IsoTES® Technology
Revolutionary single-tank thermal energy storage with constant-temperature output
What is IsoTES®?
Isothermal Thermal Energy Storage
IsoTES® is a single-tank thermal energy storage system that delivers constant-temperature output throughout the entire discharge cycle, unlike conventional two-tank systems.
Constant Temperature
Maintains consistent output temperature throughout discharge
Single Tank
Eliminates the need for separate hot and cold tanks
High Efficiency
95%+ round-trip efficiency with minimal thermal losses
Thermal Piston
Revolutionary thermal stratification mechanism
How It Works
The Thermal Piston Effect
IsoTES® achieves constant-temperature output from a single tank through our dynamic thermal piston technology.
Cellular Structure
The tank is divided into multiple Cells, allowing precise control over internal temperature distribution.
Step-Like Distribution
Distinct thermal zones are maintained, creating a sharp boundary between hot and cold areas.
Dynamic Piston Action
The stratification boundary shifts like a piston during charge/discharge, pushing constant-temperature heat out.
IsoTES® Types
Three configurations for different applications
HTS
IsoTES®Horizontal Thermal Stratification
Uses an external circulation loop between the tank and heat exchangers. The thermal piston moves horizontally based on charging depth.
