Recirculating Coolers (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.

▶ Refrigerating system is designed to reduce energy consumption and maximize refrigerating efficiency.



● Convenience


▶ Designed to simplify operation with a touch screen type display.

- Easy-to-read VFD display with interactive touch keys.

- Setting and resolution indication 0.1°C/°F.

- Quick keypad lock prevents accidental parameter changes.

- Signal indicator for operation status.

▶ Bright LED water level indicator can be seen from a distance.

▶ 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.



● 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.
