Friga-Bohn Evaporator | 3C-E 4165 R + E1U | Commercial Unit Cooler
Product Description
The 3C-E 4165 R represents a powerful configuration within the Friga-Bohn cubic evaporator family.
- 4165: Denotes the fan and coil configuration, typically utilizing high-performance fans to ensure deep air throw across larger storage spaces.
- R: Indicates the specific fin spacing or coil density optimized for High to Medium temperature applications (standard for rapid cooling or fruit/vegetable storage).
- E1U: This designates the factory-fitted Electric Defrost system.
In the Gulf region, where ambient humidity can lead to rapid frost buildup even in medium-temperature rooms, the E1U electric defrost kit is essential. It ensures that the evaporator maintains peak efficiency by periodically clearing frost from the coil, preventing temperature fluctuations that could compromise stored products in Dubai’s busy logistics and hospitality sectors.
Key Features
- High Airflow Distribution: Designed with high-efficiency fan motors to ensure uniform temperature distribution throughout the cold room.
- Optimized Heat Exchanger: Built with internally grooved copper tubes and high-grade aluminum fins to maximize heat transfer efficiency.
- E1U Electric Defrost: Includes stainless steel armored heaters strategically placed in the coil and drain pan for reliable and fast defrost cycles.
- Clean & Hygienic Design: The casing features rounded corners and a polyester-coated galvanized steel finish, meeting strict international food safety and hygiene standards.
- Service-Friendly: Features a professional design with easy access to all internal components, including the electrical terminal block and fan motors, reducing maintenance downtime.

Frequently Asked Questions
- Q: What does the “R” signify in the model code?
- A: The “R” configuration is specifically tuned for higher thermal performance in positive temperature applications, often featuring a specific fin density for efficient heat removal.
- Q: Is the E1U defrost system necessary for chilled rooms?
- A: Yes, in high-traffic commercial cold rooms in the UAE, moisture from frequent door openings can cause icing even above 0°C. The E1U provides the necessary heat to clear this buildup quickly.
- Q: What is the benefit of the polyester coating?
- A: It provides superior resistance to corrosion (especially in saline coastal environments like Dubai) and is easy to sanitize, making it ideal for the food industry.
