PEACE OF MIND

Since we started using iSilo 3D, we no longer have to estimate how full our silos are. We can see it in 3D at any time. This gives us more planning security and peace of mind.

SEE MORE, DECIDE BETTER

Your one-stop-shop for silo inventory

Accurate 3D bulk material inventory in real-time

Eliminate delayed or inaccurate inventory informations and make better informed decisions.

Buffer zone warning & feeder control

At all times, your PLC and SCADA system has correct detailed inventory information, incl. warnings and alarms.

Avoid discharge feed variation

Define individual material zones. Monitor your draw- and feed-points.

Material behavior monitoring

You will be surprised how your material behaves in the silo. Witness ratholes and dump cones forming, material caking on silo walls, …

Trusted Measurement, Reporting and Historical Analysis

Play it safe: Receive reliable measurements directly from our tamper-proof solution sent to your business tools. These are generally accepted by auditors as the results are accurate and do not rely on any person taking the measurement.

SEE HOW EASY IT IS, TO GET A PERFECT OVERVIEW

EASY TO INSTALL, SIMPLE TO USE, RELIABLE

Full visibility of inventory

iSilo 3D starts with robust radar sensors that scan the pile continuously and send the data over Ethernet to our powerful processing unit. The processing unit analyzes the data and sends all outputs directly to your PLC / SCADA systems over the interface of your choice. You can also use a web browser to access a user-friendly interface that provides a real-time, 3D visualization of the material as well as data storage and replay.

iSDR-P

3D Radar Sensor

The indurad Scanning Dynamic Radar – Premium (iSDR-P) is a 3D scanning radar with a field of view of 180˚x120˚ and a Millimeter resolution. The radar sensor covers the entire silo surface, both at low and high silo levels, at distances of up to 40 meters. The main housing parts are milled out of an aluminum block and are eloxated – no compromises are made on durability and longevity. The radar radome is milled out of a special teflon. The housing is IP66 rated / Nema 4x and corrosion resistant. Explosion proof ratings for Zone 20, 21, 22 according to IECEx / ATEX are available for selected sensor models.

The sensor runs on 12-36 volts and is connected via Ethernet to our processing unit (iRPU-F).

iRPU-F

Radar Data Processing Unit

The indurad Radar Processing Unit – Field (iRPU-F) is a compact cabinet which receives data from iSDR sensors via Ethernet and processes all data locally. The cabinet houses a powerful microprocessor, power supply, heater and can be supplied with several interface options (Socket TCP/IP, Ethernet/IP, ProfiNet, OPC, Profibus DP, RS485, RS 422, RS 232, CAN, DeviceNet, Digital I/O, 4..20mA, etc.). Optionally, a Fiber Optic port and remote access via WiFi and/or 4G/5G modem is available. The cabinet is rated IP65 for outdoor use between -20˚C and +50˚C. Optionally available for higher and lower temperatures.

FEWER MALFUNCTIONS, LESS MAINTENANCE

FEWER MALFUNCTIONS, LESS MAINTENANCE

Radar sensors outperform ultrasonic, lasers, 1D radar sensors, cameras and human eyes in harsh environmental conditions.
With inventions and innovations, we make a difference.

1D radar sensor often provide little data to deliver an appropriate picture of the stored materials. Besides this, they face issues with multipath propagation in narrow vessels and at steel support beams.


Laser-based solutions are known to deliver accurate results, but often suffer from malfunctions in dusty environments & are naturally maintenance-intensive.


Ultrasonic measurements are frequently distorted by bulk handling particles, drive noise, dust clouds & temperature or pressure fluctuations.

Fast and easy installation

The compact iSilo solution, consisting of a single scanning 3D radar (iSDR-P) and a combined processing and connectivity unit (iRPU-F), provides a complete surface model of the silo.
By knowing the capacity and deriving the current fill level, loading, unloading and truck dispatch times are significantly improved. The result is significantly reduced cueing times and more customer deliveries per day. One factor in particular improves the overall dispatch process, as a loading truck no longer has to wait for an unloading truck to finish its work. The system now allows the silo to be loaded and unloaded simultaneously.

Inventory information Safety

Aluminum Plant

Inventory information & Safety

The customer is an aluminium plant in Iceland. The material (alumina) they receive to feed the operation must be dispatched well in advance as it is delivered by vessels from distant suppliers around the globe.
The alumina is received into a large silo from which it is drawn into operation.To maximise production, it is vital to ensure the silo is close to empty when a ship arrives so that the maximum-sized shipment can be received without halting production.To achieve this, precise knowledge of the volume of material in the silos is critical to make the optimal dispatching decisions in a long lead-time environment.
The customer also encountered operational challenges during vessel unloading due to the inability to adjust the silo’s 17 filling points individually, which resulted in uneven material distribution during loading. To address this, operators were only able to slow the loading process to allow the material to redistribute more evenly. By observing this process during the ship unloading, the operators were able to adjust the filling points to achieve a more uniform distribution, ultimately leading to a reduction in unplanned and costly berthing times for the customer.

Clinker Silo Greece

Cement plant

Clinker Silo Greece

At our customer’s cement plant in Greece, knowing the exact fill level 24/7 is key to enabling the plant manager to make the right decisions. The clinker silo acts as a storage and buffer area between the kiln and the mill.
Knowing the free capacity as well as the remaining stock is therefore important for the smooth management of upstream and downstream production. With the indurad iSilo solution, the customer has this information available at all times. In addition, the current dead stock in the silo is finally visible and can be taken into account to calculate the current available capacity and to take corrective measures such as wall cleaning. The indurad radar solution can scan where other technologies fail: high temperatures above 100°C, dusty environments and moisture from the material. The sensor does not require regular cleaning or recalibration.
