DEF for Generators Top 10 Questions

05-22-2020

What is DEF?

Diesel Exhaust Fluid (DEF) is a mixture of Urea in Deionized water in a 32.5 % concentration. It is used as a consumable fluid in diesel engine emissions control using Selective Catalytic Reduction (SCR).

How Much DEF do I Need?

A good rule of thumb for generators is that DEF consumption will be about 10% of diesel consumption. Tanks can be sized at 10% of the fuel storage requirements. Pump and pipe systems for replenishment can be sized as well for about 10% of the diesel systems.

End-of-Life PLC Upgrades for Allen Bradley and Siemens

End of Life for Micrologix 1000/1500:

There are several million Micrologix 1000 PLCs in service around the world, including thousands in critical service in data center equipment. Hundreds of Dot‐Com Era (1998 – 2002) data centers are still in service throughout the US and world.

Many of these facilities are very valuable because they occupy locations close to large cities and fiber optic infrastructure.  Earthsafe built fuel systems for many of these facilities, and our systems have operated reliably over that time with very little maintenance.

Clean Diesel Rules for Generators: NFPA 110 Drilldown

Clean Fuel for Generators: Drilldown of NFPA 110 Rules

For those of you who just don’t like to read, or have only a moderate tolerance for reading codes and regulations, we have the done the dirty work for you. 

NFPA 110 “Standard for Emergency and Standby Power Systems” is the standard for people who own and operate buildings with emergency generators.  It’s the starting point of what a building owner should consider as good practice, and may go further toward a legal requirement since it is referenced in building codes.

Why You Should Worry about your Generators Old Diesel Fuel

07-05-2018

Diesel Fuel Gets Old Fast – 3 Months

Not like your car, fuel sits in a generator tank for a long time, because it is stored for when you need it.  Say you have a 300 KW generator and you want 8 hours of run time.  At full load you need 20 gallons per hour so you need a 160 gallon tank.  If you test your generator once a month for 15 minutes unloaded, you will use 7 gallons per hour 3 hours per year for a total of 21 gallons per year.  That means, without a big power outage, you would use all your fuel in about 8 years.

DEF System Design for Caterpillar Generators

DEF System Design for Caterpillar Generators

Earthsafe has developed a Flow Control Unit specifically for Caterpillar SCR Emissions System.  The CAT System has a DEF Urea Dosing Unit with buffer tank that requires a 5 – 10 PSI inlet feed of DEF with overpressure protection at 10 PSI.  This can be a tough requirement if the DEF storage tank is remote or there are multiple generators being fed DEF from a single bulk tank.

Think 10% for Generator DEF Tank Sizing

Think 10% for DEF Tank Sizing

A good rule of thumb is that DEF consumption is about 10% of fuel consumption.  So size DEF day tanks and bulk tanks at about 10% of fuel storage tanks.

Our new DEF Tanks are cubic stainless steel tanks 25 – 2500 Gallons. They are designed for use in the harsh operating environment of diesel power generators to provide reliable supply to emissions SCR units. They are available as single wall, double wall, with optional insulation. .

10 Second Start for Life Safety Gensets

01-16-2017

Earthsafe fuel systems are modular and network ready.  So they lend themselves to applications in tall buildings where even life safety generators have some complexity.  Fill stations may be at grade, small bulk tanks in lower levels, and generators on the building roof.

“Reliable Generator Start and Run” is the basis for our fuel system designs.  We recently came across a Cummins Power publication that explains the 10 Second Start and other important aspects of NFPA 110 Standard for Emergency and Standby Power Generators.

Tall Building Fuel Systems: Potential for Catastrophic Exposure

01-16-2017

Electrical loads in critical building systems have grown tremendously, sometimes by as much as 400% versus comparable older buildings.  With larger power loads comes the need for larger volumes of fuel storage for emergency generators.

Earthsafe fuel systems are modular and network ready.  So they lend themselves to applications in tall buildings where even life safety generators have some complexity.  Fill stations may be at grade, small bulk tanks in lower levels, and generators on the building roof.

Getting Juno to Jupiter with Earthsafe

08-14-2016

“What do you do Here” is a question we always ask, being naturally curious engineers.  Sometimes we get interesting answers.  We recently completed a new fuel system for a data center upgrade in Colorado.  The answer we got was that amongst other things “We are sending a spacecraft to Jupiter – it just arrived”

Here is a link to the local news story:

New Urban Multi-Use Development Projects

08-14-2016

Earthsafe recently completed Urban Multi-Use Development Fuel System projects.  The challenge of these projects are the number of dispersed and independent fuel systems for generator service.  A hotel in the development will have separate needs from a commercial office tower.  A residential tower and Retail Area / Malls) will have different needs as well.  All of the fuel systems need to fit in within a complex building environment that includes extensive parking and pedestrian areas.

New UPS for Fuel System Control Power

06-14-2016

The new C6-UPS01 Control Power UPS is designed to provide a battery backup Uninterruptible Power Supply (UPS) for fuel system controllers and tank monitors such as Veeder Root, Pneumercator, and Franklin-Incon.

The C6-UPS01 provides a 120-230 VAC power source for 500VA to operate a small controller for 2 – 8 hours with expandable battery packs.

Fuel System Master Dual Power Source

06-14-2016

The new C6-ATS(PDU) provides dual source power for the full fuel system including all pumps and controls.  The Automatic Transfer Switch (ATS) monitors incoming power source quality and automatically switches to the secondary source, upon failure of the primary.

The C6 panel is also a Power Distribution Unit (PDU) providing branch circuit breakers with monitoring contacts for each individual pump and controller in the system.
