GDSZ-5 series Refrigerated & Heating Circulators belongs to high and low temperature oil bath circulation device, according to the specific test environment. GDSZ-5 series Refrigerated & Heating Circulators is a new generation of products which is researched and developed on the basis of DLSB low temperature cooling liquid circulating pump and GY oil bath, with the function of one machine with multiple, and widely used in small space with a variety of specific environment.
Through data programming for the equipment of intelligent temperature controller, by temperature sensing system feedback container temperature data, the controller control the compressor to make cooling, let the medium in the cold trough get low temperature; through the heater heat, so that the medium in the tough can obtain high temperature, by rapid thermal process, it can let medium temperature in the tough suiting for user needs, then through the absolutely leakage shielding circulating pump transfer the medium to an external device (such as a reactor). After the re-flux is switched, turn on the valve, the purpose of heat circulation can be achieved.
Features of GDSZ-5 series Refrigerated & Heating Circulators:
1.When the temperature of glass reactor, reactor, rotary evaporator, extraction equipment which is equipped with GDSZ-5 series Refrigerated & Heating Circulators need rapid heating or cooling, the equipment can quickly reach the set temperature.
2.The equipment heating and cooling can be quickly converted, the using medium (heat transfer oil) is the same kind of medium, it completely improves the drawbacks of using two units instrument to complete heating and cooling in the past.
3.GDSZ-5 series Refrigerated & Heating Circulators, its whole liquid circulation is closed, with expansion vessel, expansion tank and liquid circulation is adiabatic and does not participate in the liquid circulation, it is only the mechanical connection. No matter the liquid circulation temperature is high or low, the medium in the expansion container is lower than 60 degrees. The whole liquid circulation is a closed system, it can be done at low temperature without water vapor absorption, high temperature without oil mist generation.
4.The original heat conducting oil temperature field matched GDSZ series of products is very broad (low temperature of 40℃ to high temperature of 200℃); the entire circulatory system closed without leakage.
It is widely used in colleges and universities, environmental protection, biochemical, medical, chemical industry, scientific research, biological industries etc.
