To obtain the most accurate static pressure readings of a dryer, the following guidelines should be conformed to. The reading should be taken in a straight section of duct, a minimum of ten (10) times the diameter of the duct (i.e. 10-inches [25.4 cm] diameter duct, a straight section 100-inches [254 cm] in length). The reading should be taken a minimum of 8-1/2 times the diameter upstream of the dryer or nearest elbow, and 1-1/2 times the diameter downstream of the Pitot tube. The following is an example showing the proper location to take a static pressure reading.

In designing a dryer exhaust duct system, it is not necessary to compute the friction loss of the ductwork. The friction loss (static pressure) is predetermined to not exceed 0.3 inches (0.74 mb) of water column (W.C.). This maximum allowable static pressure is the same for ALL model dryers and is calculated to provide maximum dryer efficiency. It is necessary to determine the total equivalent length of the duct system. The total equivalent length of the duct system is the actual length of the duct added to the equivalent length of ALL the fittings. The equivalent length of a fitting, is the length of straight duct of the same size as the fitting in which the friction losses are equal. Equivalent lengths must be determined for ALL elbows, as well as, any entries which may be incorporated into a common duct system for multiple dryers. The total equivalent length is then used with the total cfm exhaust rating of the dryer(s) to calculate the minimum round duct diameter. When designing a single common duct system for multiple dryers, each individual dryer exhaust duct enters the main common duct.

AD-25, AD-30 specifications

American Dryer Corporation (ADC) has long been a trusted name in the commercial laundry equipment industry. Among their notable offerings are the AD-30 and AD-25 dryers, which are engineered to provide exceptional performance, reliability, and efficiency.

The AD-30 dryer is designed for high-capacity laundry operations, making it an ideal choice for large businesses such as hotels, hospitals, and laundromats. With a maximum drying capacity of 30 pounds, the AD-30 features a robust construction that can withstand the demands of heavy usage. Its powerful airflow technology ensures quick drying times, improving productivity and minimizing energy consumption. The dryer is equipped with a microprocessor control that offers multiple cycle options and customizable settings, allowing operators to tailor each drying cycle based on the specific fabric types being processed.

On the other hand, the AD-25 serves smaller operations with a capacity of 25 pounds, making it an efficient choice for businesses with moderate laundry needs. Similar to the AD-30, it incorporates advanced airflow technology to enhance drying efficiency. The AD-25 also features easy-to-use controls and programmable settings, providing flexibility for various drying requirements. Both models come with an easy-to-clean lint filter that helps maintain optimal air quality and prolongs the life of the machine.

In terms of construction, both dryers are built with durability in mind. Their stainless steel exteriors are not only aesthetically pleasing but also resistant to corrosion, ensuring they remain in good condition over time. The design of these dryers incorporates vibration reduction systems to minimize noise during operation, contributing to a more pleasant working environment.

Energy efficiency is a hallmark of American Dryer Corp products, and both the AD-30 and AD-25 are no exception. They are designed to consume minimal energy while delivering maximum drying performance, which can lead to significant cost savings over time.
