120℃ Medium-Temperature Phase-Change Thermal Battery

Based on its proprietary high energy storage density and stable phase-change materials, HeatMate has developed an efficient phase-change thermal battery. This battery collects and stores low-cost, intermittent energy sources such as off-peak electricity, solar energy, and industrial waste heat, and releases them in a controlled manner. It is widely used in clean heating, hot-water supply, grid peak regulation, and photovoltaic and solar thermal energy utilization.

Parameters

Equipment lifespan exceeds 20 years.

Green, Safe, and Environmentally Friendly

Operates at atmospheric pressure, no harmful emissions, non-flammable, recyclable.

High Charge and Discharge Efficiency

Charging in 6 to 8 hours, efficiency >95%, less than 5% heat loss after 24 hours of standing.

Heat storage/Heating systems

01 Medium-Temperature Thermal Battery

Phase-change thermal battery are modularly installed to form thermal storage systems that store different energy sources in the form of heat.

02 Heat Source Equipment

Commonly used heat source equipment including thermal oil boilers, solar collectors, medium temperature waste heat boiler, etc.; converting different forms of energy into heat.

03 Circulation Pumps

Circulation pumps circulate the working medium (water or thermal oil) to transfer heat from the heat source equipment to the thermal battery or the user end.

04 Heat Exchangers

Heat exchangers are often plate heat exchangers or volumetric heat exchangers, which transfer heat from the first network to the second network.

05 Intelligent Control System

Intelligent control system realizes the switching of the system's charging and discharging modes and provides heat through the pipeline electric valve.

Operation mode

Heat Charging

Heat is stored in the phase-change thermal battery by utilizing cheap energy such as valley electricity, solar energy, and waste heat.

Heat Release

Release the heat stored in the thermal battery; reduce the use of high-priced energy,reduce operating costs, and realize low-carbon or zero-carbon heat supply.
