Back 60 years ago, Thailand started exporting processed foods this year. In 1967, the government's industrial revitalization policy produced and exported. Since then, the food preservation industry in the form of cold storage has developed rapidly. At present, the cold storage business has undergone great changes with the changes in social food patterns. Transformation into ready-to-eat products (RTE and RTD): ready-to-eat, ready-to-drink) more, requiring cold storage during production and distribution. According to statistics from the Ministry of Commerce, the number of cold storage in Thailand has reached more than 100 operators, and the country has a storage capacity of more than 600,000 tons. There is also an ice-making industry, in addition to being consumed, it is also an important link for small entrepreneurs to keep food fresh.

PTT provides high-quality refrigeration compressor lubricants, which can be selected according to the operating temperature. The lowest operating and refrigerant type (refrigerator) used from HIFREEZE A is made from paraffin base oil. A (paraffin) is suitable for refrigeration systems and ice factories that use ammonia (ammonia, NH 3,-[R-717) or hydrocarbons (hydrocarbons) as refrigerants to make ice in accordance with DIN standards. 51503KAA and KE can be used at temperatures up to -42 degrees Celsius by lubricating various moving parts of the compressor, such as bearing rings and piston cylinders.

Additional advice: If you have ever used refrigeration compressor oil naphthenic (naphthenic acid) before being converted to paraffin product HIFREEZE A (paraffin), the service life of the oil filter may be shortened due to paraffin oil. Phoenix will wash away the old, worn, turbid naphthenic oil, which may find excess oil flowing back from the evaporator, causing the engine to stop. Work due to high oil level, can be repaired by removing excess oil in the compressor

HIFREEZEř refrigeration compressor lubricating oil is made of naphthenic base oil. (Naphthenic acid) is of good quality, has excellent antioxidant properties, and can be used for machines that have no chance of direct contact with food (NSF) H2 registration) for the use of ammonia (ammonia, NH 3,-[R-717) or Freon R -22 as the refrigeration system of the refrigerant.

At present, it mainly produces air conditioners and refrigerators. Including almost all refrigeration and air-conditioning system installers have switched to refrigerants. (Refrigerant) type (hydrofluorocarbon) such as-[R-32, R-410A, R-404A, R-134A, etc. Alternative refrigerant type HCFC (fluorochlorocarbon halogen). -[R-22. Import prohibition Finally, HIFREEZE SYN-PE is a lubricant for refrigeration compressors. Made of synthetic grade (POE base oil) with absolute chemical stability, high quality, very suitable for lubricating HFC refrigeration compressors ([R-134一, R-404一, R-407C, R-410一, R-507 ) As a refrigerant. Cold-resistant, environmentally friendly, in line with DIN 51503 KD standard.

Note: Synthetic POE oil should not be used in ammonia-based refrigeration systems. Due to the reaction between the refrigerant POE and ammonia will produce types of compounds that will damage the system. Can be cooled
