Semi-hermetic Low-noise Open-type Commercial Condensing Chiller Unit

Core Advantages: Its open-structure design provides ample physical space for installation and maintenance, significantly reducing subsequent labor costs. By combining a semi-hermetic dedicated compressor with a high-efficiency condenser, it maintains excellent cooling efficiency even under harsh operating conditions, making it an all-around product among commercial condensing units.

Product Features:
Superior Heat Exchange Efficiency: The condenser uses a high-efficiency internally threaded copper tube with aluminum foil design. This design increases the agitation of the inner tube wall and the heat dissipation area, resulting in a qualitative leap in heat exchange efficiency, easily handling extreme high-temperature environments in summer.

Low-Temperature Start-Up Guarantee: Standard crankcase heater effectively prevents lubricating oil dilution during low-temperature shutdown, ensuring smooth compressor start-up in cold weather.

Low-Noise Fluid Dynamics: Equipped with a low-speed axial flow silent motor, combined with a large-blade, wide-angle design, it greatly reduces air friction noise while ensuring sufficient airflow.

Top-Tier Auxiliary Components: Key accessories such as filters, high and low pressure controls, and sight glasses are all from Danfoss; coupled with a large-capacity receiver, it enhances the system's operational redundancy and reliability.

Robust and Corrosion-Resistant Casing: The unit body is constructed with thickened steel plates and electrostatic spraying, providing exceptional corrosion resistance and extending its outdoor service life.

Applications: This unit, with its quiet operation and ease of maintenance, is widely used in commercial buildings, fresh food supermarkets, and various commercial refrigeration systems requiring low-noise operation.

Common Problems and Solutions:
Problem: Severe frost buildup on the compressor return pipe.

Solution: This may be due to poor heat exchange on the evaporator side or excessive opening of the expansion valve. Check if the evaporator is excessively frosted or fine-tune the expansion valve's overheat setting.

Problem: Dull motor noise.

Solution: Check if the large-angle fan blades are deformed or if the bearings are lacking lubrication. Replace or add grease if necessary.

Important Precautions:
Installation Space: Although it is an open design, sufficient air intake space must be provided on the condenser side to prevent hot air backflow.

Mechanical Control Verification: Before operating the mechanical switches, ensure that all pressure settings match the actual operating conditions. Blindly forcing manual start-up is strictly prohibited.
