NE4-8HT

Clifton® Digital Water and Oil Heating Circulators designed for external circulation of temperature-controlled water and heat transfer fluids in a closed circuit or maintaining a stable temperature environment in the bath for the immersion of flasks/bottles/racks.

The stainless steel tank contained within a sturdy outer case and supplied complete with a stainless steel shelf all providing good water circulation and temperature stability.

The Thermocirculator is robustly constructed from stainless steel for durability. Painted surfaces feature a tough anti-bacterial finish with good chemical resistance. Easy to use controls that wipe clean and have an anti-bacterial finish. Immersed components are corrosion resistant. Quiet running in use and providing excellent water temperature stability in the bath. Indication of heating, over temperature alarm and timer running.

When a low liquid level is detected a “FiLL” message automatically appears and heating is suspended. Once refilled, heating is restored and temperature control resumes automatically.

Over and under temperature alarms automatically protect work in the water bath, providing heater cut off, visual message and indicator. Additionally a Safety Experiment protector can be set just above desired working temperature protecting your work.

Thermocirculator pump comes with convenient push-fit and lock fittings on both inlet and outlet ports for secure external water circulation.
 

Featuring bold LED display of measured temperatures in real-time, increments of ±0.1°C, using precision PID temperature control. Setting for water temperature only or combination of temperature and time. Timer setting variable in 1-minute increments from 00:01 [hh:mm] to 99:59 [hh:mm] with “end” message on completion-timed period. Settings retained even after turning the unit off.

Easy to use splash proof controls, touch keypads for setting time and temperature values with indicators for heating, over temperature alarm and timer. Bold digital LED display.

The water bath can be set to run at a set temperature or commence the timer once the water reaches set temperature.

Features auto setting over and under temperature alarm protecting your work at set temperature.

A Safety Experiment protector can be set just above desired working temperature protecting your work.

Every unit undergoes a factory calibration at two temperatures for validation.

Features a low liquid level float switch, which ensures heating, is switched off if the liquid falls below the recommended level - display will show “FiLL”. Heating is switched off but stirring continues. To reset carefully top up the liquid to the recommended level.

The under/over temperature alarm is automatically set 4˚C above and 4˚C below set temperature. When in alarm condition the indicator illuminates and actual bath temperature is shown, if bath is over temperature both heating and stirring are switched off. Once liquid temperature has fallen or risen above/below the alarm setting the indicator clears and actual bath temperature is shown.

Class 2 protection features a Safety Experiment protector can be set just above desired working temperature protecting your work.

For water temperatures below ambient we recommend a glycol/water mix or accessory solution LB-5.0 Lab Bath, accessory lid or spheres fitted to retain the cold and an accessory Immersion Cooler. Recommend operating in ambient temperature 20°C.

For water temperatures above 60°C we recommend accessory lid or spheres fitted for optimal performance, reduces evaporation and also assists keeping water free from contamination and saves energy reducing electricity consumption and running costs.

100% water: 5°C to 99°C

50% water 50% glycol: -20°C to 90°C

Lab Bath 4590: -15°C to 90°C

Silicone oils, up to 10 centistokes, synthetic thermal liquids: 99°C to 130°C.

0.5kWh @ 37°C

The lower the figure, the less energy used. Information supplied for size and range comparison, guidance only and measured consumption at set point. Please remember that the energy consumption may vary due to factors such as its location, ventilation, ambient temperatures and loading.

3 Years

1. Heated Circulating Clifton water baths are ideal for external water circulation or immersion of flasks/bottles/racks in a highly stable temperature environment throughout the water bath. 2. Good water movement and temperature control provides temperature stability throughout the water bath. 3. Three-year warranty and comprehensive customer support. 4. Broad range of accessories available to suit wide range of applications. 5. Before leaving our factory each water bath has a unique serial number, electrically tested for safety at final inspection and a test certificate enclosed in rear of the instruction book. 6. To verify the performance of the temperature control system every unit undergoes a factory 2 point calibration procedure adjusting control to known traceable values. 7. Thermocirculator controls and painted surfaces feature “anti-bacterial technology” which inhibits bacterial growth, improving hygiene requirements as demanded by many clinical and laboratory environments. These hygienic surfaces are part of a controlled approach to cleaner facilities. The Clifton range features easy to clean surfaces and finishes that are resistant to routine and efficient disinfection’s. The efficacy of the finish is maintained over time, as the anti-bacterial agent is integral within the finishes.
