Fluid Conditioning Unit for Accelerated Oil Aging
The innovative tool to accelerate lubricant aging and investigate their change of properties.
Fluid conditioning unit for accelerated oil aging.
FLUCOIL is designed to study the changes of lubricant properties during their lifetime.
This innovative test rig also allows comparing lubricant formulations while speeding-up the aging process.
The equipment can be programmed to simulate lubricant conditions in real mechanical systems such as internal combustion engines, e-powertrains, gearboxes, industrial transmissions, compressors, and other mechanical systems.
FLUCOIL offers the following functionalities:
Selectable operating temperature between 0°C and 160°C (up to 250°C as an option)
Forced oxidation process by mixing air to oil at selectable and controlled rates. Injection of other oxyding gases such as NOx is also possible
Forced mechanical shear using gear and / or piston pumps that are operated at programmable speeds and loads to generate high pressure in the oil circuit, and allow the injected gas to be dissolved
Possibility to inject continuously fuel or water-based contaminants (coolant) to simulate a dilution process
Possibility to inject soot (black carbon) and / or micrometric metal debris
A range of smart probes is available to monitor critical parameters such as:
Viscosity
Dielectric constant
Resistivity
TAN / TBN
Aeration properties (measurement of dissolved and non-dissolved fractions)
Concentration in wear debris
Thermal conductivity
Electrical conductivity
Electrical permittivity
Lubricant impedance
Oil samples can also be taken periodically to measure additional oil properties in a laboratory, or to perform tribology tests at different periods during and after the aging process.
Time and Energy savings
Compared to real mechanical systems, FLUCOIL reduces significantly test durations and allows saving significant amounts of energy.
The equipment only requires electricity supply.
Energy consumption in the range of 1 kWh per litre of oil and per hour of test.
As test durations of are typically reduced to 50 hours, this means that less than 250 kWh energy consumption is required to age 5L of lubricant.
Automation
FLUCOIL is fully PLC controlled.
Equipment is operated using a local handheld HMI where operating conditions are easily programmed:
– Test duration
– Number of cycles
– Oil temperature range
– Air/Gas injection rate
– Fuel injection rate
Aeration devices
Air-X
Air-X device is designed for on-line monitoring of oil aeration in a running mechanical system. The operating principle is based on an accurate density measurement using X-ray transmission. An oil sample coming from the mechanical system is circulated continuously into a compact measuring chamber where the density measurement is performed.
Applicable on all fluids
Real-time aeration monitoring
Accurancy 0,5% at 10 sec and 0,2% at 100 sec
T° range: -10°C to 160°C
Air-MIX
Air-Mix allows to simulate real oil aeration conditions for test and development of undergoing mechanical systems and/or to compare lubricants. This oil conditioner is used to study the impact of aeration on ongoing mechanical systems, Study of hydraulic tanks and filters deaeration capacities, …
Fine aeration range : 0 to 25% for various lubricant types
Coarse aeration range : 0 to 75% for simulation of scavenge systems
