Product Range
We supply a wide range of commonly used refrigeration system accessories, including needle valves, electronic expansion valves, check valves, motorized ball valves, low pressure transmitters, high pressure transmitters, solenoid valves, filter driers, four-way reversing valves, plate heat exchangers, controllers, and other related components.
Main Accessories
Needle Valve
Used for fine flow adjustment in fluid or refrigerant pipelines, suitable for systems requiring stable and precise control.
Electronic Expansion Valve
Used to accurately control refrigerant flow, improving evaporator efficiency and helping the system operate stably under different load conditions.
Check Valve
Prevents medium backflow and protects system equipment by ensuring refrigerant or fluid flows in the designed direction.
Motorized Ball Valve
Suitable for automatic pipeline control, enabling quick opening, closing, and remote operation for improved system efficiency.
Low Pressure Transmitter / High Pressure Transmitter
Used to monitor system pressure changes and provide reliable data for equipment control, operation protection, and fault diagnosis.
Solenoid Valve
Controls the on/off flow of refrigerant or fluid, widely used in refrigeration systems, heat pump systems, and automatic control pipelines.
Filter Drier
Removes moisture and filters impurities from the system, helping protect compressors, valves, and heat exchangers while improving system reliability.
Four-way Reversing Valve
Mainly used in heat pump and heating/cooling switching systems to change between cooling and heating modes.
Plate Heat Exchanger
Used for auxiliary heat exchange, heat recovery, compact heat transfer systems, or special working conditions.
Controller
Supports system operation control, parameter adjustment, pressure protection, temperature control, and automatic management.
Product Advantages

Applications
These accessories are widely applicable to shell-and-tube evaporators, shell-and-tube condensers, water chillers, heat pump systems, cold storage refrigeration systems, and other refrigeration and heat exchange systems.
Full Series：A full range of designs is available for Hanbell, Bitzer, RefComp, Fusheng and other compressors under air-conditioning, standard, and low-temperature operating conditions.
Application Scenarios：Suitable for air-conditioning refrigeration, industrial chilled water, brine ice making, vegetable pre-cooling, and flower freeze-drying.
Adjustable Structure：Stable L-shaped or triangular structure with reasonable tube layout. Various component supports and unit connection pipes can be customized according to user requirements, reducing unit assembly time by 50%.
Application Scenarios：Suitable for marine refrigeration, seawater cooling, and aquaculture refrigeration systems.
Material Selection：Heat exchange tubes are available in aluminum brass, copper-nickel, titanium, and other materials.
Strong Corrosion Resistance：End covers can be made of aluminum bronze, polymer, anti-corrosion coating, or duplex stainless steel for stable performance in seawater conditions.
Full Series：A full range of designs is available for 3P-50P semi-hermetic compressors such as Bitzer, Copeland, and RefComp.
Material Selection：The heat exchange tubes can be made of high-efficiency copper condenser tubes or stainless steel tubes for lower cost.
Structural Features：Universal compressor base, integrally formed water chamber, and compact structure.
Uniform Distribution：The falling film distributor features a five-stage liquid distribution mechanism, allowing the inlet liquid to be evenly sprayed onto each copper tube.
High-Efficiency Tooth Profile：The tooth profile of the falling film evaporator tube is optimized to improve heat exchange efficiency.
High Oil Separation Efficiency：Equipped with a standard external oil separator and a two-layer labyrinth filter structure, providing higher oil separation efficiency.
Uniform Distribution：The bottom liquid distribution plate is reasonably designed to ensure proper flow velocity after distribution, avoiding liquid climbing along the side wall caused by excessively high flow velocity.
High-Efficiency Tooth Profile：The tooth profile of the flooded evaporator tube is optimized to improve heat exchange efficiency.
High Oil Separation Efficiency：Equipped with a standard external oil separator and a two-layer labyrinth filter structure, providing higher oil separation efficiency.
