Rack Mounted Low Delta-T Server Emulators

Rack-mounted server emulators are the perfect solution when you need to emulate the environmental conditions of a functional data centre with server racks already installed prior to testing.

A range of rack-mounted server emulator power loads are available 2kW and 3.5kW.

If you need to emulate the heat conditions of a data centre full of servers and there are no server racks in place, you should use either stackable server emulators or temporary server emulator racks, depending on your contract requirements.
