Selective Catalytic Reduction
(SCR) (Euro built machines only)
Introduction
Selective Catalytic Reduction is an emissions
technology designed to help bring diesel machine
engines into compliance with new EPA regulations.
AdBlue® / DEF, a water solution of urea, is injected
into the exhaust stream to convert nitrogen oxide
(NOx) into harmless nitrogen and water vapour.
SCR is a straightforward NOx after treatment
system with the following advantages:
• Very little maintenance required.
• Reliable, proven approach. SCR is already pro-
veninhighvolumevehicleproduction.
SCR System
The BELL SCR system consists of an AdBlue® /
DEF tank, injector, sensors and wiring harness, and
a catalyst. The system operates automatically—all
the driver has to do is monitor an indicator on the
dash and top up the AdBlue® / DEF tank when
necessary. Warnings for low AdBlue® / DEF levels
similar to those for other fluids, like diesel, are
included, and must be adhered to, to prevent
engine power de-rating.
The range of the AdBlue® / DEF tank depends
upon the job the machine is doing, but should be
around 1:2 = One tank of AdBlue® / DEF, to two
tanks of diesel.
BELL machines fitted with the SCR system, require
no change to service and maintenance intervals. A
small AdBlue® / DEF filter on the pump module can
be changed in minutes. No catalyst maintenance is
required.
AdBlue® / DEF Storage
AdBlue® / DEF is nontoxic, nonhazardous and
nonflammable. It is non-polluting and meets strict
international standards for purity and composition.
AdBlue® / DEF poses no serious risk to drivers or
equipment when handled properly.
AdBlue® / DEF degrades over time depending on
temperature and exposure to sunlight. If stored at
recommended temperatures (not exceeding 25°C)
shelf life will be two years.
AdBlue® / DEF is available throughout Europe at all
major truck stops, dealers and distributors.
AdBlue® / DEF is packaged as follows:
• Retail Outlets (Stations)
• Home Depot ( > 3000L)
• IBC’s (Intermediate Bulk Containers) (1000L)
• Drum’s (208L)
• Cans (5L / 10L / 18L)
