Piston-type Low-Temperature Water-Cooled Chiller, Low-Temperature Chiller

Piston-type low-temperature water-cooled chiller features:

(1) The unit compressors are selected from original brand compressors such as American Copeland (Gulley), French Metro Compressor (Mayo), German Bizel (Bizer), and Taiwan (Hanbell) for high and low-temperature models.

(2) Utilizing refrigerants such as R404A, R410a, R22/R407C, R507, etc., to meet refrigeration temperature and environmental protection requirements; wider range

(3) Temperature Selection Range: Offers process refrigerants from -25℃ to -85℃ (users can choose different unit specifications with varying outlet temperatures based on their specific production requirements)

(4) Various refrigerants (cooling water) can be selected according to customer requirements, such as ethylene glycol solution, alcohol, and ternary mixed solutions of alcohols. The evaporator can also be designed to meet anti-corrosion requirements, using calcium chloride solution.

(5) Designed for 24/7 non-stop operation, it can meet the cold source requirements for various continuous production processes.

(6) Units come with self-contained water tanks and circulating pumps for cooling capacity, eliminating the need for cooling towers and cooling water pumps. Installation and maintenance are simple and convenient.

(7) Visual Microcomputer Control System: A comprehensive control system with a visual, touch-operated human-machine interface, capable of monitoring the operation status of the unit in real-time and automatically adjusting the energy output of the unit based on actual load changes. The control cabinet is pre-equipped with multiple connection points and spare connection points for user transmission lines, remote control alarm lines, and other control lines. It also features protective functions such as high compressor coil temperature, low chilled water outlet temperature, high exhaust temperature, frequent start/stop of the compressor, abnormal voltage, etc.; control functions including scheduled on/off, operation time limitation, scheduled on/off, oil pre-heating, fault self-diagnosis, and fault reset; and parameters such as compressor exhaust temperature, ambient temperature, return water temperature, and outlet water temperature.
