Next Generation Direct Air Cooling (DAC)
Direct Air Cooling (DAC) is an industry-leading fan based direct air cooling system providing low-maintenance, energy-efficient and environmentally friendly cooling options for equipment cabinets and shelter enclosures. It works by bringing outside fresh air to the equipment in an energy-efficient, controlled and clean method.
DAC solutions from RFI consistently deliver clean, reliable cooling. They are proven to reduce cooling electricity by over 75% compared to traditional HVAC systems. They are DC powered thus eliminating interruptions during power outages. DACs qualify for energy rebates and green initiative programs.
