Recirculating Coolers (Advanced Low Temp.)

Adjustable, precise PID temperature controller beneficial. For various cooling tasks in the science, research, and industrial laboratories.


Different specifications and extras available. 


  • Temperature range from -20°Cto 40°C.
  • High cooling capacity up to 7.1kW at 20°C.
  • Powerful circulating pumps up to70L/min., 6 bar.
  • Precise temperature stability ± 0.2°C(at 15°C) without heater.
    – Innovative and exclusive controller can adjust the cooling capacity from 1% to 100%.
  • Refrigerating system is designed to reduce energy consumption and maximize refrigerating efficiency.



  • 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.
