Development and Testing

American Warming & Ventilating Product Development and Testing LaboratoryArchitects, mechanical engineers, contractors and facility owners rely on American Warming and Ventilating to meet their ever-changing damper and louver designs and cost requirements through product innovation and technological advancement.

The Product Development and Testing Laboratory is proof of AWV's pursuit of product excellence. Here, new product concepts and refinements to existing designs undergo rigorous testing before being introduced to the marketplace.

Designed and built in 1977 to test dampers to the exacting requirements of the nuclear power industry, the laboratory has one of the largest flow and pressure capabilities of any facility in the damper, shutter and louver industries.

Tests are performed following the AMCA Standard 500 Test Procedure, which is highly regarded by customers and contract users alike. AMCA audits the calibration of equipment, performance testing of products, and the laboratory itself every three years. Test results are audited each time a contract test is performed and witnessed. Contract customers receive all necessary documentation of the test results.

Air Duct Erosion of Fiberglass-lined Duct.
Bubble Tight Leakage.
Cycle.
Deflection.
Dif ferential Pressures to 50 in. wg.

Registration

The Product Development and Testing Laboratory is an AMCA-registered laboratory approved for testing in accordance with AMCA Standard 500. Tests are conducted in accordance with:

• AMCA Standard 500 for Louvers, Dampers and Shutters.
• AMCA Standard 210 Laboratory Methods of Testing Fans for Rating. Flow testing only.
• AMCA Standard 220 Test Methods for Air Curtains. Flow testing only.
• ASTM E477-80 Flow Testing only.
• UL 555 S Leakage Rated Dampers for use in Smoke Control Systems.

Equipment

Test Chambers:

Two 12' wide x 12' high x 28' long test chambers equipped with calibrated nozzles and pressure relief dampers. The airflow through each chamber is controlled by vernier dampers to ±2 cfm. One chamber is built to AMCA Standard 500 Figures 5.4/6.3 and the other chamber to 5.5/6.5. One horizontal plenum is built to AMCA Standard 500 Figure 5.7A.

Duct:

Nine duct sizes built to AMCA Standard 500 Figures 5.1, 5.2, and 5.3.
Square: 41" x 42", 36" x 36", 24" x 24", 18" x 18" and 15" x 15".
Round 48" , 18", 12", and 6" diameter.
Other sizes can be fabricated as required.

Fans:

Two: One 350HP capable of producing 80,000 cfm and 30 in. wg in Figure 5.5 chamber and 55, 000 cfm and 30 in. Figure 5.4 chamber. One 100HP capable of producing 8,000 cfm. At a lower volume it can develop 50+ in. wg in the 5.4 chamber.

Oven:

600°F Industrial Walk-In Oven that is 52" wide, 70" High and 70" Deep. The principle use of the oven is to test our combination fire/smoke and Leakage Rated (smoke only) to 350°F and tunnel dampers to 482°F.

Instrumentation:

Barometer, hygrometer, inclined and vertical manometers, micro-manometer, strain gauge recorder, temperature readouts, deflection gauges, torque wrenches, time chart recorder, pitot tubes, and cycle counters.
