20tons 30 Tons 40tons Refrigerated Sea Water Cooling Rsw System Chiller

 

 

Refrigerated Sea Water (RSW) system chiller is a specialized piece of equipment used primarily in the fishing industry to maintain the freshness and quality of the catch. The system cools sea water to a desired temperature, which is then circulated around the fish hold tanks to preserve the catch fish. 

Components of an RSW Cooling System Chiller
Chiller Unit: The main component that cools the seawater. It typically consists of a compressor, evaporator, condenser, and an expansion valve.

Seawater Pumps: These pumps draw seawater from the ocean and circulate it through the system.

Heat Exchanger: This is where the seawater is cooled by the refrigerant.

Holding Tanks: Tanks where the chilled seawater is stored before being circulated through the fish hold.

Control System: Includes sensors, thermostats, and control panels to monitor and regulate the temperature and flow of the seawater.
 

Flexible Design, Customizable Configurations available in various sizes and configurations to fit different types of vessels and specific requirements.

Robust Construction, Marine-Grade Materials built with corrosion-resistant materials such as stainless steel and marine-grade aluminum to withstand harsh marine environments. Durable Components with High-quality pumps, compressors, and heat exchangers designed for long-term operation and reliability.

Safety and Monitoring, Equipped with alarms to notify operators of any issues such as temperature deviations or system malfunctions,advanced systems offer remote monitoring capabilities, allowing operators to check system status and performance from a distance.
 

Main Components system:

Compressor, The heart of the refrigeration cycle, compressing the refrigerant and enabling heat exchange.Adopt reliable and durable comoressor brand Emerson Copeland, Danfos, Bizte, Hanbell and Jingwei, they are different types by scroll, piston, and screw.Evaporator: The component where the refrigerant absorbs heat from the seawater, cooling it down, connect with water tanks, water must be sanitary, material to use PPR or stainless steel 316L shell and internal with Titanium tube.

Condenser: Dissipates the heat extracted from the seawater, usually pump from and discharge to ocean sea water, cooling tower does not need, ususally material made of stainless steel 316 shell and copper nickle tube,  before condenser and evaporator, filter strainer is required to filter the dirty substance.

Expansion Valve: Regulates the flow of refrigerant into the evaporator, reducing its pressure and temperature. Seawater Pumps: Circulate seawater through the system for continuous cooling.
Control system, advanced Control Systems: Automatic Temperature Control with sensors and thermostats to automatically regulate and maintain the desired temperature, Easy-to-use control panels for monitoring and adjusting system settings.

Electric cabinet, adopt Schneidr electric components, cabinet can be placed on the chiller unit or separate for remote installation, material made of stainelss steel 316 or plastic.
Refrigerated Sea Water (RSW) system is designed to provide efficient cooling and preservation of seafood on fishing vessels, many standard and optional device for different compressor and capacities, such as vibration absorber, solenoid valve, oil separator, soft starters, shut off valves,etc. we will provide the most efficiency and reliable system for each client.

 
Protection device applied to this system:High/Low Pressure protection , Phase-sequencing Protection, Overload Protection, Overheat Protection, Water flow protection , Anti-frozen protection, Exhaust overheat protection, Compressor oil level protection.
