KEY BENEFITS
• Simple & rigid construction (flexible): use of standard units, modular systems
• Post-combustion chamber: elimination of odour and organic matters
• Generation of energy: electric power production, external use of heat and steam (marketable)
• Low space requirement: 2 stage incineration, integrated in 1 housing, compact construction (2-3 acres) plus handling, storage, etc.
• 100% environmental friendly: complete air pollution control
• Easy operation: automatic function control, large openings for firing and ash discharge, optionally automatic charging and ash discharging systems
• Low operation & maintenance costs: all important components are clearly arranged and easy to access
• Made in Germany quality: extremely long-life cycle
• Approved and patented products: complies with various standards (DIN/EN, VDE, TUV Certified ISO 9001 : 2000)
