Comparison project	Original shell and tube type cold dryer	Energy-saving plate type cold dryer
Volume flow	85Nm³/min	85Nm³/min
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	16℃	4.8℃
Nameplate power	13.5kW	8.2kW
Measured current	21.8A	13.5
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".
