(Redirected from EFI System partition) The EFI system partition (ESP) is a partition on a data storage device (usually a hard disk drive or solid-state drive) that is used by computers adhering to the Unified Extensible Firmware Interface (UEFI).
As much as 80 to 90% of the electrical energy used by an air compressor is converted to heat. A properly designed heat recovery unit can recover 50 to 90% of this heat for heating air or water.
1 A 5 HP reciprocating industrial air compressor might cost approximately $1,000 to $2,500; while a 5 HP rotary air compressor costs roughly $2,500 to $5,000.2  The cost for a 10 HP air compressor is approximately $3,500 to $7,000. A 25 HP reciprocating industrial air compressor costs around $8,000 to $12,000, while a 25 HP rotary air compressor costs around $7,500 to $10,000. 2  A 50 HP rotary air compressor might cost around $12,000 to $18,000 or more. 3  A 100 HP industrial air compressor costs roughly $20,000 to $35,000.
