Programmable Temperature Controller TF-PA-III

Programmable Temperature Controller TF-PA-III
  • Model : Programmable Temperature Controller TF-PA-III
  • Brand :
  • Product ID :
  • Product Type : Industrial products series
  • Product Content :
Programmable temperature controller (nicknamed programmable cooler,program freezer,embryo freezer) 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.

Detailed

Programmable Temperature Controller TF-PA-III

 

     Shanghai Tianfeng is a professional manufacturer of programmable temperature controller,which is developed by retired researchers of Academy of Military Medical Sciences over twenty years. The software technology of the products is advanced, and it can perfect substitute  similar imported instruments.The instrument has been clinically used in many domestic hospitals over 10 years, which can better verify the property and stability of the instrument and gains admiration from customers.

     The principle of programmable temperature controller: The key 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 chemical 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.

   上海田枫是国内一家专业程控降温仪生产厂家.是由军事医学科学院退休科研人员经过二十多年研制而成的。本产品的软件技术先进,可替代同类进口仪器.并且通过国内多家医院十多年的临床使用,使仪器的性能及稳定性得到较好的验证,获得用户的好评.

   程控降温仪工作原理:关键就是液氮。液氮是一种惰性气体,压缩机加压,使其性质收到的压力超过20PA。当压力大于20PA时,液氮急速融合,化学性质非常活泼。程控降温仪有一个设置器(技术关键),可以把挤压的压力迅速排放到冷凝器,程控降温仪冷凝器迅速吸收冷量。这是的温度骤降对机器的要求,材料的选配和控制器的要求都是很高的。

 

1.Main technical indicators:

Model: TF-PA-III

Temp Control Range: 40℃~-180℃

Temp Accuracy: error within 0.5℃

Cooling Rate: in the range from 0.1℃/min to 50℃/min

Heating Rate:in the range from 0.1℃/min to 30℃/min

 

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.

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.

 

3.Software Function:

Start Minutes:0                                                      Stop Minutes:56.88

 

Programming Functions:

Any number of user programs can be programmed. Computer control freezing process according to user programs. User programs can program,revise,store and tune out easily. Current user programs can be tuned out automatically when starting up.

Run-time control function

Random constant temperature function: can in and remove a constant temperature at any time.

Manual functionManual control can take part in control during program control , and it can also be controlled by manual completely.

Keying function:can change cooling rate with keyboard to make temperature control great flexible.

Coordinate transformation function: X-coordinate and  y-coordinate can interconvert according to need.

Section into function: can skip current programs and go to next section at any time.

Data Processing Function

All the data and related information of every freezing can form a data file and be stored down automatically.

Temperature data and rate can be listed according to specified time or displayed temperature curves.

The software can retrieve bidirectionally the stored date files quickly and conveniently.

Temperature curve can magnify at local to research the subtle change of  critical sections.
Sorry that some other functions can not list, if these functions can be used cooperatively, it can bring great convenience in freezing.
