Silicone Jamb Seals - Longevity & Performance at 2,000,000 Cycles
Tamco dampers have a service life of over 20 to 30 years. A common question arises: will the silicone jamb seals used on Tamco dampers withstand the thousands of cycles that air control dampers undergo during their service life? To evaluate the longevity of Tamco’s silicone jamb seals, the company has been conducting extensive tests to measure the effects of prolonged cycling under various conditions on the seals’ physical appearance, durability, and air leakage performance. This paper presents the latest results, objectives, methodology, and comparative data from cycle testing, which has exceeded the two-million-cycle mark.
Damper Blade Operation - Parallel vs. Opposed Blades
This whitepaper addresses the question: “What is the difference between parallel blade and opposed blade damper operation, and when should one type be used over the other?” By considering damper applications, airflow volume, pressure loss, leakage, and torque requirements, this paper explains how your choice of blade operation can significantly impact the effectiveness and efficiency of your system.
Jamb Seal Performance: Tamco Silicone vs. Aluminum and Stainless Steel
Why does Tamco use silicone jamb seals for their air control dampers instead of aluminum or stainless steel? Control dampers with high leakage rates directly contribute to increased building operating costs. Since blade and jamb seals are the two primary factors affecting a control damper’s leakage rates, this paper evaluates jamb seal materials to determine which provides long-lasting, consistent performance.
Thermal Damper Efficiency
How do you test the thermal efficiency of a damper and what do the results actually mean? This paper examines the various methods for measuring and defining thermal efficiency in dampers. It explores AMCA’s Thermal Efficiency Test Rating and the factors involved in thermal isolation, providing guidance on the proper assessment of thermal performance in dampers. As the first company to introduce thermally insulated dampers and thermal break technology, Tamco has remained committed to delivering excellence in thermal performance and energy-efficient products.
Tamco's AMCA Certified Laboratory
What does it take to get a pressure drop and leakage test laboratory certified by AMCA? This paper explores and explains the required laboratory components, accreditation by AMCA, and benefits of having an in-house test facility in order to enhance new product development and support continuous product improvement.
UV Light Resistance Testing
Are Tamco blade and jamb seals resistant to constant exposure to UV light, and what effect does this exposure have on leakage performance throughout a Tamco damper’s service life? This paper discusses the UV light exposure testing Tamco has been conducting since 2013, including the test methodology and results. Over eight years (96 months) of testing, UV light exposure has demonstrated the resilience and durability of Tamco’s silicone jamb seals, making our product a highly attractive and cost-effective choice.
Tamco Damper blades - Adjacent Blade Alignment
Why might a damper blade not seem to lay completely flat when the damper is fully closed? On rare occasions, damper blades do not lay completely flat when in a closed position. This paper explains why this can occur and that the damper is still fully functional, and troubleshooting if visible light lines are observed.
Tamco Airfoil Blade Shape: Definition & Comparison of Blade Types
When specifications call for dampers with airfoil shaped blades, what exactly is an airfoil shape? How does it differ from other designs used in the damper industry? This paper establishes familiarity with the true definition of an airfoil and how it pertains specifically to damper blades. Addressing the common misconception that in order for a damper blade to be considered airfoil, it must be shaped like an airplane wing. Tamco unique blade design combined with intricate frame features allow Tamco dampers to provide the lowest pressure drop in the industry today.
