Product Description
As a leading manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory (established in 1998) proudly presents our Stainless Steel Buffer Tank for HVAC Chilled Water Storage and Thermal Energy Systems. Designed to optimize energy efficiency and stabilize system temperatures, our buffer tanks are crafted from premium stainless steel to ensure long-term corrosion resistance and durability. With an annual export value exceeding US$5 million and serving global markets including North America, Europe, and Southeast Asia, we deliver reliable thermal storage solutions that meet the rigorous demands of commercial and industrial HVAC applications.
Our buffer tanks act as a hydraulic separator, decoupling the chiller from the system loop, reducing short cycling, and maintaining consistent chilled water temperatures. They are ideal for thermal energy storage systems, allowing excess cooling capacity to be stored during off-peak hours and released during peak demand, thereby lowering operational costs. Below we detail the key features, technical specifications, and benefits that make our buffer tanks a preferred choice for HVAC professionals.
Key Features & Technical Specifications
- Material Excellence: Constructed from high-grade stainless steel (304 or 316L), offering superior resistance to corrosion, rust, and chemical attack, ensuring a service life of over 15 years.
- Customizable Capacity: Available in standard sizes from 500 liters to 10,000 liters, with bespoke dimensions and connections available upon request to fit specific project requirements.
- Pressure & Temperature Range: Designed to withstand working pressures up to 1.6 MPa and temperatures from -20°C to 120°C, suitable for both chilled water and hot water thermal storage.

Frequently Asked Questions (FAQ)
-
Q: What is the primary function of a stainless steel buffer tank in HVAC systems?
A: It acts as a thermal storage and hydraulic separator, preventing short cycling of chillers, stabilizing system temperatures, and storing excess chilled water for later use, which improves overall energy efficiency. -
Q: Can I customize the tank capacity and connections?
A: Yes, we offer fully customizable capacities from 500L to 10,000L and connection sizes DN50 to DN200. Custom dimensions and flanges are available upon request. -
Q: Is insulation included, and what type is recommended?
A: Insulation is optional. We recommend polyurethane (PUR) or rock wool with thicknesses of 50–100mm, depending on your climate and temperature requirements. -
Q: What materials are used for the tank construction?
A: Standard material is SS304; for more corrosive environments, SS316L is available. Both offer excellent corrosion resistance and durability. -
Q: Does the tank meet any international standards?
A: Our tanks are designed to comply with ASME, PED, or other standards upon request. Please specify your required certification when ordering. -
Q: What is the typical lead time for production?
A: For standard sizes, lead time is 15–20 working days. Custom orders typically require 25–35 working days, depending on complexity. -
Q: How do you ensure product quality?
A: Every tank undergoes hydrostatic pressure testing, weld inspection, and surface finish checks. We also provide a 12-month warranty; extended warranty is available. -
Q: Can I get a sample before bulk order?
A: Yes, sample orders are accepted. However, for large customized tanks, we recommend visiting our factory or requesting a video inspection to verify quality.
