Explore our premium product portfolio designed for high efficiency, continuous industrial application and integrated air control.
Shanghai Honest Compressor Co., Ltd. is a British-owned enterprise. It was founded in early 2004. The production address is located at NO. 355 Jiajian Branch Road, Malu Town, Jiading District, Shanghai, China. It is a large-scale manufacturing enterprise specializing in the production of twin-screw air compressors in China. At the same time, it is also an important supplier of air system solutions.
We provide various types of piston air compressors (low pressure, medium pressure, high pressure, oil-free air compressors), screw air compressor systems (3KW-480KW various screw air compressors, gas separation equipment, refrigerant compressors, cold dryers [industrial air dryers], filters, ceramic membrane filtration systems) and various equipment accessories and consumables.
We fully implement strict management throughout the entire manufacturing process, strictly monitor product quality and environmental protection, and are certified under the ISO 9001:2015 quality standard.
How modern moisture separation technologies ensure pneumatic system longevity and maintain pristine air quality under extreme operations.
Integrating microchannel heat exchangers and variable speed scroll compressors, our refrigerated air dryers drop compressed air temperature down to a precise +3°C (+37°F) dew point. The continuous condensate removal prevents piping oxidation, preventing instrument line blockages and securing production uptime.
For critical applications requiring extreme dry air, our twin-tower adsorption desiccant air dryers achieve a Pressure Dew Point (PDP) down to -40°C or -70°C. Utilizing high-affinity activated alumina or molecular sieves, they provide optimal drying through heatless, heated purge, or blower purge technology.
Smart integration with digital hygrometers allows the regeneration cycles of desiccant beds to dynamically scale based on real-time moisture load. This modern control mechanism saves up to 60% of purge air losses, significantly lowering utility expenses for multi-stage facilities.
Aligned with global ecological initiatives, Shanghai Honest Compressor Co., Ltd. has redesigned its refrigeration circuits to operate with eco-friendly refrigerants like R134a and R407C. Combined with high-efficiency scroll and screw configurations, we provide unmatched cooling efficiency with minimal carbon footprint.
In industrial applications, compressed air is more than just a utility; it is a primary power source that must comply with strict international purity levels. Moisture, oil vapors, and airborne particulates represent severe vectors of process contamination. Inadequate treatment leads to corrupted product runs, component wear, and unplanned factory shutdowns.
Working with Shanghai Honest Compressor Co., Ltd. ensures your compressed air infrastructure satisfies the demanding requirements of ISO 8573-1:2010 Air Quality Classifications. By pairing our twin-screw compressors with custom-engineered cold dryers, ceramic membrane filters, and oil-free blower systems, we deliver systemic purification configurations tailormade for distinct industry profiles:
Requires complete sterility and zero oil carryover. We recommend Class 0 oil-free blower configurations combined with desiccant dryers reaching a stable -40°C PDP. This configuration prevents bacterial growth in medical piping systems and guarantees pure process air during chemical synthesis.
Even a trace of moisture can degrade ultra-fine microelectronic circuitry. Our extreme-low dew point adsorption dryers (-70°C PDP) remove all volatile water vapor, protecting multi-billion dollar wafer lithography and precision vacuum equipment from moisture-induced defects.
Water droplets in automotive spray booths cause paint blistering and uneven adhesion. Our integrated screw compressor and cold dryer systems provide continuous moisture extraction. This ensures consistent paint finishes, reliable pneumatic tool performance, and trouble-free control valves.
Operating from our modern production base at NO. 355 Jiajian Branch Road, Malu Town, Jiading District, Shanghai, we leverage China's advanced supply chain environment and combine it with rigorous British engineering standards. This hybrid design allows us to manufacture highly durable products at optimized price points.
By utilizing advanced vertical integration, we fabricate structural cabinets, wind rotors, heat exchangers, and separator vessels in-house. This complete cycle monitoring ensures that every twin-screw compressor or cooling dryer assembly complies with strict ISO standards before dispatch. Our location in Jiading, Shanghai, offers access to robust logistics networks, ensuring fast delivery of raw materials and finished products to ports and international container terminals.
All air compressors and drying equipment undergo thorough dynamic testing. Our energy consumption data consistently outperforms national benchmarks, ensuring substantial energy savings and lower operating costs for your plant.
Our manufacturing footprint and performance benchmarks speak for themselves.
For procurement managers and system engineering firms, buying industrial machinery requires addressing multiple technical and regulatory variables. Factors like varying electrical grids (e.g., 220V/50Hz single phase, 380V/460V 3-phase systems) and country-specific pressure vessel regulations (ASME, PED, CE, UL) demand technical flexibility from equipment suppliers.
Shanghai Honest Compressor Co., Ltd. addresses these challenges by offering a structured OEM/ODM framework. Our engineers handle customized voltage adaptations, explosion-proof requirements, and marine-grade corrosion coatings. We specialize in providing complete, drop-in skid-mounted modules that include compressors, desiccant or refrigerant dryers, filtration blocks, and control panels for fast installation.
To facilitate contact and communication between customers and enterprises, we offer a dedicated service hotline: 400-705-9168. We support this with a network of local dealers and field-service teams across major Chinese and global shipping centers. This ensures that you receive technical support, preventive maintenance, and quick delivery of replacement consumables when you need them.
Expert insights addressing common engineering, operational, and maintenance inquiries.
A: The primary differences lie in the operating principle and the resulting dew point. A refrigerated (cold) air dryer cools the air to about +3°C (+37°F), causing water vapor to condense into liquid, which is then drained. This is sufficient for general manufacturing and shop air. A desiccant air dryer uses chemical desiccant beads (activated alumina or molecular sieves) to adsorb moisture, achieving a Pressure Dew Point (PDP) of -40°C to -70°C. This level of dry air is necessary for packaging, electronics, pharmaceuticals, and sub-freezing outdoor operations.
A: Standard desiccant dryers switch towers on a fixed timer (e.g., every 5 to 10 minutes), even if the desiccant material is not saturated. Dew Point Demand Control monitors the moisture level at the active tower's outlet. It only initiates regeneration once the desiccant bed is fully loaded. This reduces purge air loss, limits heating cycles, and cuts energy use during periods of low flow.
A: Yes. We offer comprehensive OEM customization. This includes C5-M high-durability epoxy coatings for marine settings, stainless steel structural panels, explosion-proof motors (ATEX/IECEx certified), marine classification approvals (LR, DNV, BV, CCS), and tailored electrical configurations (such as 440V/60Hz or 690V setups).
A: Important preventive steps include checking the automated condensate drain valves daily, cleaning the condenser coil weekly to prevent overheating, and replacing pre- and post-filter elements every 3,000 to 4,000 hours of operation. High differential pressure across the dryer points to element fouling, which can reduce downstream pressure and decrease overall air flow.
A: As a British-owned enterprise established in 2004, Shanghai Honest Compressor Co., Ltd. combines European engineering standards and quality control with China's cost-effective supply chain and skilled manufacturing workforce. This combination allows us to deliver high-quality, ISO-certified twin-screw air systems at competitive prices for customers worldwide.
