Grexen's Robotic Duct Cleaning technology 

in action

Robotic duct cleaning is the biggest technological advancement in our industry in over 50 years. Grexen was the first company in the US to invest in its promise, and for good reason. As the construction of building's become larger and large the more challenging it becomes to remove grease condensation from kitchen exhaust systems. Above is a duct in a popular shopping mall which posed a major fire risk.

Grexen's robotic duct cleaning technology, imported from Europe, restored over 75ft of 20 year old carbonized grease to bare metal in under 3 days.

ROOFTOP GREASE MANAGEMENT

PROGRAM

IMG_2629.JPG

THE PROBLEM

In most cases the Grease containment unit is too small as is the case in the above photo. In this example the unit has fallen off and is too small to hold the grease this system produces causing a grease spill covering a 100 sq. ft area

THE SOLUTION:

ROOFTOP GREASE MANAGEMENT PROGRAM
  1. A large volume unit is installed 

  2. A highly absorbent grease-only pillow is installed

  3. Monthly monitoring and pillow replacement ensures that grease never gets out of control.

ROOFTOP GREASE MANAGEMENT PROGRAM EXPLAINED

A Grease Containment unit is your first line of defense in capturing and holding grease that accumulates in the fan. The problem… as is the case of any container, is that they overflow when they get too full. Whats worse is that they are out of site so you don’t know you have a problem until it’s too late. 

 

Grexen’s monthly rooftop management program ensures that this never happens to you. By enrolling in Grexen’s monthly rooftop management program we install an appropriately sized unit in combination with our cutting edge grease absorption pillows and inspect the system monthly to ensure that everything is performing as it should. 

Our pillows are:

  • made from recycled hydrophobic materials absorbing 10 times its weight

  • 100% biodegradable grease neutralizers render the grease harmless

  • Only grease is absorbed, allowing water to pass through while keeping your roof uncontaminated.

 

Each month, before the pillow becomes over-saturated and overflows, Grexen removes the  saturated pillow, empties grease-waste and replaces a fresh absorption pillow ensuring that your roof is grease-free leaving your roof protected from the harmful exposure of grease fatty acids

 

Monthly Service fee includes:

  • Grease Containment Unit (Sized to your volume)

  • Monthly Hydrophobic  Pillow Replacement

  • Roof cleanup if needed 

  • Grease neutralizer application

  • Excl. initial roof restoration, and applicable sales tax
