Frequently asked questions
Common questions about HANKISON from 3G Electric.
What types of compressed air dryers does HANKISON offer?
HANKISON offers refrigerated, membrane, and regenerative desiccant compressed air dryers. Refrigerated dryers, such as the HPRB series, use a non-cycling refrigeration cycle to cool compressed air and condense moisture, achieving dew points around 50°F. Membrane dryers, like the HMM series, use selective permeation through hollow fibers to remove water vapor, suitable for lower flow applications. Regenerative desiccant dryers use a desiccant bed that is periodically regenerated, providing lower dew points for critical applications. Each type is available in various capacities and configurations to match system requirements.
What maintenance kits are available for HANKISON dryers?
HANKISON provides maintenance kits for their refrigerated and desiccant dryers, including drain service kits and repair kits. Examples include the HITFMK2 drain service kit for refrigerated dryers and the DHWJMK3 drain service kit for regenerative desiccant dryers. The HPRMK-1 maintenance repair kit includes components for servicing HPRB series dryers. These kits typically contain replacement elements, seals, and valves needed for routine maintenance, helping to extend equipment life and maintain performance.
What is the maximum operating pressure for HANKISON membrane dryers?
HANKISON membrane dryers, such as the HMM1-3F model, have a maximum operating pressure of 200 psi. This pressure rating is typical for the HMM series, which is designed for compressed air systems in industrial environments. The dryers also have a maximum operating temperature of 150°F, making them suitable for applications where compressed air is preheated or ambient conditions are elevated.
How do I select the correct HANKISON replacement filter element?
To select the correct HANKISON replacement filter element, identify the manufacturer part number from the existing unit or maintenance kit. For example, the 7493764 element is used for oil and particulate removal, while the 7456386 element is for particulate removal. Check the compatibility with your dryer model, such as the 802MM7 housing. Refer to the product specifications for flow rate, micron rating, and connection type to ensure proper fit and performance.
What is the dew point specification for HANKISON refrigerated dryers?
HANKISON refrigerated dryers, like the HPRB42-A, are designed to achieve a pressure dew point of 50°F, which corresponds to ISO Class 6 air quality. This dew point is suitable for general industrial applications, including pneumatic tools and instrumentation. For applications requiring lower dew points, HANKISON offers desiccant dryers that can achieve dew points as low as -40°F or lower.
