Product series:

Cascade low temperature chiller unit (water outlet temperature – 35 ℃-120 ℃. Refrigerating capacity is 5 kw-1100 kw).

At the same time, we can design and manufacture all kinds of non-standard refrigerating units.

-Each set of refrigeration units is based on the user’s specific requirements of refrigerating capacity and performance to ensure performance and reliability.

-Select imported well-known brands of compressors, such as Bizer, Wheel, Siemens, Danfoss

-Single or double stage compressor is used

- 单 - 级，双 - 阶段或级联级制冷系统

-Adopt the internal pressure difference oil supply lubrication system without pump, which is energy saving, efficient and reliable.

- 选择控制部件，如热力学膨胀阀，电磁阀和国际知名品牌的单向阀，以确保广泛的工作条件，在单元的有效和可靠的操作

-A液体致冷剂注入系统在低温下提供有效地降低的关键部件的工作负荷和废气温度，提高了压缩机的工作可靠性

-It has functions of hot gas bypass, energy regulation and complete automatic protection (over voltage, over temperature, overload, inversion, etc.)

-Large systems use open screw compressor with few moving parts and long service life of bearing: medium and small systems use single-stage semi-closed piston compressor or two-stage screw compressor

-The压缩机开始与最小负载下星三角电压下降，可有效地减少了对电网的起动电流和冲击

-The产品将提供全面的测试和满负荷运行试验后，制冷剂制造，设备可以水电之后启动到位

级联式冷水机组高效率 -

-Some heat exchangers are made of stainless steel plate to provide maximum heat transfer area in compact space

-The螺杆压缩机被采用，而经济设备被设置成让系统更高效 - 安排突出机油滤清器。压缩机和高效换热器的正常工作得到有效的保证。

-The special arrangement of heat exchange pipe of evaporator and liquid feed by separate circuit ensures good oil return

Automatic control of cascade chiller unit–

-A新的控制逻辑的系统开发。验证的西门子自动控制系统用于警告系统的关键参数

酮按钮启动并自动停止，并自动增加或减少负载

-It adopts high-precision large-screen touch screen, industrial-grade intelligent controller and advanced computer control system, connects with external equipment. Remote user and control room can realize the following control functions through standard interface:

（1）多重保护：压缩机排气过热，电机过热，冷水防冻等温度保护：过电流，缺相，逆相这些电保护：高压和低压，油位，破水等特殊状态的保护的制冷剂系统。
