Committed to Quality We have always regarded quality as the basis of our success. We insist on putting quality first. We continuously strive to improve our manufacturing processes and refine our management systems. NSF grade materials provide safe storage of drinking water after filtration. To safeguard customers interests, all tanks undergo in-process and finished-product inspections. For effective quality control, all manufacturing processes are performed in-house as part of an integrated system. A range of sizes from 8 liters to 80 liters meets customers differing needs. Stainless steel connection system provides safe drinking water.
