CleanAIR Systems, the first emissions control manufacturer to develop a compact
Tier 4 retrofit product for large diesel and natural gas engines, is pleased to
announce the recent installation and commissioning of six E-PODs at a secure
east coast data center.
The patent-pending E-POD is an
all-in-one emissions control unit utilizing selective catalytic reduction (SCR)
coupled with DOCs or DPFs. The product features internal mixing and proprietary
closed-loop technology housed within a critical grade, stainless steel silencer
shell. Using CleanAIR’s non-toxic, iron zeolite-based SCR catalysts, the E-POD
offers reductions of NOx, PM, HC and CO.
Working closely with Caterpillar
dealer Alban Engine Power Systems of Elkridge, Maryland, CleanAIR Systems
designed and manufactured a sophisticated emissions control system incorporating
the E-POD and a unique urea delivery system, retrofitted on six diesel 3516C CAT
engines rated at 2.5 MW each.
The engines, provided by Alban, were
required to meet Virginia DEQ air quality regulations and EPA Tier 4 Interim
levels. By installing CleanAIR E-PODs on each of the engines, NOx emissions were
reduced by 95%, with CO and HC levels dropping by greater than 90%. The
dramatically lower emission levels brings the data center into compliance with
air quality regulations and allows for extended engine run times.
To meet tight deadlines, a joint
effort between Alban and CleanAIR enabled the companies to produce, deliver and
install the systems within a short, three-month time period, making it necessary
for CleanAIR to build and ship all units within six weeks. The end-user’s
compressed project deadline, coupled with existing space restrictions,
necessitated that the E-PODs be installed early in the building process, prior
to engine installation and completion of the structure. The units were top
mounted, allowing the Caterpillar engines to slide in place below each E-POD. By
mid-January, the E-PODs were commissioned and operating.
The CleanAIR E-POD was specifically
chosen by the end-user, a prominent global IT infrastructure provider, for the
following reasons:
- the E-POD enabled their engines to
meet strict Tier 4 Interim requirements and regional
regulations
- the E-POD can be upgraded in the
future to meet Tier 4 Final requirements
- the system offers true closed-loop
controls with exact pre- and post-NOx measuring to regulate urea consumption and
decrease ammonia slip to extremely low levels
- the E-POD’s compact design is the
only emissions control product on the market capable of fitting within building
space constraints
Testing during commissioning of the
CleanAIR E-POD technology shows 95 to 97 percent reduction of NOx emissions in
closed-loop operation across all operating loads.
