Our experience in a broad spectrum of applications
and industries, combined with a comprehensive range of services, allows us to maintain
total engineering and design capabilities. Our goal is to improve our
customers' productivity, quality, safety and profits by improving or
expanding upon their facilities, processes and control systems.
We offer consulting services to assist our clients in
developing their projects. These services consist of developing basic
plans, such as, an automation assessment, safety assessment or basic project
evaluation. From there we can assist in developing the ideas into detail plans and capital budgets.
We recommend following our
four step process.
Profiles of our Services:
Project Profiles:
-
Arch Chemicals, Inc. - Power
Systems Evaluation [PDF]
- Extensive field survey of the plant's transformers,
feeder cables, power switchgear, large motors, protective relays and circuit
breakers. Analyze all distribution systems (69kv through 480v) to determine
the capacity of over-current protective equipment to safely open circuits under
fault conditions. Develop coordination curves and analyze parallel feeders.
- Louisville
Water Company - Control System Upgrade
[PDF]
- Upgrade and replacement all of the process control systems used to
operate Louisville Water Company's two water treatment plants, two
principal pump stations and twenty one distributed water pumping
stations. Changes in demographics in Jefferson County and the
surrounding area over the last decade necessitated that the new system
not only solve existing problems but also provide for ease of future
expansion.
-
Rohm
& Haas, Inc. - Ongoing, Full-Service Engineering [PDF]
-
Rohm & Haas has retained the services of Pfeiffer Engineering
continuously since 1984. Over 875 projects have been completed at their
Louisville facility. Other locations include West Alexandria and
Cincinnati, Ohio. Services include conceptual development, design,
software, construction coordination, startup assistance, and training.
-
Eckart America L.P. - Paste
Plant Automation Projects
[PDF]
- Design and installation of new process control and automation systems
for seven pigment paste manufacturing processes. Increase in demand for
higher quality products necessitated new and highly automated process
equipment to minimize operator intervention while yielding better
quality products with accurate tolerances.
-
Apollo America -
Lubricating Oil Blending Plant [PDF]
- The facility is a
highly automated blending plant that was built to supply automotive lubricants
and production lubricants for the automotive industries. This was a
design/build project that included process electrical and instrumentation
design, process design support and development of P&I diagram. We also
provided the process control system, all process control hardware, field
instrumentation and software.
-
Hillshire Farms - Refrigeration Control System [PDF]
- Revise the control system of a refrigerated finished
product warehouse, freezer and shipping dock. The PLC control logic was
modified to replace the existing manual temperature control with automatic
temperature control. The defrost controls were also revised and switched from
defrosting based upon a fixed time of day schedule per evaporator to defrost
after an accumulated run time. Electric power consumption information was
obtained from the utility’s meter and used as the basis for demand control.
-
Louisville Gas &
Electric Company - Coal Stack/Reclaim Electrical Renovation
[PDF]
- Design and installation of a new electrical distribution system,
drive systems, instrumentation and control system for the generation
station's 20 year old coal pile stacker/reclaim system. The system is a
self-propelled unit that distributes coal to a horizontal pile as an
intermediate storage system between barge/train unloading and the boiler
feed silos. The unit also reclaims the coal upon request.
-
Rohm & Haas, Inc. -
Power Distribution And Monitoring Upgrade
- Implementation of a plant wide
electrical power monitoring system for the medium and low voltage
distributions of a large industrial chemical plant. Monitor three-phase
voltage, current, kW, kVA, kVAR, kWh, kVAh, kVARh, power factor, and
frequency. Also, the monitors could perform power quality analysis by
determining the total harmonic distortion, individual harmonic levels, and
K-factor for all voltage and current inputs. The system was able to do
waveform capture for power quality and fault analysis. The status of the
substation and ground fault relays, and transformer temperature levels were
continuously monitored. Services included design, installation, programming,
checkout, and documentation of the system.
-
Big Rivers Electrical
Company - Flue Gas Desulphurization Control System Retrofit
[PDF]
- Complete redesign of
operator control station. Provide centralized alarming, data collection,
and a fully redundant control architecture. This system replaced
numerous discrete analog controls with centralized graphical
workstations.
