Characteristics 2.1 Variety of Options Piston type 2 compressor parallel unit Piston type 3 compressor parallel unit Piston type 4 compressor parallel unit These units support multiple refrigerants including R404a, R507, R407C, and R22. 2.2 Stable & Reliable Equipped with high-quality compressors from renowned brands, these units follow the latest design standards, offering a safe and reliable system. Standard controller prevents frequent motor on/off and includes safety protection modules like phase loss protector, inverted sequence, overvoltage protector, undervoltage protector, oil pressure, high pressure, low pressure, and motor overload. 2.3 High Efficiency & Energy Saving Due to seasonal variations in refrigeration demand, the unit has advanced control systems to maintain high efficiency. The average parallel unit efficiency is 30% higher than single compressor units. Multiple compressor parallel units allow for multi-level energy control, dynamically adjusting refrigeration output based on actual needs. High-efficiency oil separators ensure minimal lubricant enters the system, enhancing heat exchange efficiency. 2.4 Compact & Nimble Components such as compressors, reservoirs, gas-liquid separators, oil separators, and electrical control equipment are all centralized, maximizing space utilization. The compact structure saves assembly space, benefiting commercial use and providing additional profit for end users. 3.
