At Sunrecipe, we specialize in manufacturing smart, flexible, and clinically effective targeted light therapy devices—designed to meet the rising demand for natural pain relief and recovery solutions. What Is Targeted Red Light Therapy? Target Therapy in red light treatment refers to the application of precisely controlled red and near-infrared light to specific areas of the body—such as the lower back, knees, abdomen, or shoulders. By focusing light energy (typically 630nm–850nm) directly on problem zones, this therapy stimulates mitochondrial activity, enhances blood flow, reduces inflammation, and accelerates tissue repair — all without drugs or invasive procedures.

DUCT CORNER Duct corners are essential components in HVAC duct systems, specifically designed for securing the corners of rectangular or square ducts. These parts play a critical role in ensuring the structural integrity and air-tightness of air duct connections, especially when used in conjunction with flange systems like TDC or TDF. At Beiouli Metal, we offer a wide range of duct corner types including 30mm, 35mm, 40mm, and 45mm models to match various duct flange sizes. Manufactured from galvanized steel or stainless steel, our duct corners feature high strength, corrosion resistance, and precise dimensions for easy and secure installation.

Vacuum environment simulation In the thermal vacuum test, the first step is to simulate the vacuum environment of space. When spacecraft operate in space, there is almost no air around them, meaning they are in a high vacuum state. To simulate this environment on the ground, a vacuum system is used, including vacuum pumps, gas condensers, and pressure sensors, etc. The gas inside the test chamber is evacuated to make the internal pressure approach the vacuum state. Usually, the vacuum requirement of the thermal vacuum test is better than 6.5x10^-3 Pa to ensure that the simulated vacuum environment is close enough to the real space environment.If you need more models about our test equipment, please reference our ： https://www.chamber-testing.com/ Temperature cycling simulation In space, spacecraft undergo significant temperature changes because they are exposed to solar radiation and cosmic darkness. The thermal vacuum test simulates these temperature cycles through heating systems and cooling systems. The heating system can use resistance wires, radiation heaters, or high-frequency heaters, etc., by controlling the current and voltage of the heating elements to regulate the temperature. The cooling system may use low-temperature media such as liquid ammonia. During the test, the spacecraft is heated to a high temperature (for example, +65°C) and cooled to a low temperature (for example, -35°C), and cycles between these extreme temperatures to test its performance under temperature changes.

A vacuum test chamber is a type of testing equipment capable of simulating specific environments. As an important type among them, the thermal vacuum test chamber is a comprehensive testing device that simulates high vacuum and alternating high and low temperature environments. It can simulate the real state of products in the usage environment and test the performance and reliability of products under high temperature, low temperature and vacuum conditions. It is mainly used for reliability testing and performance verification of products such as spacecraft components, satellite modules, precision electronic instruments, and optical devices. The thermal vacuum test chamber mainly simulates a high-temperature and high- vacuum environment through the coordinated action of a vacuum system and a heating/cooling system. The vacuum system expels the gas in the vacuum chamber through components such as vacuum pumps, gas condensers and pressure sensors, bringing the internal pressure close to a vacuum state. The heating system is usually composed of resistance wires, radiant heaters or high-frequency heaters, etc. The heating power and temperature are regulated by controlling the current and voltage of the heating elements. In practical operation, a high vacuum environment is formed by the combination of a main pump (such as a mechanical pump) and a molecular pump to evacuate the vacuum chamber. The heating system heats or cools the chamber through electric heating wires or liquid nitrogen, creating a uniform temperature field in the heat sinks of the chamber, simulating a space environment with both vacuum and a wide temperature range (such as -100℃ to 125℃).If you need more information about the models of our testing equipment.
