Differential pressure monitoring in compressed air systems
ΔP-minimization through timely element change saves energy and filter costs
Filters ...
- are only expensive resistances from an energetic point of view
- should be avoided if possible - only as much as necessary-
- differential pressure on the central filter is to be monitored
Differential pressure monitoring on filters with Airleader
Example
filter dimension: 2 “ - Filter (DN 50)
Too much pressure loss Δp on the filter: 0.25 bar (0.35 instead of 0.10 bar)
Flow rate through the filter: 4 million m³/a (≈ 75 kW compressor, 6,000 operating hours/a)
Additional energy consumption of the compressor (manufacturer data sheet):
=> 5 kW additional consumption per bar higher compression
= 5 kW x 0.25 x 5,437 Lh x 0.2 €/kWh
= € 1,360.- every year
More - Energy costs per year: € 1,360 due to too much pressure loss!
Filter element costs for 2" filters: € 200
Excessive differential pressure is recognized by airleader and reported automatically
Requirements:
- airleader MASTER Modul
- Free analog input on the MASTER module or on the RS485 connection module
- Differential pressure transmitter Order no.: DP-1025(< € 500/piece)
Installation example: filter differential pressure sensor on MASTER module
