-The main engine of the refrigeration unit adopts the host of international well-known brand brand, which has been widely used in China, with low failure rate and stable and reliable operation.
Copeland Scroll ZB Series compressors are designed for medium and high temperature refrigeration applications and offer an excellent year-round seasonal energy efficiency ratio. Compared with the traditional reciprocating piston compressor, the Copeland scroll compressor has few moving parts, and the unique flexible scroll design makes it have excellent liquid shock resistance and high reliability. At the same time, Copeland scroll compressors are lightweight, compact in design, and low in noise and vibration.
Emerson's /ZFI/ZSI series of cryogenic scroll compressors are tailored for refrigeration applications and feature a Copeland flexible scroll design that combines light weight, compact design, low noise and vibration, excellent reliability, and excellent resistance to liquid shock. There are two series of liquid spray and jet enthalpy increase, /ZSI series uses liquid spray technology to control the exhaust temperature and extend the operating range of the compressor; The ZFI series adopts jet enthalpy technology and subcooler, which can improve the cooling capacity and energy efficiency ratio by 40% and 20% at low temperatures. Other important features include low condensing temperature operation, a wide operating range and fast winding speeds.
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.
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.
Exquisite selection of materials
The main electrical components of the refrigeration unit are Sch 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.
