- Maximum allowable pressure on the high pressure side is 130 bar, and the maximum allowable pressure on the low pressure side is 100 bar. - The material of the body and cover of the pressure-bearing parts is ductile cast iron, and the shape and structure as well as the wall thickness are more adaptable to the strength requirements. - Burst pressure is 3 times the safety factor. - Pressure-bearing parts such as shut-off valve, sight glass, terminal board, etc. are all designed and manufactured according to relevant standards and have passed the test. - Safety valves are imported in accordance with European standards. - Valve components developed with Herbig are more reliable and efficient. - The main bearing adopts oil-free lubrication compliant material for higher reliability and smoothness. - Pistons are anodized for higher temperatures. - Bushings and tiles have been added to both the large and small ends of the connecting rods for greater wear and galling resistance. - More efficient and reliable motor design and manufacture. - The oil dump lubrication system ensures long-lasting lubrication inside the compressor under fixed frequency and variable frequency conditions. - The special design of the cylinder head and discharge chamber reduces heat transfer to the discharge side. - Low noise and vibration.
