Characteristic:
● The compressor is a low-noise, high-efficiency semi-hermetic screw type with a multi-national patented 5-to-6 tooth profile design. It supports 3-stage, 4-stage or stepless capacity control, with low-capacity unloaded start to reduce grid impact. Multiple protections are included: high/low oil level sight glasses, high-efficiency oil heaters, electrical/temperature monitoring and coil overheat protection. The compressor offers good balance, low vibration, low noise, long lifespan and low energy consumption.
● High-efficiency shell-and-tube condenser with a seamless steel shell (anti-rust treated, 144PSI rated). High-efficiency seamless copper tubes with finned surfaces ensure optimal heat transfer (150PSI rated). Direct-type water pipes are easy to clean; ends are interchangeable for flexible connection directions. Multi-circuit water flow includes safety and relief valves.
● Direct-expansion shell-and-tube evaporator with a 350PSI-rated shell insulated with flame-retardant, low-thermal-conductivity material. Seamless copper refrigerant tubes with internal threaded fins enhance heat transfer (150PSI rated). Carbon steel tube sheets are securely joined to copper tubes via expansion joints. Internal baffles split refrigerant flow for proper oil return. Liquid and low-pressure lines use service valves for easy maintenance.
● Equipped with high-pressure check/expansion valves, solenoid valves, liquid line check valves, sight glasses, angle valves and filter driers. The composite evaporator features independent refrigerant circuits to prevent system imbalance. Multiple protections include high/low pressure switches, discharge temperature protection, oil pressure/temperature protection, motor overload protection, phase loss/reversal protection, safety valves and freeze protection switches.
● All electrical components are imported. The advanced touchscreen controller supports remote operation via TCP/IP communication module, enabling remote start-up and monitoring through a central computer control system.
