A choice of 4 heating circulators combined with a powerful R4R refrigeration unit offers a cost-effective and efficient solution for low temperature applications down to -30°C.

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 our TX150 or TXF200 heating circulators, offer a number of features:

  • Stability of up to ±0.1°C
  • Up to 3 years warranty
  • No spill valved front drain
  • 3 preset programs
  • Large 20 litre tank and accessible bath for immersion of samples
  • Environmentally friendly refrigerant
  • Robust construction
  • 900W of cooling power
  • Quiet
  • UK designed and manufactured
  • Range of accessory hosing, connectors, software, additional pump and temperature probes available

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.
