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.


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.




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.




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.



3.Software Function:

Display Function:

The running display is as shown in figure 11. Every operations and functions can be displayed on the screen. The working condition,three temperature data and curves can be displayed in real time.

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.

Software Upgrade

With constant upgrade of company software, users can enjoy free upgrade service.
