HANKISON

Hankison is a manufacturer of compressed air treatment equipment, with a product history that includes refrigerated dryers, desiccant dryers, membrane dryers, coalescing and particulate filters, and related accessories. The brand is part of the broader compressed air solutions market and is known for equipment used to remove moisture, oil, and particulate contamination from compressed air systems. Hankison products are commonly specified in industrial settings where compressed air quality affects process reliability, tool performance, or product quality. 3G Electric supplies Hankison compressed air dryers, filters, and maintenance kits to industrial buyers worldwide. The product range includes non-cycling refrigerated dryers designed for high inlet temperature applications, with capacities from 20 cfm to 125 cfm and pressure dew points of 50°F. These units operate on 115V AC or 230V AC and use NPT connections from 3/4 in to 1 in. Power consumption ranges from 0.69 kW to 1.97 kW depending on capacity. The high inlet temperature design allows the dryer to handle compressed air that has not been pre-cooled, which is common when the compressor is located close to the dryer or when ambient conditions are elevated. Hankison also offers membrane compressed air dryers, such as the SMM3-4F and HMM3-4F models, which use selective permeation to remove water vapor. These membrane dryers are rated for 9.5 cfm to 9.7 cfm, with maximum operating pressures of 200 psi and maximum operating temperatures of 150°F. They feature 1/2 in NPT connections and are available with automatic drain options. Membrane dryers are often used in point-of-use applications, instrument air systems, and areas where a refrigerated dryer is not practical. The Hankison line also includes coalescing filters, particulate filters, and maintenance kits that support the dryers and filters. These components are used to remove oil aerosols, water droplets, and solid particles from compressed air. Filter elements and kits are available for scheduled maintenance, helping to maintain pressure dew point and air quality over time. 3G Electric supports the Hankison line by stocking a range of dryers, filters, and maintenance kits, and by providing specification data, model selection assistance, and quotation services for buyers who need to match equipment to their compressed air system requirements. The product data includes flow capacity, connection size, voltage, power consumption, dew point, maximum operating pressure, and maximum operating temperature, allowing plant engineers and maintenance managers to verify compatibility before purchase. For procurement specialists, 3G Electric provides a single source for Hankison dryers and replacement parts, with the ability to ship globally. The focus is on supplying the correct model for the application, whether it is a small membrane dryer for a single workstation or a larger refrigerated dryer for a main air line. Hankison equipment is typically installed after the air compressor and receiver, and before filters and point-of-use regulators. The dryers are used in applications such as pneumatic controls, instrumentation, paint spraying, packaging, and general industrial manufacturing. The non-cycling refrigerated dryers maintain a constant dew point by continuously running the refrigeration circuit, which can be beneficial in applications with steady loads. The high inlet temperature capability means the dryer can accept air directly from the compressor without an aftercooler in some cases, although system design should always be verified. Membrane dryers offer a compact, low-maintenance alternative for lower flow rates and can achieve dew points down to 40°F. They have no moving parts and require only a small purge flow to carry away moisture. The SweepSaver technology used in some Hankison membrane dryers reduces purge air consumption by directing a portion of the dry air back through the membrane bundle. This can lower operating costs compared to standard membrane dryers. 3G Electric carries Hankison products with manufacturer part numbers such as HITN20, HITN25, HITN35, HITN50, HITN75, HITN125, SMM3-4F, and HMM3-4F.

Frequently asked questions

Common questions about HANKISON from 3G Electric.

What is the difference between Hankison non-cycling refrigerated dryers and cycling refrigerated dryers?

Hankison non-cycling refrigerated dryers, such as the HITN series, run the refrigeration compressor continuously and use a hot gas bypass valve to modulate capacity. This maintains a stable 50°F pressure dew point regardless of load fluctuations. Cycling dryers, by contrast, turn the refrigeration compressor on and off based on demand, which can allow dew point to rise during low-load periods. Non-cycling dryers are often chosen for applications where a consistent dew point is required, such as instrumentation or critical process air. They may use more energy at partial load but provide steady moisture removal.

What flow capacities are available in the Hankison HITN high inlet temperature dryer series?

The Hankison HITN series includes models rated at 20 cfm, 25 cfm, 35 cfm, 50 cfm, 75 cfm, and 125 cfm. These correspond to part numbers HITN20, HITN25, HITN35, HITN50, HITN75, and HITN125. All models in this series achieve a 50°F pressure dew point and are designed for high inlet temperature applications. Connection sizes range from 3/4 in NPT on smaller models to 1 in NPT on larger models. Voltage options include 115V AC and 230V AC depending on capacity. Power consumption ranges from 0.69 kW to 1.97 kW.

How does a Hankison membrane air dryer work, and what are the typical applications?

Hankison membrane air dryers, such as the SMM3-4F and HMM3-4F, use a bundle of hollow fibers that selectively permeate water vapor. As compressed air flows through the fibers, water vapor passes through the membrane wall and is carried away by a small sweep flow of dry air. This produces a pressure dew point as low as 40°F. Membrane dryers have no moving parts and require minimal maintenance. They are typically used for point-of-use applications, instrument air, and low-flow processes where a refrigerated dryer is not practical. Maximum operating pressure is 200 psi, and maximum operating temperature is 150°F.

What maintenance kits are available for Hankison compressed air dryers and filters?

Hankison offers maintenance kits that include replacement filter elements, drain valves, and other wear components for their dryers and filters. These kits are model-specific and are intended to support scheduled maintenance. For refrigerated dryers, kits may include refrigerant filters, drain strainers, and solenoid valves. For filters, kits typically include coalescing or particulate elements. 3G Electric supplies Hankison maintenance kits and individual replacement parts. Buyers should reference the dryer or filter model number and serial number when ordering to ensure the correct kit is supplied.

What is the maximum operating pressure and temperature for Hankison membrane dryers?

Hankison membrane dryers, including the SMM3-4F and HMM3-4F, are rated for a maximum operating pressure of 200 psi and a maximum operating temperature of 150°F. These ratings apply to the standard models. Operating above these limits can damage the membrane fibers and reduce drying performance. For applications with higher pressures or temperatures, consult the manufacturer for alternative models or consider a different dryer technology. The membrane dryers have 1/2 in NPT connections and are available with automatic drain options.

Can Hankison refrigerated dryers be used with high inlet temperatures without an aftercooler?

Hankison high inlet temperature non-cycling refrigerated dryers are specifically designed to accept compressed air at elevated temperatures, which can occur when the dryer is installed close to the compressor without an aftercooler. These dryers use a larger refrigeration circuit and a pre-cooler to handle the higher heat load. However, the maximum allowable inlet temperature is model-specific and should be verified from the technical data. In general, an aftercooler and moisture separator are still recommended to reduce the load on the dryer and improve overall system efficiency. Always confirm the inlet temperature limit for the specific HITN model.
