The stand alone Hybrid Cooler and shell and tube exchanger start out at amount $20k. This will get the mash down to 105F in summer, colder from Fall thru Spring. Additional cooling would need to be done in the fermenters by a chiller if needed.
You can reduce the size of the hybrid cooler by setting up a two stage cooling by cutting in the chiller sooner running with with a chilled water reservoir. It all depends how much chiller you need during summer. The Hybrid Cooler will get nearly triple the cooling in off seasons, so if you are not running a chiller 24/7, it may be cost effective to integrate the chiller in the crash cooling, but only when needed, so you can keep your power consumption at a minimum. For a 1000 Gal system, this is a sizable savings which we can determine for you. The Hybrid Cooler will pay for itself in a few years from power savings.
