Micafluid Main

Micafluid is a leading developer and high service level provider of insulating oil and gas treatment plants.

The company specialises in the degassing, drying and filtration of oil used in power transformers and associated high-voltage (HV) equipment.

Micafluid’s range of products consists of oil treatment and regeneration plants, vacuum pump systems, and equipment for servicing and maintenance of sulfur hexafluoride (SF6) gas for switchgear, circuit-breakers, and HV transformers.

Cost-effective oil treatment plants for power transformers and HV equipment

The typically lengthy and expensive process of transformer oil replacement can be avoided through the use of Micafluid’s oil treatment plants, which save time and money, while guaranteeing the complete recovery of oil properties.

With Micafluid’s variable oil purification (VOP) plants, clients do not have to match their transformer to the size of their treatment plant. The company’s VOP product line ranges from a 300L/h throughput to units with a 30,000L/h oil treatment capacity.

With Micafluid’s treatment plants, oil flow is automatically adjustable, allowing for easier and more versatile operations.

The company’s plants use vacuum and Micropore filtration technology, while all units are PLC-controlled, integrating fully automatic functions that enable the treatment, purification and filtering of oil without de-energising the transformer.

Oil regeneration for power transformers and HV equipment

Micafluid’s compact and mobile oil regeneration systems improve the dielectric properties of aged oil, by using Fuller’s Earth technology and vacuum drying, and the units adsorb the carbonyl and hydroxyl components in the oil.

The systems consist of one or more adsorption columns, filter housing, and an optional inhibition set, which work together to remove the acidity and moisture from the oil. This process dramatically reduces long-term risks, while improving the oil’s dissipation factor, and refining its colour.

Micafluid’s regeneration units can be connected with separate drying and degassing oil treatment VOP plants.

Sulfur hexafluoride (SF6) gas treatment and recovery units

Micafluid has a more than 40 years’ experience in handling and treating gas-insulated power equipment.

SF6 is a heavy gas commonly used in metal-enclosed switchgears, HV circuit breakers and transformers, linear accelerators, capacitors, and gas-insulated power lines worldwide.

The company’s compact mobile units are fitted with all the required features to ensure safe, dependable and environmentally friendly treatment of SF6 gas.

Designed and built in Switzerland using state-of-the-art, heavy-duty European components, Micafluid’s gas treatment and recovery units (GTRU) recover, purify and refill SF6 gas, while offering a high degree of versatility through automated drive and control technology.

Micafluid’s GTRUs offer the optional ability of recovering and refilling one gas chamber, while simultaneously emptying another compartment as an additional benefit.

Standard units are available with internal tank sizes of 30L, 330L and 630L.

Accessories for measuring and monitoring SF6 gas quality

Micafluid supplies many accessories such as gas transfer hoses, valves, filters, and adapters. These can be used with the GTRU units, in addition to the required equipment for measurement and monitoring of SF6 gas quality such as digital pressure and vacuum gauges. They can also be used with regulators for the reduction of gas pressure.

The tools allow continued surveillance, which is essential for the longevity and sustained optimal operation of all gas-insulated electrical components.

Maintenance services for treatment plants

All units requiring maintenance are repaired and tested by Micafluid’s service specialists. A detailed service protocol will indicate the state of the unit on arrival, the work and testing needed, as well as guaranteed future performance after servicing.

Power plant maintenance and operation training

Personnel training and commissioning of the systems can be conducted at the client’s facilities or on-site.

Micafluid’s process engineers make use of the best practices to train operators regarding the use of the plant’s process control, operation and maintenance features.

Micafluid Virtual Assistance (MVA) Platform for online remote support

By subscribing to Micafluid’s Machine Virtual Assistance (MVA) Support Platform, users have instant remote access to their machine.

The company’s MVA system quickly enables organisations to remotely view and act on the oil treatment operation, reducing transport and operator costs.

A central database organises processes for future reference and makes traceability, comparison, and reporting easier and more efficient.

The MVA Support Platform also includes an option for a remote alarm system via SMS.
