Hi

You might be able to find a system from the aircraft salvage companies – aircraft like the Beech 200 and 1900. SW Metros – etc. had them installed – if I remember correctly the King Air 200 was about a 18,000 btu system – double that with the aft evaporator installed. Try a look at Trade-A-Plane in the States or on Landings.

I am assuming this is needed for an aircraft – if not then check out the bigger truck companies – many of these units run 24 volt systems as well.

Remember that you will need a time delay in the system to turn on the compressor after shutdown – an immediate re-application of the compressor clutch after a disconnect will cause super high stress on the drive system – often breaking it – usually about 10 – 15 seconds time delay is sufficient to allow the high pressure side to equalize enough so that the next start-up doesn’t cause catastrophic failure. The King Air has the timer on a printed circuit board located under the floor – but you would need the wiring diagram to figure it out – any competent sparky should be able to design a timer interrupt circuit for the compressor clutch.

Good luck in the hunt.
