High Efficiency Central Chiller

High Efficiency Central Chillers

The High Efficiency Central Chillers are remarkably energy efficient and can save processors up to 60% in electrical costs. The system continuously measures ambient and process conditions and will adjust to operate in the most efficient manner. Designed with electrical, mechanical and control redundancy,  along with predictive analysis, downtime is virtually eliminated.

The High Efficiency Central Chiller is available in single circuits from 20 to 60 tons and is designed with modularity in mind. Users can purchase a system to meet their current process cooling needs. Expansion is made easy by plugging similar capacity units in parallel for up to 600 tons of cooling. The chillers control off the temperature of the tank and can maintain between 20°F to 80°F (-7°C to 26.6°C).

Controller Features

  • Enable or disable individual circuits or compressors.
  • Compressor hour tracking and staging to balance hours.
  • Compressor anti-cycle timer to prevent compressor short cycling.
  • High and low temperature warnings and faults.
  • High and low refrigerant suction and discharge warnings and faults to protect the compressor.

Complete System Access via Robust, Easy-To-Use Display
At the heart of the master module is an intelligent touch screen and controller.
Combined with the advanced 10” HD color display, users can easily control and
monitor the entire chiller system from one location. Rather than a basic list of
temperatures and pressures, the touch screen shows visual representation of the
status of each zone. If application parameters approach limitations, the zone will
automatically raise an alarm. If an alarm sounds, the machine will continue to operate
where possible, and custom-built software will provide guidance via ‘help’ screens.

Up to 60% More Efficient

  • High Efficiency Central Chillers VS Traditional Cooling Technologies

    AEC’s High Efficiency Central Chiller is the most efficient of its kind among chilling technologies, rewarding its users with upwards of 60% in average energy savings. A simple design makes for easy maintenance and service, saving additional time and cost. Compared to the VFD controlled compressor, the High Efficiency Chiller is much more efficient and much less complex.

  • Estimated Energy Cost Per Year

    Energy savings directly impacts the bottom line. By utilizing more efficient technologies, you can expect to see higher annual savings vs traditional cooling systems.
    The High Efficiency chiller realizes the largest savings when running between 40% - 80% of capacity. When running at the NPLV rates, the High Efficiency chiller will save up to 60% energy costs annually.
