Here's an idea: you could pre-cool the air as before, using the 12 degC loop water before it went into your condenser hx. This would extract lots of moisture at uber-high COP. Directly downwind, the colder evap loop water hx would drop the air temp even better due to the reduced latent load. A double whammy.

You have built a 20,000 dollar industrial chiller. Now all it needs is a stainless steel rack mount enclosure around it and some big, ugly gauges. The bigger and uglier, the higher you could make the thing worth. Super sanitary.
