FD系列低温箱是化学，物理，生物，医学，冶金工业，仪器仪表电器行业等领域中，从事低温科研，生产的重要检测，培养，食品速冻等领域。
       FD系列低温箱箱体外壳采用聚胺脂整体发泡，保温性能好，箱体有立和卧式两种，箱体外壳采用喷塑彩钢板，内胆工作室采用ICr18Ni9Ti,工作温度为－40℃，－60℃，℃，－80℃。工作室容积为200L，400L，600L。系统均有超压、过流保护；特别在低温双级机中利用智能温控仪使开机能保证高温机蒸发温度在一定温度下，低温机才能起动。并且在运行过程中保证高温机先开后停，低温机后开先停。同时大量减少电器零件，提高运行可靠性。由于本公司采用*发泡工艺，故工作容积、尺寸及形状均可按用户需要制造。
        FGD系列高是在FD系列上进一步配置电热管，更能扩大使用范围。公用一个转换开关，即可使用。

FD series is the main device for researching, producing in lower temperature whichwidely used in the field of chemical, physical, biology, medicinal, metallurgy, instrument, electrinal. It can be used for cryogenic store, test, inspection, and food deep freeze.
    FD series cryostat have a good performance of temperature prevention by adopting polyurethane wholly frothing up. There are two types of cabinet:vertical and horizontal. The shell of cabinet is made of spray plastic color steel which inner using Icrl8Ni9Ti. The working temperature is –40℃，-60℃，-80℃. The  working volume is 200L, 400L, and 600L. It has over voltage and over currency protection. Especially in low temperature double temperature control system, The inligent temperature controller can gusrantee high temperature machine at the certain temperature, then low temperature machine stan. Meanwhile, it can ensure high temperature machine first stah last close, low temperature machine later ster, forth lose. The running reliability is improved by reduced amount of electrical componced. FD series adopting advanced frothing up mothed, so the working room volume, size and appearance can be made to customer’s demand.
    FGD series high-low the FD series, It can easy to use only push convert switch.
