TEGRAS: Professional Technology for Complete Commercial Kitchen Exhaust Cleaning

Mechanical brushing, active foam, ultrasonic filter cleaning and inspection for hoods, plenums, grease ducts and exhaust fans.

Why commercial kitchen exhaust cleaning must go beyond the hood
A commercial kitchen exhaust system is much more than the visible stainless-steel hood. Grease-laden vapours pass through filters, plenums, horizontal and vertical ductwork, bends and exhaust fans. As a result, a hood can appear clean while significant grease remains hidden inside the extraction system.
TEGRAS by TEINNOVA is a professional technology line developed specifically for this challenge. Its equipment helps kitchen exhaust-cleaning contractors inspect, clean and verify the different parts of the system using mechanical brushing, active foam, controlled rinsing, ultrasonic cleaning and video inspection.
Mechanical brushing for grease ducts
Grease ducts often contain long sections that are difficult to reach manually. Mechanical brushing takes the cleaning action inside the duct, using rotating brushes selected according to duct dimensions, geometry and the type of contamination.
MULTIPRO is TEGRAS’s pneumatic brushing system for professional exhaust-duct cleaning. It offers a long working range and can be connected to a foam generator so that active foam is supplied through the same working hose before or during the brushing process. FORTE provides pneumatic brushing for larger exhaust ducts, while EON is an electric system designed for small and medium-sized ducts where an air compressor may not be practical. IBRUSH provides a compact electric solution for rooftops, terraces and other areas where portability is essential.
Active foam for hoods, plenums, fans and ducts
Grease removal often benefits from combining chemical and mechanical action. A dense active foam remains in contact with vertical and overhead surfaces longer than a simple liquid spray, helping soften grease before brushing or rinsing.
IFOAM PRO is the advanced TEGRAS foam-generation solution for cleaning hoods, plenums, ducts and exhaust fans. IFOAM COMPACT offers the same professional principle in a smaller portable format for locations where mobility and reduced footprint are important. Both systems are designed to generate controlled foam from water, air and cleaning product, allowing the technician to apply a consistent layer to contaminated surfaces.
When connected to a TEGRAS brushing system, foam can also support the mechanical cleaning of internal duct surfaces. This combination is particularly useful where grease is strongly attached and requires both contact time and mechanical action.
Ultrasonic filter cleaning with FILNET
Commercial kitchen filters contain internal channels and folds that can retain grease even when the exterior appears clean. FILNET uses ultrasonic cavitation to clean submerged filters and compatible kitchen components, allowing the cleaning action to reach areas that are difficult to access with external pressure alone.
The range includes FILNET B100 for lower-volume operations and FILNET B300 for contractors or facilities that need to process a larger number of filters in each cycle. Ultrasonic cleaning can reduce repetitive labour, standardize the cleaning process and help contractors develop filter cleaning as a professional service rather than a purely manual task.
Inspection and verification are part of the process
The internal condition of a grease duct cannot be evaluated reliably from the hood alone. Professional cleaning should therefore begin with inspection and end with verification. TEGRAS includes video-inspection solutions such as VISIOMAX, helping contractors assess contamination, identify access limitations and document before-and-after conditions.
Access panels, correct brush selection, containment of grease and wastewater, and final documentation are all essential to a complete service. The objective is not simply to operate a machine; it is to demonstrate which areas were treated and what result was achieved.
A business opportunity for specialized cleaning companies
Kitchen exhaust cleaning can be added by cleaning companies, fire-safety contractors, facility service providers and entrepreneurs looking for a more technical service line. Restaurants, hotels, hospitals, schools, industrial kitchens and catering operations all use extraction systems that require inspection and maintenance.
TEGRAS combines equipment with professional training and technical support. This is important because the profitability of the service depends not only on machine performance, but also on correct inspection, job pricing, technician productivity, recurring maintenance and the ability to document results for the customer.
Conclusion
TEGRAS provides a complete technological approach to commercial kitchen exhaust cleaning. MULTIPRO, FORTE, EON and IBRUSH address duct brushing; IFOAM PRO and IFOAM COMPACT provide active foam; FILNET cleans filters ultrasonically; and video-inspection equipment supports verification. Together, these technologies help professional contractors clean beyond the visible hood and treat the extraction system as the connected technical installation it really is.
