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

2. Transformation with Modern Technologies
Transitioning from traditional fixed displacement systems to modern technologies can
surprisingly shorten the return on investment (ROI).
2.1. Load Sensing Systems
Load sensing pumps generate only the flow and pressure required by the system. In
standby
situations 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 rotating in vain at constant speed is
becoming
history.
"Efficiency is not a one-time setting, but a continuous process. Even the most
modern
system will lose efficiency over time without periodic analysis."

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