Motivair Chilled Door Rack Cooling System

Server heat densities are increasing rapidly in government, institutional, financial and co-location applications, while HPC systems are designed to provide increased computational speeds within limited rack space. The Motivair Chilled Door® Rack Cooling System manages the critical cooling requirements of higher density server racks which cannot be effectively cooled with traditional air conditioning, in-row coolers or passive rear door coolers - and at the lowest possible energy cost.

The latest Motivair Chilled Door® is an "active" hinged door that replaces the rear door of any standard or OEM server rack via an interface frame. The Chilled Door® is capable of removing up to 45 kW per rack with 65F supply water, using less than 500 watts of fan power. Over 50 different variables are constantly monitored and controlled via a custom PLC to ensure that the Chilled Door® is actively adjusting to conditions inside the data center and the server rack. By actively removing 100% of the heat load at its source, the Motivair Chilled Door® system results in a "Heat Neutral" white space that requires little or no air conditioning. Hot aisle/cold aisle configurations are eliminated, data center square footage is reduced, raised floors are optional and energy efficiency can be increased by up to 90% compared to legacy cooling systems. The Motivair Chilled Door® always operates above the dew point of the data center, which eliminates the possibility of condensation near critical electrical equipment. 100% sensible cooling eliminates wasted energy by CRAC units or in-row coolers via accidental de-humidification and re-humidification. As a result, no condensate pumps or piping are required. The Chilled Door® was designed with an aluminum coil frame to reduce weight and eliminate zinc whiskers".
