PE-1600 Batch Pre-Expander — eps pre-expanders by ChinaEps, CE & ISO 9001 certified.
The PE-1600 is a high-capacity batch pre-expander for large-scale EPS production. With a 1,600mm barrel and output of 1,000-1,300 kg/h, it is designed for demanding production environments. Multi-zone steam injection ensures uniform bead expansion across the entire batch.

Three production problems eliminated by this machine — with engineered, measurable solutions.
High-volume EPS factories hit throughput ceiling on PE-1400 at ~5,000 t/year
PE-1600 (1,000-1,300 kg/h, 37 kW) doubles capacity — supports plants targeting 6,000-10,000 t/year output without dual-line CAPEX.
Larger barrels at low steam pressure cause uneven expansion at edges vs center
PE-1600 uses 0.20-0.25 MPa working pressure (vs 0.18-0.23 MPa on PE-1400) and dual-zone steam injection — uniform expansion across the full 1,600 mm barrel diameter.
Eight engineered subsystems that make this cutting line production-grade. Each component is sourced, built, and tested for industrial duty cycles.
Large 1,600mm expansion chamber for 1,000-1,300 kg/h throughput — bridges the gap between mid-range PE-1400 and premium PE-1800.
304 stainless inner shell + 50mm mineral wool insulation. Working pressure 0.4 MPa. Pre-heat 10-12 minutes. Designed for 24/7 operation in high-volume factories.
6 steam injection ports (vs 4 on PE-1400, 8 on PE-1800) — uniform expansion across the 1,600mm barrel volume.
PLC-controlled valve per zone. Closed-loop pressure regulation 0.20-0.25 MPa. Steam recycling captures condensate — 25-30% energy savings.
Higher-torque agitator for the larger batch volume. Bottom-driven design with dual bearings for extended service life.
4-blade 316 stainless agitator, 8.5 kW SEW Eurodrive + 25:1 reducer. VFD 12-45 RPM. Dual-bearing extends seal life to 11,000+ hours.
Same precision weighing as PE-1800. ±40g accuracy for high-volume production where every batch counts.
±40g accuracy via German HBK load cells. PLC stores 50+ recipes. Recipe-switch under 60 seconds with audit-trail logging.
Siemens S7-1500 PLC with SCADA gateway — same data export capability as PE-1800 for MES/ERP integration.
Siemens S7-1500 PLC, 12" Weintek HMI. SCADA gateway (Ethernet/IP, OPC UA, Modbus TCP). Fault log 5,000 events.
Built-in fluidized dryer (not optional like PE-1400) — gently dries freshly expanded beads before aging silo.
Vibrating perforated tray, hot-air flow at 40-50°C, bead dwell 6-10 minutes. Cyclone separator captures fines.
Roots blower-based conveyor sized for the larger discharge rate. Ø180mm duct (between PE-1400 Ø150 and PE-1800 Ø200).
Anti-static design (ATEX zone-22 compliant). Diverter valves for multi-silo routing. Cyclone at silo inlet — 99% capture.
CE-compliant safety circuit. Optional ATEX zone-22 upgrade for FR-EPS dust environments.
Pressure relief at 0.32 MPa. Steam interlock. Three e-stop mushrooms. Thermal cutoff. Optional ATEX grounding kit for FR production.
Every advantage backed by measurable specs — no marketing claims without data.
40% throughput uplift vs PE-1400 — no second pre-expander needed up to 10,000 t/year.
Higher pressure rating + dual-zone injection ensures uniform expansion across larger barrel.
Pairs with BM-1600 / BM-1800 block-molding lines for high-output insulation board factories.
This machine is widely used across multiple industries and production scenarios.
A clear schedule keeps the line running. Built-in safety systems protect operators and product alike.
Inspect 6 steam manifold valves. Clean weighing hopper. Check HMI fault log. Verify agitator + fluidized dryer operation.
Inspect agitator dual bearings. Lubricate reducer (NLGI-2, 60g). Drain steam condensate from all 6 zones. Test load cell calibration.
Clean barrel interior. Recalibrate steam pressure transducers per zone. Service cyclone filter. Backup PLC recipes and production logs.
Replace water-ring vacuum pump seal. Inspect dual-bearing assembly. Verify safety relief at 0.32 MPa. Service SCADA gateway.
Major overhaul: replace dual bearings + mechanical seal, recalibrate all 6 steam zones, recertify safety circuit per EN ISO 13849-1 PLd, update Siemens PLC firmware.
