Engineered to maintain strict thermal separation, dust-proofing, and energy efficiency in high-temperature, high-humidity environments.
Thailand's tropical climate presents severe challenges for indoor climate control. With high ambient temperatures averaging 30°C to 38°C year-round and relative humidity levels frequently exceeding 80%, commercial buildings, manufacturing factories, and cold chain logistics hubs face substantial energy loss and operational strain. When outer doors are opened for logistics, passenger flow, or shipping, the exchange of air is rapid: heavy, humid, hot air rushes in, while expensive cooled air escapes.
This is where high-performance air screens (air curtains) become an essential engineering requirement. By generating a continuous stream of high-velocity air across open doorways, air screens create an invisible, powerful barrier that isolates the indoor environment from external conditions. This barrier prevents up to 90% of heat transfer, moisture infiltration, and dust entry, ensuring that indoor HVAC systems operate efficiently without overloading.
Beyond thermal insulation, air screens in Thailand serve several vital regional functions:
Maintain a constant temperature for twenty years, creating a new future.
Dezhou Yuanxin Air Conditioning Equipment Co., Ltd. was established in March 2006, covering an area of 60,000 square meters. It is a comprehensive enterprise integrating the design, production, sales, and service of a series of products such as central air conditioning, ventilation equipment, CCCF fire smoke exhaust, etc. It is a member unit of the China Refrigeration Society, the vice president unit of the Central Air Conditioning Industry Alliance, a CCCF certified enterprise for fire protection products by the Ministry of Public Security, and a China HVAC production base.
In terms of equipment level, development space, and overall strength, the company has strong development potential. It has now obtained ISO9001, ISO14001, and OHSAS18001 (quality, environment, occupational health) three system certifications, obtained the national industrial product production license for fan coil units and air curtain machines, obtained the CCCF certification for fire protection products issued by the Ministry of Public Security's Fire Product Qualified Evaluation Center, and has national inspection reports for various series of main products, safety production standardization and other series of qualifications.

From high-tech cleanrooms in industrial zones to high-traffic commercial spaces in Bangkok, our products deliver optimal performance.
Luxury shopping centers and office towers in Bangkok experience constant pedestrian movement. Yuanxin's aesthetic card-type four-sided air outlets and low-noise centrifugal air curtains keep indoor air cool and comfortable while preventing the loss of air conditioning, leading to massive electricity savings.
In the automotive and electronics manufacturing bases of Chonburi and Rayong, maintaining clean, stable environments is critical. Our ceiling jet air conditioning units and high-induction vortex outlets guarantee dust-free cleanrooms, protecting sensitive assembly lines from contaminants.
Thailand's major logistics hubs require advanced cold-chain preservation. Yuanxin's heavy-duty industrial air screens seal logistics bays and cold rooms during continuous loading operations, preventing frost buildup on coils and maintaining agricultural and pharmaceutical product integrity.
Discover the full scope of HVAC and fire safety solutions manufactured at our 60,000 sqm production base.
Our state-of-the-art production lines utilize automated balancing and structural testing equipment to guarantee high-velocity airflow and minimal vibration, ensuring long-term durability in continuous-use environments.
Designed with high-quality copper tubes and hydrophilic aluminum fins, our fan coil units offer superior heat exchange rates and corrosion resistance, ideal for humid tropical climates.
Thailand's national commitment to the Bio-Circular-Green (BCG) economic model is driving industries to upgrade their facilities to reduce energy consumption and greenhouse gas emissions. In large commercial structures and factory buildings, the HVAC system represents up to 60% of total energy usage. As a result, developers are actively seeking advanced green building technologies to secure international certifications like LEED and local TREES (Thai's Rating of Energy and Environmental Sustainability) standards.
Yuanxin is at the forefront of this green transition. We are integrating advanced technologies into our air screen systems to meet modern energy-saving demands:
Thailand's extensive coastline and marine-adjacent industrial estates, such as Map Ta Phut and Laem Chabang, expose HVAC systems to salt-laden air, accelerating corrosion. Standard equipment quickly degrades under these conditions, leading to refrigerant leaks and structural failures.
To combat this, Yuanxin provides customized anti-corrosive treatments for all HVAC products destined for Thailand. Our coils feature specialized coatings, such as epoxy or hydrophilic blue fin technology, which prevent moisture accumulation and protect against salt spray. Additionally, casing materials are constructed from heavy-gauge galvanized steel sheet or stainless steel, finished with electrostatic powder coating to ensure resistance to rust and degradation over decades of service.
