Remote-Controlled Robots for Hazardous Operations
|
|
Arrow Ecology designs, builds and operates a unique robotic machine which
removes sludge and sediments from closed, complex industrial structures as
cooling towers, holding pools, lagoons, tanks and water bodies.
The accumulation of sludge or sediments in these facilities reduces
operational efficiency and frequently contains toxic compounds.
Handling these hazardous materials in structures like cooling towers or
storage tanks imposes serious safety and long-term health risks to workers.
The costs of “shut-down” time required for sludge removal and/or storage in
tank or lagoon farms where land values are at a premium add to the problem.

With Arrow Ecology’s unique, remote controlled “Sludge-Eater”
the operator can work a safe distance from the actual structures
from which he must dredge and/or pump sludge.
Thanks to its hydraulic controls the unit can operate fully
submerged underwater or inside flammable/explosive atmospheres.
This allows Arrow Ecology to remove sludge from petrochemical plants,
cooling towers and oil separators as they operate.
The robot is equipped with devices which enable it to work in almost
any space eliminating the cost of maintenance shut-downs.
The unit is rigidly built to provide powerful operation under harsh conditions.
Unique non-electric proximity sensors help the robot navigate around support columns
and other architectural features even when the operator is unable to see it.
The special propulsion unit and powerful sludge pump adapt to variations in viscosity
and insure speedy, efficient and safe completion of the task.

Dredging, jetting and cleaning equipment can be attached to accomplish
all necessary maintenance in one operation.

|
|
|
|
Main features:
|
|
Flow:
|
|
|
|
Up to 60-80 m3/hour of sludge by mouno positive displacement pump.
|
|
|
|
Dimensions:
|
|
The units are tailor-made and produced in sizes and configurations
dictated by the application.
The basic unit can be disassembled quickly for transportation or
for entering the robot through a 18” manhole in a tank.
|
|
|
|
Propulsion:
|
|
The unit is propelled by an external hydraulic power pack
which delivers propulsion power to the robot’s engine and pump.
The unit has a 1 ton load capacity.
|

Controls:
|
|
On-line wired or wireless remote control.
|
|
