“SR LTD” activities include supply of electrical equipment, engineering, setting-up and maintenance of industrial electrical equipment, staff structure consists of certified specialists in the field of industry automation and electric drive, with extensive knowledge and practical experience, capable of executing a complete range of works, from project creation to commissioning of automatic control system of any complexity.
Our employees have been using SIEMENS equipment since 1985. In particular, took part in setting-up and putting into operation of such facilities as “HEID” and "EMAG" pipe threader and coupling sleeve machines, “LAEIS” presses and “MANNESMANN DEMAG” steel degassing complex, circular and section-type gas heating furnaces, railway-wheel-and-tire mills etc. at INTERPIPE NTRP.
Automatic control systems
Automatic control systems created by our specialists, have intellectual capacity, which enable analyzing the process and finding optimal method of facility management.
Control systems of above mentioned facilities based on SIEMENS equipment (SIMATIC-S5, S7, SIMOREG, SIMOVERT, SINUMERIK).
Company employees underwent training at certified SIEMENS study courses in Moscow, Kharkov and Donetsk.
Jointly with heavy presses plant, we have developed an automatic control system for firebrick press. This press is analogue of “LAEIS” presses made to the order of Zaporozhye firebrick plant, and a unique unmatched control system for 3D parts press by extra-high pressure method.
Forging plants are one of the main areas of activity of our company. ACS for forging presses were developed and put into operation with thrust 1250 ton-force “Azovstal” OJSC, Mariupol, 3450 ton-force. For Yurga iron and steel works, Yurga, Russia, 3150 ton-force for Haridwar heavy machinery plant, Haridwar, India.
Axis-controlled machines reengineering is one of areas of activity of our company. Our specialists can match individual CNC configuration in each specific case to find good value for money.
Considerable energy saving can be achieved, using frequency converters on industrial plant pumps and fans. Also application of frequency regulation prolongs service life of mechanisms. Payback period makes from 0.5 to 1.5 years.
We have installed a number of frequency converters at Dnepropetrovsk Vtormet OJSC on pump station of big и and small heat supply circle and 40 drives at INTERPIPE NTRP on exhausters, heating furnaces fans, process pumping stations. After installation we succeeded to reduce power consumption 1.4-1.8 times.
We also have an opportunity to supply high voltage frequency converters of different purpose.
Our specialists can develop a correlation project of frequency converter for each specific case, execute erection and setup works, and provide equipment technical support at the facility.
Since 1994 the company generally looks out for SIEMENS equipment. During this period we have carried out the delivery of SIMATIC-S5, S7 components, DC and AC electric drives, CNC, setup electrical equipment, programming tools. Our key partners are SIEMENS Automation Department offices in Kiev and “IngenieurBuroUweTetzner”, Aahen, GERMANY.
