Frequently Asked Questions
-
What is the main purpose of a buffer tank?
A buffer tank stores thermal energy (hot or cold) to reduce system cycling, maintain stable temperatures, and handle peak demand. It is commonly used in HVAC, solar thermal, and heat pump systems. -
Is the 500L tank insulated?
Yes, insulation is available as an option. We recommend 50mm polyurethane foam insulation for both hot and cold applications to improve efficiency and prevent condensation. -
Can I customize the inlet/outlet positions or sizes?
Absolutely. Our manufacturing process allows for custom connection sizes (e.g., 1.5", 2", 3" NPT or flanged) and additional ports such as temperature sensor wells, drain valves, or air vents. Please contact us with your requirements. -
What is the maximum working pressure?
The standard design pressure is 0.6 MPa (6 bar). For higher pressure applications, we can manufacture tanks up to 1.0 MPa (10 bar) upon request. -
Do you provide a manual or installation guide?
Yes, every purchase includes a free installation guide with detailed drawings, step-by-step instructions, and safety precautions. Our technical support team is also available to assist you. -
How do you ensure the tank is free from leaks?
Each tank undergoes a hydrostatic pressure test at 1.5 times the design pressure before leaving the factory. We also inspect welds visually and with dye penetrant testing to guarantee integrity. -
Is the tank suitable for potable water?
Yes, 304 stainless steel is food-grade and safe for drinking water. The tank interior is smooth and easy to clean, making it suitable for hot water storage in residential or commercial systems. -
What is the shipping lead time?
Lead time depends on order quantity and customization. Standard 500L tanks typically ship within 15–25 working days after order confirmation. We coordinate with your preferred port and provide tracking information.
