The circulating oil bath pot is a circulation and constant temperature heating device designed and produced with a fully stainless steel shell. It has the characteristics of compact and reasonable structure, safe and convenient use, precise temperature control, controllable output flow, and energy-saving. It can conveniently provide a circulating constant temperature heat source for laboratory equipment such as single and double layer reaction kettles/jacket reaction kettles/rotary evaporators/glass reactors/vacuum reactors.
◆ Sanitary grade stainless steel plate material is used as the inner liner. The shell is made of high-quality cold plate electrostatic spray molding. The electric heater is placed in the center of the pot bottom, which has the advantages of fast heating, high heat efficiency, low power consumption, and safety without leakage. The interlayer between the oil bath shell and the inner and outer walls is filled with insulation cotton, which has a good insulation effect.
◆ The built-in circulating pump exclusively adopts an efficient heat dissipation packaging design, ensuring the continuity of instrument operation. The pump head is made of high-temperature resistant insulation material, the pump core is made of high-temperature bearings, fluorine rubber oil seals, anti-corrosion and high-temperature resistant, and the oil outlet and inlet are made of cast copper valves. Install universal corner wheels at the bottom of the machine for convenient use.
◆ Optimize the temperature control system by adding controllable silicon (below 3KW) or solid-state relay (above 3KW) as the heating control core for both digital and meter displays. The principle of controllable silicon is to adjust the voltage and temperature by relying on the weak current signal of the instrument. Solid state relays rely on the micro voltage signals of the instrument to turn on and off as switch outputs, thereby achieving control of the output terminal of the heater.
◆ The temperature sensing part of the instrument adopts a K-type armored platinum resistor, and the envelope adopts a copper tube coating process, which has fast heat conduction. Platinum resistance sensor is a high-end temperature measurement product with the characteristics of small resistance value and high accuracy.
The air-cooled circulating oil bath is a circulating and constant temperature heating device designed and produced on the basis of the high-temperature circulating oil bath. It can be used alone or as a water bath or oil bath for rotary evaporators, as well as a water bath, oil bath, circulating water bath, circulating oil bath, air-cooled circulating water bath, or air-cooled circulating oil bath for reaction kettles. You can choose according to your needs.
The air-cooled circulating oil bath adopts a stainless steel shell, and the heating device has advantages such as fast heating, uniform temperature, compact and reasonable structure, safe and convenient use, precise temperature control, fast cooling speed, controllable output flow, and energy saving. This device is equipped with an air-cooled rapid cooling device, which can quickly lower the high-temperature medium to room temperature, greatly saving the experimenter's time and cost. The inner liner is made of imported stainless steel plate material. The electric heating tube is located in the middle of the oil, with fast heating, high thermal efficiency, low power consumption, and electronic constant temperature. The temperature control system of the product has also been improved, with temperature control devices added to both digital and meter displays. There is a thermal insulation cotton protection between the outer shell and inner liner of the oil bath, providing excellent insulation effect.
