DualCore™ Series Carbon Steel Expansion Tank with Built-in Rubber Bladder
The DualCore™ series of pressure tanks, independently developed by Influx (Danyang) Technology Co. Ltd., uses an all-in-one manufacturing process for both the tank body and built-in bladders as its key advantage, completely avoiding the compatibility risks and supply chain fluctuations of the traditional OEM model.
The product strictly meets DIRECTIVE 2014/68/EU and the EN13831:2007 standard. Its 10~16 bar high-pressure design and a wide volume range of 100L to 10,000L makes it ideal for stable water supply in high-rise buildings, industrial circulation systems, and other demanding scenarios.
The replaceable bladder and built-in high-precision pressure gauge further enhance user experience - the bladder can be quickly replaced to extend the tank's life. In contrast, real-time pressure monitoring boosts operation and maintenance efficiency, setting a technical benchmark for reliable water supply from production to service.
