Package chillers
A complete package chiller will include compressor, condenser, evap-
orator (chiller), internal piping, and operating and capacity controls.
Controls should be in a panel and include all internal wiring with a
terminal strip for external wiring connections. In small packages—up
to about 250 tons—motor starters are usually included. In larger chill-
ers, unit-mounted starters are an option. Some units with air-cooled
condensers are designed for outdoor mounting; freeze prevention pro-
cedures must be followed. Units with water-cooled condensers require
an external source of condensing water.
Chillers with reciprocating compressors are found mostly in the 5-
to 200-ton range. Although larger units are made, economics usually
