CLIENT SUPPORT SERVICES
SUPPORT BEYOND EQUIPMENT SUPPLY
Envirovent provides practical engineering and technical support for existing dust-control, fume-extraction, industrial ventilation and dust-suppression systems.
Our Client Support Services are focused on helping clients understand the condition and performance of their systems, identify the causes of operational problems and develop practical recommendations for improved performance, reliability and maintainability.
Services may be provided for Envirovent equipment, legacy installations and suitable third-party systems. Each assignment is individually scoped according to the equipment, operating conditions, available technical information and the client’s specific requirements.
OUR SERVICES
System Audits & Condition Assessments
Structured site inspections covering extraction points, ducting, fans, dust collectors and associated equipment.
Troubleshooting & Root-Cause Assessments
Investigation of poor capture, dust escape, blockages, excessive wear, high differential pressure and recurring equipment problems.
Engineering & Upgrade Support
Concept development, equipment selection and engineering recommendations for repairs, modifications, debottlenecking and capacity upgrades.
Performance Evaluations & Optimisation
Operational assessments, measurements and recommendations aimed at improving system performance and efficiency.
Airflow Measurements & System Balancing
Measurement and assessment of airflow distribution, duct velocities, system resistance and extraction performance.
Maintenance, Spares & Field Support
Maintenance recommendations, critical spares identification, installation supervision, testing and commissioning support.
SYSTEM AUDITS & PERFORMANCE IMPROVEMENT
A system audit provides a structured assessment of how an existing dust-control, fume-extraction or ventilation system performs as an integrated whole, from the point of generation and capture through to collection and final dust discharge.
The scope of each audit is tailored to the system, the operating concern and the level of investigation required.
WHAT WE ASSESS
✓ Dust-generation sources, process conditions and operating sequences.
✓ Capture hoods, enclosures and extraction points.
✓ Duct sizing, routing, branches, dampers, leakage, wear and material build-up.
✓ Fans, motors, drives and operating duty.
✓ Bagfilters, wet scrubbers, cyclones and other dust-collection equipment.
✓ Cleaning systems, hoppers, dust-discharge arrangements and associated controls.
✓ Equipment condition, access and maintainability.
MEASUREMENTS & PERFORMANCE CHECKS
Where required and included in the agreed scope, the assessment may be supported by:
✓ Airflow and duct velocity measurements.
✓ Static pressure and differential pressure measurements.
✓ Fan duty and system resistance assessments.
✓ Checks of extraction points and airflow distribution between branches.
✓ System balancing and damper-setting checks.
✓ Review of relevant operating parameters, including compressed air, water flow or spray pressure, where applicable.
TYPICAL PROBLEMS WE INVESTIGATE
✓ Poor dust capture and visible dust escape.
✓ Uneven airflow distribution between extraction points.
✓ Dust settlement and recurring duct blockages.
✓ Excessive wear, leakage or corrosion.
✓ High or unstable differential pressure.
✓ Fan underperformance and insufficient extraction.
✓ Recurring filter, cleaning-system or dust-discharge problems.
TYPICAL AUDIT DELIVERABLE
Depending on the agreed scope, the client receives a concise engineering report recording the observed system condition, available measurement results, identified performance constraints and likely causes of the problems investigated.
The report includes prioritised recommendations and proposed next steps. Where further modifications are required, detailed engineering and implementation support can be offered as a separate follow-on scope.
