Insulated Water Tank

AIX Boiler is a professional source factory of industrial equipment, specializing in stainless steel insulated water tanks and pressure insulated water tanks with strong thermal insulation performance, corrosion resistance and long service life. We support non-standard customization and direct factory supply, suitable for boiler matching, chemical industry, water supply and other scenarios.

The Aikes boiler insulated water tank operates based on the core principles of stainless steel sealed water storage, polyurethane closed-cell foam insulation, double-layer structure for constant temperature and energy saving, and pressure-resistant structure for stable operation. The equipment uses food-grade 304/316L stainless steel as the inner tank, a galvanized/stainless steel outer protective layer, and a high-density polyurethane integral foam insulation layer in between, forming a three-layer thermal structure that effectively reduces heat loss and maintains constant water temperature for 24 hours. Designed and manufactured in accordance with pressure vessel and water supply equipment specifications, the structure includes an inner tank, outer shell, insulation layer, water inlet/outlet, drain port, overflow port, level gauge port, flange connections, supports, etc. It features excellent thermal insulation, corrosion resistance, no rust, no secondary pollution, stable pressure resistance, and easy installation. This product strictly adheres to GB/T 17219 "Safety evaluation standard for drinking water distribution equipment and protective materials" and GB/T 3280 "Cold-rolled stainless steel sheets and strips". It undergoes four quality control tests: hydrostatic test, air tightness test, insulation performance test, and weld nondestructive testing, achieving a 100% factory acceptance rate. As a self-branded product of the Aikes Boiler original factory, it is fully produced in-house with no middlemen markup. It supports comprehensive non-standard customization for volume (0.5m³ to 200m³), thickness, insulation layer, and pressure rating. Widely used in industrial production, HVAC, hot water engineering, hotel water supply, photovoltaic energy storage, fire water supply, and other industries, it is the core equipment for modern industrial constant-temperature water storage.
