Cut Cooling Electricity Costs by Up to 80%
Equaphase eutectic PCM cool storage systems deliver fast paybacks, cooling resiliency, and chiller-less operation for hospitals, data centers, universities, and large commercial buildings.
Charge at Night. Store at No Cost. Cool All Day.
Our eutectic phase change materials shift your cooling load to cheap off-peak hours — eliminating expensive daytime chiller operation entirely.
The chiller or cooling tower runs at night when electricity rates are lowest, freezing the PCM modules stored in your tank.
The frozen PCM holds its thermal energy — no electricity required to maintain the stored cooling capacity.
As the PCM melts, it cools your facility through existing chilled water infrastructure — eliminating peak-hour chiller operation.
Three Systems. Every Climate.
From load-shifting retrofits that work anywhere, to chiller-less operation in dry and moderate climates — there's an Equaphase system for your facility.
Paybacks That Speak for Themselves.
Real numbers from real projects. Even without cooling tower night charging, Equaphase delivers some of the fastest paybacks in the energy storage industry.
| Project | System Cost | 30% Tax Credit | Net Cost | Annual Savings | Payback |
|---|---|---|---|---|---|
| Silicon Valley Data Center1.8 MW Demand Reduction | $3,024,000 | ($907,200) | $2,116,800 | $723,308 | 2.9 years |
| Phoenix Data Center2.4 MW Demand Reduction | $3,220,000 | ($966,000) | $2,254,000 | $773,841 | 2.9 years |
| San Bernardino Office Building100,000 sq ft / 215 kW | $287,500 | ($86,500) | $201,000 | $80,927 | 2.5 years |
| Phoenix Office Building100,000 sq ft / 250 kW | $324,000 | ($97,200) | $226,800 | $79,762 | 2.8 years |
* Savings from peak demand reduction and load shifting. No cooling tower night charging assumed. With cooling tower charging in suitable climates, paybacks can drop to under 2 years.
The 30% Federal Tax Credit Is Still Available.
Investment Tax Credit
on total system cost
Inflation Reduction Act — Energy Storage Technology
The IRA's Clean Electricity Investment Credit explicitly includes thermal energy storage — defined as property that receives, stores, and delivers energy for use as heating or cooling.
Still Available After the One Big Beautiful Bill Act
The 30% investment tax credit for thermal energy storage was preserved. For projects of 1 MW or greater, prevailing wage labor conditions apply to receive the full credit.
Direct Impact on Your Payback Period
The 30% credit directly reduces your net system cost — further shortening an already fast payback. The combination of energy savings plus tax credit makes for a compelling financial case.
Energy Savings as a Service.
No capital required. Your facility benefits from Day 1. Our shared savings model removes the biggest barrier to adoption.
Zero Upfront Cost
Equaphase installs and finances the entire system. Your facility pays nothing to get started.
Equaphase Retains Ownership
We retain system ownership and capture the associated federal tax credits.
Split the Savings
Your facility and Equaphase share electricity cost savings equally over a defined agreement term.
You Own It at the End
Full system ownership transfers to your facility at the conclusion of the agreement.
Example: San Bernardino Office Building
100,000 sq ft | 850 ton-hour cooling system
| Facility | Equaphase | |
|---|---|---|
| Installation | $0 | $0 |
| Savings (Year 1) | $26,000 | $26,000 |
| Savings (Yrs 2–10)* | $284,618 | $284,618 |
| Tax Credits | $0 | $59,925 |
| 10-Year Total | $310,618 + system ownership | $370,543 |
* Assumes 5% annual increase in electricity rates.
Proven at Scale, for Decades.
Over 90 major installations worldwide, with systems operating continuously for 30+ years. No other PCM cool storage provider has a comparable track record.
