600 Amps is correct.
The units will be cataloged as "Estate Chiller" and are for large single residences. If it helps to narrow things down the rep is in Connecticut. We have also built several for ski lodges and wineries.
They range in capacity from twenty to sixty tons with an integral dual pump package and a DDC controller.
Personally I thought that if they can afford that, then they can afford to get a three phase connection. The upper management people who designed the theory of the unit wanted to be able to install it on pre-existing 240 single phase hookups and let the customer worry about the electric bill.
