R- Closed Loop Chillers
Self-Contained Recirculating Chillers
Closed-Loop chillers recirculate coolant from a tank mounted on board the chiller, through a sealed coolant loop and heat source (process) and back to the tank. The tank, pump, and evaporator are all on board the chiller.

IL- In-Line Chillers
Installed "In-Line" Where the Process Already Contains a Pump
In-Line chillers cool fluid that is passing through under pressure. Only the evaporator is in the chillers. Both the pump and tank are remote.
These chillers are often used in applications where it is advantageous to have the pump mounted on or near the tank to recirculate fluid through the chiller and back to the tank.
