Access Gantry


Our portable gantry can be adjusted to suit the diameter of the spray dryer. It is an adjustable length of 1.5m - 14m and we have one technician situated at each end of the gantry, working at 180 degrees at a time to ensure an efficient test. 


The gantry is tested annually and is constantly verified by trained technicians. Its lightweight aluminum design provides quick assembly and easy entry into the vessel, with a robust and strong construction (capable to support 475kg).

  • A complete spray dryer test including repairs can be carried out within 24/48 hours, ensuring that your downtime is minimised and you are quickly back into production.*

  • The technicians move the scanners across the vessel surface, the system signals the presence of a defect with an audible and visual signal on the control device, allowing us to pinpoint the defect. Said defect is then marked and given a location from a given datum ready for repair.


  • During a test, the technician scans 100% of the test surface, so overlapping of the controlled areas is ensured.


  • Multiple sensitivity settings of the Magnerscan scanner detect the different depths of defects.


  • Calibration is regularly checked against standard cracks in an approved stainless steel block having pre-defined cracks at varying depths.


  • We can provide fully qualified welders who will carry out repairs during the test duration or you may use your own on-site welders.

 *(extra time may be required dependant on repair work)


Our fully certified IRATA rope access specialists guarantee our team’s safety. Ropes allow flexible access and movement inside and around the vessels, ensuring your equipment is fully inspected and repaired.

Inspecting and repairing complex vessels is no longer a time-consuming challenge, when combining our testing technology with our rope access specialists. Using our rope access specialists, we can safely lower our technicians into tanks.


We can also safely inspect the shafts and other difficult-to-access areas of tanks without the requirement of ladders/scaffolding.


Ensuring that safety is never compromised, our clients’ needs for fast and clean inspections can now be achieved in a variety of vessels such as;


Cyclones, Bag Filters, Process Tanks, Fluid Beds, Air Heaters, and Cheese Vats/Tables


A cost-effective solution for long term spray dryer crack testing is to purchase our bespoke gantry and store or ship it between your factories. Our technicians then travel directly to your site(s) to perform the inspections.


Many of our regular clients are now doing this and seeing cost savings in transportation and time. If you are also interested, enquire now for a quotation & an estimated breakeven timeline.
