DBP Series

Blower-type
desiccant air dryer

DBP Series can operate at below -40°C of dew point temperature under operating pressure,
10.7N㎥/min of processing capacity and 10 kgf/㎠ of operating pressure. We can produce equipment larger than the above standard model and it is also possible to have them replaced or combined.

DBP Series

Product Features

Based on basic temperature sensor system and optional moisture sensor system,energy usage is appropriately adjusted depending on the load.
Energy requirement is minimized by adopting insulation tower, piping, high efficiency heater and air blower.
Reduces energy loss by minimizing regeneration air
Dew point is guaranteed even at 100% load cycle.
PLC control is utilized to monitor all dangerous operating conditions, display operation status and malfunction conditions on the display or touch screen panel, and control the operating procedures of valves, heaters and blowers.

Model Selection and
Calculating Working Volume Flow Rate

MODEL : DBP-750

What’s the working volume flow rate when inlet temperature is 40°C with inlet pressure of 5kgf/㎠ ?
Standard working volume flow rate of DBP-750: 22 N ㎥/min
Conversion Coefficient for 40°C of temperature: 0.9
Conversion Coefficient for 5kgf/㎠ of pressure: 0.75
* Working Volume Flow Rate = 22 N㎥/min x 0.9 x 0.75 = 14.85 N ㎥/min
Which model should be used when working volume flow rate is 35 N㎥/min with 45℃
of inlet temperature and 8 kgf/㎠ of inlet pressure ?
Adjusted working volume flow rate under standard Condition.
(38℃ of inlet temperature, 7kgf/㎠ of inlet pressure)
= 35 N ㎥/min / 0.7 (Conversion Coefficient for temperature) / 1.12 (Conversion Coefficient for pressure)
= 44.64 (N ㎥/min)
* DBP-1750 on the working volume flow rate index by model.
