Trident™ GS Series

Trident™ GS Series Central Chillers

The Trident™ GS Series Modular Central Chiller integrates advanced technologies with proven component design to offer a capable and innovative process chilling solution, with a leaving fluid temperature range of 30°F to 65°F (-1°C to 18°C).

The state-of-the-art controls provide the operator with intuitive command structures while offering critical unit performance data in understandable dashboard sets. Individual circuit capabilities range from 50 tons to 120 tons of cooling capacity. Each circuit has the ability to parallel with other Trident™ circuits of the same size for maximum system scalability. Drone circuits offer market leading connectivity, as every unit has the same control set. This allows Trident™ to offer the ultimate plug-and-play capability currently available and can even integrate with AEC pump tanks.

Reliable and versatile chilling technology to meet the needs of today's complex processes.
  • Compact Size: The Trident™ provides maximum chilling capacity in a space-saving package.
  • Robust Capability: Intuitive controls allow for simple operation and straightforward scalability.
  • Innovative Technology: Maximizing efficiencies through intelligent design, advanced connectivity controls, and virtually effortless maintenance.
