Nowadays, all walks of life are competitively motivated, and some businesses use the more materials to sell for less interest in order to gain profits. Sometimes we see the same items, but the prices are not the same, but only for a while. Can distinguish between good and bad, perhaps people have a psychological, the same thing is more willing to spend less to buy, but do not be petty, cheap, good things, although spending more money, but the time certainly will be longer, The purchase of refrigerated trucks must be ordered by qualified manufacturers, such as Jiangnan, I believe the brand, I believe Jiangnan.

Looking at the problems of some small-scale refrigerated trucks, it is understood that the company's sales of refrigerated trucks in the region are not very good. The main reason for the confusion in the industry is that the market is not standard. "The construction of cold chain logistics has already been mentioned, but the market, many things are not standardized." Look inside the industry. In his view, the country still lacks enough attention to cold-chain logistics, regulation and control not in place.

Like other vehicles, the production of refrigerated trucks also requires a national announcement. In the refrigerated truck industry, there are many private refitting phenomena. These small refitting factories lack high quality related procedures and production. "A lot of chassis manufacturers refrigerated truck announcement." Industry sources said that in order to promote sales, chassis manufacturers usually declare some refrigerator cars, chassis modification factory sales at the same time, allowing them to use their own refrigerated truck announcement.

"Some small factories are using some metals, some insulation materials, with engines and related components, plus refrigeration equipment that can be assembled into a refrigerated truck, with high profits. And the apparent seasonal demand for refrigerated trucks has skyrocketed in the summer. The supply of products is in short supply, many of the conversion factories are small, and even some car manufacturers are doing things,” said one industry expert.

“The wood, quality, customer service, etc. of the small conversion plant are very poor, but the price is very low. Many users are only cheap, regardless of other. This makes it illegal to transfer small conversion factories, but few companies that are officially qualified are not good. “Industrial circles say that the implementation of weak policies and regulations has made it possible for these substandard vehicles to spend money to solve the problem and have successfully registered and put into use.

The price of refrigerated trucks is determined by the configuration of refrigerated trucks. It is not a blind pursuit of prices. One penny, one bill, and all the time.

Gas-Phase Ultrasonic Cleaning Machine

The principle of gas-phase cleaning machine is as follow. When the solvent is heated, the steam forms the gas phase zone. In this area, the oil on the surface of the workpiece is dissolved and washed by steam. When the steam condenses, the dirt along with the grease falls back into the tank to become the cleaning fluid. Then, the cleaning fluid is heated and gasified into steam to clean the workpiece. This continuous cycle ensures the workpiece is always surrounded by the steam of cleaning fluid which overcomes the problem of contaminated cleaning fluid in the past common cleaning process.

Trichloro ethylene, tetrachloro ethylene, dichloromethane,  isopropyl alcohol have very good cleaning effect with high stability, long usage period when they are used as metal cleaning agent. In Heat Exchanger factories, these degreasing agents are widely applied in cleaning fins, bars, parting plates, tanks and other Heat Exchanger Parts . After these heat exchanger parts with oil stain are soaked in the cleaning agent and cleaned by supersonic, they`ll be very clean which also ensure heat exchanger with good brazing quality.
