Exhaust & Dilution Ventilation Systems

Exhaust and Dilution Ventilation Systems are designed to remove contaminated, hot, humid, or polluted air from enclosed spaces and replace it with fresh make-up air to maintain safe and acceptable environmental conditions. Exhaust ventilation focuses on extracting unwanted air, while dilution ventilation reduces contaminant concentration by mixing it with fresh air.

We install and service Toilet Exhaust Ventilation Systems, Kitchen Exhaust Systems, DG Room Ventilation Systems, Basement Exhaust Systems, Electrical Room Ventilation, Laboratory Exhaust Systems, Chemical Fume Exhaust Systems, and Industrial Dilution Ventilation Systems. Each system is engineered based on contaminant type, heat load, and safety requirements.

Yes, we offer comprehensive Annual Maintenance Contracts (AMC) for exhaust systems including fan inspection and lubrication, motor alignment verification, duct inspection and cleaning, hood cleaning (for kitchen exhaust), damper calibration, electrical panel servicing, vibration monitoring, and safety compliance checks. Customized AMC plans are available for commercial and industrial facilities.

Poor extraction performance is commonly caused by fan motor failure, duct leakage, backdraft issues, damper malfunction, electrical control faults, or excessive smoke/odor accumulation. We provide rapid corrective maintenance with root cause analysis to restore effective contaminant removal and air circulation.

Our installation includes axial/centrifugal exhaust fan installation, inline fan installation, wall-mounted exhaust systems, duct fabrication and erection, kitchen exhaust hood installation, make-up air system integration, fresh air compensation, louvers, backdraft dampers, chimney/discharge stack installation, and electrical wiring with control panel integration. Engineering focus includes exhaust airflow CFM calculation, contaminant dilution rate, static pressure estimation, and compliance with fire codes.

Our commissioning services include airflow measurement, static pressure testing, capture efficiency verification, motor load and ampere testing, noise level testing, smoke testing for airflow direction, backdraft damper testing, and functional testing of control systems. Detailed commissioning reports are issued confirming airflow and performance compliance.

Yes, we execute retrofitting services including upgrading to high-efficiency exhaust fans, addition of make-up air systems, duct resizing and airflow optimization, noise reduction modifications, fire-rated duct integration, automation panel modernization, and emission control improvement. Retrofitting improves safety, odor control, and regulatory compliance.

We provide timer-based control systems, CO-based exhaust control for enclosed spaces, VFD integration for exhaust fans, BMS integration, pressure-based control logic, and alarm/safety interlock configuration. Automation improves energy efficiency and operational reliability.

Energy efficiency is improved through static pressure optimization, fan efficiency analysis, duct resistance reduction, airflow redistribution studies, power consumption audits, and performance benchmarking. Energy optimization improves operational efficiency and reduces electricity consumption.

Regular preventive maintenance includes fan inspection and lubrication, motor alignment verification, duct inspection and cleaning, hood cleaning (for kitchen exhaust), damper calibration, electrical panel servicing, vibration monitoring, and safety compliance checks. This ensures reliable exhaust performance and long equipment life.
