What Kind of Industrial Computer Does a Smelting Workshop Need?

From Harsh Environments to Real Value — The True Worth of CESIPC Fanless Industrial PCs

1. Who Are Our Customers?

If you search “smelting workshop industrial computer,” “high-temperature industrial PC,” or “dustproof and shockproof industrial computer” on Baidu or Google, you’re likely one of the following:

• Smelting plant equipment engineers – responsible for upgrading production control systems, focusing on equipment lifespan and compatibility.
• Automation system integrators – providing complete control system solutions for smelting or casting customers, pursuing a balance of reliability and cost.
• Information/digital transformation managers – implementing MES/SCADA systems, requiring terminals that can run stably in high-temperature, dusty environments.

All of you share a common need:

A long-term stable industrial computer that can continuously collect, transmit, and process data in the harsh conditions of a smelting workshop.

2. How Harsh Is the Smelting Workshop Environment?

After conducting field surveys in 47 foundries and smelting plants, we found the following typical characteristics:

Environmental Factor	Typical Data	Impact on Industrial Computer
Dust concentration	0.3–0.9 g/m³	Fan draws in dust → motherboard short circuit
Ambient temperature	45–70 °C	Regular computers crash easily
Power fluctuation	±35 %	System restarts, data loss
Vibration/shock	> 2 G during crane operation	Loose drives and connectors
Oil/moisture	Persistent	Corrodes metal connectors and circuits

In such conditions, any commercial computer with a fan or mechanical hard drive usually fails within three months.
That’s why fanless industrial PCs are essential for smelting workshops.

3. What Makes an Industrial PC Run Reliably in a Smelting Workshop?

(1) Fanless Design – Complete Dust Protection

If the dust can’t get in, the machine won’t break.

---

(2) Wide Temperature Range – Excellent Heat Resistance

Near furnaces or smelting areas, ambient temperature often exceeds 60 °C.
CESIPC industrial PCs use industrial-grade wide-temperature motherboards and solid-state drives (SSD) to ensure stable operation between −20 °C and +70 °C.

Specification	Regular PC	CESIPC LEGO Industrial PC
Cooling	Fan	Full-aluminum passive cooling
Operating Temp.	0–40 °C	−20–70 °C
MTBF	5,000 hours	≥ 50,000 hours

---

(3) Wide Voltage Power Design – Stable Against Power Fluctuations

Power instability is common in smelting plants, with voltage fluctuations of up to ±35 %.
LEGO series PCs support 9–36 V wide-voltage input, featuring:

• Over-voltage/under-voltage protection (OVP/UVP)
• Short-circuit protection (SCP)
• Automatic restart (Power Restore)

Even after sudden power loss, the system automatically recovers without file corruption — critical for MES, PLC data collection, and SCADA monitoring.

“No power interruption” is the foundation of stable production.

(4) Modular Interfaces – Flexible Connectivity

Data collection in smelting workshops often involves temperature sensors, PLCs, weighing devices, and upper-level systems.
CESIPC industrial PCs provide rich expansion interfaces:

• 6 × COM (RS232/422/485 selectable)
• 4 × USB 3.0
• Dual Gigabit LAN
• HDMI + DP dual display output
• Optional Wi-Fi/4G/5G modules

Whether for automation control or production data acquisition, one device covers all communication needs.

6. Conclusion

In a smelting workshop, the requirement for an industrial PC is not just to “turn on,”
but to run stably and reliably for years in harsh conditions.

The CESIPC LEGO Series Fanless Industrial PCs deliver that with robust construction,
reliable power design, and wide-temperature operation — ensuring every data point is trusted
and every system runs continuously and safely.

Stability is true value.
