Testing Laboratory |
|
Twin City Fan Companies, Ltd.'s (TCFC) airflow, acoustics, safety, and reliability
testing facility is used to conduct numerous types of tests for quality assurance,
research and development, product certification (AMCA license), and product safety
(UL listing). It is maintained as an AMCA Accredited Laboratory* for air performance
testing (per AMCA Standard 210), inlet and outlet sound testing (per AMCA Standard
300), and is a member of Underwriters Laboratories’ (UL) Client Test Data
Program (CTDP). The laboratory regularly tests Axial Fans, Mixed Flow Fans, Jet
Fans, Power Roof Ventilators, and Centrifugal Fans and Blowers.

In 1993, the laboratory was expanded to include a semi-reverberant room, qualified
per AMCA Standard 300, and moved away from downtown noise sources to its present
suburban site next to low-traffic parkland.

High-pressure chamber data acquisition system
(air and sound testing)
|
|
|
|
Our custom-designed data acquisition systems display results in real time and eliminate
human error and bias. This allows for rapid, accurate testing. As required for AMCA
laboratory accreditation, TCFC results are periodically compared with tests of the
same fan’s performance in the AMCA laboratory to verify the accuracy of results.
Similarly for UL’s CTDP, all UL test standards that the TCFC laboratory is
listed for are witnessed annually by UL auditors to assure test procedures are maintained
to UL requirements. |

Engineers and Qualified Laboratory Technicians staff the laboratory. TCFC is continuously
upgrading its testing capabilities and equipment. Recent improvements include jet
fan testing capabilities per AMCA proposed 250 draft and an additional high-pressure
test chamber capable of testing up to 80 in.-w.g. The new high-pressure chamber
uses a state-of-the-art National Instruments data acquisition system using a PXI
1010 PC Chassis that ties in all of the transducers and data acquisition cards required
for performance testing. This new system meets or exceeds all AMCA/ASHRAE/ANSI requirements.
*Product performance data based on tests in an AMCA Registered Laboratory are not
to be construed as being licensed to bear the AMCA seal. For more information visit
the AMCA web site.
