Product Details
PRODUCT HIGHLIGHTS
- *Superior Heat Exchange Performance: Our cold room evaporator features high-purity copper tubes mechanically expanded into corrugated aluminum fins with optimized spacing. This construction maximizes the heat transfer coefficient, ensuring rapid cooling and stable temperature maintenance across walk-in coolers and freezers.
- *Robust Fan System with Low Noise Operation: Equipped with high-performance axial fans and external rotor motors, the unit delivers strong airflow with reduced vibration and noise levels. Precision-balanced fan blades guarantee efficient air distribution throughout the cold room without hot spots or dead zones.
- *Efficient Electric Defrost Technology: Integrated electric defrost heaters with drip tray and drain pipe heating ensure rapid frost removal during defrost cycles. This prevents ice buildup on the coil surface, maintains consistent cooling performance, and protects the evaporator from damage caused by excessive frost accumulation.
- *Corrosion-Resistant Construction for Harsh Environments: The housing is available in high-quality aluminum or stainless steel with a durable anti-corrosion coating. The fan guards and mounting brackets are treated for long-term service in humid, low-temperature, and even salty environments typical of seafood and meat processing facilities.
- *Flexible Temperature Range and Refrigerant Compatibility: Designed to operate reliably across medium temperature (0°C to +8°C) and low temperature (-18°C to -35°C) applications. Fully compatible with mainstream refrigerants including R22, R404A, R507, and R134a, offering seamless integration with any compressor or condensing unit.
- *Easy Installation and Service Access: The unit supports ceiling-mounted or wall-mounted configuration with pre-drilled mounting brackets and accessible side panels for electrical connections and refrigerant piping. The hinged service door provides quick access to expansion valves and internal components for routine maintenance.
FAQs
What is the difference between a ceiling-mounted and wall-mounted evaporator?
Ceiling-mounted units distribute cold air evenly across the entire room from above, ideal for square or wide cold rooms. Wall-mounted units blow air horizontally and are better suited for narrow, elongated rooms or spaces where ceiling height is limited. Both options are available with our units.
How do I choose between electric defrost and hot gas defrost models?
Electric defrost is simpler to install and control, making it ideal for small to medium cold rooms with moderate frost load. Hot gas defrost uses the compressor's discharge gas to melt ice faster and more energy-efficiently, preferred for large industrial freezers with heavy frost accumulation. The choice depends on your condensing unit configuration and frost frequency.
What materials are the heat exchange coils made of?
Our evaporator coils are constructed with high-purity seamless copper tubes for the refrigerant circuit and corrugated aluminum fins for air-side heat transfer. The tubes are mechanically expanded into the fins for optimal thermal contact. Aluminum fins can be upgraded with hydrophilic or epoxy anti-corrosion coatings for aggressive environments.
How do I determine the correct evaporator size for my cold room?
Please provide your cold room dimensions (L x W x H), storage temperature, product type and incoming temperature, daily throughput, door opening frequency, and ambient conditions. Our engineers will calculate the total heat load and recommend the matching evaporator model with the correct cooling capacity and airflow.
Can the evaporator be used with any refrigerant type?
Our standard evaporators are compatible with R22, R404A, R507, and R134a. The expansion valve orifice and distributor are selected based on your specified refrigerant. If you plan to use alternative refrigerants such as R448A or R449A, please inform us so we can configure the correct expansion device.
How often does the defrost cycle need to run?
This depends on room temperature, humidity levels, and door opening frequency. For low-temperature freezers (-18°C to -25°C), defrost is typically set every 4-6 hours for 15-25 minutes. For medium-temperature chillers (0°C to +8°C), defrost may only be needed once or twice daily. The controller can be programmed to your specific conditions.
What maintenance is required to keep the evaporator running efficiently?
Routine maintenance includes checking and cleaning the coil fins every 1-3 months to prevent dust and debris blockage, inspecting the drain pan for proper drainage, verifying fan motor operation, and checking electrical connections. The defrost heater and thermostat should be tested periodically before peak seasons.
Is the evaporator suitable for use in a seafood or highly corrosive cold room?
Yes, we offer specially treated models for corrosive environments. Options include stainless steel casing, epoxy-coated aluminum fins, and anti-corrosion treatment on fan guards and mounting hardware. These upgrades protect against salt spray, high humidity, and acidic conditions common in seafood and meat processing facilities.
