Powder and Granular Materials
The control system is a vital part of any bulk material handling application. With many years of industry
experience, Nol-Tec is unmatched in its ability to provide the best bulk material handling and batch process
control systems in the industry. Our sales engineers work closely with you to completely understand your
specific requirements. Nol-Tec's engineers have years of experience successfully creating control systems
for complex bulk material handling, weighing, and batching processes.
|
User Friendly Operator Interface
Nol-Tec's HMI systems utilize graphic imaging to create screens that closely
resemble actual processes and equipment in your plant, thus increasing operator
awareness and efficiency.
|
Bulk Material Storage and Unloading
Nol-Tec has experience controlling a variety of convey equipment for bag, bulk bag, truck and railcar unloading,
with transfer to silos, bins, and weigh hoppers. This includes controls for various bin dischargers, convey line
switches and diverters, point and continuous level sensing, and dust collection.
|
Silo Level Inventory
One of the more challenging tasks is monitoring actual material levels in silos and bins. There are a number
of continuous level indicators on the market that work with varying degrees of success depending on material bulk
densities, dusting conditions, temperature, etc. In some cases, tank-mounted load cells are the best option.
Our engineers have the experience to recommend and integrate the best solution for a specific application.
|
Dense Phase Pneumatic Conveying
Our knowledge and experience with all types of dense phase conveying (purge systems, full line concept, dense
phase vacuum, continuous) give us the ability to provide controls for new or expanded systems. We also have
extensive experience retrofitting existing dense phase system controls.
|
Dilute Phase Pneumatic Conveying
Nol-Tec engineers have experience designing control systems for the various types of dilute phase conveying…
pressure or vacuum along with associated equipment and devices.
|
Blending
Powder materials can be efficiently and accurately blended utilizing compressed air. Nol-Tec engineers are
experts with many years experience in air blending.
|
Weighing & Batching
Many processes require that precise quantities of various ingredients be brought together to make up a specific
batch or formula. This typically involves metering materials individually into a weigh hopper using a device such
as a screw feeder, airlock, or butterfly valve. Nol-Tec's PLC based weighing systems combine years of experience
with our standard features such as fast/dribble speed, automatic preact, jog, tolerance alarms and state-of-the-art
data collection and reporting.
|
Metered Delivery and Injection
Nol-Tec Southeast is an experienced supplier of metered dry sorbent delivery and injection systems for emissions
control. These PLC and HMI based systems include continuous loss-in-weight feeders, pneumatic conveying and injector
controls. Read On>>
