Share
Feature
Products Features
1. Twin screw compressor brand is employed, with high efficiency, low noise level, less wearing and long operation time.
2.Four stage volume control or 0%-100% automatic regulation.
3.Use PLC microcomputer control from Germany SIEMENS. LCD touch screen, both English and Chinese human-machina intertace.
4.Perfect breakdown protection: high and low pressure protection, air discharge protection, oil level protection, water flow protection, reverse and lack phase protection, chilled water anti-freezing protection, cooling water overheat protection.
Product options
1.Salt water evaporator
2.Stepless energy regulation
3.Whole heat recovery/partial heat recovery
4.Pump control
5.Special power supply
6.Remote communication connector
Product specfication
Refrigerant: R22/R407C
Evaporator max water pressure drop: 1.0Mpa
Evaporator: fouling factor 0.018m2.℃/KW
Power supply: 380V/3P/50Hz
Allowable voltage fluctuate: ±5%
Allowable frequency fluctuate: ±2%
The unit uses high efficiency heat exchanger with advanced, unique shape design and systems. Units can be installed directly on the roof, or other well-ventilated place outdoors, without a separate room, space saving construction. Compact shape, appearance, unit uses “W” type coil design, space utilization, small unit size, in order to adapt to the outdoor weather conditions to ensure that the unit has a good operating results during the life cycle.
Friendy choose to use environmentally R407C, R134A or R410A refrigerant ect.
There may be change of the dimensions without pre notice. For accurate you are welcome to ask us for installing drawing.
