February 5, 2016News

Guests from Switzerland visited GlobeCore German office in Oldenburg at the beginning of February

Director and chief engineer of Swiss company wanted to learn about GlobeCore equipment for cleaning mineral oils and other petroleum products. Guests were shown UVP, CMM-R and CMM installations. For their better understanding of the principle of regeneration the samples of contaminated oil were treated in the laboratory version UVR installation.

Great interest of Swiss guests caused CMM-R installation in reactivating sorbent technology. This equipment uses fuller’s earth absorption for oil degradation products. GlobeCore has a unique method which allows to recover sorbent properties directly in the oil recovery equipment and reuse it for processing mineral oils. The regeneration process is not interrupted for replacement of the sorbent. Reactivation is undoubtedly beneficial to the environment. Fuller’s earth can be recovered up to 300 times, which is equivalent to 2-3 years of work regenerative CMM-R.

On the whole, the visitors from Switzerland were pleased with their trip, and expressed a desire to visit the GlobeCore office and production facilities again to discuss the future cooperation.

GlobeCore Presents Its Equipment in Kyrgyzstan

January 12, 2016News

7th to 11th December, 2015 GlobeCore representatives visited Kyrgyzstan (the cities of Bishkek and Osh).

The main purpose of the visit – was presentation of equipment produced by the Company, as well as establishing new and strengthening existing business contacts.

During the events representatives of the electric power industry of Kyrgyzstan had an opportunity to familiarize themselves with regeneration units for transformer oil, such as: CMM-R and UVR, CMM degassing unit, Mojave Heat Hot Air drying unit and others. The second part of the presentations included regeneration of provided samples of transformer oil on the laboratory model of the UVR unit.

Particular attention was paid to the technology of regenerating insulating oil as one of the most promising ways to improve reliability and extend service life of power transformers. As a solution to this problem, GlobeCore offers a unique technology using a special sorbent (Fuller’s earth). What’s important is that the sorbent can restore its properties (reactivate) directly in the regeneration equipment. Thus, you don’t need to pause for restocking and replacement of Fuller’s earth, thereby reducing standby time.

The CMM-R unit can process transformer oil directly in the transformer. Herewith the transformer can be both : connected or disconnected to electricity.

GlobeCore oil regeneration technologies achieve following targets:

protect transformer’s hard insulation;
restore operational properties of transformer oil to its original conditions;
reduce operating costs (a single operator is enough to control the unit);
increase reliability and extend service life of power transformers;
reduce expenses for disposal of waste and purchase of new oil; and
increase the dielectric strength of oil.

Table 1 shows results of physico-chemical analysis of transformer oil processed on regeneration unit (a laboratory UVR model).

Transformer Oil Purification Unit Was Successfully Commissioned On the Offshore Drilling Platform

September 22, 2015News

On July 5, 2015 the GlobeCore Clean Marine Unit (capacity 4m3/h) was commissioned on the offshore drilling platform, in 250 km from the Nigeria seacoast.

The electric equipment at the offshore deep-water drilling platforms are operated under heavy conditions, being exposed to waves, the wind and salt water.

A power transformer is an integral part of the electric power system of the drilling platform which determines a smooth and uninterrupted operation of drilling rigs and creates favourable working conditions to the staff.

Transformer oil is an important element of the transformer insulating system that insulates current-conducting parts of the transformer from non-conducting ones. Unfortunately, physical and chemical characteristics of oil have a potential to degrade during operation that affects badly the smooth operation of the converting equipment.

Clean Marine unit is used to vacuumize and maintain offshore power transformers as well as to remove water, gasses and mechanical impurities from transformer oil. In addition, GlobeCore‘s Clean marine unit fully complies with the requirements for equipment, operated in the marine environment.

Clean Marine Units are compact in size, protected from moisture ingress and explosion proof.

This unit may be operated in the following modes:

(1) transformer’s heating up;

(2) oil’s degassing;

(3) transformer’s vacuumizing.

GlobeCore‘s Clean Marine equipment restores transformer oils to its new-like condition, thereby extending their service life. As a result it increases the electric reliability of the offshore drilling platforms, saves money on new oil purchase and waste oil disposal of.

The following are selected photos from the commissioning:

The Visit of Turkish Delegation

July 20, 2015News

On April, 27 GlobeCore received the guests from Turkey.

The representatives of Andritz Hydro LTD. STI and the representatives of General Directorate of State Hydraulic Works, Dams and HEPP Department came to the GlobeCore facilities to test the CMM-8.0 unit.

It should be noted that General Directorate of State Hydraulic Works is the main executive body of Turkey, responsible for development, planning, regulation and servicing of natural resources. The main priority areas of activity include project management, construction and servicing of hydroelectric power stations.

Hydro turbines are considered to be the main part of the hydroelectric stations that bring into action generators that produce electric power. Turbine oil is used to lubricate bearings and reduction gears of turbines.

During servicing, oil is affected by gasses, gaseous products and water that leads to oil’s aging. As a result, oil loses its anticorrosion, antioxidant, antiwear and anti-foam properties. It is therefore, old turbine oil should be replaced or restored to its original condition. The second variant is cheaper since there are no expenditures on new oil purchase and disposing of waste oil.

The GlobeCore CMM-8.0 is designed for degassing, dehydration and filtration of turbine oils that allows for its service life extension and costs reduction.

The Turkish delegation was present during the equipment testing. The obtained results have shown the readiness of the CMM-8.0 unit to solve the tasks.

The employee of Andritz Hydro LTD. STI Irsad Akaydin has shared with us his impressions about the visit: ”We have arrived at the GlobeCore production facilities to test the equipment. Everything was great. I haven’t heard about GlobeCore technology before, that’s why we gained great experience visiting this company. We are also very happy to have visited production shops and got acquainted with the peculiarities of the works carried out”.
