Our Zero-emission eTRU Solutions
The Er-230 and ER-460 are all-electric stationary refrigeration units for the cold storage industry. The are installed in remanufactured frame and coil set systems with all new electrical and refrigeration, and feature a scroll compressor, fan motor, and controls using three-phase power and R40A refrigerant for cooling and heating. The ER-230 runs on 230 VAC power, the ER-460 runs on 460 VAC power.
In short, the ER-230 and ER-460 are reliable, quite, efficient, high-capacity, zero-emissions, low-maintenance cold storage solutions.
Features

Grocery & Food Distribution
Stores and distribution centers need reliable cold storage for perishable items like dairy, produce, and frozen foods.
Pharmaceutical & Healthcare
Temperature-controlled storage is critical for vaccines, medications, and medical supplies.
Agriculture & Produce Growers
Farmers store harvested fruits and vegetables to maintain freshness before shipping to market.
Logistics & 3PL Warehousing
Third-party logistics providers use cold storage containers or facilities to support cold chain distribution.
CARB Compliant & Reliable
California Air Resources Board (CARB) that limit emissions from transport refrigeration units (TRUs). Electric reefers meet these standards by operating with zero diesel emissions, helping fleets reduce pollution while complying with strict environmental regulations. Because they run on electric power instead of diesel engines, electric reefers provide a cleaner and more sustainable refrigeration solution for refrigerated transport and stationary cold storage

Category FAQ
What type of controls do the ER-230 and ER-460 have, and are they easy to use?
Safe, easy, low-voltage (24V) commercial-style controls are used. Units are well marked, and there is ample support documentation avalaible.
How well do the ER-230 and 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-230 and ER-460?
The units are designed to be “voltage tolerant.” ER-230s run on a range from 208V – 240V. 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-230s we recommend a 60A service with a continuous running supply of 30A. For ER-460s we recommend a 30A service with a continuous running supply of 15A.
