Category Chillers
Manufacturer Jeio Tech
Country of manufacture South Korea
Overview

Adjustable, precise PID temperature controller beneficial for various cooling tasks in the science, research, and industrial laboratories.
Models: HS-15/20/25/35/45/45H/55/55H

Performance

  • Temperature range from -20°C to 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.

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.

Please note: Jeio Tech recirculating coolers are generally not stocked in the US, are built-to-order in Korea, and are shipped via ocean freight. An 8-12 week lead time should be expected.
