Air Cooled Evaporator – TF2

Coil Specifications:

• Advanced coil with ½-inch and ⅝-inch tubes for superior heat transfer efficiency.
• Fin spacing options: 5.5mm, 8mm, 10mm, and 12mm, designed for different applications (below zero and freezing tunnels).
• Nitrogen charging up to 5 bar pressure.
• Coil testing and degreasing after manufacturing.

Device Capacity:

• The TF2 evaporator is available with a nominal capacity range of 50 to 150 kW.
• Suitable for freezing tunnels and below-zero cold storage rooms.

Body Specifications:

• Unique body coating made of galvanized sheet with electrostatic paint finish.
• Special body design for enhanced durability and aesthetics.
• Hinged doors with locks on both sides for easy access to terminals and expansion valves during maintenance.
• Internal aluminum drain pan to improve heat transfer efficiency and ensure complete defrosting without ice falling into the drain hole.

Electrical and Fan Specifications:

• 63cm fans manufactured by Ziehl-Abegg (Germany), equipped with motor protection (overload) for fan safety.
• Operating temperature range: -40°C to +60°C.

Heating Element Specifications:

• Defrost and drain heating elements manufactured by the reputable Sedes factory, featuring silicone-coated wires resistant to high temperatures.
• Series wiring of heating elements to reduce voltage difference across the elements to 190V, extending their lifespan.
• High-quality, fully insulated wire terminals to protect against moisture.
• Fan blade heating elements to prevent icing on fan blades (always active).
• Drain funnel and tube heating elements to prevent ice formation in the drain path (always active).

Additional Features:

• Defrost thermostat with adjustable positioning on the coil for optimal defrosting.
• Pre-wired electrical box with oversized terminals (includes fans with overload protection, defrost and drain heating elements, and defrost thermostat).

Installation Guidelines:

• The evaporator should be installed in a suitable location within the cold room, maintaining standard clearance from surrounding walls.
• Avoid blocking airflow in the fan’s air discharge path to ensure proper air circulation.
• Installing a linear heat exchanger improves system efficiency and longevity.
• Side doors must be closed after servicing.

Standard Components:

• U-trap with mounting brackets and installation diagram (for models with 5 to 33 kW capacity).
• Drain funnel (vertical and flat) suitable for the evaporator’s capacity.
• Flexible PVC drain tube with a steel spring, approximately 2 meters long, for efficient water drainage.

Key Features and Advantages:

• Customizable production for various capacities.
• Suitable for below-zero cold storage rooms and freezing tunnels.
• Advanced coil design with ½-inch and ⅝-inch tubes.
• Fin spacing options: 5.5mm, 8mm, 10mm, and 12mm for different applications.
• Nitrogen charging up to 5 bar pressure.
• Coil testing and degreasing after manufacturing.
