Explore our premium-engineered compressed air dryers designed for optimal water-removal efficiency and energy performance.
Founded in early 2004, Shanghai Honest Compressor Co., Ltd. is a British-owned enterprise operating a large-scale manufacturing ecosystem in Shanghai, China. Spanning across our production center at NO. 355 Jiajian Branch Road, Malu Town, Jiading District, we specialize in delivering high-efficiency double-screw air compressors alongside a comprehensive suite of gas purification systems.
As a leading supplier of complete air system solutions, our capabilities cover a wide range of compressed air applications. We manufacture high-performance twin-screw air compressors (3kW to 480kW), industrial piston air compressors (covering low, medium, and high-pressure configurations), oil-free air compressors, gas separation equipment, refrigerant compressors, cold/refrigerated dryers, and advanced filtration units, including ceramic membrane filtration systems.
Quality Management System Commitment: Our production line is fully compliant with the ISO 9001:2015 quality management framework. By integrating advanced production oversight, environmental controls, and rigorous component testing, every air dryer and compressor meets international mechanical safety and durability standards.
How the evolution of automated systems and energy standards impacts modern compressed air treatment specifications.
Environmental mandates such as the EU F-Gas regulations and the EPA AIM Act are transforming how refrigerated dryers are manufactured. Global engineering teams are transitioning systems from legacy R22 to low-GWP alternatives, including R134a, R407c, and R410a, to secure carbon reduction compliance.
VSD (Variable Speed Drive) and permanent magnet integrations in screw compressor-dryer cycles reduce power draws under partial load. We engineer our heat exchangers and chilling loops to run on variable demand, minimizing the overall pressure drops in the compressed air lines.
Modern processing lines demand precision. Depending on the industry (such as pharmaceutical packaging or automotive electrostatic painting), maintaining a stable pressure dew point (PDP) between 2°C and 10°C is required to protect pneumatic valves and eliminate system corrosion.
Tailored configurations optimized to meet critical clean air standards across demanding sectors.
For large mining and heavy manufacturing applications, individual components often present integration challenges. Shanghai Honest Compressor design engineers build complete compressed air stations on single structural skids, co-integrating the rotary screw compressor, air receiver tank, pre-filters, refrigerated air dryer, and post-filtration systems.
Our system configurations deliver optimized flow transitions with minimal piping friction loss. Testing at the National Compressor Inspection Center confirms that our packaged solutions meet strict national energy efficiency grades while offering convenient centralized maintenance access.
By consolidating system engineering with a single partner, operators benefit from unified performance warranties, reduced piping complexity, and pre-commissioned control interfaces.
Years of Engineering Experience
Quality Certified Processes
Maximum Unit Power Capacity
Stable Pressure Dew Point Range
Continuous innovation in air treatment and desiccant materials to maximize plant efficiency.
Integration of compact plate-fin aluminum heat exchangers combining the pre-cooler, evaporator, and moisture separator into a single high-efficiency block. This design minimizes internal pressure drops to below 0.02 MPa and prevents condensation bypass.
Development of algorithms linked to air-inlet temperature sensors that adjust the hot gas bypass valve and compressor frequency. This enables real-time regulation, protecting the evaporator against freezing under zero-flow or low-load conditions.
Moving toward standard integration of Eco-Refrigerants alongside smart Modbus/IoT modules. This allows maintenance teams to monitor dew points, pressure drops, and energy usage metrics remotely from plant control rooms.
Operating as an international exporter, Shanghai Honest Compressor Co., Ltd. ensures that its machinery adheres to international standards. Whether shipping to European markets requiring CE conformity, or markets demanding ASME pressure vessel ratings, our product development cycles prioritize safety and environmental regulations.
To provide comprehensive after-sales support, we run a dedicated technical support hotline at 400-705-9168. We work with an extensive network of regional distributors and field service partners in major global markets to facilitate rapid spare parts delivery, commissioning assistance, and warranty service.
