ANCA
achieves 10% increase in energy efficiency through use of high
efficiency motors and improved controls
One of ANCA Metal Treatments' most significant environmental aspects is energy consumption. However, over the past 12 months the company has become 10% more efficient in its use of electricity, both as a means of working towards ISO14001 certification and meeting the terms of its Climate Change Levy agreement. Under this agreement, negotiated through the Surface Engineering Association, targets are set for greater energy efficiency, in return for a discount in the Climate Change Levy (CCL) paid by the company. Any organisation operating a part A1 or A2 process, as defined by Schedule 1 to the Pollution Prevention and Control (England and Wales) Regulations 2000, is eligible to negotiate a CCL agreement with the government, either through a relevant trade association or independently. For more information see www.defra.gov.uk/environment/ccl/index.htm
For ANCA the biggest users of electricity on site are motors, and so a two-pronged strategy was adopted to both increase the efficiency of individual units and reduce the time that they run. Some of the measures adopted include:
replacement of the existing 15kW fan motors within the process oven with Siemens high efficiency motors, which use approximately 34% less energy to achieve an equivalent output; replacement of the existing air compressor with a smaller, high efficiency unit. Despite its reduced rating (18kW vs 56 kW) it is still able to meet demand, by running at higher pressure and by the use of control values on the process tanks;• installing timers on the effluent plant control circuit so that mixers are used only when required. This has reduced running times by 75%;
introducing timers on the ultrafiltrate rinse tank recirculation motors. This has reduced running time from continuous to 5 minutes per 2 hours, greatly reducing energy use but without product quality being affected;
installation of a float switch on the circulation pump of the water demineralisation plant, which turns off the motor once the holding tank is full. Despite a slight increase in the conductivity of the water as a result of this measure, the water is still to specification.
As a result of these measures, ANCA Metal Treatments has already achieved its targets set under the terms of the CCL agreement, and has plans to implement further energy efficiency measures in the near future.
