Precise High-Low Temperature Control UnitAlso known as a high and low temperature circulator, a heating and cooling unit, or a high and low temperature circulation unit, it is specifically designed for heating and cooling reaction vessels. The entire circulation system of the high and low temperature unit uses a fully enclosed circulating heat transfer medium. The circulation system includes a liquid expansion vessel, which is a separate system from the liquid circulation. The expansion vessel does not participate in the liquid circulation but is mechanically connected. Even during high-temperature operation, the heat transfer medium in the expansion vessel will not exceed 50 degrees Celsius.

High and Low Temperature Integrated MachineFor bioproducts and chemical industries, the low-temperature cooling liquid circulating pump is a low-temperature liquid circulating equipment using mechanical refrigeration. It provides a constant pressure circulation of cooling liquid to meet the need for lowering the operating temperature of equipment like reactors. For instruments that require constant flow and pressure water cooling in areas with limited water sources, poor water quality, or high temperatures, this machine is essential for ensuring normal operation of the instruments.

WhenHigh and Low Temperature UnitThe glass reactors, reactors, rotary evaporators, and extraction equipment supplied can quickly reach the set temperature when a rapid increase or decrease in temperature is required. The equipment allows for quick switching between heating and cooling, using the same medium (heat transfer oil), thereby eliminating the previous drawback of requiring two separate instruments for heating and cooling. The entire liquid circulation of the high and low temperature cycling unit is sealed, with an expansion vessel that is insulated and does not participate in the liquid circulation; it is merely mechanically connected. The medium in the expansion vessel remains below 60 degrees Celsius, regardless of the temperature of the liquid circulation. The entire liquid circulation is also a sealed system, ensuring no moisture absorption at low temperatures and no oil mist generation at high temperatures. The original heat transfer oil compatible with this product has a broad market; the entire circulation system is sealed with no leaks.
