Beware of cheap chillers that are not in good condition
Industrial chillers are commonly used temperature control equipment and are applied in various industries, so the requirements for their use are also different. The requirements for laser and precision instrument cooling are relatively high, while those for conventional injection molding and water tank cooling are slightly lower. Therefore, the quality of industrial chillers varies greatly. Many small factories or workshops tightly grasp the elements of quotation and use some abnormal methods to add competitiveness, such as using innovative components, reducing parts, and not undertaking after-sales service. The customer did not fully consider the purchase, only focusing on whether the industrial chiller quotation was low enough, and complained when there were doubts. So what methods do those low-priced chillers use to lower costs? What should we pay attention to when choosing industrial chillers?
1. Second hand chiller unit
There are many manufacturers who buy second-hand chillers and then use innovative methods to sell them as new chillers. A second-hand chiller may only cost a few hundred yuan, but after innovation, a machine can be sold for tens of thousands. Therefore, many unfamiliar businesses may buy innovative chillers without paying attention when buying them. Some chillers are priced so low that they cannot even afford them. These chillers are all innovative machines, and no one will do business at a loss. To distinguish when some of the core components inside these chillers were produced, it also depends on whether they have been used, and so on. Ice water machine
2. Only selling machines without after-sales service
Some people say that buying equipment means buying services. Indeed, for an industrial chiller, after-sales service is a crucial part. The chiller piping system is messy, and many questions require professional analysis and solutions. Moreover, the chiller needs to be maintained and cleaned after a certain period of operation. Without stable after-sales service, how can we ensure that the customer's chiller can operate reliably?
There are many chiller manufacturers who try various methods to sell their chillers, and quotation is the most important method. In order to compete with peers, they keep the chiller quotation very low, possibly even lower than 30% of the market quotation. They also promise to provide warranty for any doubts about the chiller. After customers buy this type of chiller, they think it is cheap, but after using it, doubts arise. It will take less than one or two months to have doubts. Those with good luck can use it for a year, but it is difficult to use it for a year. If there are doubts, they will be actively compared once or twice. After three or five times, repairs will be delayed if possible, and the trouble will continue. By the time, your production will be troublesome.
3. Cutting corners and using inferior materials
This is a common technique used by many chiller manufacturers. In order to secure orders, all equipment is labeled as high-end equipment, such as imported compressors and evaporators. To save costs, these chiller manufacturers use high-end imitation parts, such as compressors that are hundreds or thousands apart. It is important to identify whether the compressor is imported and whether the parts are produced by the original factory. After numbering, it can be found that most chillers that often require repair are related to accessory issues.
