenics.

Companies that we have worked for include: DEC, Cambridge Acoustics Research, CHART Industries, Inc., Foxboro Co., HVEC, Honeywell/Loral, Kendall Co., Kestrel Corp., Kollmorgen Corp., Lambda Physik, ITEK, Lockheed Martin, Raytheon, L3 Communications/SSG, SORL, FLIR Corp, and Datum TT & M, to mention some of them.

Our technical specialties include, satellite payload thermal and structural analysis and design, opto-mechanical design, ground test facilities, and cryogenic storage & distribution.

During the detailed phase of most projects, TES audits the designs of the Prime A&E and the critical Vendors to ensure that requirements of the Project’s Process Design are met. TES also contributes to the overall Value Engineering and Risk Management Plan.

TES also specializes in Structural Analysis of Cryogenic Vessels for Large Stationary Tanks, Large Trailer Trucks, and Rail Cars used for critical service (H2, O2, N2, etc.)

Our goal is to provide engineering, analysis, and technical support in design and test systems development for clients on a confidential and ‘as needed’ basis.

Why use us?

  •  We have decades of experience in thermal, structural, and thermoelastic analysis, design of cryogenic refrigeration and chamber thermal conditioning components and systems. Our experience also spans significant fabrication, startup, and testing.
  •  We are available and dependable. We do have a current workload; however we all have time in our work schedules to support new work. We can support you and you can depend on us to see the project through to successful completion.
  •  The latest software tools are used for our design and analysis work – Sinda/Fluint 5.6, Thermal Desktop 5.6, Nastran, AutoCAD, Inventor, and many others.
