Cold Filter Update

• Temperature controller– Jeremy is obtaining the special plug to hook

up to laptop– Will get plugs for heaters’ power supply– Cannot access program until temperature

controller is in computer

• Can now operate program from desk

Cold Filter Update (con’t)

• Added another thermocouple– Designed to take ambient temperature of

freezer– Will run temperature controller from this one

and fuel tank only– Thermocouple in filter will be collected but not

controlled

Future Work

• Temperature controller– Finish the heaters– Hook-up to laptop and program

• Do preliminary test runs with ULSD
