With years of experience in the specialist field of cleaning silos, NQIS has cleaned silos, bins and hoppers of varying capacities all over the world.
Depending on the reasons for the vessel to be cleaned, is dependent on the cleaning method to be used.
Whether it's for maintenance purposes, blockages, not running at full capacity or even for the removal of redundant material, using either NQIS's Vacuum Tankers or our Gyro Whip System - and when necessary both, will restore your vessel back to optimum running capacity.
Vacuum Tankers are predominantly used to empty silos. Once extracted, they can dispose of the product in a variety of methods: tank to tank transfer or simply tipping. Our Vacuum Tankers can also return the product back to the system using their high-pressure blowers. These high-pressure blowers operate at 3 times the speed of normal blowing units, thus speeding up the process of getting the silo back on-line.
If viable, re-introducing the product back to the system can potentially save thousands of pounds from having to re-mill or simply tipping the product away. This environmentally friendly option also helps reduce dust emissions.
The Gyro Whip is used when blockages ,build-ups & 'rat-holes' occur. This method offers a safe and fast solution to maintaining clean and continuous operating conditions in silos, bins & hoppers.
Being a wholly remote system, there is no need for dangerous, time consuming man entry operations that could potentially put employees in close proximity to hazardous, unstable blockages and hang-ups.
The air-driven spinning chains of the Gyro Whip knock down the product from the walls of the vessel, enabling it to be run off onto a belt or extracted by means of Vacuum Tanker.
The whip's spinning chains can be made from steel, brass or nylon, depending on the environment and conditions it is operating in. Making it suitable for use in potentially explosive environments.
