ESL stands out for its paralleling, synchronizing and load sharing solutions involving sets of any make, model, manufacturer, mix of fuel and MAINS. It performs these jobs with its own resources, without taking recourse to outside vendors. It has a long list of successful installation of synchronization solutions which are paying dividends to the customers for many years. Some of these notable installations are:
1. ATS Synthetic Private Limited
ATS Synthetic is one of the largest synthetic plants in the country. It has continued to show its confidence in ESL services and products.
ESL has installed yet two more sets of 1540 KW @ 11,000 Volts Cummins powered lean burn gas generators at their plant. These Gensets are continuously subject to very high torque loads. ESL had previously installed three Cummins sets of similar rating which have exceeded 60,000 hours of operation and their performance is a clear manifestation of reliability, durability and lowest total cost of operation. The power plant has a total of five Cummins gas generators and three 1800 kW Aksa diesel generators @ 11 kV commissioned, paralleled and maintained by ESL which speaks volumes of the performance of products and service solutions provided by ESL.
2. Coca Cola Beverages
SL supplied 2 x 2250 kVA Aksa gensets with Cummins QSK60G4 engines and New Age Stamford Alternators to Coco Cola Beverages, Lahore. In addition, 2 x 1.6 MW Aksa Diesel generators were also supplied to the same facility. The scope of work included installation, testing and commissioning of gensets and synchronizing the new gensets with existing 2 x 1250 kVA Cummins and 1 x 500 kVA Caterpillar gensets. The whole arrangement has a bumpless load transfer facility from Mains (WAPDA) to genset and vice versa involving four Transformers.
ESL also supplied 2 x 515 kVA Aksa gensets with Cummins QSX15G6 engines and New Age Stamford Alternators to Coca Cola Export, Lahore.
The scope of work included installation, testing, commissioning and synchronizing. The whole arrangement again has a bumpless load transfer facility from Mains (WAPDA) to genset and vice versa using state of the art Woodward’s controllers.
3. Shaukat Khanum Cancer Hospital & Research Centre
ESL supplied, installed, commissioned and synchronized 2 x 550 kVA Aksa gensets in Shaukat Khanam Research Centre, Karachi.
ESL also installed 1 x 1370 kW Cummins gas and 1 x 1600 kW Caterpillar gas gensets in Shaukat Khanum Hospital, Lahore. In addition to that ESL supplied, installed and commissioned 1 x 1410 kVA Aksa Diesel set to the Hospital.
ESL has also been successfully shouldering the responsibility of providing synchronizing systems for all 3 x 1410 KVA diesel, 1 x 1370 KW Cummins gas and 1 x 1600 KW Catterpillar genset.
Shaukat Khanum Cancer Hospital continued to show its confidence in ESL products and services for upgradation of LT distributions and Medium voltage substation. ESL completed this project in record time of six weeks without any shutdown to the main hospital building.
4. Shahtaj Textile Limited
Shahtaj Textile Limited (a Shahnawaz Group Company) opted for Cummins lean burn gas generators from ESL mainly on account of their ability to start large compressor motors.
The customer carried out an in-depth analysis of all contemporary products prior to a purchase decision and selected ESL Cummins lean burn gas solutions because of their capacity to handle the large block loads (almost as efficiently and smoothly as diesel generators do).
Both ESL and Cummins lived up to their reputation. The site is an ideal demonstration of Cummins single step load acceptance (torque load) capability.
ESL also considers Shahtaj as a flagship project for the entire textile industry. These generators are a telltale demonstration of Cummins Energy Solutions in terms of no or very low deration, operation at low gas pressures, ability to handle compressor motors of 600 kW, steam generation from exhaust heat and low total cost of ownership.
