Screw-Type Water Cooled Chiller Unit
- product brand:HEINYU HITAWIR HYC
- Numéro de stand：W4B04
- product specification:Cooling capacity: 180-2167kW
- product category:Refrigeration Equipment-Refrigeration systems and plants-Chillers, liquid
- product introduction:① High efficiency compressor
Using efficient 5:6 patented asymmetric tooth shape, higher volumetric efficiency; Equipped with the latest design motor, higher efficiency and power factor; It can realize stepless adjustment of the slide valve and greatly improve the efficiency of some loads. The precision machined semi-closed compressor rotor is corrected by dynamic balance, which has small vibration and long life. Low temperature refrigerant gas is preferred to cool the motor, effectively improving the working conditions of the motor.
② Efficient heat exchange tube
The use of efficient heat exchange tube, low phosphorus P1 material, so that the heat transfer coefficient is greatly improved, advanced tube expansion technology, so that the structural seal is more reliable, avoid mutual penetration.
③ Stable and reliable
Built-in two-stage high-efficiency oil separator, the amount of lubricating oil in the heat exchanger is greatly reduced, and the heat transfer efficiency is increased by 3% to 5%; Advanced oil return technology greatly reduces the risk of oil shortage. The main and auxiliary machines automatically balance operation, according to the accumulated running time of the compressor recorded by the microcomputer controller, determine the host, balance the running time of the compressor, and delay the service life of the whole machine.
④ Easy to debug and install
Each unit is tested in standard working conditions before leaving the factory to ensure the quality of the unit and reduce the time of field commissioning; The unit has been injected refrigerant before leaving the factory, just connect the water pipe and power supply, you can debug and run, very simple; The main parts of the unit are bolted, easy to disassemble and assemble, and can achieve separate transportation according to customer requirements.
⑤ Wide range of application
It is widely used in various commercial and industrial production processes and ice storage and other places.
⑥ Humanized operation interface
Touch operation, simple and easy to understand menu; Provide local, remote control (on-line) and network three operation control modes; The control system is equipped with RS485 standard serial communication interface, which is used for remote or special diagnostic tool analysis and judgment.
⑦ Advanced control functions
The start-stop control mode of the unit includes on-site control, remote control and schedule control, and the user can timing and remote control the start-stop of the unit. Pump interlock function to ensure the safe and stable operation of the unit; Advanced control logic to provide accurate energy regulation and safety control mode.
⑧ Perfect protection function
The use of accounts has multiple levels to prevent damage to the unit due to improper operation; Multiple protection functions: current limiting unloading and high pressure unloading functions to prevent frequent shutdown due to such failures and ensure long-term operation of the unit; Restart delay function: prevent the compressor from starting frequently, extend the service life of the unit; Other protection functions: cold water outlet low temperature, high and low pressure protection, exhaust high temperature protection, oil level protection, oil pressure differential protection, motor protection, voltage protection, flow protection, etc.
⑨25 years of producting history; for OEM/ODM products.
