BUFFMAX 120A STD: ASME Certification - Buffer Tank

Optimize Any Hydronic Heating System with BuffMax® 120A by Thermo 2000

The BuffMax® 120A thermal storage tank is a high-performance ASME-certified 3-in-1 solution designed to optimize and improve the efficiency of any hydronic heating system. Acting simultaneously as a buffer tank, storage tank, and hydraulic separator, BuffMax® 120A is ideal for use with:

• Low-mass boilers

• Biomass heating systems

• Geothermal systems

• Heat pump systems

• Multi-zone hydronic systems

• Solar thermal energy systems

🔋 Buffer Tank – Reduce Short Cycling & Maximize Boiler Efficiency
In hydronic systems, short cycling occurs when the system load is lower than the energy source's minimum capacity—leading to frequent on/off cycles, premature equipment wear, and energy waste. The BuffMax® 120A buffer tank increases runtime efficiency and prevents these short cycles, extending the lifespan of your heating equipment and reducing energy consumption.

Benefits:

• Prevents boiler short-cycling

• Enhances system longevity

• Maintains steady water temperatures

🌡️ Storage Tank – Store Thermal Energy Like a Battery
The BuffMax® 120A thermal storage tank acts like an energy battery—storing heat and releasing it only when needed. During low heating demand periods or when used with a low-capacity energy source (e.g. solar, geothermal), the tank helps deliver immediate thermal energy without activating the primary source.

Ideal For:

• Partial load or intermittent heat demands

• Reducing startup cycles

• Enhancing solar and renewable integration

🔄 Hydraulic Separator – Improve Pump & System Performance
By functioning as a hydraulic separator, the BuffMax® 120A improves system flow, balances circuits, and protects pumps and other components. It effectively removes air, sludge, and debris, helping maintain the efficiency and safety of the entire hydronic network.

System Optimization:

• Ensures optimal pump operation

• Removes air and impurities

• Balances flow between energy source and distribution

🌍 Compatible with a Wide Range of Hydronic Systems
BuffMax® 120A buffer tanks are highly recommended for:

• Low-mass boiler optimization

• Multi-zone hydronic heating

• Biomass boiler integration

• Solar water heating systems

• Heat pumps and geothermal systems
