Air Cooled Evaporator – TS

Coil Specifications:

• Advanced coil with ⅝-inch tubes for superior heat transfer efficiency.
• Fin spacing options: 6mm, 7mm, 10mm, and 12mm, designed for different applications.
• Nitrogen charging up to 5 bar pressure.
• Coil testing and degreasing after manufacturing.

Device Capacity:

• The TS evaporator is customizable for various capacities.
• Suitable for freezing tunnels and cold storage applications.

Body Specifications:

• Unique body coating made of galvanized sheet with electrostatic paint finish.
• Special body design for enhanced durability and aesthetics.
• Internal aluminum drain pan to improve heat transfer efficiency and ensure complete defrosting without ice falling into the drain hole.
• Special external drain pan structure for efficient water drainage during defrosting.

Electrical and Fan Specifications:

• 50cm 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 (Italy), 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.
• Heating element retaining clips.
• 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).
• Compatible with refrigerants: R-717, R-404a, R-1134a, R-22.

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 freezing tunnels and cold storage applications.
• Advanced coil design with ⅝-inch tubes.
• Fin spacing options: 6mm, 7mm, 10mm, and 12mm for different applications.
• Nitrogen charging up to 5 bar pressure.
• Coil testing and degreasing after manufacturing.

How an Evaporator Works:

An evaporator is a type of heat exchanger where a liquid refrigerant enters a set of tubes (coil) and, due to low pressure, absorbs heat from the surrounding fluid (which can be a gas like air or a liquid like water). This causes the refrigerant to reach its boiling point, evaporate, and change phase from liquid to gas. The performance of the evaporator depends on factors such as the type of fluids, surface area, tube material, temperature difference, etc.
