Piston-type - Single-stage Parallel (20HP～350HP), Evaporation temperature 7.5℃～-45℃.
Stable and Reliable Operation
● Utilizes internationally renowned high-quality brand compressors and components, adhering to advanced foreign design concepts, perfectly integrated into a safe and reliable system.
● Each unit is factory-equipped with a full set of safety protection modules including phase loss, reverse phase sequence, overvoltage, undervoltage, oil pressure, high pressure, low pressure, and motor overload, as well as controls that effectively avoid frequent start-stop cycles.
● Each unit is factory-equipped with a PLC controller, which automatically adjusts the number of compressors in operation based on cooling demand, balances the operating time of individual compressors, reduces energy consumption, and extends the unit's lifespan by over 30% compared to single-compressor units.
● Unique low ambient condensing pressure constant regulation system prevents insufficient liquid supply or oil flow alarms in low ambient temperatures, ensuring stable system operation.
● High-efficiency gas-liquid separation device and unique pipeline design minimize the risk of compressor liquid slugging.
● Equipped with a pressure vessel-certified liquid receiver and a standard safety relief valve.
● Includes fault isolation devices; if one compressor fails, others continue to operate normally, ensuring uninterrupted customer use.
High Efficiency and Energy Saving
● Due to significant variations in cooling demand across different seasons, the unit features high capacity control to maintain efficient operation in response to load fluctuations. The average efficiency of parallel units is 30% higher than that of single-compressor units, depending on the refrigeration system.
● Multiple compressor heads operating in parallel provide multi-stage energy regulation, allowing cooling output to dynamically and smoothly match actual usage loads.
● High-efficiency oil separators ensure minimal lubricant enters the system, further enhancing heat exchanger efficiency.
● The PLC controller adjusts the number of operating compressors based on suction pressure, maintaining optimal efficiency even under partial loads.
● The PLC controller can be programmed with optimal operating curves (peak and off-peak grid periods), saving significant energy for end-users.
● Offers a "modular" installation concept, reducing on-site construction risks, shortening construction cycles, and improving product quality controllability.
Compact and Flexible Structure
● Compressors, liquid receivers, gas-liquid separators, oil separators, economizers, suction headers, liquid supply headers, and electrical control equipment are all integrated, significantly saving equipment room space.
● The compact unit structure reduces installation space, providing users with more commercial space and creating additional value for end-users.
Simple and Convenient Operation
● PLC-based safety and automatic control, equipped with a touchscreen Chinese menu and graphical control interface for easy operation, intuitively displaying equipment operating status, data logging, parameter settings, and fault alarms.
● Remote communication interfaces are reserved for convenient remote monitoring by customers.
● Equipped with a print output port for printing unit and system operation history records.
