First, the quality must be guaranteed
1. Look at the appearance. The smoother and more beautiful the product is, the higher the precision of the mold used in the white iron ventilation project. Although a good-looking product is not necessarily high-quality, a high-quality product must be good-looking. Therefore, when purchasing, we can touch the shell of the device with our hands to see if there are scratches, uneven surface, deformation, etc.; or if there is uneven distribution of pigments, spots, aerosols, bubbles and other defects; Outside the plastic case,

Stainless steel is also one of the good choices. In today’s business environment, a product that is unwilling to put effort into appearance can never be made into a product with guaranteed quality. 2. Look at the craftsmanship. The reason why German machinery and equipment is famous all over the world is precisely because of its sophisticated production technology. The production and processing technology is not only directly reflected in the operation status of the product, but also shows the working attitude and style of an enterprise, and the advanced level of equipment. When purchasing products, readers can check whether the joints are tightly connected, whether the screws, buttons and other small parts used are delicately made, whether the installation is tight, whether the contact is good, and so on.

Second, the service should be warm and timely

The best products cannot always run without faults. Good after-sales service is the most effective means to relieve worries. Although it is difficult to see the after-sales service personnel of the manufacturer at the purchase site, it is a simple and effective method to see the service from the salesman. Enterprises with independent R&D and production generally have no technical problems in after-sales service. Therefore, the service attitude is the most important.

An enterprise will fully implement its business philosophy and corporate culture into the work of each employee. For a company with a warm attitude, full of energy, and professional use of words, its internal management must be strict and effective. Similarly, his after-sales service personnel must be of high quality, and the service content is followed up in a timely manner.
Third, the brand must be well-known

The brand is based on the perfect combination of product quality and manufacturer’s promotion. At the same time, manufacturers with strong brand awareness generally have long-term strategic plans, and there will be no phenomenon of making this product today and disappearing tomorrow. Therefore, I personally think that the purchase of brand-name products is preferred. If the products of brand-name companies cannot be guaranteed, there is no reason for us to trust non-brand-name products. Pay more attention to media reports and evaluations before purchasing products; such as professional magazines, exhibitions, Internet and so on. In addition, the product must be affixed with the “CCC” mark of national compulsory certification. Products without this license mark are not allowed to circulate in the market. Enterprises with strict management will also pass the ISO9000 series and other international general quality system certification. Experts’ evaluation of products, honorary titles issued by government departments, etc. can also be taken into consideration. Certification from government agencies at least shows that the company has been recognized in a certain area, and its scale is definitely much better than a company with nothing.
Fourth, the price should be reasonable

As for the price, I don’t think it’s just the price of the product, but more about how much you plan to spend on the device. At present, there are nearly ten manufacturers of evaporative refrigeration and air-conditioning equipment in the market. The competition is fierce and the price is relatively transparent. Therefore, the price difference of products of the same grade will not be very large. On the contrary, if a product is too cheap, it deserves attention. After all, the introduction of production equipment, the procurement of accessories and materials, the cost of operation and management, etc. are all established with money, and no manufacturer will do business at a loss.
Fifth, the selection should be appropriate

The purchase of evaporative air conditioners is basically the same as the purchase of other traditional air conditioners: you should choose the appropriate model. White iron ventilation project

Evaporative air conditioners are suitable for households, factories, shopping malls and other places that require open households, have heating equipment and high-temperature heat sources, have high air quality requirements, need rapid cooling due to crowded people, and have polluting gases or strong odors. Evaporative energy-saving White iron ventilation should fully understand the actual situation of the air conditioner installation site, such as the name, location, and structure of the installation site; and then choose according to the performance characteristics of different types of air conditioners (such as air volume, air supply distance, external dimensions, etc.) combined with the actual situation on the site. If you choose too small, the effect will not be achieved, and if you choose too large, it will cause waste.
