Product Description: Duda Energy ExpTank-100VL-S 100 L/26.4 gallon Red Expansion Tank for Solar Water Heater Systems Thermal Pressure Protection

Introduction

Expansion tanks are crucial components for solar water heater systems. They play a vital role in relieving pressure build-up in closed loop systems, ensuring consistent pressure and preventing damage to the system. The Duda Energy ExpTank-100VL-S is a high-quality expansion tank designed specifically for solar water heater systems.

Main Features

The Red expansion tank is equipped with a special high temperature EPDM membrane, manufactured in Italy. This membrane is capable of withstanding the high temperatures typically encountered in solar systems, ensuring durability and longevity. The tank has a capacity of 100 liters or 26.4 gallons, making it suitable for medium-sized solar water heater systems.

Thermal Pressure Protection

One of the primary functions of the expansion tank is to relieve pressure from the piping as the working fluid in the solar system increases in temperature. This is particularly important in preventing the pressure valve from blowing out the working fluid in case of overheating or pump shutdown. The Duda Energy ExpTank-100VL-S effectively safeguards the system from such pressure-related issues.

Easy Installation

The expansion tank is designed for easy installation in solar water heater systems. It features a 1-inch NPT connection, ensuring compatibility with standard plumbing fittings. The tank is made of deep draw cold steel, providing strength and durability.

Frequently Asked Questions

1. What is the maximum fluid temperature that the expansion tank can handle?

The Duda Energy ExpTank-100VL-S is designed to withstand a maximum fluid temperature of 130°C (266°F). This makes it suitable for use in high-temperature solar water heater systems.

2. How do I determine the size of the expansion tank needed for my solar system?

The size of the expansion tank required depends on the total amount of fluid used in the closed loop system. You can refer to the chart below for common fluid volumes in solar systems. As an example, a standard 300-liter solar system with a 30 tube collector, 100 feet of 1/2″ stainless steel tubing, and a 300-liter tank (25m coil) would require at least an 8-liter expansion tank.

3. Are the membrane certifications of the expansion tank reliable?

Yes, the Duda Energy ExpTank-100VL-S has been certified by NSF51 and approved by EU and USA institutions. These certifications ensure that the membrane is hygienic and meets the necessary quality standards.

Conclusion

The Duda Energy ExpTank-100VL-S is an essential component for solar water heater systems, providing thermal pressure protection and ensuring the longevity of the system. With its high-quality construction and reliable performance, this expansion tank is a valuable addition to any solar water heating setup.
