Abstract
A centrifugal chiller includes both a unit-mounted full-voltage starter and a unit-mounted reduced-voltage starter. The chiller is rather large with a rated cooling capacity of at least 300 tons and is driven by a motor that is powered by at least 2,000 volts. The chiller includes an evaporator shell and a condenser shell in a staggered arrangement to provide a combined height of between 6 and 12 feet and a combined width of between 5 and 8.5 feet. The staggered arrangement of the shells plus mounting the two starters at opposite sides of the motor provide a chiller whose outer dimensions permit the chiller to be shipped as a single package without exceeding certain shipping limits.
