12 Zone Reflow Oven Machine Technical Data
Lyra934 is the large Lyra platform for factories that need more process length than Lyra622 or Lyra733. The 4460mm heating section, 12 heating zones, and 4 separate cooling zones make it suitable for large reflow oven projects, SMT precision lead-free reflow oven applications, and lines that need stronger cooling margin after peak soldering. The nitrogen configuration can be reviewed according to PCB width, line speed, oxygen target, and factory airflow.

Large Reflow Oven For Mass SMT Production
Lyra934 is selected when a factory needs the largest Lyra process window for continuous SMT production. The longer heating tunnel helps engineers slow down thermal transitions, keep peak time under control, and protect complex assemblies when line speed and board thermal mass increase.
For manufacturers building communication infrastructure, automotive electronics, industrial power controls, server hardware, LED modules, or high-mix assemblies, Lyra934 gives a larger lead free reflow oven machine platform without moving into a special custom oven project.
12-Zone Lead-Free SMT Process Control
Lyra934 is not just a longer machine body. Its 9 preheating zones, 3 peak heating zones, 4 cooling zones, and nitrogen-ready process chamber help factories protect solder quality when board size, copper weight, carrier design, or production takt changes.
12 Heating Zone Process Margin
The 4460mm heating section supports smoother ramp, soak, peak, and cooling transitions for larger or thermally demanding boards.
Mass Production Fit
Lyra934 fits SMT lines where output volume is rising and the oven must keep profile repeatability over longer production runs.
Nitrogen Cost Control
Nitrogen planning can be matched to PCB width, board gap, throughput, and oxygen target instead of using a fixed guess.
Lyra934 12 Zone Reflow Oven Features
12 Heating Zones And 4460mm Heating Length
Lyra934 is the longest Lyra model in this group. Its 9 preheating zones and 3 peak heating zones give process engineers more space to shape ramp, soak, and peak behavior before the board enters the cooling section.
- 4460mm heating section for larger thermal process margin
- 12 heating zones counted separately from cooling zones
- Designed for higher-capacity lead-free SMT production
Nitrogen Sealing For Low-Oxygen Reflow
When Lyra934 is ordered with nitrogen configuration, sealing at the process chamber and transfer openings becomes important. This structure supports controlled oxygen conditions for solder wetting, oxidation reduction, and repeatable large-line operation.
- Peak-zone oxygen target below 500ppm under nitrogen conditions
- Sealing design helps reduce unnecessary nitrogen loss
- Nitrogen planning can be matched to PCB width and line speed
Stable Rail Transport For Large PCBs
A long reflow oven needs steady board movement from inlet to outlet. Lyra934 supports controlled rail width, chain transport, and conveyor speed adjustment so larger PCBs and carriers move through the heating tunnel without disturbing the profile.
- Standard single rail 50-460mm with wider rail options
- Dual-rail planning can be reviewed for suitable line layouts
- 300-1800mm/min conveyor speed supports capacity and profile tuning
Flux Residue Management And Exhaust Cleaning
Higher-volume lead-free production can increase flux load inside the oven. Lyra934 supports residue management and exhaust planning so maintenance work, chamber cleanliness, and process atmosphere remain easier to control.
- Designed for cleaner long-run reflow oven operation
- Helps reduce flux buildup around process and exhaust areas
- Supports maintenance planning for multi-shift production
Four Cooling Zones For Large Reflow Lines
Lyra934 uses 4 cooling zones after the 12 heating zones. This gives larger SMT lines more post-peak cooling margin when board mass, carrier design, solder paste behavior, or downstream handling requirements are more demanding.
- Cooling section supports controlled post-peak temperature drop
- Water and air cooling configurations can be reviewed by project
- Helps protect large boards before transfer to downstream equipment

Lyra934 Factory Support And Project Service
For Lyra934 projects, I.C.T reviews capacity targets, PCB width, expected thermal load, nitrogen usage, exhaust volume, cooling-water conditions, and upstream or downstream SMT equipment before final confirmation.
Before delivery, the oven can be checked around heating response, conveyor movement, cooling behavior, control functions, alarm logic, electrical safety, and ordered options. This gives large-line customers a clearer startup path when the equipment reaches the factory.
I.C.T Project Capability
Large reflow projects need technical review before price confirmation. This process view shows how I.C.T handles line review, production, testing, delivery, and compliance proof before Lyra934 enters the SMT line.

Large Reflow Oven FAQ
Use these questions to check whether Lyra934 matches your line speed, PCB width, nitrogen target, cooling requirement, and lead-free soldering process before sending the inquiry.
What makes Lyra934 different from smaller Lyra ovens?
Lyra934 is the large Lyra platform with 12 heating zones, 4 cooling zones, and 4460mm heating length. It gives more room for ramp, soak, peak, and cooling control than Lyra622 or Lyra733 when the SMT line needs higher capacity or a larger thermal process window.
Is Lyra934 a 12 zone reflow oven machine?
Yes. Lyra934 has 12 heating zones: 9 preheating zones and 3 peak heating zones. It also has 4 cooling zones after soldering, with a 4460mm heating section for wider profile control.
When does nitrogen matter on a large reflow oven?
Nitrogen is useful when oxidation control, fine-pitch solder wetting, high-reliability solder joints, or dense component layouts make normal air reflow less stable. For Lyra934 projects, the oxygen target should be reviewed together with PCB width, board gap, solder paste, and line speed.
Can Lyra934 work as a Dual-rail SMT Reflow Oven?
Lyra934 uses a standard 50-460mm single-rail range. For wider products, carriers, or future product families, I.C.T can review 50-686mm or project-specific width planning. Dual-rail SMT Reflow Oven layouts can also be discussed for suitable production lines.
Can Lyra934 be used for lead-free SMT production?
Yes. Lyra934 supports SMT precision lead-free reflow oven production with preheating zones up to 300°C and peak zones up to 350°C. The 4460mm heating section gives engineers more room to tune a stable lead-free profile.
How much nitrogen is used in reflow oven production for Lyra934?
For the largest Lyra configuration, the PDF reference lists approx. 35m3/h under single-conveyor conditions below 1000ppm in the peak zone, based on max. PCB width 200mm and PCB gap 50mm. With N2-control in standby mode at 200mm transport width, the reference value is approx. 32m3/h. Final usage depends on PCB width, throughput, oxygen target, and factory airflow.
Can I.C.T support Lyra934 profile setup?
Yes. For Lyra934, I.C.T can review heavy-board requirements, solder paste data, target UPH, oxygen level, and cooling needs, then support profile tuning, startup training, and later product-change adjustment.
