Ceiling Type Double-Side Blow Evaporator is a specialized heat exchange unit designed specifically for cold storage environments where space optimization and gentle airflow are critical. Unlike standard evaporators that blow air in a single direction, this dual-discharge configuration draws air from the center and exhausts it through two opposing sides. This design minimizes high-velocity air impact on stored products and provides a more uniform temperature distribution.
As a core product line of Zhejiang Kaidi Refrigeration Equipment Co., Ltd, our Ceiling Type Double-Side Blow Evaporator leverages 30 years of engineering expertise. These units are engineered to meet the stringent demands of food processing workshops, pharmaceutical storage, and logistics centers where personnel often work directly beneath the units.

The fundamental principle of the Ceiling Type Double-Side Blow Evaporator involves high-efficiency heat transfer between the refrigerant flowing inside the copper tubes and the air circulated by the fans.
Air Intake: Warm air is drawn upward into the center of the unit by axial fans.
Heat Exchange: The air passes through a high-density aluminum fin and copper tube heat exchanger.
Symmetrical Discharge: The cooled air is then forced out through both horizontal sides.
Coanda Effect: By mounting the unit close to the ceiling, the discharge air follows the ceiling surface, extending the air throw and preventing "dead zones" in the room corners.
Kaidi’s Engineering Advantage: Our R&D center in Shanghai (Hongqiao) has optimized the fin spacing and tube geometry to ensure that the Ceiling Type Double-Side Blow Evaporator achieves maximum heat exchange efficiency with minimal frost accumulation, a result of our decades of field-testing across global climates.
| Feature | Double-Side Blow Evaporator | Standard (Single-Side) Blow Unit |
| Airflow Velocity | Low to Moderate (Gentle) | High (Concentrated) |
| Temperature Uniformity | Excellent (Symmetrical distribution) | Average (Coldest near the outlet) |
| Space Utilization | Ceiling mounted; saves floor/wall space | Wall mounted; takes up pallet space |
| Occupational Comfort | High (Reduced draft on workers) | Low (Strong cold wind in specific areas) |
| Ideal Application | Processing rooms, low-ceiling warehouses | High-ceiling blast freezers, bulk storage |
The versatility of the Ceiling Type Double-Side Blow Evaporator makes it the preferred choice for specific industrial needs:
Food Processing Workshops: At a large-scale meat processing facility in Guangzhou, Kaidi installed double-side blow units to ensure a stable $+10^{\circ}\text{C}$ environment. The low-velocity airflow prevents surface drying of the meat while ensuring a comfortable working environment for hundreds of staff.
Pharmaceutical Cold Chain: For sensitive vaccine storage, these units provide the $\pm 0.5^{\circ}\text{C}$ temperature stability required by international standards.
Supermarket Cold Rooms: Used in walk-in coolers where space is premium and frequent door openings require rapid but gentle recovery of set temperatures.
To maintain the high performance of Kaidi refrigeration equipment, we recommend the following maintenance schedule:
Monthly Fin Inspection: Check the aluminum fins for dust or debris. Clean with a soft brush or low-pressure air to prevent airflow restriction.
Defrost Verification: Ensure the electric heating elements (if equipped) are functioning correctly to prevent ice buildup on the coil.
Fan Motor Lubrication: While most Kaidi fans utilize maintenance-free bearings, regular checks for vibration or unusual noise can prevent motor failure.
Drainage System: Clear the drain pan and lines of any sludge or ice to prevent water leakage into the cold room.
Q: Why choose a Ceiling Type Double-Side Blow Evaporator over a standard unit?
A: The primary reason is airflow management. If your cold room has a low ceiling or if people are working inside, the double-side blow prevents the "wind chill" effect and ensures the temperature is consistent on both sides of the room.
Q: What materials are used in Kaidi evaporators to prevent corrosion?
A: At Zhejiang Kaidi Refrigeration, we use high-grade hydrophilic aluminum fins and seamless inner-grooved copper tubes. For harsh environments (like seafood storage), we offer specialized anti-corrosion coatings to extend the equipment's lifespan.
Q: Can these units be used for deep freezing?
A: While they are highly effective for chilling and medium-temperature storage, we typically recommend our dedicated high-velocity series for blast freezing. However, customized double-side blow units can be engineered for specific low-temperature holding applications.
Q: How does Kaidi ensure the quality of its refrigeration products?
A: With over 60,000 square meters of modern factory space and a standardized CNC machining process, every unit undergoes rigorous pressure testing and performance validation in our high-standard laboratory before shipment.
