How can tank optimization benefit you? Ask the experts.

Rising oil and fuel costs, trends towards electrification, and overall concerns about sustainability across virtually every industry are driving an increased push for improved efficiency in the designs of hydraulic equipment.

One area where great opportunities for improvement lie is with the hydraulic tank. Due to inefficient designs, many machines operate with oversized hydraulic tanks containing more oil than needed.

Many benefits can be realized through tank optimization, including:

  • Increased energy efficiency
  • Overall machine weight savings
  • Steel and oil savings per machine
  • CO2 emission reduction
  • Tank downsizing
  • Additional machine space for other features

Read on to learn more about the benefits of optimizing your hydraulic reservoir, and how Schroeder Industries can help:

What Is Tank Optimization?

The goal of hydraulic tank optimization is to reduce the reservoir size and thus reduce its fluid volume. Two main factors determine how much a tank can be optimized:

  • Volume Utilization. In a suboptimal reservoir design, ‘dead zones’ can appear, where fluid stagnates and is not effectively utilized by the system. In a properly designed tank, every cubic inch of the hydraulic fluid should circulate within the reservoir. Dead zones can be detected by digital simulations, and are a strong indicator that tank optimization is needed.
  • Fluid Velocity. Fluid velocity impacts how well a tank can de-aerate, or release trapped air from within the fluid, and prevent new air from entering the fluid due to splashing. Increased air contamination causes a variety of issues within hydraulic systems, decreasing operating efficiency and component lifespan. Fluid velocity can be reduced through improved in-tank filtration and adjusting the structure of the hydraulic tank itself.

The Benefits of Hydraulic Tank Optimization

Here’s some of the ways optimizing a hydraulic tank design can benefit both OEMs and end users:

  • Cost Savings. Downsizing a reservoir with tank optimization means less steel and oil are needed upon initial construction, reducing up front manufacturing expenses for OEMs. Additional savings are passed on to end users, who will need less hydraulic oil to run the equipment over its lifetime.
  • Improved Energy Efficiency. A smaller reservoir with reduced fluid volume reduces the overall weight of the equipment, translating to improved energy efficiency. Lower fluid volume also reduces warmup time in cold start conditions. Any improvements in energy efficiency are especially important for electric-powered equipment, which relies on more limited battery power.
  • Increased Machine Space. A smaller hydraulic reservoir can allow overall downsizing of the equipment or make way for additional improvements to the design. Larger batteries or fuel tanks, cooling units and other beneficial modifications can be made when space is freed up within the machine.
  • Sustainability Benefits. Tank optimization reduces the carbon footprint of an operation in several ways:

    1. By downsizing a reservoir, less hydraulic oil must be produced and then disposed of, reducing the emissions from both the initial manufacturing of the oil and lowering the amount of waste oil per machine.

    2. The carbon footprint of initial construction is also mitigated by the reduction in materials needed to create the reservoir itself.

    3. Improvements in fuel efficiency for diesel and other fossil fuel-powered equipment reduces CO2 and other harmful emissions overall.

    4. Finally, the increase in energy efficiency and available machine space can open up avenues for electrifying equipment, or improving the performance of electric-powered machines, which are at the forefront of sustainable equipment.

The benefits of optimizing your tanks are clear, and the filtration experts at Schroeder Industries can help you get the most out of your reservoir.

An OEM customer producing stump grinding machines for the forestry industry came to Schroeder Industries searching for updated filtration solutions.

An engineering analysis of their fabricated tanks found that not only were they heavy and prone to weld cracks: The volume utilization was subpar.

Further testing concluded that the existing Schroeder TNK12 would provide equivalent deaeration performance to the customer’s current tanks with a 40% reduction in tank volume.

This resulted in substantial savings on both oil and tank production cost in their stump grinder manufacturing:

Oil reduced per unit: 8 gallons
Oil Reduced annually: 4,000 gallons
Cost savings: $28,000 USD
Labor cost per TNK: $30 USD
TNKs used annually: 500
Labor cost savings: $15,000 USD
