Continental Hospital
A commercial kitchen exhaust system is a continuous pathway designed to clear out smoke, intense heat, and vaporized oil. If neglected, these vapors cool down and solidify into a thick, highly flammable layer of black grease inside the exhaust lines.
Our specialized cleaning service targets the three core zones of the pipeline system:
Kitchen Hood & Baffle Filters: Deep chemical soaking, carbon removal, and high-pressure washing of stainless-steel hoods to restore original shine and cleanliness.
Exhaust Duct Pipeline Degreasing: Accessing horizontal and vertical duct pipelines by installing custom, leak-proof access doors where necessary. Technicians remove heavy sludge using industrial scraping tools and food-grade chemical degreasers.
Centrifugal Exhaust Fan & Blower Service: Thoroughly cleaning the exhaust fan blades and housing. Removing accumulated grease restores aerodynamic balance, eliminates heavy motor vibrations, boosts suction power, and cuts down energy bills.
Because every commercial kitchen layout in Bangladesh varies significantly—ranging from compact restaurant setups to massive, complex institutional ventilation pipelines like the one at Continental Hospital—Bhai Bhai Engineering does not use a generic, one-size-fits-all fixed price list. Instead, we offer completely customized project pricing based entirely on the specific technical parameters of your exhaust system.
Our engineering team determines the final service cost by evaluating the following key variables during a physical inspection:
Total Pipeline Length (Running Feet / RFT): Cost is directly influenced by the exact distance the ductwork travels horizontally and vertically from the kitchen interior to the final outdoor exhaust discharge point.
Number of Suction Hoods & Canopy Dimensions: The total surface area of the stainless-steel hoods and the number of baffle filters requiring chemical soaking and heavy carbon removal.
Exhaust Fan & Centrifugal Blower Accessibility: The physical location and accessibility of the extraction fan unit. Systems that require specialized scaffolding, safety rigging, or roof access to dismantle and service are evaluated based on the labor involved.
Grease & Carbon Accumulation Level: The thickness and hardness of the solidified oil sludge inside the lines. Heavily neglected pipelines with multi-layered grease buildup require extra applications of heavy-duty degreasing agents and longer manual scraping hours.
Operational Scheduling: Whether the work needs to be fast-tracked during specific off-peak windows or overnight shifts to ensure zero operational downtime for your commercial kitchen.
Get a Free Site Survey & Exact Estimate: To ensure you receive the most competitive and honest rate for your facility, Bhai Bhai Engineering provides a completely free, no-obligation physical site survey inside Dhaka. Our technicians will inspect your complete hood, pipeline, and fan setup to deliver a transparent, itemized commercial quotation tailored precisely to your kitchen's needs.
Regular exhaust pipeline cleaning is a critical safety standard enforced heavily across multiple sectors in Bangladesh:
Government & Regulatory Compliance: The Bangladesh Fire Service & Civil Defence and the Bangladesh Food Safety Authority (BFSA) strictly inspect commercial premises. Regular duct cleaning avoids heavy fines, satisfies national fire safety audits, and keeps your operational license valid.
Healthcare & Hospital Sector (Non-Govt & Govt): In environments like Continental Hospital, pristine indoor air quality is vital. Uncleaned ducts can leak toxic smoke, foul odors, and carbon soot back into kitchen spaces, which can drift into patient wards, cabins, and sterile ICU zones.
Ready-Made Garments (RMG) Industrial Kitchens: Large factory canteens cooking for thousands of workers daily carry a massive fire risk. Regular pipeline cleaning keeps worker environments safe and protects multi-million-taka factory infrastructure from sudden fire outbreaks.
Hospitality Sector (Hotels & Restaurants): High-end eateries in Dhaka and Chittogram clean their lines routinely to ensure kitchen hygiene, keep exhaust fans running at peak performance, and avoid unexpected operational closures.
