AEC’s Trident GS Series utilizes dual screw-compressor technology while offering an advanced operator panel for intuitive process chilling system control. Individual circuits range from 50 to 120 tons of chilling capacity, and users have the ability to parallel up to five circuits for a maximum of 600 tons of chilling capacity. Its integrated toolless strainer technology allows for rapid maintenance while maximizing the uptime of each chiller circuit. The central chiller’s electronic sensors with digital readout include leaving and entering fluid temperatures; compressor suction pressure; compressor discharge pressure; condenser inlet temperature; superheat; subcool; pump pressure and tank level. The modular central chiller is available in air- or water-cooled models. Features include semi-hermetic dual screw with crank case heaters, pressure sensors and high and low refrigerant pressure sensors; stainless steel, copper-brazed plate evaporator; toolless evaporator backflush connections, evaporator inlet strainer, and strainer blowdown valve; fully insulated refrigeration and process piping; and nonferrous construction on chilled-water side.
