50% Energy Saving with Dual Effect

Lint Remover Specially for Textile Industry

For Central Air Conditioning Systems

Automatic Lint Removal

Developed for lint-laden textile workshops. It automatically removes lint to prevent heavy clogging of the air conditioner return air, purify the air and improve environmental quality.

50% Power Saving

With the same cooling capacity, power consumption can be reduced by 15,000 kWh per month (24h × 30 days × 23kWh).

Wet Curtain Dust Protection

Air passes through two external filter layers before reaching the wet curtain. It filters airborne dust and achieves high-efficiency cooling.

Workers Comfort and Productivity

Providing a comfortable working environment enhances the well-being of employees.

Comfortable conditions contribute to higher morale, reduced stress, and increased productivity. Employees are likely to perform better in a climate-controlled space.

Improve Product Quality

In certain industries, maintaining a controlled environment is essential for the quality of the products being manufactured where temperature and humidity control are critical for product quality.

High Temperature Problem

Many industrial processes involve the use of machinery and equipment that generate heat. Donco AC helps dissipate this heat, preventing overheating of machinery and ensuring optimal performance and longevity.

Humidity Regulation

Donco AC systems come with dehumidification capabilities, which can be vital in industrial settings. Controlling humidity levels helps prevent issues such as corrosion, mold growth, and damage to sensitive equipment.

Flexible Sox Fibre Air Duct

Flexible Sox Fibre Air Duct is made of flame-retardant fabric material, with a lower initial cost, approximately only 50% of the investment compared to insulated metal air ducts. Additionally, this type of air duct does not generate condensation, and it can be easily disassembled for cleaning during annual holidays. Furthermore, when replacing or upgrading the workshop, all air ducts can be effortlessly removed, providing greater flexibility.

Overall Cooling

Overall cooling in a factory is achieved by implementing Sox Fibre Air Duct evenly throughout the space to deliver cool air, ensuring a uniform temperature distribution.

Spot Cooling

Spot cooling is employed when it is impractical or unnecessary to cool an entire space.

Instead, specific areas are targeted for cooling, allowing for more localized temperature control allowing for energy-efficient and targeted cooling solutions.

 About Donco

Company Overview

As an innovative enterprise focused on sustainable temperature control solutions for industrial environments, Guangdong Dongke New Energy Co., Ltd. delivers full-chain customized energy-saving central air conditioning systems for large-scale industrial scenarios worldwide. Integrating R&D, precision manufacturing, scenario-based planning and full-cycle installation & maintenance, we leverage breakthrough evaporative cooling technology to redefine energy efficiency and operational stability of industrial refrigeration, supporting global manufacturers in low-carbon transition and productivity improvement.

Core Technology & Product Portfolio

Our self-developed water evaporative cooling technology breaks the high-energy-consumption limit of conventional compression refrigeration. It achieves efficient cooling via phase-change heat absorption of natural water, cutting total energy consumption by over 40% versus standard industrial air conditioners and lowering long-term operation costs. Innovatively integrated multi-stage air purification modules resolve common industry pain points: frequent filter clogging, high maintenance cost and heat exchange efficiency degradation under harsh industrial conditions.

We have built six product series for diverse industrial air handling requirements:

Dual-effect Energy-saving Central AC: High cooling performance with excellent energy efficiency for general manufacturing workshops.

Dust Removal Central AC: Equipped with primary/medium filters and water curtain dust removal modules for dusty environments like powder printing, metal and building material production.

Odor Removal Central AC: Pre-installed low-temperature plasma purifier rapidly decomposes VOCs and odors from printing and chemical processes.

Lint Removal Central AC: Built-in automatic lint collector, ideal for textile and garment workshops with floating fibers.

Air-bearing Chiller: Adopts aerodynamic gas bearings, high-efficiency permanent magnet synchronous motors, two-stage compression and subcooling technologies. Oil-free, efficient, stable, quiet and eco-friendly, reaching internationally advanced level.

Aircraft Ground Air Conditioning Unit: Internal combustion type for civil and military aircraft ground support. Built on Class II chassis with Cummins diesel generator, Siemens S7-1200 controller and R410A eco-friendly refrigerant.

Cross-industry Application Capability

Our solutions serve 13 major sectors: printing & packaging, textile & apparel, electronics, toy manufacturing, injection molding, food processing, machinery, CNC precision machining, PCB cleanrooms, automobile manufacturing, livestock farming, protected agriculture and airports. Whether facing high heat, heavy dust, odor, floating fibers or strict cleanliness requirements, Dongke provides integrated temperature control and air treatment solutions to meet production standards while maximizing energy savings.
