Ultra low-current problem of chiller compressor for Acrylic CNC engraving and milling machine? 2018-11-21

water chiller

S&A summarizes the common causes and solutions for the ultra low-current problem of the water chiller compressor as below:

1. Leakage of the refrigerant. Solution: Check if there is any oil stain on internal welding pipe inside the water chiller. Find and weld the leakage point and refill the refrigerant.
2. Blockage of the copper pipe. Solution: Change the copper pipe and refill the refrigerant.
3. Malfunction of the compressor. Solution: Touch and feel if the high pressure tube of the compressor is hot (hot is normal). If it isn’t hot, the compressor might malfunction due to its suction failure, which requires changing the compressor and refilling the refrigerant.
4. Low capacitance for the compressor. Solution: Check the starting capacitance by using the multi-meter. If it is low, change another starting capacitance.
In respect of production, S&A self develops multiple components, ranging from the core components, condensers to the sheet metals ,which get CE, RoHS and REACH approval with patent certificates, guaranteeing the stable cooling performance and high quality of the chillers; in respect of distribution, S&A has set up logistics warehouses in the main cities of China which conform to air transportation requirement, having greatly reduced the damage due to the long-distance logistics of the goods, and improved transport efficiency; in respect of service, S&A promises two-year warranty for its products and has a well-established service system for different stage of sales so that clients can get prompt response in a timely manner.
