China's refrigeration industry is developing rapidly. The installation of cold storage equipment needs to understand and pay attention to many aspects. Below we will find out the specific requirements for the installation of refrigeration equipment in cold storage .
The contents of the cold storage installation equipment are: compression refrigeration equipment with piston, screw and centrifugal refrigeration compressors as the main engine, potassium bromide absorption refrigeration unit and combined cold storage. Excluding steam injection type, ammonia-water absorption refrigeration equipment, for refrigerant, piston equipment mainly uses R717, R22, R502, R12, and screw type equipment mainly uses R717, R22. R12, centrifugal equipment mainly uses R717, R12, Rll; the installation of refrigeration equipment using other refrigerants can be carried out with reference to relevant regulations.
After the cold storage is installed, when the refrigeration unit or compressor unit exceeds the anti-rust guarantee period or there are obvious defects that need to be removed and washed, the degree of disassembly and wash should be determined according to the inspection conditions; the order of disassembly and the cleaning method are all in the equipment technical documents. Requirements shall be made in accordance with their requirements.
After the cold storage is installed, the refrigerant ammonia has a corrosive effect on both copper and copper alloys, except for phosphor bronze. In order to prevent accidents caused by material confusion during cold storage installation, it is not specified in the article. Other refrigerants have no corrosive effect on copper and copper alloys and can be applied during installation. When aluminum is used as the sealing material, it is required to use aluminum of higher purity, which refers to aluminum which has a low content of magnesium and other impurities, is not easily broken during use, and does not affect sealing performance.

Intermediate – Intermediate: A material produced during a drug substance processing step that must undergo further molecular modification or refinement to become a drug substance. Intermediates may or may not be isolated. Intermediates are the key products of the previous process of making APIs, which are different in structure from APIs.
for example:
Amoxicillin capsules are called preparations, amoxicillin is called API, and 6-APA is called intermediate.
Ceftriaxone sodium powder is called preparation, sterile ceftriaxone sodium is called API, and 7-ACA is called intermediate.
Our company specializes in providing key intermediates for various APIs
Intermediate is a very important type of fine chemical products. Its essence is a type of "semi-finished product", which is an intermediate product in the production of certain products. For example, if a product is to be produced, it can be produced from intermediates, saving costs and reducing It is widely used in the synthesis of medicines, pesticides, coatings, dyes and spices. In the field of medicine, intermediates are an important link in the industrial chain of the pharmaceutical industry. They are used for some chemical raw materials or chemical products in the process of drug synthesis. In a word, they are used to produce APIs.
