Open industrial chiller

Open type chillers belong to an open structure, with similar configuration and appearance to screw chillers, but with different compressor types. Open chillers use scroll compressors or piston compressors, while screw chillers use screw compressors. This type of chiller has a simple structure, low cost, and easy maintenance in the later stage, so it is very popular among users.

1. Compressor

The open type chiller adopts internationally renowned brand compressors: Daikin from Japan, Danfoss from Denmark, Gulun from the United States, Hanzhong from Taiwan, Bitzer from Germany, etc. Each compressor comes with an independent refrigeration circuit, where the evaporator and condenser are also completely independent. All compressors are commanded by a unified microcomputer control system, and are turned on and off one by one without interfering with each other. They are equipped with high-quality and efficient copper tube condensers and world-renowned brand components, making the open type chiller have the advantages of small size, low noise, high energy, long service life, and easy operation. Its beautiful and exquisite appearance design and reliable and stable high-performance quality are outstanding among similar products!

2. The evaporator copper tube of the open type chiller adopts an internally and externally threaded reinforced tube. The surface of the copper tube has threads, the outer surface of the copper tube is smooth, and the cooling effect is good. The evaporator cylinder is insulated with a 25mm thick PE insulation board, which does not condense and reduces the loss of cooling capacity.

3. Condenser

The condenser of the open type chiller adopts copper pipes imported from abroad, processed into trapezoidal low rib pipes to enhance heat transfer ability. The surface of the copper pipes is smooth, reducing water pressure and making it easy to clean and maintain.

4. Protective device

The protection system devices of an open type chiller include: compressor delay start protector, overload protector, high and low pressure protector, temperature control switch, antifreeze switch, fuse plug, electronic time protection safety valve, compressor overheat protector, compressor frequent start protector, and abnormal indicator light to ensure the normal operation of the unit.

5. Control system

The highly intelligent PLC and PC level computer control system developed by the open chiller selection company can be used for remote monitoring and control, with multiple functions such as automatic loading and unloading, timed on-off, and recording of fault causes; Easy to operate, connect the host to the power supply. Low failure rate, high safety factor, simple installation, system control can be adjusted in real time, intuitive and reliable.

6. Freezing accessories

The refrigeration components of the open chiller are all selected from top global brands such as SPORLAN (Poland, USA), ALCO (Alco, USA), DANFOSS (Danfoss, Denmark), etc., with excellent performance, safety and environmental protection.
