Read the exact nylon’s drying instructions before buying. An 85°C ceiling does not meet a 100°C cycle merely because the dryer has a Nylon preset. The spool must tolerate the cycle too.
Use the temperature requirement as an eligibility gate
| Documented requirement | Eligible direction | What still needs checking |
|---|---|---|
| A complete cycle within the dryer’s range, no higher than 85°C | S4 Pro or SH03 can be considered | Two-spool chamber fit, time control and actual material instructions |
| A verified cycle above 85°C and within 110°C | E2 is the higher-temperature candidate here | Supplied revision, spool heat tolerance and useful interior clearance |
| A range without a duration, or conflicting roll instructions | Resolve the complete cycle first | A maximum temperature is not a drying procedure |
Four rolls are not always more useful than two
A mixed bench may benefit from the Pro or SH03 preparing separate material pairs. A smaller number of rolls needing a higher-temperature cycle points toward E2 instead. Reports of successful PA6-CF preparation support considering E2, but they do not qualify every nylon formulation or oversized spool.
Use the nylon drying guide to prepare the material, and the nylon material shortlist if the formulation itself is undecided. The S4 versus E2 comparison explains why ordinary four-roll capacity and hotter preparation are separate purchases.
