Fuel Header for Data Center Generators: Case Study



Challenged with a 16 generator plant for a large data center, an innovative fuel supply systems was designed.  A fuel header piped was installed to run the length of the generator room to provide generator connections. 

The fuel header pipe is reliably refilled by an outside fuel storage and transfer system.  Fuel fill stations, fuel filtration polishers, and duplex fuel transfer pumps

Best Practices for Hospital Fuel Oil Systems: Design Guide



Complex, Expensive, and Difficult to Commission might describe your experience with Hospital Fuel Oil Systems.  But a clean efficient design can help you minimize the pain.  

Earthsafe fuel transfer modules and controls fit together into a broad range of smart connected systems for Hospitals. Day Tanks, Filter-Polishers, Duplex Fuel Pumps, Fill Stations, and Master Fuel Controllers work together seamlessly.



UCSD Jacobs Hospital Fuel Oil System: Case Study



The UCSD Medical Center required a new Central Energy Plant to support the new 10 story 500,000 SF Jacobs Medical Center.  The central plant included 4 generators of 2 MW capacity located on an upper floor, and a set of boilers located on the lower floor. Fuel is stored in 2 underground storage tanks of 40,000 gallon capacity.


UCSF Mission Bay Hospital Fuel OIl System: Case Study



The UCSF Medical Center in the Mission Bay area of San Francisco required a new Central Energy Plant integral to the new 800,000 SF Hospital.  The central plant included 3 generators of 2 MW capacity located on the building roof, and a set of boilers located on the upper floor. Fuel is stored in 2 underground storage tanks of 40,000 gallon capacity.


Urban Hi-Rise Hospital Fuel Oil System: Case Study



The Lurie Childrens Hospital is the tallest childrens hospital in the world.  The building is 23 stories high and in total 1,255,000 SF.  The small footprint and high energy needs of the facility required a special fuel system design. The central plant included 5 generators of 2 MW capacity located at the lower level, and a set of boilers located on the 23rd level upper floor. Fuel is stored in 3 underground storage tanks of 40,000 gallon capacity.


Rush Medical Center Fuel Oil System Case Study



Rush University Medical Center in Chicago required a new Central Energy Plant to support its new 14 story 806,000 SF hospital.  The central plant is located in an urban area requiring the location of the bulk storage tanks within the lower level of the building protected within specially constructed rooms. The 6 generators and the boiler plant are located on upper floors and are fed by duplex pump sets at the lower level.


Modular System at HCA Data Center in Nashville


Modular System at HCA Data Center in Nashville

Earthsafe provided a modular fuel system for a new data center in Nashville for HCA. HCA is the largest private hospital network in the US>  The fuel transfer system was delivered in 2 prefabricated modules.  Module 1 receives fuel, performs rapid polishing and transfer fuel from a receiving tank to bulk storage.  Module 2 provides additional filter polishing and transfer fuel to the generator building.  The system supports 5 new E1 Dynamics Rotary UPS units.

HCA St. Lucie Medical Center

Earthsafe completed a new fuel system for the St. Lucie Medical Center in Florida.  The project continues Earthsafe service to HCA, the largest private hospital network in the US.  Last year Earthsafe completed a system at the new HCA data center near its headquarters in Nashville. 

The St. Lucie project was completed by Florida Metro Construction who has extensive experience with medical facilities throughout South Florida.



Kaiser Hospitals South Bay and San Rafael


Kaiser South Bay and Kaiser San Rafael.

Earthsafe continues its service to Kaiser Healthcare in California with new fuel systems at Kaiser South Bay and Kaiser San Rafael.  Kaiser is the largest managed healthcare group in the nation se3rving 9.3 million members through 37 medical centers. 

Earthsafe controllers are specifically approved by OSHPD for earthquake resistance, and have become the first choice for fuel system controls throughout California.

Earthsafe Supports Nuclear Weapon Compliance


Earthsafe supports Nuclear Weapon Compliance

Earthsafe recently completed the fuel system for the new AFTAC facility at Patrick AFB near Cocoa Beach, FL.  The AFTAC mission it is to detect and report technical data from foreign nuclear explosions. As such, AFTAC monitors signatory countries' compliance of nuclear treaties like the Limited Test Ban Treaty. 

The facility was designed by FLAD Architects and the general contractor was Hensel Phelps.

New Ft Benning Hospital Fuel System


Earthsafe recently completed the fuel system commissioning for the new central energy plant at the Ft. Benning Medical Center.  The new 745,000 SF facility is one of the largest hospitals built in the US in recent years.  It was delivered under a design – build type project system. 



5 Data Centers – 5 Months


Earthsafe recently completed shipments for 5 large data centers fast-tracked in a 5 month timeframe for a large internet services firm. The project included fuel systems for about 100 large generator sets exceeding 200 MW total capacity. The systems included 4 distinct design concepts: day tanks, base tanks, solo ASTs, and header systems. All were designed and executed with redundant mission-critical components. Earthsafe provided a full range of integrated components: day tanks, overflow tanks, duplex pump systems, fill stations and filtration polishers.


Belgium Data Centers

Earthsafe has recently completed several large data center fuel systems at a facility in Belgium. The projects were fast tracked for delivery to the client, presenting a challenging schedule as well as sequencing. An international team was involved in coordinating, building, testing, and commissioning the specialty systems. All of the systems were built to CE electrical standards and to conform with the Belgium electrical codes. Generators provided by Cummins Power System. Yes the image is diablo rouge – the team that defeated the US at the world cup.

Working in Belgium with International Team

Our recent projects in Belgium involved international teams of engineers, specialty systems suppliers, and craft labor. The site had over 1000 people working daily at peak, and these speaking 20 different languages. The level of workmanship, and also the work ethic was very impressive.
