Typically, free cooling is possible with installing a gasketed plate heat exchanger between the cooling tower and the chiller condenser. This system has many advantages, in protecting the chiller condenser and improving chiller efficiency, saving electricity and reducing maintenance costs of your condenser.

An alternative SIMPLE installation looks like this:
- During summer the Gasketed PHE is not in operation, chiller operates as normal.
- During winter the chiller is turned off and bypassed. The piping is just tapping on to the cooling tower and the chilled water lines. No complicated automation, the system works ON/OFF.

The Alfa Laval gasketed plate heat exchanger can deliver cold water to the point of need 1°C above that of cooling tower water.
