3) FUME INCINERATOR SYSTEM
  • WE WOULD LIKE TO RECOMMEND TWO TYPES OF INCINERATE SYSTEMS AS UNDER. THE COMPOSITION OF INCINERATOR AND SYSTEM MAY CHANGE ACCORDING TO ENVIRONMENTAL STANDARD OF EACH COUNTRIES. BUT IF THE CUSTOMER WANT TO BUY THIS UNIT, THE BUYER SHOULD INFORM EXACT ENVIRONMENTAL STANDARD OF EACH COUNTRIES.
(1) CHAMMER BASE TYPE INCINERATOR SYSTEM
(2) ROTARY TYPE INCINERATOR SYSTEM

ABOVE COST OF THE FUME INCINERATOR MAY INCREASE ACCORDING TO ENVIRONMENTAL STANDARD OF EACH COUNTRIES.

GENERAL DESCRIPTION

  • THIS SPECIFICATION COVERS ONE COIL COLOR COATING LINE FOR PRODUCING VARIOUS COLOR COATED AL COILS & GI(GAVANIZED IRON) STEEL COIL PRODUCTS. THESE LINES ARE CONSISTED OF ENTRY SECTION, DEGREASING SECTION, COATING SECTION INCLUDING OVEN AND COOLING DEVICES, EXIT SECTION, ELECTRICAL EQUIPMENT AND INSTRUMENTATION AS SHOWN ON DRAWING NO. PMOHCCL-09-000-00.
  • WE HAVE PLENTIFUL TECHNICAL KNOWLEDGE AND EXPERIENCE REGARDING THE DESIGN, MANUFACTURE AND SUPERVISION OF INSTALLATION, COMMISSIONING, TEST RUNNING AND TRANING FOR COIL COLOR COATING LINE. WE ARE CONFIDENT OF SUPPLYING TO CUSTOMERS A COIL COLOR COATING LINE WHICH IS CAPABLE OF PRODUCING HIGH QUALITY PRODUCTS.
  • BASICALLY, THE LINE WILL BE PLANNED TO OPERATE BY SEMI-AUTOMATIC METHODS.
