TEST CHAMBER SPECIALISTS
Engineered Solutions, designed and built in Britain
Our mission is to work closely with our customers to provide innovative solutions for their product development and quality assurance. As such, we are delighted to have been working on a project with Grayson Thermal Systems who is the market-leading supplier of cooling, HVAC and e-mobility systems across a variety of industries.
The design brief was to build a large environmental test chamber to provide controlled temperature conditions between -30°C and +55°C with some test loads dissipating up to 30kw.
The combination of a ceiling-mounted cooling unit, fitted with three EC fans and a speed-controlled Ecostar Bitzer condensing unit ensure maximum efficiency in full and part load operations.
Double doors and a removable aluminium ramp give easy access to a test area that is 2.8m wide x 3.8m deep and 2m high. The high load-bearing anti-slip floor is fitted with drainage points to facilitate the safe containment of test fluids used within the customer processes.
One wall of the room is fitted with an inlet and an outlet port allowing the customer to connect their test product up to an external conditioned temperature and humidity cyclone air supply. This cyclone air is mixed and conditioned in an insulated enclosure adjacent to the main test area where humidity is introduced via a steam lance. To give full testing flexibility two insulated stainless steel bungs are provided to isolate the cyclone system when it is not required.
As with any bespoke design, it is key that the customer interface is accurate, informative and easy to navigate, so for this JTS use the Watlow F4T touch screen programmable controller which permits custom screens to be created. Taking full advantage of ethernet connectivity the chamber can be run and monitored from a PC anywhere on the network.
With the chamber installed and commissioned, Grayson Thermal Systems can look forward to a future of reliable testing backed by our after-sales support for scheduled maintenance and calibration, with a quick efficient response should a breakdown occur.

James Technical Services Limited having been involved in electric car, battery development and testing over the past 7 years have now installed two 11kW charging points at the factory in Talgarth mid Wales. These points can be used by customers and employees š JTS have always been following the progress of the battery development and have purchased their first electric vehicle which will be used by the employees to carry out sales / site visits.  The container test chamber below is used by various car manufacturers for electric vehicle battery testing. This is just one example of a battery testing facility JTS can supply.
