Aluminum-wood composite doors and windows are known for their excellent thermal insulation, energy efficiency, and resistance to sand. These windows feature a solid wood core with an additional layer of broken bridge aluminum alloy on the exterior, which enhances their sealing properties and effectively prevents sandstorms from entering. In extreme heat, they can block outdoor heat, reducing the loss of indoor cooling. During cold winters, they prevent condensation and keep noise out, ensuring a comfortable living environment.
(1) On the exterior side, special aluminum alloy extrusion profiles are used, with a fluorocarbon coating that resists UV rays and natural corrosion. This allows for a wide range of color and pattern options, giving homeowners flexibility in design. The interior features high-quality wood processed through advanced craftsmanship, and the wood surface is coated with premium German paint, offering UV resistance, water resistance, and excellent anti-corrosion performance. It is eco-friendly and maintains minimal deformation due to its specialized profiles. These doors and windows can match various interior styles, enhancing the overall aesthetic with a modern and American-style appearance. The wooden profiles on the inside also help block thermal bridges, significantly improving energy efficiency.
(2) Multi-channel sealing systems are employed, using an isobaric chamber design typically found in high-end curtain walls. This ensures superior waterproofing and sealing performance, surpassing that of standard aluminum or high-grade PVC windows.
(3) The glass section uses hollow glass with a decorative trim strip made using American technology. This provides better aesthetics, insulation, and soundproofing compared to traditional aluminum trims used in most domestic windows.
(4) High-quality German hardware is integrated into the system, offering stable performance, durability, and a smooth opening and closing experience.
(5) The installation method follows a sub-frame-first approach, ensuring high precision and superior construction quality. The sub-frames are made from treated wood, and the German-style window frames are fixed to ensure structural integrity and enhanced waterproofing.
(6) A mesh screen can be installed either indoors or outdoors, fitting tightly with the window frame for effective mosquito control. It is easy to remove and clean. The screen frame is made of wood, blending seamlessly with the overall design and maintaining a cohesive look.
An oxygen concentrator is a device used to generate and supply oxygen, and is widely used in the fields of medical, home healthcare, industry, and scientific research. Here are some of the main features and properties of oxygen concentrators:
Main features
Oxygen concentration
Medical-grade oxygen concentrators: They can usually provide up to 90%-95% oxygen concentration, suitable for patients with oxygen needs.
Home Oxygen Concentrators: They can generally provide more than 90% oxygen concentration, suitable for daily home healthcare.
Industrial oxygen concentrators: Oxygen concentrations may be higher to meet industrial production needs.
Flow rate
Low-flow oxygen concentrators: Usually 1-5 liters/minute, suitable for home and mild oxygen therapy needs.
High-flow oxygen concentrators: Flow rates can reach 10 liters/minute or more, suitable for critically ill patients or special medical needs.
Noise level
Modern oxygen concentrators are designed with a low noise level, usually between 40-60 decibels, to ensure comfort when used in home and medical environments.
Energy consumption
Oxygen concentrators are generally powered by electricity, and energy efficiency and power consumption vary depending on the model. Energy-saving oxygen concentrators can reduce operating costs.
Portability
Portable oxygen concentrator: small size, light weight, suitable for carrying around, suitable for outdoor or travel use.
Desktop oxygen concentrator: suitable for use at home or in a fixed location in a hospital, usually more stable and reliable.
Ease of operation
Equipped with a simple and easy-to-understand control panel and display, some models have remote control functions, which are convenient for users to adjust parameters and monitor status.
Safety
Equipped with multiple safety protection mechanisms, including overheating protection, overvoltage protection, hypoxia alarm and other functions to ensure safety during use.
