Daihan Electric Classic Water Still, 3.5Lit/hr, CWS-4, 220V DH.WatS8001

Electric Classic Water Still CWS-4 (DH.WatS8001) is a laboratory water distillation unit that produces up to 3.5 Liters per hour of distilled water. The unit is designed with all stainless-steel construction and a double-walled chamber to provide safe, continuous production of laboratory-grade distilled water (resistivity 0.3 MΩ·cm, pH 5.4–7.3). The CWS-4 includes a built-in PP 1 µm cartridge prefilter, automatic heater on/off controlled by water level and micro-level sensors, and operates on 220 V, 50/60 Hz for single-phase electrical supply. It is intended for routine laboratory distillation and water purification tasks where a compact, automatic still is required.

Key Features:

• Capacity: Max. 3.5 L/hr
• Power: 3 kW, Electrical requirements 220 V, 50/60 Hz, 1 Phase
• Water purity: 0.3 MΩ·cm (resistivity), pH 5.4–7.3
• Construction: Interior and condenser stainless-steel; exterior stainless-steel hair lined with powder coating; double-walled chamber
• Built-in PP 1 µm cartridge prefilter (removes rust, particles, scale-forming impurities)
• Controls & Safety: Auto On/Off with water level sensor and micro-level sensor; low-water and over-temperature protection; electric leakage circuit breaker
• Cooling water requirement: 30–50 L

Advantages:

• Consistent laboratory-grade distilled water output (3.5 L/hr) with specified resistivity and pH for routine lab use
• Integrated 1 µm prefilter and stainless-steel construction reduce corrosion and particulate contamination, simplifying maintenance
• Automatic level control and built-in safety protections (low-water, over-temperature, leakage breaker) enable unattended, safe operation
