Product Description

Compactor
1. Selecting brand-new compressor units,

2. Adhering to standardized design criteria,

3. Configuring according to process requirements, refraining from arbitrary alternative solutions, Strictly controlling product quality,

4. Prohibiting the use of repaired or
second-hand refurbished machines.

 

Some manufacturers may reduce the configuration or even use refurbished compressors.

Heat Exchanger

1. Screw-type evaporators equipped with heat exchange tubes of 0.7mm/0.8mm/1.0mm wall thickness,

2. Water-cooled condensers fitted with heat exchangers of 1.1mm/1.2mm wall thickness,

3. Choice of tube materials including purple copper, aluminium brass, stainless steel, or titanium, according to requirements.

 

Many other manufacturers often use condenser heat exchange tubes with wall thickness below 1.1mm, and evaporator heat exchange tubes are frequently 0.6mm, 0.5mm, or 0.35mm.

 

Expansion Valve
1. Primary configuration of high-precision electronic expansion valve,

2. Achieving accurate liquid supply and adjustable settings,
3. Meeting diverse operational requirements under varying unit conditions,

4. Enhancing energy efficiency while preventing compressor overload,

5. Adaptive control for efficient adjustment, yielding noticeable energy savings,

6. Electronic expansion valve enables
automatic regulation from 10% to 100%.

 

The majority of manufacturers use thermal expansion valves or capillary tube throttling.

 

Control System
1. Siemens PLC paired with a 7-inch high-definition touchscreen control panel,
2. Comprehensive unit fault alarm and protection functions,
3. Full-range status display and operational
logging capabilities,
4. User-friendly control system with logical and clear interface, Innovative intelligent temperature control, automatic start-stop, and overload protection functions.
