 BATH

 

 Low Temp. Bath Cirulator

 

 

 

 

Rapid heating and cooling throughout the entire temperature range!
RW-G series has powerful circulation pump for external and internal circulating. The temperatures can be down to maximum -35 that maintain and control accurate low temperatures for use with Refractometers and Viscometers.

 

 

Performance Features

Operating features
• -25 to 150 for RW-25G/ -35 to 150 for RW-40G
• 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
• Turbulence reduced five-speed duplex pump and built-in cooling coil let you use in open or closed bath applications (1 to 3 steps of pump for internal circulation/ 4 and 5 steps for external circulation)
• 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
• Use CFC-free refrigerant R-134A, R-404A and double service valve to prevent the leakage of refrigerant
• Quick-release front grille for easy condenser cleaning and space saving design uses minimal bench space
