Drake D80-344 PSG controller
PSG (Gen2) chiller control board
PSG Chiller Control Retrofit/Upgrade
NOW AVAILABLE
In 2015, PSG controls when out of business for good. For over a decade, the PSG chiller control was used in Legacy Chiller Systems, Drake Refrigeration and MANY other brands of chillers. The PSG chiller controller was manufactured on an OEM bases for Drake Refrigeration located in Bensalem PA. 

In 2014, Legacy Chiller Systems realized the need to keep the hundreds of chillers using the  PSG chiller control system running when access to replacement parts runs out.  Should a failure of a main control board, temperature sensor, pressure transducers, pressure transducer cables occur there is a good chance that factory replacement parts for the PSG chiller control system will no longer be available resulting in extended downtime as ALL components of the PSG chiller control system are OEM. 

As an alternative to investing in PSG  parts, Legacy Chiller Systems now offers a direct control retrofit (upgrade) for the PSG chiller control system that will work on Legacy Chiller Systems and Drake Refrigeration chiller manufactured from 2002 through 2015. As of 2020, the PSG retrofit (upgrade) has been a VERY popular product so inventory changes rapidly. For more information on the PSG Retrofit (upgrade) call (971)801-2742.
