Cooling capacity: 335-1300kW

In commercial buildings, hospitals, factories, governmental institutions, sports stadiums, schools and so on, Carrier’s 30HXY/30HXC provides satisfactory air-conditioning, and with the premium quality, pioneering environmental concept, highly efficient operation and the perfect after-sale services, it has become one of the most popular series in Carrier air-conditioner family.

Fully adopting the environmentally friendly refrigerant – HFC134-a, 30HXC Screw Chiller has been through the test for years in the market and become a mature product, environmentally friendly, energy saving, convenient and quiet, with wide range of applications, which won the high praise of customers and represents the world –leading level of the modern water-cooled screw chiller.

30HXC High Efficiency Water-cooled Screw Chiller further improves the heat transfer and optimizes the system based on the standard unit, to realize higher full load/part load efficiency. It is highly efficient, energy saving, reliable in operation and convenient for maintenance, and it considers both the full load and the part load, in particular, the outstanding comprehensive part load performance, to provide the more economic unit for users.

Stable and Highly Efficient

• High precision manufacture process
  Adopting the high accuracy male/female rotor, with the accuracy of micrometer level, stable operation and low vibration, to ensure the high efficiency and reliable operation.
• 06N compressor
  The new generation Carrier 06N screw compressor is a semi-closed screw compressor specially designed for HFC-134a, manufactured with exquisite and advanced techniques. The unique plunger energy adjustment and the oil pump lubrication system can reduce the energy consumption and generate the stable and reliable operation.
• Carrier Patent – Electronic Expansion Valve
  The Carrier patented Level 1500 high precision electronic expansion valve combines the rough and fine adjustment to eliminate the heat power delay of the heat expansion valve. It can choke flow and reduce pressure, adjust the flow and control the liquid level, to make prompt and accurate control of the evaporating temperature and effectively improve the operating efficiency of the low load condition
• Highly Efficient Flooded Evaporator
  The heat transfer copper tube can be fully immersed in the refrigerating liquid to achieve the better transfer effect, make the tube side cleaning simple, and the use more reliable and the maintenance more convenient.
• TURBO-B Carrier Patented Super High Efficiency Heat Transfer Tube
  The super high efficiency evaporating tube is designed with the special heat transfer surface based on the leading technology of Carrier aiming at different heat transfer mechanism and the fluid medium, to optimize the transfer efficiency, reduce the loss of flow pressure along the process and decrease the energy consumption.

New Environmental Friendly Refrigerant

• The environmentally friendly refrigerant HFC-134a brings no damage to the ozone sphere
  The dissipation of the ozone sphere can cause skin cancer, cataract and other diseases, reduce the agricultural output, damage the ocean ecosystem and reduce the fishery output. HFC-134a is recognized as the best environmental-friendly refrigerant, widely used in the world, with the increasingly wider applications and rise in performance-price ratio.
• Professional design dedicated for HFC-134a
  The chiller is specially designed for HFC-134a, perfectly integrating the environmen- tal considerations and high efficiency. It is a trustworthy product with mature techniques.

Quiet Operation from 3-stage Silencing

1. Specially designed built-in compressor silencer
   To reasonably guide the exhaust flow and effectively reduce the noises produced from pulsation of high pressure exhaust air flow.
   
   
2. New external silencer of compressor
   The silencer on each compressor exhaust line can transform large portion of sound energy into heat energy with the advance sound absorption material, to significantly reduce the noise of the chiller.
   
   
3. Tailored chiller silencing cabinet
   The 2nd generation silencing cabinet features the pretty appearance, flexible and compact structure and better silencing effect.

Convenient Installation and Operation

• Compact body to enter the standard door easily
  It can easily pass the standard door, convenient for the on-site installation.
  All the chillers are less than 1050mm wide.
• Simply connect the water and power line to complete the installation
  The installation is very convenient, as the refrigerant has been filled before ex-factory, the installation at the site is just to connect it to the water line and the power line. Electrical connection: 380V – 3ph – 50Hz Water connection: connected to the refrigerated and cooled water lines The new clip water chamber for connecting with the tube simplifies the installation procedures and improves the reliability.
• Visualized interface
  Pro-Dialog plus computer control system and the visualized interface show you the operation procedure at a glance.
