HLT Series Integrated Screw Air Compressor Unit (4-in-1 Permanent Magnet Variable Frequency Air Compression System)

This HLT series integrated screw air compressor unit is an intelligent air compression system that highly integrates the screw compressor main unit, air receiver tank, refrigerated air dryer, and precision filters into a single compact frame. The core working principle is: air enters the screw compressor chamber through the intake filter, mixes with lubricating oil, and is compressed continuously and smoothly by the twin-screw rotors, forming a high-temperature, high-pressure oil-air mixture. This mixture undergoes three-stage separation in the oil-air separator, and the purified compressed air then sequentially enters the air receiver tank for buffering and pressure stabilization, the refrigerated air dryer for cooling and dehumidification (with pressure dew point reaching 2~10℃), and then passes through multi-stage precision filters (filtration accuracy up to 0.01μm, oil content ≤0.01ppm) to remove residual oil mist and dust particles. The entire compression, purification, and storage process is integrated into one compact unit—users simply need to connect the power supply and air piping to start operation immediately.

In terms of manufacturing quality and structural integrity, this HLT integrated air compressor unit adopts a modular integrated design philosophy, consolidating the traditionally separately installed air compressor, air receiver tank, refrigerated air dryer, and filters into a single unit. The core of the unit—the screw compressor main unit—features high-efficiency asymmetrical rotor profile design with SKF heavy-duty bearings, ensuring smooth and reliable operation with overhaul intervals reaching 40,000 to 80,000 hours. The compressor main unit and motor are connected via coaxial direct coupling or high-efficiency permanent magnet synchronous motor drive, delivering high transmission efficiency with no mechanical losses. The integrated piping system is optimally designed, significantly reducing the length and number of pipe connections, effectively lowering the risk of pipeline leakage and system pressure drop. The refrigerated air dryer features an efficient heat recovery design and R134A/R410A environmentally friendly refrigerants, ensuring stable and dry compressed air even under high-temperature conditions. The precision filters adopt a series-connected four-stage filtration structure, with high-density filter paper effectively removing dust and oil mist to ensure end-use air quality. The entire unit is equipped with a PLC or microcomputer intelligent control system, integrating multiple protection functions including discharge pressure, discharge temperature, oil pressure, and motor overload, enabling automatic load/unload, fault alarm, and remote monitoring.

The performance advantages and application value of this HLT integrated screw air compressor unit are exceptionally prominent. First, plug-and-play, time and labor saving – all components are assembled and tested at the factory; users do not need to separately purchase and install air tanks, dryers, filters, and other accessories. Upon delivery, simply connect power and piping to start operation. Second, significant space savings – the integrated structure reduces the footprint by 40%60% compared to traditional split installations, making it particularly suitable for workshops and factories with limited space. Third, integrated optimization and reliable performance – the internal piping is optimally designed with minimal pressure loss and few leak points; the matching between components is precisely calculated to ensure optimal overall system efficiency. Fourth, high-quality output air – after refrigerated drying and four-stage precision filtration, the compressed air achieves a pressure dew point of 2~10℃, oil content ≤0.01ppm, and dust particle size ≤0.01μm, directly meeting high-quality air demands for laser cutting, precision sandblasting, pneumatic control, and other applications. Fifth, intelligent energy-saving operation – optional permanent magnet variable frequency drive technology enables 0~100% infinitely variable air flow control and constant pressure control, delivering significant comprehensive energy savings.

In terms of application scope, this HLT integrated screw air compressor unit is widely used in sandblasting rust removal (providing dry, clean high-pressure airflow to ensure surface treatment quality), laser cutting (providing high-quality oil-free, water-free auxiliary gas), machinery manufacturing (driving pneumatic tools and automation equipment), automotive manufacturing (assembly tools, pneumatic control, painting), aerospace (machine washing, driving assembly tools), food and medical (providing clean compressed air), electronics and power, as well as chemical, textile, pharmaceutical, and other industrial fields requiring high-quality compressed air. This HLT series integrated screw air compressor unit is an efficient, reliable, high-quality one-stop compressed air solution for modern industrial production.
