the design, development and manufacture of electro-optical systems,
sub-systems, modules and components to meet the needs of defence,
aerospace, civil, industrial and space markets around the
Brief: In October 2005, Grant Instruments
was approached to provide temperature control systems for two wet
benches to coat glass sheets used in head up display modules in
military and civilian aircraft. We were asked to improve an
original design. The process requires rapid heating and cooling of
individual tanks within a 25 - 35°C temperature range.
Grant's skill and technology: The
combination of Grant Flow heater technology and re-circulating
chillers and system integration combined to give us the building
blocks to rapidly develop a system to make measurements.
The outcome: Grant's solution was to heat each
tank via a stainless steel coil heat exchanger with our new FH60
flow heaters with added priming reservoirs and modified
controls. The cooling for each bench was provided by one
RC3000G re-circulating chiller. The heaters and cooler were
connected to the heat exchangers via a system of valved manifolds
and interconnecting pipework. This allowed for individual control
of each tank. The system was installed at a new premises 3 months
after the order.
Our tests showed that our stability, uniformity and speed of
response met, and in some cases, exceeded the specifications laid
down by the customer.
