Refrigeration Parts Solution supplies both air-cooled and water-cooled condensers and evaporators. Most coils can be used as either an evaporator or condenser. If you are designing your own system and are unsure of how to size these parts, we strongly suggest that you purchase one of our technical books for guidance. No matter what system you own or wish to build, an RParts heat exchanger will provide the performance you need. Replacing one on an existing system? Our air-cooled coils, shell-in-tube and tube-in-tube units are all guaranteed to meet or exceed the quality of the original equipment. In many cases your RParts component is actually manufactured for us by the very same company that made your original OEM part. You'll get the same part at a fraction of the cost!
