Portable and central liquid chillers have their place in the heat transfer market.
But if selected improperly or expected to perform beyond design specifications, then issues will arise along with operator frustration.
Although Central and Portable liquid process chillers are refrigeration devices for process cooling and heat transfer, they are two different breeds.
PORTABLE liquid chillers are designed to cool one use point.
CENTRAL chillers are designed to provide cooling water to an entire facility and servicing multiple use points.
Since the objectives of these chillers are radically different, they therefore, are different. In some cases portable chillers can be ‘modified’ with some standard options to act as a central chiller. However, the portable chiller does not and will not provide all the benefits of a central chiller.
This comparison pertains to Advantage Engineering Maximum portable chillers and Titan central chillers.
