Jeio Tech | Refrigerated and Heating Bath Circulator General | With PID Temperature Control, Variable Speed Pump and USB Connectivity
The Jeio Tech Refrigerated Heating Bath Circulator, available at Alto Med Supply, is designed for laboratories that require precise temperature control for both heating and cooling applications.
The RW3-35 models operate from -35°C to 150°C, while the RW3-25 models provide a temperature range from -25°C to 150°C, making them ideal for research, testing, sample preparation, and laboratory circulation processes.
Built with advanced microprocessor PID control, this laboratory bath circulator delivers accurate and stable temperature performance.
Features such as three-point temperature calibration, automatic tuning, and automatic run functions help maintain reliable operation during demanding laboratory applications.
The built-in cooling coil and five-speed adjustable pump reduce fluid turbulence and allow efficient internal and external circulation.
Lower pump settings are optimized for internal circulation, while higher settings support stronger external circulation performance with excellent pressure and flow rates.
The Jeio Tech refrigerated bath circulator is designed for user convenience and long-term durability.
A bright VFD display with a quick-adjust dial allows easy temperature adjustments with 0.1°C resolution.
Additional convenience features include dual wait on/off timer modes, memory storage for up to three frequently used temperatures, and RS-232/USB connectivity for external control and data collection.
The corrosion-resistant stainless steel bath is leak-proof, easy to clean, and includes a convenient drain valve for simple maintenance.
For refrigeration efficiency and easier servicing, the unit features a detachable condenser air filter, removable gridded vent, and quick-release front grill for condenser cleaning.
The system also uses CFC-free refrigerants (R-507 and R-404A) with a double service valve to help reduce leakage risks and support environmentally conscious laboratory operation.
Side handles provide easier transport and installation, while optional LC Connected mobile monitoring allows users to remotely monitor the system through the LC Green Box mobile monitoring platform.
Safety is a major focus of the Jeio Tech Refrigerated Heating Bath Circulator. The agitator, heater, and sensor are separated by a protective baffle plate to minimize turbulence and reduce direct contact with internal components.
The unit also includes a complete safety protection system with alarms for low fluid level, dry-running, over-temperature, and over-current conditions.
A keypad lock function helps prevent accidental setting changes during operation for added laboratory safety and reliability.

What a life saver. The chair arrived in a big box. Was very easy to assemble. Just unfold and attach the foot pedals. Mom is now able to cruise around her complex visiting friends and participating in activities.
This bed is brilliant, and the technology is brilliant. It is a stunning bed that has helped mobility for my wife who has a spinal cord injury and has trouble getting in and out of bed as well as chairs. Her quality of life will be better because of this product.Thank you.
