Thermal Shroud is Go!
We are pleased to announce that the thermal shroud system has been fully installed and tested for our TVAC#2 vacuum chamber.
Previously the system could be configured with a passive baffle unit with infrared tubes for elevated temperatures (for thermal cycling or monitored thermal vacuum bakeout) but this was limiting for cold temperatures where the system relied on conduction via the thermal interface plate and the item under test.
The shroud system consists of four independently controllable banks of IR heaters (allowing asymmetric heating of an item under test) with fluid lines coupled to the back of the tooling plates which can take either coolant from our chiller circulator systems or LN2 for cryogenic temperatures (an automated fill system maintains the LN2 level within the shroud plates).
This not only improves the performance of our TVAC#2 thermal vacuum chamber in terms of thermal cycling, but also reduces down time between tests as no reconfiguration is required.
Simulators in Demand
Having delivered a large, advanced 4-zone close match solar simulator to one of our existing customers at the end of 2020 we have since seen a considerable increase in inquiries for solar simulators from the very start of 2021.
We have not been resting on our laurels in terms of leading the world in advanced, multi-zone solar simulators; we have developed the LED boost systems we use to take advantage of the latest developments in the LED market. As such we can build a Unisim 300 solar simulator to operate under our N-zone technique. This essentially reduces the footprint and electrical requirement to achieve a 4-zone Unisim 300 (previously quite a large instrument) down to what is a 2-zone system with LED units.
As always, if you are interested in what we can achieve with our close match solar simulators (or any of our products or services) please get in touch.
The major, integral components of our solar simulators (enclosures, HMI lamp power supplies, custom optical filters and optical components) are all manufactured by UK companies in the UK. We design our power distribution and electonric control systems in-house which are then wired by a UK company (in the UK). The simulators themselves are designed, built and tested by us in the UK and we have supplied companies and laboratories across the world.
For our in-house test chambers and facilities we design our own thermal control systems, thermal interface plates and shrouds. The manufacturing and finishing (plating, anodising etc.) of these parts is outsourced to UK machinists and engineering companies. Heating elements and cooling systems are all sourced from UK companies who manufacture in the UK. Final assembly and testing of the systems is, of course, conducted by ourselves.
As you can tell, we are serious about supporting UK manufacturing and working with UK companies for every aspect of our business and we are constantly looking to expand our contacts in this regard. If you are a UK manufacturer and you think your products could be of interest to us, please feel free to get in touch with us and let us know.
At the start of 2020 we took delivery of a new TVAC chamber which we had scheduled to come online mid 2020. However during the UK covid-19 response in March we undertook large scale improvements to our test house involving a new floor being poured and laid along with a complete re-wiring of the laboratory to support the additional equipment we have installed. This required a complete dismantling of all of our test chambers and equipment in order to clear the lab.
Due to this disruption, along with the increased test and manufacturing demand in the second half of the year, we have had to delay the commissioning of TVAC#3 into 2021. Work has continued on the machining of the thermal exchange plate and installation of the pumps on the chamber system. However final run-up and testing is not scheduled until the start of 2021. Once ready the additional chamber in our facility will increase throughput and reduce wait times for TVAC tests.
We would like to take this opportunity to thank all of our customers who have either been using us for years or have just found is this year. We realise being busy is a very nice problem to have right now and so we thank you for choosing us for your test work.