Bhai Bhai Engineering adheres to a strict standard operating procedure during every extraction pipeline cleanup:
Preparation & Area Isolation: We turn off the main electrical connections to the exhaust blower. All kitchen equipment, counters, and floors are wrapped in heavy-duty plastic protective sheets to catch chemical runoff.
Access Panel Installation: If the duct pipeline lacks clean-out panels, our structural team cuts professional access doors every 8 to 12 feet along the pipeline to ensure 100% internal reach.
Manual Scraping Phase: Technicians enter or reach inside the lines to physically scrape down thick layers of baked-on grease down to the bare metal.
Chemical Degreasing & Hot Water Jetting: We apply heavy-duty, biodegradable, food-safe degreasing agents to liquefy remaining carbon film, followed by a high-pressure hot water jet wash.
Fan Decarbonization & Re-Balancing: The blower wheel is completely stripped of grease deposits, tested for balance, and re-greased for quiet operation.
Final Polish & Testing: The hood surfaces are polished, plastic shields are removed, and the complete exhaust line is test-run to ensure smooth, high-velocity suction performance.
Setting up a new commercial kitchen ventilation infrastructure requires balancing initial structural installation costs with routine preventive maintenance:
New Installation Cost: Fabricating and installing a brand-new commercial exhaust pipeline (using premium 18 to 22-gauge rust-proof Galvanized Iron or Stainless Steel sheets, complete with canopy hoods, hanging supports, and an industrial centrifugal fan) generally ranges from BDT 1,50,000 to BDT 7,00,000+ BDT depending on your building's height and pipeline length.
Maintenance & Cleaning Costs: Scheduling routine professional cleaning every 3 to 6 months minimizes power draw, prevents fan motor burnouts, and avoids expensive emergency duct replacements. This makes preventive maintenance highly cost-effective compared to repairing fire damage.
Cleaning heavy industrial grease demands specialized equipment and expert technical knowledge.
Proven Institutional Experience: Our successful execution at Continental Hospital highlights our capability to meet strict institutional timelines and medical-grade hygiene standards.
Certified Technical Team: Our internal technicians understand airflow dynamics, mechanical safe-points, and professional grease removal techniques.
Advanced Equipment & Food-Safe Chemicals: We utilize specialized high-pressure hot water jet systems and eco-friendly chemicals that remove grease without corroding your stainless-steel duct pipelines.
Zero-Disruption Overnight Scheduling: We value your kitchen's operating hours. Our teams execute deep cleaning overnight or during off-peak windows to ensure your daily food operations run without a hitch.

Q1: How often should a commercial kitchen duct pipeline be cleaned in Bangladesh?
A: High-volume commercial kitchens (running 12 to 24 hours a day, such as hospitals, hotels, and busy restaurants) require deep cleaning every 3 months. Medium-volume corporate or school canteens can safely clean their lines every 6 months.
Q2: What is the main danger of leaving a kitchen exhaust pipeline dirty?
A: The main danger is a catastrophic fire. Cooking grease is highly flammable. If a flash flame occurs on the stovetop below, it can be sucked into the hood filters and ignite the grease layer inside the pipeline, creating a severe chimney fire that spreads through the building rapidly.
Q3: Will the duct cleaning process create a mess inside our kitchen?
A: No. The team at Bhai Bhai Engineering wraps all kitchen equipment, ranges, counters, and floors in heavy plastic film before starting. All liquefied grease and chemical runoff is funneled securely into containment drums, leaving your kitchen perfectly clean.
Q4: How long does a complete hood, pipeline, and fan cleaning take?
A: A standard commercial kitchen line cleanup typically takes between 4 to 8 hours, depending on total pipeline length and grease density. We routinely perform this service overnight to minimize operational downtime.
Q5: Do you provide certification for fire safety compliance or insurance audits?
A: Yes. Upon project completion, Bhai Bhai Engineering issues a formal service completion report complete with before-and-after photos. This report serves as valid proof of maintenance for fire insurance policies and government regulatory inspections.
