Program Freezer TF-PA-I

Program Freezer TF-PA-I

       Program freezer made by Tianfeng (nicknamed programmable cooler) is adopted with microcomputer control technology and special software, so the amount of liquid nitrogen can be controlled accurately to ensure that cryopreserved biological products can cool and freeze at proper freezing rate. The instrument is easy to operate and the human-computer interface is clear.

        田枫程序冷冻仪（俗称：程序降温仪）采用微机控制技术，专用软件，能较准确地控制液氮的施放量，从而保证被冻存的生物制品以适宜的冷冻速率降温冷冻。该仪器具有操作简便、人机界面清楚。

 2.Instrument structure

The instrument is made up of following four parts.(standard configuration)

(1)Microcomputer System: inner freezing control card, just running related software when freezing.

(2)Freezer: The freezer is made of stainless steel structure inside and outside. Freezing volume is not smaller than 200*200*200mm. The freezer can contain 160 cryovials and 8 blood bags in the same time.

(3)Liquid Nitrogen Container And Liquid Nitrogen Pressurizer: Liquid nitrogen pressurizer is installed on the 30m³ liquid nitrogen container to realize the self-pressurization in the container and maintain the pressure stability of control valve.

本仪器由以下四部分构成(标准配置):

微机系统: 内置冷冻控制插卡,冷冻时只要运行有关软件即可..

冷冻箱:  内外全不锈刚结构.冷冻容机不小于200*200*200毫米.可同时容纳冷冻管160个或血袋8个.

液氮罐及液氮加压器: 液氮加压器安装在30立升的液氮罐上,使罐内自增压,调节阀保持压力稳定.
