CF-SL Metallization Drying and Firing Furnaces Brochure

u CF-SL Metallization Drying and Firing Furnaces The world’s best selling metallization furnaceFor highly efficient solar cells at the lowest possible cost, more solar manufacturers choose Despatch Firing Furnaces than any other brand. The drying and firing system is easily integrated with every major metallization printer line and provides advanced technology to accomodate next generation pastes. The furnace is now available with SolectFireTM Technology. This critical advancement opens the process window and gives operators independant open and closed loop control of the top and bottom of each firing zone. This innovative decoupling technology provides greater thermal control and sets the stage for next generation pastes.Despatch CF-Series metallization furnaces are designed for high throughput, ease of maintenance, and consistent process repeatability ensuring consistently high yields and superior product quality. Patented push-button chamber access and optional VOC Thermal Oxidizers make maintenance a snap. These innovations maximize performance and up time and result in lowest cost of ownership while producing the highest efficiency cells.I N S P I R E D I N N O V AT I O NPatented technologyM i n n e a p o l i s • s h a n g h a i • B e r l i n • s i n g a p o r e • h s i n c h uFeaTures aT a glanceu Rapid thermal ramping (up to 200°C/sec)u Enhanced thermal cooling (up to 200°C/sec)u Up to 300 ipm belt speedu Uniform, stable and repeatable cavity temperature (+/- 2°C)u Mesh belt with stand-offsu Soft start with reduced connected loadu Enhanced software recipe managementu Advanced graphical user interfaceu Master production control interfaceu Data loggingu Redundant over-temperature shutdownu Safe, simple chamber accessibilityu Eye-level electronics for easy maintainanceu Failed element monitoru Uninterruptible power supplyu Integration to wafer automation equipment New advanced thermal control TMCF-SL FiringCDF-SL Drying/FiringproDucT conFiguraTionOverall length 736 cm (290 in) 1147 cm (451.5 in)Overall width 121 cm (47.5 in) 121 cm (47.5 in)Overall height 164 cm (64.5 in) 164 cm (64.5 in)Standard entrance/exit table 93.5 cm (36.8 in) 93.5 cm (36.8 in)Open inspection area NA 46 cm (18 in)Conveyor type Lightweight balance spiral weave, Nichrome V material, friction drive with stand-offsConveyor height above floor 91.5-99 cm (36-39 in) 91.5-99 cm (36-39 in)Conveyor width (custom configurations up to 24in/61cm wide available) 25.4 cm (10 in) 25.4 cm (10 in)Net weight 2,270 kg (5,000 lbs) 3,400 kg 7,500 lbs)elecTrical reQuireMenTsVoltage 380–480V/3 phase/50–60 HzConnected load 52 Amps 70 AmpsTypical operating load 36 Amps 49 AmpsWaTer reQuireMenTsTypical flow 11 lpm 11 lpmPressure (maximum) 4 Bar (60 psi) 4 Bar (60 psi)pH level 7.2–7.6 7.2–7.6Recommended inlet temperature 16–18°C (59-64°F) 16–18°C (59-64°F)eXhausTProcess exhaust venturi assist *hood required, no direct connection2 sets 4 setsCabinet exhaust 850 M³/hr (500 scfm) 1700 M³/hr (1,000 scfm)process aTMosphereClean dry air (CDA) (Typical) 22.7 M³/hr (13 scfm) 50.5 M³/hr (30 scfm)process capaBiliTiesMaximum temperature (Drying/firing) 1000°C 400°C/1,000°CConveyor speed range 66–762cm/min (26–300 ipm) Conveyor speed accuracy ± 0.5% ± 0.5%Throughput (6x6in/156x156mm wafers * up to 2,500 wafers/hour up to 1,700 wafers/hour8860 207th Street West Minneapolis, MN 55044 USA© 2012 Despatch Industries.
