Case Study: Hospital Generator Exhaust Silencer; Project – Deenanath Mangeshkar Hospital, Pune
Project Overview
A leading hospital in Mumbai was experiencing significant noise disturbance from its diesel generator exhaust system. The high noise levels were causing discomfort to patients, hospital staff, and visitors, particularly in areas located close to the generator installation.
The hospital management approached PMT TECH to develop an effective noise-control solution that would comply with stringent acoustic requirements while ensuring uninterrupted generator operation.
Challenge
Hospitals require a quiet environment to support patient recovery and maintain a comfortable atmosphere for healthcare professionals. The existing generator exhaust system was generating excessive noise, resulting in:
- Patient discomfort
- Noise complaints from nearby occupied areas
- Concerns regarding hospital acoustic standards
- Need for reliable noise reduction without affecting generator performance
The customer required a solution capable of achieving exceptionally low noise levels while maintaining proper exhaust flow characteristics.
Our Solution
After a detailed assessment of the generator operating conditions and site requirements, PMT TECH designed and manufactured a high-performance exhaust silencer specifically engineered for the application.
Key Features
- Customized acoustic design
- Optimized pressure-drop characteristics
- Heavy-duty industrial construction
- Designed for hospital noise-control requirements
- Suitable for continuous generator operation
The silencer was engineered to achieve a noise level of 55 dBA at 1 meter, meeting the customer’s stringent acoustic expectations.
Results
Following installation and commissioning, the generator exhaust silencer successfully reduced exhaust noise to the targeted level of 55 dBA at 1 meter.
Achieved Benefits
✓ Significant reduction in generator noise
✓ Improved patient comfort and hospital environment
✓ Compliance with customer acoustic requirements
✓ Reliable operation without impacting generator performance
✓ Enhanced satisfaction among hospital management and facility personnel
Customer Confidence and Repeat Order
The successful implementation of the first project resulted in a high level of customer satisfaction. Based on the proven performance of the installed silencer, the hospital subsequently placed an order for an additional silencer for another generator application within the facility.
This repeat business reflects the customer’s confidence in PMT TECH’s engineering capabilities, product quality, and commitment to delivering effective industrial noise-control solutions.
