Basic knowledge of temperature control equipment

The temperature control device is a circulation device that can provide a cold source or heat source, which can provide stable cold and heat source output and temperature control for the application instrument, and the application is very wide.

The temperature control products mentioned in this article mainly refer to small temperature control devices used in experimental instruments, and the main uses are supporting rotary evaporators, reaction kettles, or reaction vessels
such as cooling and heating beakers, flasks and test tubes.

It is mainly used in universities, enterprise laboratories, pharmaceutical and biological research institutes, etc
.

The classification of the company's temperature control products: According to the different functions, it can be roughly divided into four categories: First, the CC series (cooling circle) cooling circulator single cooling, temperature -20 to room temperature, temperature control accuracy ± 2 degrees, mainly used for spin steaming and reactor condenser
.

Second, the HC series (heating circle) heating circulator single heating, temperature room temperature to 200 degrees, temperature control accuracy ±0.
5, mainly used for reactor kettle body heating
.

Third, DTC series (dynamic temperature control) dynamic temperature control device has both refrigeration and heating, the overall temperature range -80 to 200 degrees, temperature control accuracy ±0.
5, mainly used for reactor body heating, cooling
.

Fourth, CTS series (constant temperature stir) low temperature constant temperature reaction bath at the same time cooling and heating, the overall temperature range of -80 to 100 degrees, temperature control accuracy ± 0.
5, there are open baths and stirring, mainly used for test tubes, flask beakers and other reaction vessels of constant temperature, stirring
.

Cc series (cooling circle) cooling circulator: This is a single refrigeration circulator that can provide continuous low temperature conditions for external equipment, the use temperature range is -20 degrees to room temperature, the actual no-load temperature can be lower than -20 degrees, and the temperature stability ± 2 degrees
.

It is mainly used to support rotary evaporators and reactors (connected to their condensers), but also to provide a cold source
for other external equipment.

CC-400 CC-1000 artificial consumption of a certain amount of energy (work, electrical energy, etc.
) method to obtain a lower temperature than the environment, is called "refrigeration"
.

There are many methods of refrigeration, including vapor compression, absorption, vapor jet, thermoelectric refrigeration and so on
.

Among them, vapor compression refrigeration (compressor refrigeration) is widely used, and our company's refrigeration equipment uses this refrigeration method
.

Cooling capacity: The heat absorbed during the time, generally expressed
in KW or W.

The lower the evaporation temperature, the smaller
the cooling capacity.

When expressed as "horses", it is only an approximate value
.

Under air conditioning conditions (evaporation temperature 7.
2 degrees), one horse is equal to about 2500W
.

The number of compressors can also be converted into electrical power, and the electric power of 1 compressor is about 735W
.

Steam compression refrigeration principle: the use of refrigerant from the liquid state vaporized to vapor state in the process of absorbing heat, the cooling medium due to the loss of heat and reduce the temperature, to achieve the purpose of
refrigeration.

Advantages of the company's CC series cooling circulator: *CC-400 adopts stainless steel coil evaporator, which has good corrosion resistance and scale resistance, high strength and long
life.

Other models adopt plate heat exchanger, high heat transfer coefficient, small heat loss, high heat exchange efficiency, compact
structure.

*CC-400 and above models use fully enclosed reservoirs and circulation lines, which reduce the exposure of ethanol and other refrigerants to volatilization or combustion in the air, which is safer, less loss, and faster
refrigeration.

Optimized pipeline design, the amount of carrier refrigerant used is only 30% of traditional open refrigeration equipment, saving the cost
of use.

* All use fluorine-free refrigerants that meet international environmental protection standards, green and low energy consumption operation
.

* Magnetic circulation pump, from dynamic seal to closed static seal, to avoid media leakage
.

*Adopt fully enclosed compressor, low noise, high efficiency, to ensure long-term stable operation
.

*The part in contact with the liquid is made
of 304 stainless steel or high quality plastic.

* Simple and convenient touch screen operation, while displaying the reservoir temperature and set temperature, setting the temperature is convenient
.

* High safety, shell and other potential connection to prevent electric shock, there is delay, overheating, overcurrent, leakage protection
.

* All models have special liquid discharge valves, which is more convenient for
liquid discharge.

Second, HC series (heating circle) heating circulator HC series is a single heat circulator that can provide continuous high temperature conditions for external equipment, using a temperature range of room temperature to 200 degrees, and the temperature stability ± 0.
5 degrees
.

It is mainly used for supporting reactors, connecting reactor jackets for heating, and can also provide heat sources
for other external equipment.

Advantages of the company's HC series heating circulator: * Temperature control adopts PID mode, and the control accuracy is high; * Adopt high temperature circulation pump with higher flow and pressure, and the heat exchange effect is better
.

* Fully enclosed expansion system and circulation system, to prevent the heat transfer oil from contacting the air oxidation or water absorption deterioration and affect the stability of temperature control, prolong the service life of the heat-carrying fluid, and the closed system has high
safety.

* Optimize the pipeline design, the heat agent in the expansion box does not participate in the circulation, the amount of dosing and heat loss is small, and the use of tubular heaters makes the heating speed faster
.

* More compact structure design, small size of the whole machine, reduce space occupation
.

*Equipped with standard Modbus RTU protocol RS485 communication interface, can be remotely controlled for temperature control and data reading
.

*There is a filter device in the circulation line to prevent the circulation line from clogging
.

* The part in contact with the liquid is 304 stainless steel, with liquid level display, discharge valve
.

* High safety, shell and other potential connection to prevent electric shock, leakage, overcurrent, high temperature protection
.

* Heating triple safety protection: system itself control protection, AC contactor front power protection, independent mechanical temperature control switch

Third, DTC series (dynamic temperature control) dynamic temperature control device: This equipment can provide continuous low temperature or high temperature conditions to external application equipment, constant temperature accuracy is relatively high, common temperature range -80 degrees to 200 degrees, general temperature temperature ± 0.
5 degrees
.

It is mainly used to match the reactor, and the connection reactor sandwich provides a constant low temperature or high temperature environment
to the kettle body.

It is also possible to provide a hot and cold source
for other external devices.

You can select the equipment outlet temperature or the material temperature in the kettle as the temperature control object
.

Fourth, CTS series (constant temperature stir) low temperature constant temperature reaction bath: this equipment can provide continuous low temperature or high temperature conditions to external application equipment, constant temperature accuracy is relatively high±0.
5, common temperature range -80 degrees to 100 degrees
.

It is often used for stirring and constant temperature of reaction vessels such as test tubes and beakers, and can also provide cold and hot sources for other external equipment with external circulation function, which is more versatile
.

The CTS series is based on an open cooling circulator with the addition of heating tubes
in the bath.

The heating tube is hedged with the refrigeration system to ensure constant temperature accuracy, and there is a magnetic stirrer at the bottom of the bath, and the stirrer is placed in the reaction vessel to rotate and stir
