Cooling water circulation device (high-end low-temperature type)

Digital display controller

RS-232 interface, etc

Performance Characteristics

• Temperature range: -20 ℃~40 ℃
• The maximum cooling power is 7.1 kW at 20 ℃.
• The maximum flow rate of the circulating pump is 70L/min. and the pressure is 6.0 bar.
• Accurate temperature stability without heating: ± 0.2 ℃ (at 15 ℃)
  -Innovative and unique controllers can adjust cooling capacity from 1% to 100%.
• The cooling system can reduce energy waste and achieve maximum cooling effect.

Easy to operate

• Simplified VFD touch screen for operation.
  -Set the resolution to 0.1 ℃/℉
  -Quick keyboard lock function to prevent unauthorized operations.
• The LED liquid level indicator can also be seen from a distance.
• Optional external temperature sensor for more precise temperature control.
• Built in pressure gauge, which can clearly show the pressure of the pump at a glance.
• The high/low pressure gauge can clearly check the status of the refrigeration system at a glance.(Applicable to H series)
• The spacious inlet allows for easy and safe pouring of the solution into the system.
• Two backup valves can prevent coolant leakage.
• Mobile grid vents can reduce contamination of the condenser.
• Standard casters for easy installation and movement.
• The RS-232 interface can be used for external control and data collection.

Safety features

• Automatic diagnostic function, automatically identifying errors.
• Safety protection function with signal alarm.
  -Low liquid level and no bath protection, there will be an alarm sound to remind when there is an error signal on the display.
  -Over temperature protection, if the device experiences over temperature due to external environment, an audible and visual alarm reminder signal will appear.
  -Current overload protection.
• The environmentally friendly R-404A/R-507 coolant can prevent environmental pollution.
• The keyboard can prevent splashing with shower gel
