HYDAC supports steel industry to be the best it can be

HYDAC is integrally involved in the steel industry due to its wide range of relevant products combined with expertise in product and system development, manufacturing, sales and service. 

In partnership with customers HYDAC has proven its ability time and again to overcome diverse and challenging problems besetting the industry. 

Service and support encompass monitoring oil cleanliness and oil ageing in hydraulic and lubrication oils, measuring technology and electronics, cooling, filtration, dewatering and oil maintenance units, and hydraulic systems and components.

Analysis and diagnostics

Seventy to eighty percent of all breakdowns in hydraulic and lubrication systems are due to contamination of fluids and components used. In this regard HYDAC offers a comprehensive range of easy-to-use measurement and analysis equipment to monitor operating media and component cleanliness as well as fluid laboratory vehicles.

Commissioning, optimisation, engineering

The package HYDAC provides is a comprehensive fluid engineering concept from cleaning and maintenance packages to system optimisation. 

“Our concern is to improve the operational availability of machines and hydraulic systems,” a HYDAC spokesperson comments.

“Fluid engineering is the total package of technical and commercial services for the benefit of the customer.”

For every task the right solution

Condition monitoring of oil cleanliness and oil ageing in hydraulic and lubrication oils comprises the following:

  • Measuring technology and electronics
  • Cooling and filter systems
  • Extending service life and ensuring operational safety through use of high-quality filtration
  • Dewatering and oil service units
  • Hydraulic systems and components

Condition monitoring with sensor technology

Condition monitoring with sensor technology encompasses the following: 

  • Sensors for condition monitoring in hydraulic and lubrication oils
  • Observation and planned maintenance work according to changes in initial state in terms of oil cleanliness, water content, and viscosity.
  • Avoidance of critical system conditions such as tank overflow and unplanned system stoppages 

Water in oil

The Aqua Sensor AS 2000, Aqua Sensor AS 1000, and ASFW Sensor (free water) are used for water in oil applications.

Solid particles in oil 

Contamination Sensor CS 1000, Contamination Sensor CS 2000, and Contamination Sensor FCU 2000 are used for solid particles in oil applications.

Water/solid particles

Fluid Monitoring Module (FMM) is used for water/soil particle applications.

Oil ageing

The HYDAC Lab Ageing Sensor is used for oil ageing applications. 

Oil level

Electronic Fluid Level Sensor ENS 3000 is used for oil level applications.

Measuring technology and electronics 

HYDAC offers a comprehensive range of sensors for measuring pressure, temperature, flow rate, filter contamination, and fluid level, with Pressure Transmitter HDA 3800 being a good example within this range.


HYDAC has many years’ experience in transmission oil and hydraulic oil filtration. The fluid power company develops optimised systems for main filters, offline filters, and breather filters.

Examples are Changeover Filter RFLD, Pressure Filter DF, Betamicron, MegaRheo elements, dewatering unit FAM,

OLF offline filtration with Contamination Sensor CS 2000, and bypass heating filter cooling circuit.

HYDAC filters with high quality

Media temperature in systems

Media temperature in systems equipment includes an oil/air heat exchanger, plate heat exchanger, and gasketed plate heat exchanger.

Hydraulic components and systems

Systems advice and sizing for design, manufacturing, commissioning and after sales service are par for the course such as nitrogen charging units for charging or topping up accumulator systems, hydraulic accumulators for safety functioning and for managing energy peaks, valves and blocks for fluid systems, and blast furnace gas expansion turbine of tank volume (oil tank volume of 9,500L, power 500kW, flow rate 760L/min).

Rolling emulsion

Key technical data

Rolling emulsion key technical data are as follows: system supply flow rate of 1000 to 2000L/min (with frequency control), and supply pressure approximately six bar on the rolling stand.

Emulsion processing

Emulsion processing data is as follows: black-flushing filter RF 3-2.5 in the bypass with > 2,200L/min, 4.5 bar, 50µm slotted strainer candles, and back-flushing at a maximum of 0.15 bar.

Process filtration

HYDAC AutoFilt RF3 automatic back-flushing filter in process filtration is used for descaling sheet metals and slabs, cooling lubricant systems, as a protective filter before pumps, feed watering filtration, and in belt systems.

Special applications

The following applications usually fall under special applications, ie special cylinders (benders), reservoir levels (electrical furnace), pump stations (ribbon lap plant), valve units (slab strip casting plant), and circulating paths (continuous casting plant).


HYDAC’s accessories for the steel industry include ball and fluid level gauges; pipe fasteners, hose and cable fasteners, component fasteners; and bell housings and couplings.


To make matters easier, commissioning takes place on-site at the customer’s premises.

After-sales service

And it goes without saying that HYDAC is ready to help with any matter big or small post-purchase or service.

HYDAC steel industry

Industry outlook glimpse

Shipbuilding and repair services in Australia

The shipbuilding and repair services industry is expected to be minimally affected by the COVID-19 pandemic, according to IbisWorld research.

The industry and market research database firm says industry revenue is less affected by economic influences as revenue is largely made up of defence contracts funded by the Australian Government.

Revenue for this industry, according to the research, is forecast to grow at an annualised 4.2 percent over the five years through 2026-27, to total $4.9 billion.

Nickel ore mining in Australia

Industry firms mine nickel-bearing ores, according to IbisWorld Research. These firms may also carry out basic nickel ore beneficiation processes to produce nickel ore concentrate.

Nickel prices are forecast to continue rising over the five years through 2025-26, says the industry and market research database firm, with industry revenue expected to rise strongly over the period. This is also projected to lead to increases in enterprise and employment numbers.

Higher prices, says the research, are anticipated to encourage new enterprises to enter the industry and limit the number of exits.

Structural steel fabricating in Australia

Industry firms manufacture structural steel components that are used in buildings and other structures, according to IbisWorld research.

The industry's performance is expected to be influenced by decline in demand from the construction division, which is expected to be adversely affected by the economic instability stemming from the pandemic, says the industry and market research database firm. 

Therefore, says the research, local investors are likely to have a diminished capacity to fund new construction projects while foreign investment in the local property market is projected to be disrupted by instability in global financial markets. Industry revenue is forecast to contract by 10.2 percent in 2020-21, falling to $6.3 billion.
