Wuxi Guanya Refrigeration Technology co., ltd

We are LNEYA, a manufacturer of chillers

LNEYA chiller manufacturer is committed to the R&D, production and sales of refrigeration and heating temperature control systems, ultra-low temperature freezers, new energy automobile component testing systems, and heating cycle systems. The products are widely used in low-temperature reaction fields in the chemical, pharmaceutical, biochemical and other industries, with fast refrigeration speed, safety and reliability.


It has a research and development team of highly qualified professional designers with rich experience in ultra-low temperature, high and low temperature development. The company is currently at the advanced level in the same industry in the research and development of stand-alone cascade refrigeration technology, and is at the international advanced level in the research of high and low temperature rapid temperature rise and fall technology. In particular, the high-precision temperature control of the reactor is the internationally advanced single-medium control -90℃~+250 continuous temperature control, and the temperature of the reactor material is linearly controlled with high precision. The product temperature ranges from -152°C to 350°C.


Our temperature control equipment adopts computer cascade temperature controller and PT100 temperature sensor. The product adopts ethylene glycol and water mixture for circulating cooling to save water resources; the refrigeration equipment adopts supercooling technology to ensure temperature stability at low temperatures; adopts a fully enclosed design to ensure the purity of the cold heat transfer medium, prevent ice crystals, and improve the heat transfer fluid life.


Typical applications of the SUNDI series of refrigeration and heating temperature control systems: dynamic constant temperature control of cold and heat sources of various reactors, constant temperature control of cold and heat sources of micro-channel reactors; small constant temperature control systems, temperature control of steaming systems, material low temperature and high temperature aging test, vacuum Room cooling and heating thermostatic control, etc. Ultra-high temperature cooling technology can directly refrigerate and cool from a high temperature of 300 degrees (because only the heat transfer medium in the expansion cavity is in contact with oxygen in the air (and the temperature of the expansion tank is between normal temperature and 60 degrees), which can reduce the heat transfer medium Risk of oxidation and absorption of moisture in the air. No heat transfer medium evaporates at high temperature, and continuous control of -80-190 degrees, -70-220 degrees, -88-170 degrees, -55-250 degrees, -30-300 degrees can be achieved without pressurization. temperature.


If you belong to the chemical and pharmaceutical experimental production industry, you will definitely need the assistance of temperature control equipment during the reaction process. You can consult our LNEYA chiller manufacturer on the technology and use of industrial temperature control systems.
