Embryo Freezer TF-PA-II

Embryo Freezer TF-PA-II

      How embryo freezer cool? The key here is liquid nitrogen. Liquid nitrogen is a kind of inert liquid. Pressurizing by compressor makes its pressure exceeds 20PA.. When pressure is larger than 20PA, liquid nitrogen fuses rapidly and its chenical property becomes very active.Embryo freezer has a setter(key technology), through which can let out extruding pressure into condenser rapidly and then the condenser absorbs cooling capacity quickly. Temperature dropping needs a high request of machine, material selection and controller. Because of company secrets, Tianfeng can only say proudly,we are the real leader in domestic embryo refrigeration industry. We can not only research independently in principle, but can also innovate and try bravely. We have achieved outstanding effect and applied for a patent.

      胚胎冷冻仪是如何降温的呢？这里的关键就是液氮。液氮是一种惰性气体，压缩机加压，使其收到的压力超过20PA。当压力大于20PA时，液氮急速融合，化学性质非常活泼。胚胎冷冻仪有一个设置器（技术关键），可以把挤压的压力迅速排放到冷凝器，胚胎冷冻仪冷凝器迅速吸收冷量。这是温度骤降对机器的要求，材料的选配和控制器的要求都是极高的。因为公司机密的问题，田枫公司只能自豪的说，我们在国内胚胎冷冻仪行业里是真正的翘楚。我们不但在原理上自主研发，还大胆创新用于尝试，取得卓越的效果，已经申请专利。
