🔧 Choosing the Right Chiller

1. Determine your laser type and power: CO₂ glass tube, RF CO₂, or fiber; power level.

2. Check cooling capacity vs heat output of the laser source.

3. Required temperature control accuracy (±0.3 °C vs ±1 °C).

4. Flow-rate or pump pressure needs to circulate coolant effectively.

5. Voltage & frequency compatibility: 50 Hz / 60 Hz, 110–120 V vs 220–240 V or 380 V.

6. Size and footprint: CW‑5000 is compact; CW‑6300 / CWFL are larger.

7. Extra features: RS‑485 connectivity, built-in heater, filter, caster wheels.

📌 Summary

• For CO₂ glass tube lasers (~80–150 W) → CW‑5000 Series: compact, active cooling, ±0.3 °C.

• For high-power CO₂ or fiber lasers (kW-level) → CWFL or CW‑6300 Series: large cooling capacity, dual control, robust flow & temperature handling.

• The CWFL fiber series is ideal if you have medium to high-power fiber lasers and need precise dual-circuit cooling.
