Oil Dehydrator

Oil Dehydration

Industrial oil must not contain water. So it is an issue for oil systems. Nevertheless, water removal is possible and easy to do with oil dehydrator.

Though, only a few sources can give the real facts of unfortunate water contaminant in industrial oil. The oil dehydration is classical industrial equipment service, but we should also realize clearly why removing of water from oil system is so important.

Importance of Oil Dehydration

Degassing Equipment

Contaminated Transformer Oil Purification Methods

Transformer oil becomes contaminated and oxidized during use or long term storage. Small particles of transformer construction materials, as well as solved water and gas reduce the dielectric strength of the oil. Continued use of such product in the electrical equipment, failures are unavoidable. Therefore, many facilities protect their transformer using degassing equipment.

Until recently, oil was processed in stages by several different types of equipment to...

Bitumen Emulsion

Bitumen emulsion is a binding material, consisting of water and bitumen. Emulsion is a disperse system, with particles of bitumen dispersed in water. The main task is to keep  bitumen microparticles from coalescing,  which maintains physicochemical properties of the emulsion and its quality. This stability is achieved with special emulsifiers.

Bitumen emulsions are transportable, easily stored materials. They are kept in the storage warehouses in cylindrical containers...

Filter cart CMM-0,6

Mobile filter cart CMM-0.6 is designed for cleaning industrial oils with a maximum viscosity of up to 70 cts at a temperature of 50 °C.

During operation, transformer oil is oxidized and contaminated.  Transformer tank with a liquid dielectric accumulates moisture, impurities and gas. They significantly reduce the insulating properties of transformer oil. Oxidation and contamination are typical not only for transformer oil, but also turbine,...

Tap Changer

Oil Filled Tap Changer

Tap changer is a device that regulates voltage in transformers.  This device is usually useful when voltage in the system drops or surges. OLTC is an oil filled facility that requires special management and servicing.

Importance of Tap Changer

Certain conditions may cause problems in the system with sudden voltage changes. Voltage drops, for instance, can be caused by problems with the power grid or system repairs.

These problems are...


Transformer Insulating Oil

Transformer Insulating Oil

Electrical transformers need an adequate insulation. One of the most important components of insulation system is transformer insulating oil. It is a fluid or liquid substance that is common for transformer system and known as the most popular insulating material all over the world.

Transformer Insulation System

Each transformer has its own complex system of insulation. There always must be a combination of solid and fluid (or liquid) insulating components.

There...

TRANSFORMER OIL TREATMENT

Transformer oil is a liquid insulation and also substance, that transfers heat through system. So it is undoubtedly important to know basic rules and principles of transformer oil treatment. And, first of all, you must know main parameters of oil for transformers.

Types of Transformer oil

There are two commonly widespread types of insulating oils:

Mineral oils (based on naphtha products) Paraffinic oils

However there are plenty of the other possible transformer oil origins, the...

Restore Oil - Industrial oil restoration

Industrial oils usually get contaminated and oxidized. So it’s important to know, how you can restore oil. The mechanisms always need proper heat dissipation, insulation and also lubrication of bearings and gearboxes in turbines of power plants.

How to Restore Oil?

To restore oil and rejuvenate it to the original properties and parameters you need to work for special changes during operation. The changes depend on the type of oil and its...

Transformer maintenance

Normal operation of electrical devices depends on regular maintenance. Transformer maintenance is a prerequisite for its reliable operation.

How often is it necessary to perform transformer maintenance? It is not easy to give a clear answer to this question, since it depends on the technical condition of the equipment and no two units are the same. The standards set a maximum interval of four years.

Stages of transformer maintenance

Transformer maintenance usually begins...

Biodiesel Plant Production

Alternative fuels appeared due to several factors. First, the countries with limited mineral reserves were searching to reduce their fuel dependence from foreign suppliers. Secondly, alternative fuels were considered more environmentally friendly than traditional fuels. Therefore, a biodiesel production was reasonably thought as a way to solve both problems.

Biodiesel is a liquid fuel that is used in automobile engines. Studies have confirmed that, biodiesel spilled into...
