WATER BATH CW-20G

Circulating Water Bath อ่างน้ำร้อน อ่างน้ำวน ควบคุมอุณหภูมิ CW-20G ขนาด 20 ลิตร

External and internal circulating with powerful pumping capacity CW-G series is designed for controlling temperature in external instrumentation, or for immersion application. Pump pressure is adjustable in five stages and all models come with built-in tab water cooling coil.

CW-05G (5.0L) CW-10G (10.0L) CW-20G (20.0L) CW-30G (30.0L)

Operating features
• 5℃ above room temperature to 150℃
• Uniformity ±0.1℃ at 50℃ (based on various conditions)
• Microprocess PID control/ Auto-tuning/ Calibration
• Digital timer: 1 min to 99 hr 59 min, delayed ON/ OFF
• Over-temperature limiter and low fluid level protection
• 3 different temperature values memorable without auto-tuning
• Digital LED display (0.1℃ resolution) with splash-proof keypads
• RS-232 interface available

Constructional features
• Exclusive variable-speed pump to liquid viscosity for accurate, stable, and efficient temperature management
(1 to 3 steps of pump for internal circulation/ 4 and 5 steps for external circulation)
• Powerful pressure and suction pumps provide contrast pressure and flow rate over the full temperature range
• Baffle plate screens circulating pump, heater and sensor to minimize shaking bath fluids and protect sample and
operators from direct contact
• Dry-running protection; automated heating element cut-off and audible and visual warning
• Seamless stainless steel tank with a reservoir drain that resists corrosion and make cleaning easy
• Space saving design uses minimal bench space

1) If you operate the unit in 1 to 3 steps of pump, the temperature range can be from Amb. +5℃ but in 4 and 5 steps,
the range will be from Amb. +15℃.
2) The heat-up time is measured on a 230V electrical condition with 1000W heater power.
3) The additional suction function is optional.
