EHT Air Evaporator

EHT Air Evaporator Coil Specifications

• Advanced Coil with High-Performance ½-inch Copper Tubes: Designed for superior heat exchange.
• Extended Tube Length: Compared to 5/8-inch tubes, ½-inch tubes offer increased length, enhancing heat transfer efficiency by extending the refrigerant’s pathway within the coil and increasing the number of coil rows (ROW).
• Customizable Fin Spacing: Coils are available with fin spacing of 5mm or 8mm to meet various cooling requirements.

Unit Capacity

• EHT Evaporator Models: Available in 28 models with a nominal capacity range of 5 to 48 kW.
• Applications: Suitable for below-freezing and above-freezing cold storage, as well as pre-cooling facilities.

Body Specifications

• Unique Galvanized Body Coating: Coated with electrostatic paint for durability and an attractive finish.
• Specialized Body Design: Features reinforced structure for improved durability and aesthetics. Includes hinged doors with locks on both sides of the evaporator for easy access to the terminal and expansion valve during maintenance.
• Hinged External Drain Pan: Simplifies periodic servicing and inspection of the heaters.
• Aluminum Internal Drain Pan: Enhances heat transfer efficiency, ensuring complete ice melting and preventing ice from falling into the drain outlet.
• Special External Drain Pan Structure: Effectively channels defrost water, ensuring proper drainage.

Electrical and Technical Specifications

• Axial Fans: Designed to operate within a temperature range of -40°C to +60°C.
• Built-in Overload Protection: Protects the fans from electrical damage.
• Thermal and Protective Classes: Equipped with thermal class F and protection classes IP54 and IP55.
• Fan Sizes: Uses 40 cm and 50 cm fans, tailored to the unit’s capacity.

Heating Element Specifications

• Defrost and Drain Heaters: Manufactured by the reputable Sedes company, with heat-resistant silicone-insulated wiring, pre-wired inside a junction box.
• Series Wiring: Reduces the voltage difference across the heater to 190 volts, extending heater lifespan.
• High-Quality Terminals: Fully insulated and moisture-resistant wire connections.
• Holder Clips: Ensure secure placement of heating elements.
• Anti-Icing Features for 50 cm Fans: Equipped with heaters around the fan blades to prevent ice formation (always active).
• Drain Funnel and Pipe Heater: Prevents freezing of drain water in the outlet path (always active).

Additional Features

• Defrost Thermodisc: Can be installed at various positions on the coil for optimal defrosting.
• Electrical Box: Includes oversized terminals and pre-wired connections for fans (with overload protection), drain and defrost heaters, fan anti-icing heaters, drain funnel heaters, and the defrost thermodisc.
