Company profile
Built on environmental-engineering implementation and equipment-manufacturing expertise, DEWTEK DRYING SYSTEMS CO., LTD. provides environmental-protection equipment design and manufacturing, environmental-engineering planning and implementation, and related technical services. With more than ten years of system-design and equipment-manufacturing experience, the company integrates energy-saving systems across refrigeration and air-conditioning, thermal-energy recovery, and wastewater and environmental engineering. Its energy work helps customers clarify heating and cooling energy use, identify major sources of energy loss and recovery opportunities, and move energy saving from isolated equipment improvement to practical results across the complete process and equipment configuration. DEWTEK DRYING SYSTEMS CO., LTD. provides one-stop integrated services from planning and design through equipment selection and on-site implementation, including installation, piping, wiring, commissioning, and acceptance. The integrated-service model is intended to reduce cross-vendor communication and shorten both decision-making and construction timelines, while each project is adapted to actual site conditions and supported by in-house maintenance technicians over the full equipment life cycle. The system-integration approach is intended to make long-term energy-saving performance visible and sustainable across the complete process and equipment configuration.
Exhibits
Dewtek heat-pump drying equipment repeatedly cycles refrigerant through an evaporator, compressor, and expansion valve, absorbing heat from air, compressing the refrigerant to release heat, and reducing temperature again through expansion for continuous drying operation. Because the process is described as a closed heat-pump cycle without an exhaust requirement, the installation does not require end-of-line waste-gas scrubbers or dust collectors for the drying operation and can use less electricity than the compared energy alternatives. For sludge treatment, dewatered sludge can still contain 70%~85% moisture, creating transport cost, leakage, and odor issues, while adding a drying step can further reduce sludge volume by about 40~60% and lower annual hauling expense. The modular heat-pump dryers are described as requiring as little as 0.32 ping of space, with a compact structure, sealed drying circulation, reduced steelwork and ducting, and separately planned main units and lower boxes according to the user's required treatment capacity. Standardized modules are developed for different user requirements, from small to large sludge quantities, and can be flexibly applied across industries to reduce on-site installation time and cost; modules can also be connected according to treatment capacity and expected operating conditions. For corrosion resistance, equipment structures, fins, and heat-transfer tubes are tested and adjusted with physical and chemical dual-coating protection, while nickel and titanium materials are also available as options. The control systems are self-developed and designed for integrated adjustment and equipment-status inspection, with Industrial 4.0 options for real-time data monitoring and multiple safety-protection mechanisms. Compressors are sourced from a major United States manufacturer, while some components and mechanisms are sourced from local manufacturers to support faster maintenance and repair response. Components requiring regular maintenance or inspection can be designed into accessible locations according to operating conditions and service needs, supporting practical inspection and maintenance during equipment use. The drying systems are not limited to sludge; the listed materials and items that can be dried include powders, bulk bags, food waste, industrial components, textiles, glue residue, and paint sludge. The wider equipment and service scope also lists chemical and wastewater treatment, heat-pump energy-saving dryers, liquid concentration, extraction and crystallization equipment, sludge dewatering machines, automatic chemical-dosing preparation machines, air-float turbo blowers, steam boosters, heat-pump water heaters, chillers and refrigeration machines, high-temperature heat pumps, and dual-power food dryers. Related services include environmental-protection engineering, energy-configuration integration engineering, maintenance service, drying-test service, and engineering and control-system integration, connecting the heat-pump dryer with broader energy, environmental, and wastewater projects. Dewtek identifies reduced sludge volume, lower hauling cost, an improved plant environment, and a more positive corporate image among the benefits associated with adding a drying stage after dewatering. The compact closed-circulation drying design also reduces the need for additional environmental-protection equipment that would otherwise add to the installation footprint.
