The EH Series Commercial High Efficiency Ceiling Type Evaporator is designed for commercial refrigeration applications that require efficient cooling, reliable temperature control, and space-saving installation. Its ceiling-mounted structure makes effective use of the available space inside cold rooms, refrigerated warehouses, and other temperature-controlled environments.
As a high-efficiency refrigeration evaporator, the EH Series provides effective heat transfer between the surrounding air and the refrigerant. It is suitable for applications such as cold storage, food preservation, supermarkets, restaurants, food processing, and commercial refrigeration facilities.
Key Features of the EH High Efficiency Ceiling Evaporator
High-Efficiency Refrigeration Evaporator
The EH Series is designed to provide efficient heat exchange and stable cooling performance. The optimized evaporator structure helps improve heat transfer and supports consistent temperature conditions inside the refrigerated space.
Commercial Ceiling Type Air Cooler
The ceiling-mounted design allows the evaporator to be installed above the storage area, helping save valuable floor space. This makes the EH Series suitable for commercial cold rooms and refrigeration facilities where efficient space utilization is important.
Optimized Heat Transfer Coil
The evaporator coil provides an effective heat exchange surface for transferring heat from the refrigerated space to the refrigerant. The optimized coil structure supports efficient refrigeration performance during continuous operation.
Efficient Fan Air Circulation
The fan system circulates cooled air throughout the refrigerated room. Proper air distribution helps reduce temperature differences and supports uniform cooling across the storage area.
Compact Ceiling-Mounted Design
The compact design allows the evaporator to be installed on the ceiling of a cold room or refrigerated enclosure. This configuration keeps the floor area available for storage and operational activities.
Easy Installation and Maintenance
The EH Series is designed for convenient installation and routine maintenance. The accessible component configuration helps simplify inspection, cleaning, and servicing.
EH Series Commercial Evaporator Technical Specifications

EH Series High Efficiency Evaporator Configuration
The evaporator configuration can include the heat exchange coil, fan system, motor, drain system, mounting structure, and other refrigeration components required for stable operation.
EH Series Refrigeration Cooling Capacity
The required evaporator capacity depends on the cold room size, target temperature, product load, ambient conditions, door-opening frequency, insulation performance, and refrigeration system configuration.
Commercial Refrigeration Evaporator Operating Range
The EH Series can be used for different commercial refrigeration temperature conditions depending on the specific evaporator configuration and refrigeration system requirements.
Medium Temperature Cold Room Applications
For medium-temperature applications, the EH Series can provide reliable cooling for refrigerated storage, fresh food, beverages, dairy products, vegetables, and other temperature-sensitive products.
Low Temperature Refrigeration Applications
For lower-temperature refrigeration applications, the evaporator can be selected according to the required room temperature, refrigeration capacity, refrigerant conditions, and defrost requirements.
Evaporator Coil, Fan & Refrigeration Component Configuration
Refrigeration Evaporator Coil
The evaporator coil is the primary heat exchange component. Refrigerant absorbs heat from the surrounding air as it flows through the evaporator circuit, producing the cooling effect required by the refrigeration system.
Aluminum Heat Transfer Fins
The fins increase the effective heat transfer area of the evaporator and improve heat exchange between the refrigerated air and the evaporator coil.
Evaporator Fan and Fan Motor
The fan system circulates air through the evaporator coil and distributes cooled air throughout the refrigerated room. Proper airflow helps improve cooling uniformity and refrigeration efficiency.
Drain Pan and Drain System
During cooling and defrosting, condensed water may collect around the evaporator. The drain pan and drainage system help remove water from the evaporator and maintain a clean operating environment.
EH Series Ceiling Type Evaporator Models & Selection Guide
Selecting the appropriate ceiling type evaporator requires consideration of the refrigerated room size, target temperature, refrigeration load, refrigerant type, airflow requirements, and installation conditions.
The evaporator should be properly matched with the refrigeration condensing unit and other system components to achieve stable and efficient refrigeration performance.
Ceiling Type Evaporator Dimensions & Installation Requirements
The EH Series should be installed in a suitable ceiling position with sufficient clearance around the evaporator for air circulation, maintenance, and servicing.
Proper installation is important for achieving effective air distribution. The evaporator should be positioned to allow cooled air to circulate throughout the refrigerated space while avoiding unnecessary airflow obstruction.
EH Commercial Evaporator Applications for Cold Storage & Refrigeration
Commercial Cold Rooms
The EH Series is suitable for commercial cold rooms requiring reliable temperature control and efficient ceiling-mounted refrigeration.
Refrigerated Warehouses
The high-efficiency evaporator can be used in refrigerated warehouses for storing food, beverages, agricultural products, and other temperature-sensitive goods.
Food Processing Refrigeration
Food processing facilities can use ceiling-mounted evaporators to maintain appropriate refrigeration conditions during food processing and storage.
Supermarket Refrigeration
The EH Series can support refrigeration requirements in supermarkets and commercial food storage areas where efficient cooling and space utilization are important.
Restaurant & Catering Refrigeration
Restaurants, catering facilities, and commercial kitchens can use the evaporator for refrigerated storage rooms and food preservation applications.
Commercial Refrigeration Systems
The EH Series can be integrated into different commercial refrigeration systems according to cooling capacity, room temperature, and refrigeration system requirements.
Ceiling Type Evaporator vs Floor-Mounted Evaporator
A ceiling type evaporator is installed above the refrigerated area, allowing the floor space to remain available for storage and daily operations. This configuration can be particularly useful for commercial cold rooms where floor space is limited.
The choice between ceiling-mounted and other evaporator configurations should be based on room dimensions, cooling requirements, airflow distribution, maintenance access, and installation conditions.
How to Select the Right Commercial Evaporator for Your Refrigeration System
When selecting an EH Series Commercial High Efficiency Ceiling Type Evaporator, consider the following factors:
Cold room dimensions
Required refrigeration capacity
Target room temperature
Refrigerant type
Product storage requirements
Airflow requirements
Evaporator temperature
Defrost requirements
Installation space
Condensing unit configuration
Correct evaporator selection helps maintain stable room temperatures and supports the overall efficiency of the refrigeration system.
