Fuel Polisher (M3 Series):

Fuel Polishing is an advanced multi-stage form of filtration critical for generators to start and run reliably.  As diesel fuel ages, particulates form which can increase the wear on generator engine parts, block filters, and corrodes tanks. Fuel tanks accumulate water through condensation encouraging bacterial growth. Diesel engine emissions technology requires higher purity fuel to prolong engine life. This is essentially an Automatic Fuel Oil Maintenance System which continuously maintains your fuel source via a scheduled removal of water and particulate from your tank.

 

We offer both portable and stationary designs for a wide spectrum of industries. Their automatic mechanical processes was created to successfully clean sludge, water, microbial contaminants, and other sediments found in a variety of diesel fuel, biodiesel, hydraulic fluid, and light oils being stored in above or below ground tanks. Most models are designed for direct integration into most standard brand factory supplied generator control and monitoring systems and utilizes Racor replaceable filters.  These are available as indoor packages or mounted within stainless steel outdoor enclosures.

                          

DEF Urea Tanks & Pumping Systems for Generator SCR emission control:

Integrated Systems for Generator Diesel Exhaust Fluid (DEF) Urea.  Includes Stainless Insulated Tanks, DEF Tank Fill Systems, DEF Urea Pumps and Filters, DEF Urea Heating and Cooling Systems. DEF requires specialized storage to maintain required quality for generator exhaust treatment.  DEF is a highly pure chemical fluid and must be stored in a specially designed tank to maintained closely to its 32.5% concentration of urea in 67.5% de-ionized water.  Most diesel engines with Selective Catalytic Reduction (SCR) emission systems are specifically programmed for optimal performance at this ratio.  DEF fluid is in used to reduce the NOx pollutants, in exhaust gases. DEF must be protected both from low temperature freezing (12ºF) and high temperature degradation.  The quality is critical since many diesel generators cannot legally be operated without effective in specification pollution control.

 

DEF Urea Head Tanks:

They typically mount on the wall or on a stand within the enclosure and refill the standard DEF tank on the generator engine by gravity flow.

 

DEF Urea Storage Tanks:

The DEF Urea Day Tanks provide safe storage of DEF Urea for generator SCR emission controls. The cubic design saves space in crowded generator rooms or enclosures.  The UM5 is available as single wall, double wall, or double wall insulated in stainless steel, HDPE inner with stainless steel outer shell, or HDPE plastic.  This can be customized for the application with instrumentation, heaters, and pumps. Controls interface with generator systems with High, Low, Leak contacts or optional Modbus / BACnet connectivity. 

 

           

 

Caterpillar DEF Urea Buffer Tank Refill Interface

The UM5BTI Cat DEF Urea Buffer Tank Refill Interface provides automatic refilling for Caterpillar SCR DEF Urea Buffer Tanks from remote bulk storage tanks and pumps.  The unit is installed adjacent to the the buffer tank to provide the required low pressure feed to the buffer tank. Controls interface with generator systems with High, Low, Leak contacts or optional Modbus / BACnet connectivity.

 

 

Air-Assisted Compressor Packages for SCR Systems:
Some engine manufacturers require specific models to utilize air-assisted DEF urea injection in their SCR systems.  These are typically on large engines in which the large size of the exhaust duct requires an expanded yet uniform mix of DEF urea and the exhaust gases.  This system adds compressed air to the DEF urea injector to enhance the atomization of the urea fluid and theoretically should reduce the combination of fuel and DEF Urea consumption. Earthsafe is supplying these systems.

                       

 

Day Tanks and Refill Controls (M5 Series):

Earthsafe has provided thousands of day tanks worldwide, all with their modern and reliable  integrated network ready control panels for today's building systems.  As generator sub-base tanks have replaced day tanks in many applications, Earthsafe has adapted its refill systems to the special challenges of the application.  Day Tanks are available in a full range of sizes 25-2,500 gallons as double wall, 150% or 200% Rupture Basin, standard UL 142 or fire-rated UL 2085 units.  The complete package is quoted with all the accessories you want and require.

Fuel Header Tank System:

Earthsafe manufactures complete packaged Fuel Header Systems for Generators in Buildings or Rooftops with limitations for fuel storage. The header is fed with fuel from bulk storage tank using a duplex pump system. The flow is initiated and continues through the generator run event. Excess fuel overflows from the header back to the storage tank. Where required, an ON‐OFF refill is available with a duplex overflow pump / reservoir where fuel storage is above-ground tanks above the header level.  This is an ASME Code Vessel. 

 

A fuel header system is designed to provide fuel to multiple generators, where there are severe regulatory restrictions to the volume of fuel that can be stored in the generator room. The header is typically up to 330 gallons and 8” to 24” diameter pipe which runs 10' to 20' long or the length of the room to serve all the generators. The pipe is sized to be less than the regulatory limit for fuel storage quantities in the room.

 

The generators draw fuel from the header pipe, and return fuel to the header pipe. The fuel supply pumps draw fuel from a bulk tank and pump to the header inlet. The header outlet is a gravity overflow back to the bulk storage tank.

 

Redundant Master Controllers interface with the facility PMS, (Power Management System), to allow the operators to have comprehensive monitoring of the fuel system.  Fuel fill stations, fuel filtration polishers, and duplex fuel transfer pumps are available.

 

The M5H model below is a compact packaged design for an individual generator set and can be placed within an enclosure.
