A choice of 4 heating circulators combined with a powerful R4R refrigeration unit offers a cost-effective and efficient solution for low temperature applications.
Additionally, Grant also offers the LTC4R kit, which is available as a ready assembled system including TX150 heating circulator mounted on the R4R refrigeration unit and comes supplied with insulated tubing and clips.
The Grant R4R range, which can be combined with any of our T100, TC120, TX150 or TXF200 heating circulators, offer a number of features:
Note: The refrigeration unit can be switched off independently of the heating circulator to allow heating only applications. All the refrigeration base units can be used up to a maximum temperature of 100°C.
Input to enable switching of the cooling system by an external device (typically a Grant Advance Optima).
Temperature range: 2ºC above the temperature of the coolant (Attach to a supply of cooling tap water or a refrigerated circulator)
