Through years of independent innovation, the company's low temperature products have obtained international certifications such as UL and CE. The existing products have been exported to Southeast Asia, Africa, Europe and America. As of 2018, our products have obtained more than 13 domestic patents. In 2018, the ultra-low temperature storage box produced by Qingdao Heli De Cryogenic Technology Co., Ltd. has applied the world's more advanced hydrocarbon refrigeration system, completely free of fluorine and zero pollution, and environmentally friendly. The cooling efficiency is increased by 30%, the power saving is half, and the temperature uniformity, cooling speed, holding time, noise and other indicators are superior to imported brands. Through calculation, a biological sample bank is 30 units, which can save 2 million yuan in 10 years, which greatly implements the new requirements of the state for creating "energy-saving" and "environmental" two-type society.
