AEW TECHNIK: Evaluating existing performance of Cooling tower using CFD techniques & CTI tests
Support for Third-Party Testing:
- CTI Licensed Agencies: AEW supports the use of CTI Licensed Agencies for testing.
- Approval Rights: AEW reserves the right to approve other agencies if guaranteed performance compliance is required.
- Witnessing Testing: AEW retains the right to witness any testing related to contract compliance.
- Third-Party Test Programs: Includes thermal performance, drift emissions, sound, and thermal certification.
Thermal Performance Testing:
New Cooling Towers:
- Essential for verifying performance against contract guarantees.
- Often linked to final milestone payments in cooling tower contracts.
Old Cooling Towers:
- Performance typically degrades over time, impacting plant and process efficiency.
- Testing helps isolate cooling tower performance from other equipment and assess financial impacts of modifications.
Drift Emissions Testing:
- Purpose: Measures the small fraction of circulating water emitted as drift.
- Importance: Drift can cause downwind corrosion, icing, and safety concerns.
- Regulation: Drift emissions are regulated by local air permits as particulate matter (PM) emissions.
- Standards Compliance: AEW measures drift and PM levels to ensure compliance with industry standards.
Sound Testing:
- Importance: Cooling towers can be significant sources of noise, leading to hearing loss.
- Standards: Testing follows CTI ATC-128 or other relevant test codes.
- Objective: Measures noise levels to assess worker exposure and identify ways to reduce noise emissions.
Thermal Certification:
- CTI Certification: Ensures new cooling towers or fluid coolers perform as specified.
- Program Details: Validates published thermal ratings through rigorous review and adherence to the STD-201 standard.
Plume-Abatement Testing:
- Purpose: Evaluates cooling towers designed to minimize visible plume from exhaust.
- Common Requirements: Often required in sensitive locations like airports, highways, and urban areas.
- Standards: Evaluations are conducted according to ATC-150 to verify plume-abatement performance guarantees
