Energy Saving Transformation Case


Comparison project

Original shell and tube type cold dryer

Energy-saving plate type cold dryer

Pressure drop

The new machine is 0.55bar, 1.2bar half a year later, and 1.7bar two years later. The inside and outside of the pipeline are rusted, and the user is scrapped for reconstruction

0.23bar (including filter), still 0.25bar after 7 months

Pressure dew point

4.8℃

Nameplate power

13.5kW

8.2kW

Measured current

21.8A

Cooling water flow

13.5T/h

7T/h

Control

On site start stop, employee complaint

Remote, chain, communication



Performance analysis:

The pressure drop at the inlet and outlet of the whole machine is only about 0.01Mpa, which means that the air compressor can be set with lower exhaust pressure;


Pure countercurrent heat exchange system, air inlet and outlet temperature difference of 10 ℃. The regenerative system recovers 40% more cooling capacity than the traditional shell and tube dryer, which is the fundamental reason for energy saving of plate exchange dryer. Under the same working condition, it can save more than 30% energy and truly achieve "low dew point" and "low energy consumption".
