Under the development of Industry 4.0 era, many universities and research institutes have begun to pay more attention to the scientific experimentation and fabrication. More and more applications require a precise heating and cooling process. Therefore, the need for accurate temperature adjustment gradually becomes important. INNOTEG TCS-3 Laboratory Refrigerated Circulator was born to fully meet the urgent needs above.

Early history

In 1748, artificial refrigeration was demonstrated for the first time by William Cullen of Glasgow University, UK.

In 1851, the first ice-making machine was invented by John Gorrie. Ice baths quickly became a popular way of cooling reactions and other lab processes, and this low-tech technique is still frequently used today.

In 1876, a continuous process of liquefying large volumes of gas was invented by the German engineer Carl von Linde. This invention eventually made chilling and refrigeration possible on a domestic and industrial scale and laid the groundwork for the development of the modern refrigeration industry.(1)

Refrigeration principle

Refrigeration is the process of removing thermal energy (or heat) from a low temperature reservoir and transferring it to a high temperature reservoir requiring the input of energy. A fluid or refrigerant repeatedly circulating through the refrigeration system’s components accomplishes the heat transfers. One complete circulation of the refrigerant completes a cycle.

Basic refrigeration cycle

Vapor compression refrigeration systems contain at least four components: evaporator, compressor, condenser, and an expansion device. At each location in the vapor compression cycle, the refrigerant maintains its operating condition under a steady-state operation. Vapor compression systems are prevalent in refrigeration applications, but in special situations absorption refrigeration cycles may be preferred. The coefficient of performance (COP) is a measure of how well the refrigeration cycle is using the supplied energy to provide refrigeration.(2)

Modern laboratory refrigerator

Today, recirculating chillers are increasingly improved to optimize the important factors such as instrument capacity, material durability, user controller and even size & weight. However, accurate temperature control is still the most important element.

Most of application requires a high degree of temperature accuracy. For evaporation process, exact temperature levels at the condenser equal success or total failure. That is why INNOTEG TCS-3 Laboratory Refrigerated Circulator was born. The instrument is equipped with the most advanced features to make it the right tool for the most demand applications.

TCS-3 advantage points

Excellent Temperature Control: TCS-3 offer proportional cooling control to ensure energy saving performance.

Efficient Circulation Mode: Pressure suction pump is used to reduce the frequency of maintenance, long life time and no limitation of circulator location.

Ease of Control: Temperature and flow rate can be controlled separately. Liquid level can be monitored by bath level indicator located at right hand side of circulator.

Safe and Protective Design:

  • Automatic pressure control provides stable pressure to connected equipment
  • Water-proof and soft touch control panel
  • LED display
  • Memorize the previous setting

Flexibility: Heater as option to provide high temperature circulation.

INNOTEG TCS-3 Laboratory Refrigerated Circulator, fully made of stainless steel and suitable for rotary evaporator, polarimeter, electrophoresis apparatus and continuous flow analyzer, is your economic choice for reliable operation in laboratory.
