Recirculating Coolers (Advanced Low Temp.)



● Performance

▶ 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.


● 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.
▶ Built-in casters for easy transport and installation.
▶ RS-232 interface for external control and data collection.
▶ Monitor via mobile app anytime, anywhere with LC Connected (mobile monitoring system) connection. (when purchased LC GreenBox)




● Safety

▶ Self-diagnostic function identifying errors.
▶ Complete safety protection system with warning alarms.
- Low fluid level and dry-running protection; when triggered shows an error symbol on the display and an audible buzzer sound.
- Over-temperature protection; If the equipment operates at over maximum temperature due to external environment, user can simply identify the error with a visual signal or an audible buzzer sound.
- Over-current circuit breaker.
▶ Eco-friendly R-404A / R-507 refrigerant use for environmental protection.
▶ Splash-proof keypad.
