About Us

Calidus Engineering Ltd was founded by Nigel Halladay, Managing Director and since December 2007 is the co-owner of the company along with Badger Explorer ASA of Stavanger, Norway. Enjoying steady growth throughout its history the last three years have seen the business takeoff both in turnover and staff numbers.

“… Badger Explorer bought into the company on recognising the technical competence and the significant contribution we were capable of making to their business goals and to ensure we would remain an accessible resource. Since then the stability and impetus that working with Badger has given us greatly enhances an already successful company and their encouragement in seeing Calidus expand into a larger but still independent endeavour will be to the benefit of all our clients” .. Nigel Halladay.

The client base continues to grow as do the technical challenges presented to us.

The Next Chapter
For over ten years the company has been based in Falmouth where it has been steadily expanding and out growing its facilities. On the 23rd, 2011 June we took over ownership of our new custom designed research and manufacturing facilities at Treleigh, Redruth which more than doubled our existing total work area with added advantage of bringing five locations together under one roof.

The Treleigh office is split into two discrete facilities - Calidus Research Centre and Calidus Manufacturing Centre (see contact page for address details). Within the Research Centre there is an extensive office and meeting room suite, laboratories for electronics and mechanics developments, large assembly and test area with a pressure test pit and borehole and ancillary facilities. The Manufacturing centre will house the mechanical manufacturing plant (relocates in August 2011) with its offices, inspection room and ancillary facilities.

We use SolidWorks 2011 for our mechanical CAD, SolidWorks Simulation Professional for static and dynamic analyses and Altium 2011 for electronic design, simulation and PCB development.

The manufacturing facility consists of a capable range of lathes, mills, grinders and wire eroder. A dedicated inspection area with a large coordinate measuring machine (CMM) and a comprehensive range of metrology equipment calibrated to national standards supports the manufacturing process to ISO-9001:2000.

Typical Projects
As a quick guide to what we do, a typical project takes one of two forms, either an upgrade or modification to existing equipment or the creation of a new device to meet the client’s requirements. That being said the complexity can range from simple to “never been done before” and very challenging.

The technologies used include:

- Materials for very hostile environments
- Seals for HPHT applications - +20kpsi
- [140MPa] / 750°F [400°C]
- Heat shields and thermal management systems
- Hydraulic systems to 35kpsi
- Electronics – memory and SRO, sensors & control

Application environments range from the benign to very high pressure and very high temperature.

Normal scope of operations
UK, Europe, North America and Japan.
