The Challenge: High Heat & Tight Spaces
A busy restaurant kitchen produces an immense amount of heat, smoke, and grease. This project comes with the challenges:
Neighbor Relations: Because the restaurant is a middle lot, exhaust cannot be discharged out the back or side. It must go vertically to the roof to ensure odors don’t affect neighbors while complying to local authorities requirement.
Acoustic Engineering: With businesses on both sides, the 3HP motor noise had to be muffled. The industrial silencer wasn’t just an “extra”—it was a necessity for compliance and being a good neighbor.
Shared Infrastructure: Wall scanning was vital because middle-lot walls are often shared or contain high densities of utility lines.
The Solution: A Hybrid Exhaust & Cooling System
To tackle the heat and smoke effectively, we proposed a Push-Pull System:
- Extraction: Removing smoke and grease efficiently.
- Make-up Air: Introducing fresh, cooled air to replace the hot air being removed, keeping the chefs comfortable.
Key Installation Highlights
1. Precision Scanning for Safety We don’t just drill and hope. As seen in the project walkthrough video, our team used digital wall scanners to locate concealed water pipes and electrical wiring before installation began. We learned from industry experience: “Measure twice, drill once” prevents costly accidents.
2. Noise Control with 3HP Silencer A powerful 3HP Motor that specifically tuned with high static pressure was required to generate enough force to push the fume all the way up to roof-top. However, high power usually means high noise. To solve this, we installed a specialized industrial silencer on the ducting stack. This ensures the system runs powerfully but quietly, keeping the restaurant compliant with local regulations.
3. Custom Fabrication
The Hood: A massive 9-foot (approx. 2.7m) stainless steel hood was fabricated to cover the entire cooking line.
The Ducting: The exhaust ducting was routed vertically up to the roof level to ensure proper dispersion of smoke and odors away from the street level.
Technical Specifications & Installation Details
To achieve the target temperature drop, we implemented the following technical configuration:
- Fixed Type Evaporative Air Cooler : 1 nos of CrystalAir AC-230
- Discharge Grille : 5 nos of 2×1 double deflection with independent airflow control.
- Kitchen Exhaust Hood : 1 nos of [9′ x 3′ x 20″] Island Style S/S exhaust hood
- Kitchen Exhaust Motor : 1 nos of branded 3.0HP 3-phase Axial Fan Motor with silencer
- Ducting: Rectangular Galvanized Steel (G.I)
- Installation Date: May 2025

The Results
The kitchen now enjoys a complete air exchange. The massive hood captures all cooking fumes, the silencer keeps the noise down, and the air cooler provides a comfortable working environment for the kitchen staff.
