A retrofit system that converts truck engine waste heat into clean electricity for refrigerated trailers, with no second diesel tank, no extra emissions.



Reefer Cooling – Reimagined
We recover energy that’s normally lost through exhaust, converting up to 66% of engine heat into usable power.
Our engineered system transforms that heat into electricity that can run refrigeration units, mixers, lights, or other systems.
Our compact solution fits most Class 8 trucks with no major modifications, keeping downtime low and savings high.
Our technology delivers immediate financial returns while helping your fleet meet sustainability goals.
Each system is engineered for seamless integration into core industries where efficiency, emissions, and uptime matter most.

REEFERS' system recovers waste heat from diesel engines and uses it to power refrigeration units without burning additional fuel.

Concrete mixers require constant energy to keep the drum rotating often through fuel-hungry idling.

At data center's, construction sites, remote operations, or critical infrastructure zones, diesel generators work hard and waste a lot of heat.
Start a Simulation where you can calculate what you could be saving.
At REEFERS, we design simple, smart systems that turn waste heat into usable power. Our mission is to reduce fuel costs, lower emissions, and enhance energy efficiency for refrigerated trucks and beyond.
To revolutionize energy efficiency in transportation and heavy machinery by recovering waste heat and transforming it into usable energy, reducing fuel consumption and greenhouse gas emissions while providing economic benefits to our customers.
