Any oil used in manufacturing or in any other industry becomes contaminated with time. This reflects not only on the oil’s color, but also on its physical and chemical properties. Naturally, light oil looks better. The main task of purification is to remove impurities, such as resins, certain hydrocarbons, solid particles and water from theRead More
DRYING OF TRANSFORMER INSULATION: WHEN IS IT NEEDED? Transformer insulation needs drying to fully comply to existing standards and requirements. The cases in which the drying of transformer is necessary are as follows: traces of water were found on the active part or in the tank; storage of a transformer without oil exceeded one year;Read More
Transformer oil is not only a lubricant that protects the active part of high voltage equipment from overheating, it is also an arc suppression medium and protects transformer from penetrating moisture. Therefore, the life of transformer equipment directly depends on the quality of a dielectric used. To avoid undesirable consequences of a contaminated dielectric, itRead More

Exhibition Feria Internacional del Sector Eléctrico was founded in 2006 and today is one of the largest events in Latin America dedicated to the electrical industry. The seventh exhibition gatheredRead More
Power transformers are the basis of the modern electric power industry. Their reliable operation guarantees the delivery of electricity to large industrial facilities and ordinary consumers. In this article we will consider the oil servicing – as an important component of the transformer insulation maintenance. We shall begin with functions. Oil in transformer isolates individualRead More
Industrial OIL CLEANING : BASIC METHODS Petroleum base oils are indispensable in many industries, performing heat-removing, lubricating, protective functions etc. Oils are constantly exposed to many negative factors, which include friction, exposure to high temperatures, oxygen, pollution by mechanical particles. As a result, oil begins to lose its properties and can not continue to performRead More
In the beginning of December, our representative visited the island nation of the Philippines to present GlobeCore oil purification and regeneration equipment to the local oil refining industry. The presentations were organized on 4-7 December in five cities: Bulacan, Marilao, Valenzuela, Cabuyao and Consolacion. Operation of the regeneration equipment was illustrated by a UVR technologyRead More
21 November, Doha, Qatar: GlobeCore presents mineral oil purification and regeneration units. The event was attended by representatives of KAHRAMAA (Qatar General Electricity & Water Corporation), the main power and water supplier in the country. Also were present the representatives of Al Dana Switchgear company (A Subsidiary of AALCO Group) which were the co-organizers ofRead More
Dear friends! We are happy to announce that a new service center commenced operations in Costa-Rica in November 2017. This service center will assist our clients throughout the Latin America. A stock of spare parts will be made available to the clients. It is also possible to visit the new service center to purify andRead More
Cooling classes of liquid-immersed transformers are covered by IEEE C57.12.00 A short explanation of each class follows. Liquid-Immersed Transformers, Air-Cooled There are three classes in this category. 1. Class OA: Oil-immersed, self-cooled. Transformer windings and core are immersed in some type of oil and are self-cooled by natural circulation of air around the outside enclosure.Read More
An oil purifier is a device designed to remove harmful impurities (solid particles, water and gases) from oil. Oil purifier: what was it like before? At first, large sedimentation tanks were used as oil purifiers. Contaminated oil was kept in the tanks for a period of time. Large impurities in the oil gradually settled onRead More
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 weRead More
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 transformerRead More
September 17, GlobeCore CMM-2.2 was commissioned in Foligno (Umbria Region), Italy. This equipment is designed for silicone oil purification. This type of oil is a modern lubricant, which has a large number of silicon atoms in its composition. Hence the name of the product (silicon in Latin – silicium). Silicone oil is widely used inRead More
Oil processing is a critical practice for extending the lifespan of oils and the equipment that depends on them. Regular oil processing not only leads to significant cost savings by reducing the need to purchase new oil but also enhances machinery performance and supports environmental sustainability by minimizing waste. This article explores various techniques ofRead More
Power transformers are an essential part of the modern electric power industry. Their reliability ensures power supply to large industrial facilities and residential consumers. In this article we will learn about transformer oil, which is an important part of transformer insulation system, and oil maintenance. Let’s start with oil functions. Oil in a transformer isolatesRead More
Bitumen modification is a process most often used in the production of high quality materials for road construction and repair of highways, as well as roofing. The product certainly deserves consideration. What is bitumen modification? Scope of use. Bitumen is a black substance insoluble in water that contains high molecular weight hydrocarbons and their derivatives.Read More
Portable oil 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. OxidationRead More
