Hi:
I am modifying a Transicold Ultra unit to use as a chiller for a methanol distillation column, and will need some ballpark ideas.

The specs I have say that the unit is rated at 21,000 btu for -20F return air temp, and 46,000 btu for 35F.

Anyone out there able to guess or calculate what general capacity I can estimate for a 148F return air temp? Looking to do the bulk of the condensation duty with this unit, and finish it with a chilled water condenser. I figure the total heat duty required is around 40kW.

thanks,
ccaissie
