First, the product features:
1, a wide range of options
Piston type - single stage parallel (20HP ~ 350HP), evaporation temperature of 7.5 ℃ ~ -45 ℃.
Piston - stand-alone two-stage parallel (16HP ~ 180HP), evaporation temperature -25 ℃ ~ -65 ℃.
Screw - single-stage parallel (80HP ~ 600HP), evaporation temperature 5 ℃ ~ -45 ℃.
Screw - stand-alone two-stage parallel (100HP ~ 600HP), evaporation temperature -30 ℃ ~ -65 ℃.
Applicable to a variety of refrigerants R404A, R507A, R407C, R22.
2, stable and reliable operation
The use of international high-quality well-known brands of compressors and parts, follow the international advanced design concepts, the perfect combination of a safe and reliable system.
Each set of units are standard: the lack of phase, reverse phase sequence, over voltage, under voltage, oil pressure, high pressure, low voltage, motor overload, including a full set of security protection modules, and can effectively avoid frequent shutdown control.
Efficient oil separation system, the unit does not need to add after the start of lubricating oil, the standard oil temperature heater (screw machine), oil temperature controller (screw machine), oil level switch (screw machine), so that units worry-free operation The
Each unit is shipped with standard PLC controller, according to the cooling needs of automatic adjustment of the number of compressor operating units, balanced single compressor running time, saving power loss, so that unit life and single unit compared to more than 30% extension.
Unique low environmental condensation pressure constant adjustment system, put an end to the environmental temperature is low or liquid flow alarm phenomenon, to ensure the stable operation of the system.
Efficient gas-liquid separation device and a unique pipe design, to maximize the possibility of compressor compressor to avoid.
Containers with pressure vessel card, standard safety relief valve.
Configure the fault separation device, when a compressor failure other compressors still work properly to ensure the normal use of the customer.
3, energy efficient
Due to the large amount of cooling required during the operation of different seasons in the whole year, the unit should have high capacity control in order to maintain the efficient operation state for the load fluctuation.The average efficiency of the parallel unit is different according to the refrigeration system, High 30%.
Multiple head parallel operation, can provide multi-level energy adjustment series, the cooling output can be more smooth dynamic match the actual use of the load.
The use of highly efficient oil separator, lubricants only a small part of the system, more improve the efficiency of the heat exchanger.
 PLC controller according to the return air pressure to adjust the number of units, the unit part of the load, but also to maintain the highest efficiency
 PLC controller can set the best running curve (grid valley and valley), for the end-user to save a lot of power.
Provide "modular" installation concept, reduce on-site construction risk, shorten the construction period, improve product quality controllability.
Simple and convenient operation
PLC safety automatic control, configuration touch screen Chinese menu, graphical control interface to facilitate the operation, visual display equipment running status, data logging, parameter setting and fault alarm.
Reserved for remote communication interface, to facilitate customer remote monitoring
With print output port, printer unit and system operating history
