What Is TEGRAS? TEINNOVA Technology for Professional Kitchen Exhaust System Cleaning

Professional equipment and methodology for cleaning hoods, plenums, grease ducts, filters and exhaust fans in commercial and industrial kitchens

TEGRAS is TEINNOVA’s technology line specialised in theprofessional cleaning of commercial and industrial kitchen exhaust systems.

Its purpose is to provide technical cleaning companies with the technology required to inspect, clean and verify the different areas that make up an exhaust system: hoods, filters, plenums, exhaust ducts and exhaust fans.

TEGRAS is part of TEINNOVA, a manufacturer specialised in technical cleaning technologies. TEINNOVA develops its solutions through three main areas: TECAI, specialised in HVAC and ventilation duct cleaning; TEGRAS, specialised in commercial kitchen exhaust systems; and ICS, focused on industrial cleaning solutions.

With more than 20 years of experience developing technical cleaning technology, TEINNOVA solutions are currently used in more than 100 countries.

What is a professional kitchen exhaust system?

A kitchen exhaust system is designed to capture and remove smoke, heat, vapours and airborne grease generated during cooking processes.

Although the hood is the most visible part, the complete system may include:

  • · Exhaust hoods
  • · Grease filters
  • · Plenums
  • · Horizontal ducts
  • · Vertical ducts
  • · Bends and transitions
  • · Access panels
  • · Exhaust fans
  • · Fan housings
  • · Discharge points

All these components are part of the same system.

Grease carried by the airflow does not accumulate only on the hood. Part of it passes through the filters and can gradually build up in plenums, ducts, bends and fans.

Por eso, That is why cleaning a hood is not the same as cleaning a complete kitchen exhaust system..

What is TEGRAS technology used for?

TEGRAS has been developed specifically to support the professional cleaning of the main critical areas of a kitchen exhaust system.

The technology covers three main applications:

1. Exhaust duct cleaning

MULTIPRO_products TEGRAS

MULTIPRO

EON

FORTE

IBRUSH

Exhaust ducts can accumulate grease on surfaces located several metres away from the access point.

To remove this contamination,professional mechanical brushing equipment is used to take the cleaning action directly inside the duct.

TEGRAS offers different brushing systems for different duct diameters, geometries and installation conditions.

The main systems include:

MULTIPRO, for example, is a pneumatic brushing system for grease ducts that can work up to 30 metres from a single access point and can combine brushing, foam application and rinsing.

EON provides an electric alternative for ducts up to 600 mm, while IBRUSH is a portable solution designed for locations where access is difficult, such as rooftops and technical areas.

Equipment selection depends on factors such as:

  • Duct diameter
  • Geometry
  • Length
  • Number of bends
  • Contamination level
  • Accessibility
  • Type of grease

The objective is to take the cleaning technology to the contaminated surface, even when that surface cannot be reached directly from the access opening.

2. Active foam cleaning for hoods, plenums and exhaust fans

The work surfaces in a professional kitchen present a different problem.

Hoods, plenums and exhaust fans may have grease on their surfaces:

  • Verticales
  • Horizontales
  • Steep
  • Uneven
  • Difficult to access

For these applications, TEGRAS uses professional active foam generators.

The main systems are:

Foam allows the degreasing product to remain in contact with the surface longer than a conventional liquid application.

This increases chemical contact time and makes grease easier to remove.

IFOAM PRO is designed for more demanding professional jobs and combines automatic foam generation with high-pressure rinsing.

IFOAM COMPACT offers the same professional foam concept in a more portable configuration.

The systems can be used on:

  • Hoods
  • Plenums
  • Exhaust fans
  • Greasy surfaces
  • Exhaust ducts

Foam can also be supplied to TEGRAS brushing equipment, allowing chemical and mechanical action to be combined directly inside the duct.

Why combine active foam and mechanical brushing?

Grease inside an exhaust system can become strongly attached to the duct surface.

For this reason, the TEGRAS method combines different cleaning principles.

First, active foam acts on the grease and helps soften it.

Then, mechanical brushing provides the physical action required to detach the contamination from the duct walls.

Finally, the system can be rinsed to remove the generated residues.

This combines:

  • Chemical action
  • Mechanical action
  • Contact time
  • Temperature
  • Controlled rinsing

This combination is one of the key principles of the TEGRAS Method.

3. Professional ultrasonic filter cleaning

FILNET B300

FILNET B100

Grease filters are the first barrier against contamination generated during cooking.

However, their internal geometry can make some areas difficult to clean using conventional methods.

TEGRAS offers the FILNET range, designed for professional ultrasonic filter cleaning.

The main models are:

FILNET B100 can process approximately four to five filters simultaneously, while FILNET B300 is designed for higher volumes and can clean approximately fourteen to fifteen filters per cycle.

Ultrasonic technology generates cavitation within the cleaning fluid, enabling it to act on:Canales interiores

  • Internal channels
  • Folds
  • Corners
  • Hard-to-reach areas

This makes it possible to automate and standardise a task that is carried out on a regular basis in professional kitchens.

The TEGRAS Method for kitchen exhaust system cleaning

TEGRAS should not be understood simply as a collection of independent machines.

The technology is designed around a complete kitchen exhaust cleaning methodology.

The TEGRAS Method is structured around five main stages.

1. Internal inspection

Before cleaning begins, the real condition of the exhaust system must be assessed.

Inspection helps to:

  • Identify grease accumulation
  • Assess internal duct condition
  • Locate critical areas
  • Detect insufficient access
  • Define the required cleaning method
  • Document the initial condition

Video inspection is especially important because most of the installation is hidden.

2. Active foam application

The degreasing product is applied as foam to contaminated surfaces.

The foam adheres to the surface and increases the time during which the product can act on the grease.

TEGRAS also offers COMEGRAS, an ultra-concentrated degreaser designed to work with IFOAM foam generators.

3. Mechanical duct cleaning

Brushing equipment introduces a rotating brush inside the duct.

This mechanical action works directly on the attached grease and can reach sections located far from the access point.

Brushing can also be combined with foam application.

4. Rinsing and residue removal

Once the grease has been detached, controlled rinsing removes:

  • Grease
  • Chemical product
  • Foam
  • Residues generated during brushing

Water and waste management are an essential part of a professional cleaning process.

5. Final inspection and verification

Una vez finalizado el trabajo, el interior del sistema debe volver a inspeccionarse.

After cleaning, the inside of the system should be inspected again.

Verification allows a comparison between:

before cleaning → after cleaning
Photos and videos provide the customer with objective evidence of the result.

Why internal visibility matters

One of the biggest challenges in duct cleaning is that the customer normally cannot see the work being carried out.

For this reason, inspection and documentation are part of the TEGRAS methodology.

Visualisation technology allows professionals to:

  • Inspect before cleaning
  • Monitor the cleaning process
  • Identify areas requiring additional passes
  • Take photographs
  • Record video
  • Verify the final result

Equipment such as MULTIPRO can incorporate VISIOPRO to view the inside of the duct in real time and capture images and video during the work.
Another of our video inspection systems is VISIOMAX.

This means the professional can not only clean the system, but also prove that the cleaning was carried out.
