HIGH EFFICIENCY CONDENSING ECONOMIZERS
Stainless steel condensing secondary heat exchangers from AIC constitute an integral part of any efficiency improvement program.
Typically used with hot water boilers or configured with older type of heating boilers, condensing economizers improve the overall heat recovery system and boost boiler efficiencies.
AIC’s wide selection of design patterns and technologies exceeds even the most demanding customer requirements. E LINE
Secondary heat exchangers have been part of the AIC product eLINE features and benefits: portfolio for many years. Over this time, AIC has provided its customers with a great number of condensing products. • increased system efficiency by up to 20% • real energy and cost savings As your preferred OEM supplier of tailor-made products, AIC • converts standard boilers into condensing boilers has engineered and built a range of free-standing economizers, • unique tube design for optimal thermal performance for commercial and industrial applications. • easy installation, low maintenance
Implementation of efficiencies in thermal processes is a vital element in streamlining rising energy costs. Installation of Typical economizer applications include: condensing economizers can help companies improve overall heat recovery and steam system efficiency by up to 20% • district heating systems (in standard applications). • greenhouses • food processing plants eLINE • pulp and paper mills In the boiler room eLINE economizers transfer their waste • textile plants heat to either the feed water or combustion air pre-heaters, • dairy processing facilities essentially converting standard boilers into condensing boilers. • hospitals
Covering a wide range of boiler sizes (from 250 kW to up to 6 MW), the eLINE delivers real energy and cost savings for commercial and industrial installations.
