ER-460 | Electric Reefer Unit
The ER-460 is a fully electric transport refrigeration unit designed to deliver reliable, emissions-free cooling for trailers and stationary storage applications. Built for 460V three-phase power, it provides quiet operation, low maintenance, and significantly reduced operating costs compared to traditional diesel TRUs. Its durable, industrial design makes it ideal for retail, warehouse, and cold chain environments where dependable temperature control is critical.

Cost & Operational Efficiency
A zero-emission reefer eliminates diesel fuel use, reducing operating costs and protecting against fluctuating fuel prices. With fewer mechanical components than diesel units, it lowers maintenance requirements and minimizes downtime, keeping equipment running reliably.
Environmental & Workplace Benefits
Because it produces no exhaust emissions, a zero-emission reefer helps companies meet sustainability goals and comply with environmental regulations. Its quieter operation also improves working conditions for drivers and warehouse staff, especially in urban or retail environments.

Zero Emissions
ER-230 meets the toughest air quality regulations, including the TRU In-use Performance Requirements from the California Air Resources Board (CARB).
Quieter Operation
ER-230 runs much more quietly than traditional diesel units, making it well-suited for distribution centers, residential areas, and noise-sensitive environments.
No Fuel Cost
ER-230 eliminates fuel and reduces maintenance costs without sacrificing reliability or performance. It also follows a reduce-reuse-recycle approach
Your in Control
The ER-460 automatically starts and stops to maintain temperature in the cargo area, with fully adjustable temperature control across cool cycles down to -20°F
Product FAQ
How well do the ER-460 cool and heat, and what temperature ranges will they hold?
The units have a very high capacity and perform extremely well in both the cooling and heating modes. Temperature operating range is -20°F to 80°F in most cases.
What are the voltage ranges for the ER-460?
The units are designed to be “voltage tolerant.” ER-460s run on a range from 460V – 480V.
What are the electric power supply requirements and service size?
Power must be 3-Phase. (Units cannot operate on Single-Phase.) For ER-460s we recommend a 30A service with a continuous running supply of 15A.
