Rising energy costs have made hydraulic system efficiency a necessity rather than a
choice.
A
correctly optimized hydraulic system not only lowers energy bills but
also
extends component life, reduces failures, and shrinks your carbon footprint.
Striking Statistic
Approximately 15-20% of total energy consumption in
industrial facilities comes from hydraulic and pneumatic systems. It is possible to
achieve
up to 30% savings with efficiency-focused modernization.
1. Key Factors Reducing Efficiency
There can be many reasons for a system's inefficient operation. Energy loss usually
turns
into
heat, which increases the cooling load of the system, creating a "double damage".
1.1. Over-sizing
Electric motors and pumps chosen larger than necessary with "just in case" logic always
operate
below the optimum efficiency point. This unnecessarily increases both the initial
investment
cost and operating expenses.

2. Transformation with Modern Technologies
Transitioning from traditional fixed displacement systems to modern technologies can
shorten
the
return on investment (ROI) surprisingly.
2.1. Load Sensing Systems
Load sensing pumps produce only the flow and pressure the system needs. In standby
states
where
there is no load, energy consumption drops to almost zero.
2.2. Variable Frequency Drives (VFD)
Inverter systems that adjust the speed of the electric motor according to hydraulic
demand
are the
pinnacle of energy saving. Motor speed idling at fixed speed is becoming history.

3. Heat Management: The Hidden Energy Thief
Heat = Lost Energy
If your hydraulic system is operating above 60°C,
something is
wrong. Excessive heat is the most concrete evidence of lost energy spent in the
system
but not
converted into work.
Heating problems usually stem from either insufficient cooling capacity or (more often)
unnecessary pressure drops in the system. As BRS PROSES, we detect "hot
spots" in
your system with thermal camera analysis and eliminate the source of inefficiency at the
point.
