Rebound Technologies - The Future of Ice Storage: Unlocking Customer Value in Volatile Loads

← Back to News

In this month’s Coffee Break Webinar, SVL welcomed Russell Goldfarbmuren, CTO and Co-Founder of Rebound Technologies, for an exciting deep dive into the next generation of ice storage — and why it’s arriving just in time.

Russell introduced the C1 system, Rebound’s recently launched plug-and-play thermal energy storage unit designed to bring “agile cooling” to a market facing tightening demands on both sides of the HVAC equation.

  • Decarbonization and time-of-use energy rate changes
  • Volatile thermal loads
  • The need for flexible, scalable HVAC tools

Rebound’s bet? HVAC doesn’t need to adapt to these forces — it can solve them.

C1 and the Power of “Agile Cooling”

The centerpiece of the presentation was C1, Rebound’s flagship product in the HVAC space. C1 is an integrated ice storage system that includes built-in refrigeration, eliminating the need for site engineering. Their solution can deliver up to 150 tons of cooling capacity with six hours of storage — an ideal solution for medium-scale facilities like recreation centers, pools, and food processors.

What makes C1 special is its ability to deliver “agile cooling.” Unlike traditional systems that decouple energy from time, agile cooling decouples power from time. That means users can generate cooling gradually and discharge it in intense bursts — enabling rapid heat removal after events like food plant washdowns or pool usage peaks.

For example, one food processor was able to double its cooling power from 150 to 300 tons for two hours without upsizing chillers or utility gear. This shrank recovery windows and unlocked additional daily production hours — a massive ROI win.

Unpacking the Technology: A New Ice-Making Process

C1’s revolutionary potential lies in its proprietary ice maker, a technology Rebound designed from the ground up. Unlike bulky ice-on-coil systems, this ice maker produces thin, fast-growing ice using a novel oil-layer process that maximizes thermal accessibility while minimizing maintenance.

The process delivers:

  • 10x higher ice growth per surface area
  • Rapid harvesting with zero system shutdown
  • Low-pressure drop ice beds for high-flow discharge

The system is sealed, HEPA-filtered, and includes auto-cleaning cycles. Remote monitoring and diagnostic capabilities are baked in — and optional Hardware-as-a-Service models allow customers to access the tech with zero upfront capital.

Real-World Use Cases: From Pools to Data CentersRebound Technologies C1

Russell walked attendees through several compelling use cases:

  • Recreation Centers & Pools: C1’s ultra-cold coils and smart heat ratios cut moisture control loads by up to 40%. It reduces connected loads — a big win where utilities incentivize lower demand.
  • Retail Facilities in Texas: Peak demand shaving and ice discharge during high-tariff hours drove 70% energy cost reductions with <3-year payback.
  • Data Centers: C1 offers burst cooling during critical failure windows, reducing chiller needs and cutting peak demand from 13MW to 8MW.
  • Turbine Inlet Cooling: Helps utilities boost turbine efficiency during high-heat periods without investing in more generation capacity.

The Future: Small Units, Big Potential

C1 is just the beginning. Rebound is working on a broader C-series (C2, C3…) and an F-series for deep freeze and desiccant-free humidity control down to -40°F dew points — ideal for battery plants, cold storage, and IQF food processing.

Final Thoughts

Rebound Technologies’ C1 system is more than a breakthrough in ice storage — it’s a fundamental shift in how the HVAC industry can approach energy strategy, infrastructure design, and operational agility. As buildings and businesses face unprecedented challenges — from climate-driven decarbonization mandates to skyrocketing peak demand charges and increasingly volatile thermal loads — solutions like agile cooling aren’t just innovative. They’re essential.

C1 redefines the role of HVAC from a passive consumer of energy to a dynamic asset that unlocks value across the grid, the mechanical room, and the balance sheet. By decoupling cooling power from time and delivering precision-targeted bursts of capacity, C1 allows facilities to adapt in real time to fluctuating demands without sacrificing performance or overspending on oversized infrastructure.

Whether you’re operating a rec center struggling with moisture loads, a data center managing IT resiliency, or a food processing facility navigating rapid temperature swings — Rebound’s C1 offers a smarter, more scalable path forward. Plug-and-play simplicity. Lower connected loads. Cleaner energy profiles. Faster paybacks.

Let’s stop treating HVAC as a constraint and start seeing it as a tool for transformation.

                      Al Gramse

                      Vice President of SVL Service Corporation

                      Al Gramse has been in the HVAC industry for over 30 years. He began as a service technician.  Then over his career worked in technical support, building automation, then service manager prior to his current role.

                      How did Al end up in the HVAC industry?  “After high school, I took a couple years to figure out what I wanted to do.   Where I was working at the time, a grumpy old coworker, who I didn’t get along with, walked up to me and said ‘What are you doing here?  Go back to school.’”  I said, “For what?”  He said “There’s a tech school down the street.  Go down there and pick something that interests you”. Then he walked away.  That weird interaction, with someone I didn’t get along with, sent me down a 30-year path in the HVAC industry.   Never underestimate the potential of a little encouragement.   Even if it is from a strange source.

                      Al has been with SVL for 15 years and is the head of our SVL Service division. “The people here are some of the best in the industry,” Al says. “A bunch of team-oriented, knowledgeable, go-getters.” His personal mantra is “figure it out,” “Do a little fact-finding on your own. Use your own brain before you use someone else’s. But know when to ask for help.” he prescribes. “It’s amazing what you can accomplish on your own if you dig in a little bit.”

                      Outside of work, Al has lots of outdoor hobbies, including hunting, fishing, and motorcycling, though his favorite pastime is simply hanging out with family.
