    Hydromatic I 2 Stage Control Board

    This is a favorite of professional and private captains for the high end yachts they pilot. They are particularly suited to the Aqua Air and Marine Air brand of marine air conditioning chillers.

    The Hydromatic I two stage control board is the classic, legacy control system for multistage marine chillers. Used for over 20 years in luxury yachts, it has weathered hundreds of thousands of A/C starts on hundreds of marine air conditioning chillers around the world.

    The Hydromatic I stands the test of time, in large part due to its simple and robust operation.
