Energy management system helps container manufacturer contain costs
In the highly competitive cardboard box business, where a penny apiece can mean the difference between getting and losing an order, St. Hart Container Corp., Placentia, CA, has gained a competitive edge by reducing its overhead with an energy management system (EMS). The Orange County firm, a division of Sunclipse, Inc., fabricates boxes to customer specifications from cardboard stock. The company is saving $2000 a month in electricity since it installed a Gereral Electric ECON-S programmable energy management system with telephone override capability late in 1984 to control lighting, air conditioning, and nine large blower and compressor motors. Installed by Hughes Electrical Management Systems (HEMS), City of Industry, CA, the $18,000 system paid for itself in only 9 mo. It initially controlled just 32 points and will be expanded to control the conveyors in the 60,000 sq ft plant. The primary savings, HEMS president Bob Hughes noted, accrue not from controlling lighting, but from automatically limiting the operating time of large blower motors that draw cardboard scrap from six fabrication areas on the shop floor up 2 ft dia funnels into a roof-mounted silo. The scrap is later compacted, baled, and sold for recycling.
