R4 Series Refrigerated Circulating Tank
The Grant R4 range of refrigerated baths and circulators offers exceptional performance for routine and sophisticated applications requiring accurate temperature control in the range of -30 to 100°C. A choice of 4 heating circulators combined with a powerful R4 refrigeration unit provides an economical and efficient solution for low-temperature applications.
Additionally, Grant also offers the LTC4 kit, available as a pre-assembled system that includes the TX150 heating circulator mounted on the R4 refrigeration unit and comes with insulated tubing and clips.
The Grant R4 range, combinable with any of our T100, TC120, TX150, or TXF200 heating circulators, offers numerous features:
- Stability up to ±0.1°C
- Up to 4-year warranty
- Front drain with non-spill valve
- 3 preset programs
- Large 20-liter tank and accessible bath for sample immersion
- Environmentally friendly refrigerant
- Robust construction
- 900 W cooling power
- Quiet operation
- Built in Great Britain
- Available range of accessory tubing, connectors, software, additional pump, and temperature probes
Note: The refrigeration unit can be switched off independently of the heating circulator to allow for heating-only applications. All refrigerated bases can be used up to a maximum temperature of 100°C.
Applications
- University research/teaching - temperature control of external equipment including: spectrophotometers and refractometers. Circulation of temperature control fluid to jacketed vessels, cooling crystallization vessels
- Industrial laboratories: temperature probe calibration, product testing, product quality control, temperature control of external equipment.
