Minimus servers come integrated within Green Revolution Cooling’s CarnotJet System, a rack based immersion cooling system that delivers industry leading performance and efficiency. The servers are installed vertically in the special racks, which are filled with a dielectric coolant called ElectroSafe, an electrical insulator with 1,200x more heat capacity by volume than air.
The CarnotJet System is the most efficient cooling system available to data centers. The system cuts cooling overhead down to below 5%, resulting in a mechanical PUE of less than 1.05.
Improved Server Performance and Reliability
The CarnotJet system creates and maintains the ideal environment for servers helping improve their performance and reliability. This is made possible by:
- Superior Thermal Management: The CarnotJet System maintains a very stable and uniform cooling environment for the servers that is controlled to ±1° C throughout the Rack.
- Protection from dust, moisture, and oxidation: Servers immersed in the ElectroSafe Coolant stay protected from dust, moisture, and oxidation, which are known to be among the leading causes of failure of IT equipment.
- Reduced Vibrations: The removal of chassis fans along with the dampening effect of the fluid help reduce vibrations which are the leading
Modular System with minimal site requirements
The CarnotJet System eliminates the need for chillers, air handlers, raised floors, and even aisle containment. The complete cooling infrastructure is integrated within the rack and pump modules. This integrated design helps grow infrastructure one rack at a time.
How It Works
The CarnotJet System has two major components:
The CarnotJet rack is essentially a standard rack tipped over its back and enclosed in a tank. Servers are lowered vertically into the liquid filled rack. Power Distribution Units (PDUs) can be mounted to the front or the back of the rack, while switches are mounted to the back.
The pump module contains coolant pumps, filters, and coolant-to-water heat exchangers. It is responsible for circulating the coolant between the racks and the heat exchangers. The hot coolant is removed from the racks, cooled through the heat exchangers and returned to the racks after filtration. By providing consistent and powerful coolant flow, the pump module promotes a stable and uniform cooling environment for the servers that is controlled to ±1° C throughout the Rack.
The pump module requires power connectivity and water connectivity from the facility. The pump module may be configured to use virtually any form of water available in a data center facility.
The ElectroSafe coolant is a non-toxic, clear, odorless, dielectric mineral oil blend. Dielectric oils have a history of being used in not just computing and electric power applications but in medical and domestic applications as well, making it extremely easy to handle and work with.
The high performance, low cost oil is readily available and is rated as 0-1-0 substance by the National Fire Prevention Association (NFPA), meaning that it poses no risk to human health, does not ignite readily, and can be treated with any fire suppression substance, including water.
