Anyone with a background in electronics over the past 15 or 20 years will undoubtedly have come across housing cabinets. If an electronics control centre developed a problem, the chances are the problem would lie within such a cabinet.
Diagnostic technicians in the media and broadcasting industries would affectionately refer to them as “the racks”. These huge safe-like cabinets were over 8 feet high and invariably contained a variety of permanently overheating components including that most wondrous of antiques, “the valve”.
Audio valves, ignition valves, transmitter valves and RF heating valves. All housed together in heavily insulated felt lined cabinets often provided welcome warmth on a cold winter morning when the temperature elsewhere in the station was well below the Union’s minimum guidelines. Cabinets back then were there to house and protect the valves from the elements and also to prevent leads and cables which could cause injury and toxic emissions.
The invention of the transistor changed racks forever and electronics housings are now highly sophisticated pieces of equipment in their own right. It’s a common cliché, but since the development of the latest micro-processors, a single Cannon Smart EP custom design cabinet can house over 30 million times the communications capability of a data campus with less than 1/1000th of the electronic power. More impressive is that the sophistication of the Cannon Tech housing requires almost zero maintenance.
Components which harness such power need to be protected and maintained at constant state and tolerance. Cannon’s unique designs offer a bespoke solution for all component preservation requirements including easy expansion and movement facility. Cabinets can be easily bayed, allowing for all manners of configuration to be adopted and continually adapted; and yes, they even have their own thermostatic temperature control.
An Internet search suggests there’s still a demand for the old valves and transistors, personally speaking, I think it’s time they cooled off.
