 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) – Cat.No. JTH-AAH52306U
CW-10G (10.0L) – Cat.No. JTH-AAH52316U
CW-20G (20.0L) – Cat.No. JTH-AAH52326U
CW-30G (30.0L) – Cat.No. JTH-AAA52336U
Operating Features:
- 5°C above room temperature to 150°C
- Uniformity ±0.1°C at 50°C (based on various conditions)
- Microprocessor 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°C resolution) with splash-proof keypads
- RS-232 interface available
Constructional Features:
- Exclusive variable-speed pump 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°C but in 4 and 5 steps, the range will be from Amb. +15°C.
2) The heat-up time is measured on a 230V electrical condition with 1000W heater power.
3) The additional suction function is optional. |
