Precautions for the selection of accessories for pharmaceutical refrigeration and heating circulators

1.
When the temperature control system of the reactor is connected to the controlled equipment, pay attention to the connection of the pipeline, the liquid outlet corresponds to the liquid inlet, and the liquid inlet is connected to the liquid outlet.
If it is a water-cooled equipment, the water outlet corresponds to the return water port , the water inlet corresponds to the water outlet, and the liquid discharge port (used when replacing the heat transfer medium) corresponds to the waste liquid recovery and collection port
.


2.
When selecting pipelines, if inappropriate/damaged hoses and/or hose joints are used, it will cause injury to personnel.
Carefully refer to its equal pressure and overpressure capacity, caliber, suitable temperature range
.

3.
When selecting thermal insulation materials, the temperature range of the temperature control system of the reactor should be considered first, and flame retardant materials must be selected.
The suitable temperature range of the thermal insulation material should include the temperature range of the equipment, and the thermal insulation material package of the reactor temperature control system should be sufficient.
, otherwise it may cause the device control to fail to achieve the expected effect
.

4.
It is necessary to consider the head pressure of the circulating pump inside the equipment.
Wuxi Guanya recommends that the temperature control system of the reactor should choose seamless steel pipes and other pipes with good quality and sufficient diameter as much as possible
.

5.
The pipeline connection between the temperature control system of the reactor and the controlled object should be as short as possible to reduce bending.
When the pressure of the circulating pipeline is too large and the pipeline pressure is insufficient, it will cause the pipeline and the reactor to crack.
, The possibility of high temperature and low temperature heat transfer medium spraying will cause the possibility of personnel explosion, scald, frostbite and ignition of flammable substances; the possibility of pollution, property damage, and even personal poisoning caused by the loss of reactants
