OnlyKem Brand Commercial Refrigeration Condensing Unit for Fish

OnlyKem Brand Commercial Refrigeration Condensing Unit for Fish


Commercial refrigeration condensing unit is the key component of cold room or blast freezer room which is commonly used for fish or fruit cold storage. The split units have limitations in terms of cooling capacity and redundancy functions, so that they can not meet the increasingly stringent requirements of the market. Commercial refrigeration condensing unit is a refrigeration unit composed of two or more compressors, which shares a set of parallel refrigeration circuit. The commercial refrigeration condensing unit is usually used in large cold storage projects, energy-saving and redundant.

At present, our commercial refrigeration condensing unit is more used for fish storage and quick freezing. Firstly, the treated fish is put into the blast freezer within 2 to 6 hours for quick freeze, then stored in the freezer room for a long term storage. Usually we use Bitzer, Turin, Frascold etc compressors (according to customer preferences), they are the famous brand in the world.








Advantage of Commercial Refrigeration Condensing Unit
Energy Saving
For example, one fish freezer room for cold storage below -18 degrees and the capacity is 1200 m3 or 2400 m3, it can be designed to change the size of multiple compressors to match the actual load more smoothly and dynamically, then to realize the optimal energy regulation of load change, improve efficiency and save energy.
Accurate pipeline design can minimize pipeline pressure loss and maximize unit efficiency.
Equipped with a high-efficiency main oil separator, it can almost completely separate the lubricating oil from the compressor exhaust port, effectively improving the heat exchanger efficiency.
Provide multi-suction branch control, according to the need, one unit can be used for multiple evaporation temperatures, effectively use the cooling temperature of each evaporation temperature, so that the system runs in the most energy-saving conditions.

Sufficient Safety Valve
The hand valve is installed at both ends of the filter. When the filter element is replaced, only the hand valve needs to be closed, no need to discharge the Freon, and the cost is saved.
Safety valves are installed at both ends of the compressor. When the compressor is maintained, only the hand valve needs to be closed, no need to discharge the Freon, and the cost is saved.
The Freon reservoir is equipped with a pressure relief valve that automatically opens the pressure relief when the system pressure exceeds the set value.
The oil reservoir is provided with a pressure relief valve, and when the system pressure exceeds the set value, the pressure relief is automatically opened to avoid the danger.

Remote Control
Password level control, the client machine can be monitored remotely to know the real-time system running status.
When the customer’s machine is in poor working condition, it can promptly remind and assist the customer to adjust the parameters to ensure that the machine is running well.
The machine can be alarmed if it fails.
Strong database information can help engineers to maintain equipment.
Good machine operating parameters and data support will help OnlyKem’s technicians to assist in machine commissioning and maintenance.
It is not necessary to go to the site to carry out machine maintenance, system parameter setting, fast and fast, and reduce the impact on production.
Patent PLC System
Automatic control of the entire cold storage system. Automatically balance the running time of each machine head, so that the unit life is extended by more than 30% compared with the single unit. Full automation, this is not only control the rack unit, but also the whole cold storage(rack unit, condenser, evaporator).
The liquid Freon can be changed into a gaseous state by heat exchange in the gas-liquid separator, and the compressor is prevented from entering the compressor and causing the liquid hammer to damage the compressor.
The liquid tank is filled with a liquid level sensor alarm, remind Freon when the liquid level of the accumulator drops to a dangerous level.
Disaster Tolerance Function

When one of the compressors in the unit fails, the other compressors can continue to work normally without affecting the storage safety of all the goods, and can be repaired separately.




OnlyKem commercial refrigeration condensing unit is an optimized combination with high efficiency, reliability, convenient installation and good performance. It is suitable for cold rooms, farms, hotels, restaurants, hospitals, etc.. Welcome to any inquiries about refrigerators or commercial refrigeration and condensation units, your support is our driving force forward.

Freezer room

Freezer room (also called blast freezer, shock freezer) is a kind of cold room with lower storage temperature from -40°C to -10°C, it is equipped with more thicker doors, PU panels and more powerful condensing units than cool room. Freezer room addresses cold storage concerns of storing material reliably at consistently low temperature and fast cooling speed, so it can keep such stored products like sea food, meat or ice scream in fresh quality. The microorganism that affects the quality of food will be refrained or killed in the extremely cold environment inside freezer rooms with temperature less than -18°C. The blast freezer can be quick freezing of stored products from +70°C to -18°C in less than 4 hours to keep the food in fresh conditions. Freezer rooms are widely used in food industry like restaurants, catering unit, bakeries and ice-cream parlors, etc. Our innovative, high quality freezer rooms have the significant advantages of versatility, adaptability, energy efficiency, easy to use. Onlykem is the turn key freezer room solution supplier, all our blast freezers can be customized to satisfy your cold storage requirements with any sizes.
