Features & Benefits:

  • A unique patent pending inverter design that controls compressor speed and allows for the conversion of compressor power to different working needs.
  • 50% reduction of energy consumption during stabilization process
  • A heat sink applied to increase cooling efficiency
  • 20% less noise than a standard climatic chamber
  • Produced using environmentally friendly materials such as water based paints, no polyurethane in insulation, recyclable/easy disposable packing materials
  • Automatic control system that reduces condenser blower rotating speed according to ambient temperature and cooling power
  • Controller with LCD touch screen panel running KeyKratos software control
