[By NBC-1TV H. J Yook]DOTECH Inc., (CEO Duk Nam Choi, www.dotech21.com) a manufacturer specialized in industrial machinery (equipment) control system, released digital pressure switch DPX200 that is used for refrigeration parts on September 1 this year.

It is possible to install this product easily by applying the “digital all in one type” that unites the existing high and low pressure switch, the high pressure fan switch and the gauge of high and low pressure. It is also possible to reduce the administrative costs and a variety of effects compared to the conventional analog switch method.

In particular, DOTECH Inc. has presented a perfect solution to prevent leakage of refrigerant gas that is the biggest problem in the operation of the refrigerator by the company’s proprietary technology.

As for the existing analog type pressure switch, there was a disadvantage that it would be difficult to check the operation of the pump because of low reliability of the set values as the pressure value changed at each measurement.

On the other hand, since DPX200 can determine changes in the pressure value via the sensors dedicated to the refrigerant, it is able to do even the measurement and adjustment of the fine pressure. Also, since it can see exactly whether the pump is being operated or not, it is able to fasten the inspection time.

In addition, it is easy to control the fan and the on/off of power supply; thus, it is possible to apply it to various types of refrigerant such as refrigeration plant, air conditioning for industrial/home use, small and medium-sized refrigeration systems, etc.

Moreover, it was made to express changes in the saturation temperature of refrigerant and the pressure value as a large point as being equipped with the FND display. And it is able to adjust the height through the “bracket” that is a stand-up as taking care of the convenience of users.
