Costs reduced for exporters of top brand apparel
07 March 2017
Since first opening in 2007, Sri Lanka’s MAS Fabric Park has been firmly committed to maximising an environmentally friendly culture and reducing any impact operations have on its surroundings.
So when the MAS Fabric Park wanted to reduce the current energy consumption at its Waste Water Treatment Plant, it looked no further than Invertek’s variable frequency drive technology which has already seen savings made of between 28,000-30,000+kWh of energy every month.
Harsha Deraniyagala, Deputy General Manager for Hydro & Environment at the Park, said the company is delighted with the results as the Invertek installation is already returning an OPEX saving of about Rs. 4.5 Million/annum (£48,000 approx.) and the costs entailed will be paid back in just a ten-month period.
Before the CETP-VFD project was implemented, about 3,000kWh/day was being consumed and this figure had now come down to less than 2,000KWh/day. This has had no effect on the dissolved oxygen levels in the deep aeration tanks which are still well within stipulated limits.
Anushka Chandrasoma, Application Engineer at Hayleys Industrial Solutions (Pvt) Ltd, Invertek’s sales partner in Sri Lanka, said the Park had four 22kW rated re-circulation pumps fixed inside the deep aeration tanks with motors running for a minimum of 22 hours per day and the customer wanted to save at least 25 percent of the present consumption by fitting VFDs to them.
Invertek were also asked to fit VFDs for 75kW rated aeration blower and one 11kw high lift pump, which again were running for up to 20 hours per day.
This installation highlights that Invertek’s VFDs are one of the best options for companies wanting to make immediate and significant savings in their energy usage, which they will continue to benefit from for many years.
Invertek are planning to showcase the success of this installation to other companies working in the HVAC sector.
Harsha added that the company was delighted with the efficiency of the whole operation and the fact the work was completed to deadline without any need for Park customers to suffer any shutdowns.
This is particularly important as the Sri Lankan textile and apparel industry is a pivotal driver in the country’s employment levels and utilises 15 percent of work labour available as well as servicing some of the biggest apparel brands in the world such as Nike, Victoria's Secret, Ann Taylor and Marks and Spencer.
Park are now considering a similar installation at its sister plant where there is also room for energy savings as high capacity motors are currently being used.
Dylan Davies, Invertek’s Product Manager, said this installation used the Optidrive Eco variable frequency drives which have been designed to provide maximum operating efficiency while minimising environmental impact.
Accurate speed control and an energy optimisation function made this the perfect choice for the Park which is already reaping the benefits from lower energy consumption meaning the Park will soon see payback for the cost of the drives and the installation.
