Hi all .

I need to find a vendor for a chamber to hold aircraft alumniun parts at -40ºC or -40ºF

It shall be 20 ft (6 meter)length, 10 Ft wide (3 meter) , 10 ft Heigth (3 meter), inside size.

It will have a double door 2 meter by 2.5 m height on a end.

and 2 windows , at each side 0.80 x 0.80 meter

Loading rate is about 100 kG once per hour , with doors full open .
Incoming temperature 40ºC , cool rate to reach -40ºC , 6 hours.
When the doors are opened , the temperature shall not be upraise to -35ºC .
Air curtain , and PVC stripe shall be install , both at doors and windows.
Double 100% compressor and evaporator , as to have 100% backup.
No pre chamber allowed , by site space
This chamber is to stop aluminium hardening after heat treatment, to keep it soft until further processing the parts.

Thanks in advance
