Heat recovery technology

Cooling systems waste heat.
We recover it.

EnGen captures the thermal energy expelled by commercial refrigeration systems and converts it directly into electricity — at the point of loss, without disruption.

The problem

A structural gap
in every cooling system.

~10–15%
of global electricity powers cooling and refrigeration.
Across residential and commercial systems.
IEA Energy Report

Rejected condenser heat is rarely reused on-site. In most systems, it simply dissipates into the environment.

Cooling systems are designed to reject heat — not reuse it. Every condenser expels a continuous, stable thermal gradient that represents recoverable energy.

The technology to capture this gradient has existed in laboratories for decades. What's been missing is a product engineered specifically for the thermal profile of commercial refrigeration — low-grade, continuous, and distributed.

Cooling systems are designed to reject heat — not reuse it.
The solution

A closed loop,
built into the system.

Designed for commercial refrigeration infrastructure.

EnGen captures the thermal gradient at the condenser boundary — the point where heat is actively expelled — and converts it directly into usable electricity.

Engineered for low-grade, continuous thermal gradients typical of commercial refrigeration, where traditional recovery systems are uneconomical.

01

Heat is expelled

Refrigeration systems continuously reject heat at the condenser. That gradient is stable, predictable, and currently wasted.

02

EnGen intercepts it

Mounted at the condenser boundary, EnGen captures the temperature differential before it dissipates into the environment.

03

Converted to electricity

Solid-state thermoelectric conversion produces usable DC power — output monitored live on the integrated display. No moving parts, no maintenance overhead.

04

The loop closes

Recovered power offsets net draw whenever a usable gradient is present.

Market Entry

Start with the
most measurable waste heat.

Commercial refrigeration runs 24/7, rejecting heat at every installation. It's the most repeatable starting point for validating recovery and scaling the same architecture across other heat-rejecting systems.

Why this market
  • 24/7 thermal output

    Continuous duty cycle — recovery opportunity is always present.

  • Standard install point

    Condenser location is consistent and accessible across sites.

  • Measurable ROI

    Savings show up directly on the electricity bill.

How the architecture scales
Commercial refrigeration
Current focus — pilots underway
Cold storage
Same architecture, larger scale
HVAC
Adjacent interface, broader install base
Industrial heat rejection
Higher gradient, higher recovery potential

We're currently running pilots with refrigeration operators. If you manage multi-site refrigeration infrastructure, we'd like to understand your installation constraints and energy profile.
