GD120 R series Refrigerated bath

The Grant Optima™ GD120 R series of refrigerated baths and re-circulators with digital control provides excellent value for money for more demanding applications requiring accurate heating and cooling in the range of -20 to 100°C.

Grant GD120 series refrigerated systems combine the versatile Grant Optima™ digital immersion thermostat GD120 with a choice of five Grant refrigerated stainless steel tanks.

The GD120 immersion thermostat incorporates Intelligent Control Optimisation (ICO)™ for adaptive intelligent PID temperature control and includes a powerful integral pump, making GD120 series refrigerated systems suitable both for immersing samples and circulating temperature controlled fluid to external devices. It includes a convenient timer function for reaction timing and a variable high temperature alarm setting. The temperature range and heater power are automatically limited according to the liquid type selected.

  • Simple-to-use rotor plus two keys provide access to the interactive interface for fast, accurate set-up
  • Clear digital display for instant reassurance - easy to read from a distance
  • Visual and audible alarm - alert you when your attention is required
  • Operating setpoint plus 3 adjustable preset temperatures for convenience
  • User calibration facility for optimum accuracy at the required operating temperature
  • Powerful integral pump - maximum flow rate 17L/min
  • Choice of five refrigerated (R) tanks with different facilities, working volumes and cooling capacities
  • Cooling/heating range: -20 to 100°C
  • Stability ± 0.1°C

Note: The refrigeration unit can be switched off indepedendently of the thermostat to allow heating only applications. All the refrigeration base units can be used up to a maximum temperature of 100°C.

Tank Option

The Grant Optima™ GD120 R series of refrigerated baths and re-circulators provides a choice of five models with different facilities, stainless steel tank capacities and cooling power to suit different applications.
