Choose LNEYA precision chillers, choose your high-precision and high-stability cooling solutions. Our LT–45–precise cooling solutions chiller can provide a temperature control range of -45℃~30℃, a temperature control accuracy of±0.5℃, and a high-efficiency, energy-saving, and reliable experience with a cooling capacity of up to 4.8kW.

Our precision chillers use compressors for cooling, and then exchange heat with water to reduce the water temperature and send it out through a circulating pump.Its design and manufacturing can provide technical indicators and reliability that are superior to those of the same industry. It is a high-precision and high-stability cooling device. The LT -45℃ series cooling circulation device is a fully enclosed refrigeration system, combined with PID control, with fast cooling speed and stable temperature. It is suitable for some equipment that requires precise constant temperature cooling.

Get in touch with our Precision chillers experts

Our precision chillers use a compressor refrigeration system that exchanges heat with water to lower its temperature, which is then circulated by a pump. The temperature is controlled by a temperature controller, providing three functions: constant temperature, refrigeration, and circulation. The LX series uses non-stop refrigeration technology, offering superior technical specifications and reliability compared to industry standards. It is a high-precision, high-stability cooling device. The LX series cooling circulation system features a fully enclosed refrigeration system, combined with PID control for fast cooling speeds and stable temperatures, making it ideal for applications that require precise, constant temperature cooling.

Yes. Whether you have after-sales questions, need a pre-sales quote, or require custom services, feel free to contact us. We provide 24/7 professional and worry-free service.
Here is some feedback from our customers on our products.

Our precision chillers use secondary subcooling technology and inverter technology to help you achieve fast cooling. But LNEYA’s technical advantages don’t stop there. We hold over 80 technical patents, particularly excelling in cascade refrigeration technology and rapid temperature rise/fall technology, placing us at the international advanced level. Additionally, we have received numerous authoritative certifications, including CE certification, ISO9001 certification, SGS certification, industrial pipeline installation permits, explosion-proof equipment installation qualifications, and other relevant industry certificates.
