Factory customization 60RT 200KW-230KW Air Cooled screw chiller
This air-cooled screw chiller is specially customized for the Canadian market. The voltage is 3ph-575V-60Hz. It uses a single Hanbell closed screw compressor, high-efficiency copper tube fin condenser, and 9 large air volume units. Rotor fan, shell and tube evaporator. Environmentally friendly refrigerant, electrical appliances are high-quality ABB brand with UL certification, Siemens PLC control system, and stainless steel CNP water pump.
Air cooled screw chillers offer several advantages in industrial cooling applications:
Easy installation: Air cooled screw chillers do not require a separate cooling tower or water source, making them easier and more cost-effective to install. They can be placed directly at the site where cooling is needed.
Energy efficient: Air cooled screw chillers utilize an air-cooled condenser that transfers heat to the ambient air. This eliminates the need for water consumption and reduces the energy required for cooling. They are particularly suitable for areas with limited water availability or strict water usage regulations.
Lower operational costs: Since air cooled screw chillers do not rely on cooling towers and associated water treatment systems, they have lower maintenance and operating costs compared to water-cooled chillers. They also do not require regular monitoring of water quality or chemical treatments.
Flexibility in placement: Air cooled screw chillers can be placed indoors or outdoors, offering more flexibility in site selection. They can be installed on rooftops or in areas where water cooling is not feasible.
Suitable for variable load conditions: Air cooled screw chillers typically have a wide operating range and can handle varying cooling loads. They are equipped with multiple compressors that can modulate their capacity to match the cooling demand, resulting in energy savings during partial load conditions.
Compact design: Air cooled screw chillers are designed to be compact and space-saving. They integrate the compressor, condenser, and evaporator into a single unit, reducing the overall footprint required for installation.
Lower water consumption: As the name suggests, air cooled screw chillers use air as a cooling medium instead of water. This reduces water consumption and eliminates the need for a water treatment system, resulting in water savings.
Reliability: Air cooled screw chillers are known for their reliable operation and durability. They are designed to handle demanding industrial environments and can provide consistent cooling performance.
It is important to consider factors such as cooling capacity, efficiency, noise levels, and specific cooling requirements when selecting an air cooled screw chiller for a particular application.
Compressor features:
•New screw type compressor with 20%-30% higher in efficiency.
•Cooling capacity control available at four steps (100%-75%-50%-25%), three steps (100%-66%-33%) or no steps control system.
•High efficiency, low noise and vibration, easy to install.
•Environmental protection refrigerant R134a, R407c available.
Control operation system:
•SIEMENS PLC program control system, human-computer interface with big LED touch panel, running state displaying in multi-language, and self-diagnosis for easy operation and supervision.
•Extended industrial interface, convenient for being computer monitor via network.
Completely safety protection function:
•Multisafety protection by high and low pressure, compressor overheating, overloading, over temperature, flow switch, phase sequence, phase-missing, exhaust overheating and anti-freezing.
Air-Cooled Screw Chiller Products Information
Features:
1. The compressor adopts the international brand. The original imported international brand BITZER Germany (Bitzer) HANBELL China Taiwan (Hanbell), a new type of high-efficiency screw rotor compressor, the efficiency is 20%-30% higher than the general compressor.
2. High efficiency 5:6 patented asymmetric rotor tooth profile.
3. Capacity control can adopt four-stage (100%-75%-50%-25%) or three-stage (100%-66%-33%) and stepless control system.
4. The combined design of 11 bearings and a-type axial thrust balance drum greatly increases the bearing life by 2.5-3.5 times.
5. The use of high-efficiency silicon steel sheet special groove design, and equipped with internal and external omnidirectional design cooling channel, so that the compressor motor can play the highest efficiency under any load.
6. The unique built-in oil pressure system does not need an oil pump to ensure that the compressor maintains the best lubrication effect. The oil separator adopts a double-layer filter method, which has a good oil filtering effect and the heat exchanger can exert its maximum capacity.
7. High efficiency, low noise and low vibration.
8. A variety of refrigerants are available. In addition to R22 refrigerant, environmentally friendly refrigerants such as R134a and R407c can also be used.
