  • Wide temperature range from -20°C to 80°C.
  • High cooling capacity up to 7.1kW at 20°C.
  • Powerful circulating pumps up to 70L/min., 6 bar.
  • Precise temperature stability ± 0.1°C(at 15°C) with integrated heaters.
  • Refrigerating system is designed to reduce energy consumption and maximize refrigerating efficiency.

Convenience

  • Designed to simplify operation with a touch screen type display.
    • Setting and resolution indication 0.1°C/°F.
    • Quick keypad lock prevents accidental parameter changes.
  • Bright LED water level indicator can be seen from a distance.
  • Optional external sensor can be connected for more actual temperature control.
  • Built in pressure gauge for checking pump pressure at a glance.
  • High/low pressure gauges for condition diagnosis of refrigerating system at a glance. (for H type)
  • Wide filling inlet for easy and safe pouring of solution into the unit.
  • Double service valve prevents refrigerant leakage for easy maintenance.
  • Removable gridded vent for easy maintenance of condenser.
