RakworX’s Natural Air Cooling Modular Data Center: E2F-R4-44TR

RakworX’s EDGEASY free natural cooling module is a prefabricated and efficient data center solution. A-rack’s natural cooling solution integrates multiple physical infrastructure subsystems; all components are fully prefabricated and tested in the factory before it is delivered to the customer site. RakworX natural cooling module helps customers realize rapid deployment, end-to-end one-stop delivery and digital operation and maintenance through intelligent management and operation software.

Greater Flexibility Modular Construction
lFully modular design

lExpandable as needed

lSaves time & Money on expansion enabling rapid deployment for scaling up with your business

lIdeal for Hospitals, Universities, IT companies, and Edge Computing Sites.

lProvides the best balance for IT components, cooling and management systems within a single module.

lUtilizes standard 19” 42U server racks

lEnsures everything fits and functions properly

Fully Prefabricated More Energy Efficient
lAll components are precision-engineered, factory tested and integrated to ensure a perfect fit.

lEasier, faster and more accurately assembled on site

lIdeal for both indoor and outdoor applications

lSaves time on design, manufacture and installation which saves money


lUses natural outside air, evaporative cooling in addition to cold & hot dual-aisle containment

lGrade G2 pre-filter removes impurities such as dust from the air

lGrade F8 mid-filter thoroughly filters chemical pollutants protecting IT equipment from sulfide and nitrogen oxide erosion

lDifferential pressure sensors let you know when it’s time to replace the filters-no guseeing or wasting time

lAchieves an average annual PUE(Power Usage Effectiveness) lower than 1.1
