Water Cooled Portable Chiller

Berg has packaged more high-performance and convenient features into our air and water cooled portable chillers. Plus, with our extensive list of available options, we can customize the portable chiller specific to your needs.

Best of all, we’ve kept our line of portable chillers remarkably affordable.  Just choose the capacity that’s right for you, from 3/4 to 40 tons.

Portable chillers are particularly useful for small sized loads, special types of fluid and pressures, temporary use, and test applications. All of Berg’s portable refrigeration units come with a liquid chiller circuit and a pump tank system for a complete solution, and can also be configured to include a remote condenser.  These pre-wired and pre-piped portable water chillers require minimum installation effort while occupying a small amount of floor space to save installation time and money.
