The Cleanest & Cheapest kWh

The core technology behind Enjay’s offering is our breakthrough next-generation heat exchanger.
Designed specifically for contaminated industrial exhaust air, its patented architecture allows airborne particles to pass through the unit without contacting the heat transfer surfaces. This prevents fouling while maintaining operational reliability.
By combining this particle-repellent design with high energy efficiency, Enjay’s engineering team unlocked the foundation of our solution.

Nothing upfront.
Through Enjay’s Energy-as-a-Service (EaaS) model, we cover financing of the equipment, installation, and ongoing operation. You only pay for the recovered kWh — always cheaper than grid energy and at a fixed rate, protecting you from future energy price shocks.

As of March 2026, Enjay’s energy is often up to 50% cheaper than fully accounted grid-sourced energy.

Energy markets — particularly natural gas — have been highly volatile in recent years, making universal savings estimates difficult. However, Enjay delivers energy at a fixed, long-term price that is typically well below prevailing European natural gas market levels.

Because the energy is recovered and delivered on-site:

There are no transmission or distribution costs
No exposure to fuel price volatility
No combustion losses associated with gas-fired heat generation
Each recovered kWh directly replaces a purchased kWh. The result is predictable pricing, reduced energy spend, and protection against future energy price shocks.

In most cases, yes. The technology works in facilities where hot process exhaust air contains particles — including food production, industrial laundries, foundries, plastics, pet-food manufacturing, ovens, dryers, and other heat-intensive operations.

Installation is carried out during a planned maintenance shutdown, similar to other scheduled service activities. Enjay manages the process in close coordination with your team to ensure safe and efficient integration.

The system is designed as a bypass to the existing exhaust duct. This means that if the energy recovery unit were ever to impact operations, airflow can immediately be redirected back to the original configuration.

In practice, this ensures that production parameters remain unchanged and operational continuity is safeguarded.
