ORGANIZATION CHART FOR PRODUCTION TEAM Manager of Production Team Production Control, Procurement, Materials Control, Deployment Quality Assurance Process Engineering Production PRODUCTION SITE Boiler production line: 1 (Daily production capacity 400 sets) Pump production line: 1 (Daily production capacity 600 units) Location: Gwangju, Korea 4
TECHNICAL FEATURES 1. Adaptable ignition system (world patented technology) Ignite burner by control of MICOM in accordance with variance of combustion ranges, i.e., gas pressure, chimney, wind and voltage Utmost convenience due to no adjustment 2. Automatic combustion control (world patented technology) Infrared electronic sensor automatically detects condition of flame and supplies optimum amount of air Save energy 3. Sufficient hot water Sufficient hot water supply when use hot water Hot water comes out quickly when open the water faucet Still enough hot water when heavy use or low water pressure 5
TECHNICAL FEATURES 4. Pump Canned type pump Reduced vibration noise Enhanced reliability The structure of pump 6
TECHNICAL FEATURES 5. Remote controlling Boiler is operated by room controller 6. Self error-detection Errors are indicated in room controller and automatically stop the machine 7. Modulation MICOM and modulation gas valve control combustion in linear temperature condition with least variance 8. Prevention the pipe from freezing to burst If the water inside of the pipe is getting cold, the pump automatically operates or the boiler automatically start combustion to prevent from freezing to burst 9. Good serviceability Easy-to-assemble and -disassemble (need only one screw-driver) 7
