Carrier 30HXC condenser approach temperature

[capaula]

I have been searching in Carrier product data for design approach temperatures for HX water cooled chillers but cannot find anything.

Do they not publish this info? If you do not know the design approach temperature how do you figure out if your approach temp. is too high due to dirty tubes,scaling etc.?

Any idea of what kind of approach I can expect there?

Thanks

HX water cooled chillers should be 5 to 7 degree approch on the condenser
