Born at Oak Ridge National Laboratory and supported by the NSF and DOE,
Shift has proven its technology at every step.
IHEX Module
Our IHEX module is perfectly suited for both air conditioning and process cooling applications, capable of storage temperatures from 0 to -15°C (32 to 5°F).
IHEX Systems expand cooling capabilities and benefit the bottom line
Cooling cost savings up to 70%
Efficiently storing ice slurry generates big cooling cost savings.
How IHEX innovations cut costs:
Because no ice sticks to the cold surface, IHEX systems rapidly generate ice.
By integrating IHEX into a DX (direct-expansion) configuration, we eliminate glycol from the cooling loop.
IHEX’s stored ice slurry responds to demand much more rapidly than traditional ice storage (think of a slushy versus ice cubes)
Improved chiller fleet operation during off-design conditions
A flexible, responsive IHEX module can minimize strain on the rest of the cooling system.
IHEX innovations show:
Our discharge rates outcool ice-on-coil systems by 20X, with < 1 ⁰F variation in discharge temperature across 90% depth-of-discharge, buffering rapid load swings so that the chillers don’t have to.
A consistent freezing rate across full and part-load operation allows optimization of the chiller system, unlike ice-on-coil.
Configurability for any application
Shift’s IHEX systems can be added in separate, modular increments.
IHEX offers:
- By separating the components, marginal storage costs are less than 20% of competing solutions
- IHEX modules and storage tanks can be added incrementally and independently to fit each project’s budget and timing.
Storage tanks can be sized to fit the space available.
Under the hood
Icephobic Heat Exchange (IHEX) Technology
By freezing water without it sticking to the cold surface, IHEX technology leads to a highly efficient cooling coil that generates ice slurry. The IHEX Module solves the problem of other ice thermal energy storage systems by eliminating the insulative ice layer and passively shedding slurry from the surface.
