Star independent brand
The main engine of the refrigeration unit adopts the BITZE,BOKE/FS /HANZHONG brand, which is a well-known brand host in China, which is widely used in China, with a low failure rate and stable and reliable operation.
High refrigeration efficiency and fast cooling speed
All refrigeration units adopt an overall optimized design scheme to reduce the refrigeration loss in the pipeline ratio and ensure the refrigeration efficiency after the unit is assembled.
Strong compatibility and energy-saving operation
Multiple warehouses use parallel refrigeration units, each compressor can provide multi-stage energy adjustment, and the cooling output can be more smoothly and dynamically matched to the actual load, with strong compatibility and energy-saving operation.
Low noise shock absorption design
The reasonable design of the pipeline and the installation of shock absorbers reduce the noise caused by the high-pressure gas vibration pipeline and improve the reliability of the compressor operation.
The unit is fully protected
Including reversed-phase sequence, overvoltage, undervoltage, oil pressure, high voltage, low voltage, electronic low liquid level, low oil level, overload, exhaust temperature protection, high and low oil temperature, etc., the protection function is complete, which increases the stability and safety of the unit operation.
High and reliable oil level control
Using a high-efficiency centrifugal oil separation and return system, the oil discharged from the compressor is separated in the high-efficiency oil and stored in the oil storage tank, and the oil level regulator that controls the oil level in each compressor can evenly supply the oil from the oil reservoir to the compressor system as needed.
Complete safety device design
In order to ensure that the local fault does not affect the whole, sectional and sub-regional control shut-off valves are set up in refrigeration pipelines such as oil circuits, gas pipelines, and liquid pipelines to avoid a large amount of freon losses during maintenance.
Advanced intelligent design
PLC controller: The energy output program can be compiled according to the needs of the system to ensure that the output energy of the unit is dynamically matched with the actual system load to the greatest extent, so as to achieve the purpose of high efficiency and energy saving.
PLC controller: real-time monitoring of compressor units, which not only enhances efficiency, but also improves system life.
The unit runs or stops under the control of the PLC controller, and the running time is accumulated at regular intervals to achieve balanced wear and extend the service life of the compressor unit.
Exquisite selection of materials
The main electrical components of the refrigeration unit are Schneid and Chint brands, the control PLC is Siemens brand, and the touch screen of the unit is Weilun brand;
The key components in the unit are all imported components, which ensures the design requirements and high stability, safety and reliability in the operation of the unit. Compared with other refrigeration compressors, the cost of replacing wearing parts and routine maintenance is reduced, and the investment cost of later operation is greatly reduced.
High standard manufacturing process
Strict manufacturing process, all pipes and containers of the unit are strictly derusted, cleaned and purged before assembly to ensure the internal cleanliness of the unit;
After the completion of the whole machine, the pressure holding test and strict sewage discharge of the whole machine shall not be less than 48 hours to ensure that the unit has no leakage and internal cleanliness.
Reliable unit standardization and humanized design
The unit is set with automatic/manual mode, and the operation mode can be switched according to the use needs;
The arrival of the unit is an integral one, with a small footprint and easy to install and use.
Multi-stage energy regulation is provided, and the cooling output dynamically matches the actual load.
Each compressor in the unit is backup to ensure the reliable operation of the system.
The unit uses high-quality semi-hermetic screw compressors, such as GEA, BIZER, Fusheng, etc.
The use of high-efficiency centrifugal + liquefied oil separator minimizes the possibility of oil entering the system.
Two types of oil supply (differential pressure and pump forced) ensure that each compressor receives an adequate supply of lubricating oil under all operating conditions.
The whole system adopts PLC intelligent control, with multiple protection functions such as phase sequence (ohase loss), overload, pressure overshoot safety, oil level, oil flow, oil pressure difference, etc., and the highly integrated design concept greatly saves the area of the machine room.
