LHE High Efficiency Central Chiller
LHE High Efficiency Central Chillers
The LHE high-efficiency central chiller is an advanced industrial process cooling system designed to reduce energy consumption by up to 60% while delivering precise process temperature control. The system continuously monitors ambient and process conditions and automatically adjusts operation for maximum efficiency. Built-in electrical, mechanical, and control redundancy helps minimize unplanned downtime and improve system reliability.
Available in single-circuit configurations from 20 to 60 tons, the LHE central chiller offers a modular, scalable design that grows with your operation. Additional units can be connected in parallel to provide up to 600 tons of cooling capacity. By controlling based on tank temperature rather than leaving fluid temperature, the system delivers more accurate cooling performance and maintains process water temperatures from 20°F to 80°F (-7°C to 26.6°C)

- The most efficient chiller of its kind.
- Rewarding its users with upwards of 60% in average energy savings compared to traditional cooling systems.
- Invest in today, expand in the future.
- Offering expansions up to 10 modules with 600 tons of cooling capacity within the same control platform.
- AEC maximizes uptime with a redundant design.
- Chillers communicate with one another to maintain desired tank temperature. Should a unit go down, the others automatically compensate to maintain the necessary process temperature.
Remote Air & Water Cooled
- Intuitive 10” Touch Screen Control – Monitor one to ten paralleled units with a large, high resolution color touch screen.
- Simple Strainer Maintenance – Cleaning is easy with the Stainless Steel Brazed Plate Evaporator. Incorporated TS Tech™ tool-less technology allows for quick access with less effort. The large surface area on the strainer also increases the time between required cleanings.
- More Accurate Temperature Control Chilling system operates based on tank temperature instead of unit leaving fluid temperature.
- Built in Auto-Redundancy & Controls Zones communicate between one another to maintain tank temperatures via Ethernet connectivity.
- Increased Energy Efficiency – Tandem Scroll Compressors with Staging Capability are managed by proprietary algorithms.
- Replaceable Filter Core – Easily replace and maintain filters without having to cut out old unit and braze in new.
- Welded Frame – Provides better structural integrity during transport & operation. The frame is powder coated for increased corrosion resistance.
Water Cooled
- Controlled to Optimize Performance The electronic water regulating valve automatically adjusts to control head pressure.
- Resistant to Corrosion Shell & Tube Condenser designed to be more resilient to clogging and easier to clean.
- Increased Stability Condenser is closer to the ground to reduce operational vibration.
Remote Air-Cooled
- Higher Performance Motors The electronically commutated (EC) brush-less motor increases reliability, controllability and energy savings.
- Robust Design Tube & Fin Condensers have a higher resistance to corrosion while providing more efficiency.
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.
