Friga-Bohn Evaporator | 3C-E 3454 R + E1U | Industrial Quad-Fan Unit Cooler
Product Description
The 3C-E 3454 R is the flagship of the 300mm fan series, offering maximum coverage for wide refrigerated spaces.
- 3454: Denotes a quadruple-fan configuration (4 x 300mm motors). The “54” indicates a high-performance, deep coil block that provides exceptional heat exchange capacity for large volumes of product.
- R: Specifies the fin spacing optimized for Medium Temperature This configuration balances high cooling efficiency with the ability to handle the moisture loads typical of fresh produce and dairy storage.
- E1U: Indicates the factory-fitted Electric Defrost This includes high-wattage heaters in the coil and drain pan, which are essential for maintaining peak performance in the UAE’s high-humidity environments, especially when operating near or below $0^{\circ}C$.
In the Middle East, the 3C-E 3454 R + E1U is an industry favorite for large supermarket cold stores, catering logistics hubs, and food processing plants. Its four-fan setup creates a powerful, uniform air curtain that maintains temperature stability even in very wide rooms.
Key Features
- Massive Quad-Fan Airflow: Four 300mm fans provide an ultra-wide air distribution pattern, ensuring no “dead zones” in large rectangular storage areas.
- Maximum Heat Exchange: The deep 54-class coil provides a significant increase in cooling kilowatts compared to standard units, ideal for high-turnover storage.
- Integrated Electric Defrost (E1U): High-grade stainless steel heaters ensure rapid defrosting, preventing ice buildup and ensuring continuous airflow in humid conditions.
- Robust Coastal Build: The galvanized steel casing features a white polyester powder coating, providing excellent protection against the corrosive salt air of coastal cities like Dubai and Abu Dhabi.
- Accessible Maintenance: Includes large, removable side panels and a hinged drain pan, allowing for fast and hygienic cleaning by technical teams.

Frequently Asked Questions
- Q: Why choose the 3454 over a single large fan unit?
- A: The 4-fan configuration provides a much wider distribution of air, which is superior for rooms that are very wide, ensuring every pallet or shelf receives direct airflow.
- Q: Is the E1U system necessary for chilled storage?
- A: In the UAE, yes. High humidity often causes frost even at chilled temperatures ($+2^{\circ}C$). The E1U system ensures the unit stays efficient without manual intervention.
- Q: Can it be used for long-term frozen storage?
- A: While it has electric defrost, the “R” fin spacing is best for medium temperatures. For deep-freezing ($-18^{\circ}C$ and below), we recommend the “L” series with wider fin spacing to handle heavier ice loads.
