The No. 960 gas-heated, 550°F tunnel oven is used for processing various composite resins and fibers. The modulating gas burner is powered by 400,000 BTU/h, while a 12,500-ft3/min, 10-hp recirculating blower provides vertical downward airflow to the load. The oven features 4-in. insulated walls throughout, an aluminized interior and exterior, a motor-operated vertical lift door, side doors for workload access/maintenance and integral guide tracks at the workspace entry to support the user’s wheeled loading fixture, for faster start-up of the process.

Harper International will exhibit its advanced thermal processing technology to the advanced material processing and chemical industry. The firm provides customized thermal processing systems that require precise atmosphere controls and ultra-high temperatures. Harper provides research and development, pilot plant, full production and complete post sales support. The company’s technology center provides process development to optimize scaleup.

The BDHR series of boiler-blowdown heat-recovery systems are pre-engineered modules that include a plate heat-exchanger or optional shell-and-tube heat exchanger, pressure-relief valve, isolation valve and mechanical or electrical level controls. They recover up to 95% of the heat energy normally lost with conventional continuous blowdown separators. The resulting flash steam can be used to preheat boiler makeup water to heat the feedwater or the deaerator tank, or other fuel-saving uses. Modules are available in eight sizes of centrifugal blowdown vessels ranging from 8 in.

These vaporizers are designed for use in process industries such as chemical, petrochemical, textile, and others requiring large amounts of accurately controlled heat at high temperatures and low operating pressures. Recirculating fluids such as Dowtherm A, Dowtherm J and Therminol VP-1 can be maintained at temperatures as high as 750°F. Utilizing the vapor phase of these heat-transfer fluids promotes high heat-transfer rates and also close temperature control. Other liquids that can be vaporized include ammonia and liquefied gases.

The Gordon-Piatt brand Model FRMB rapid mix burner for gas- and gas/oil-firing boilers features a patented burner design that reduces both prompt and thermal NOx, thereby delivering ultra-low emissions. The FRMB burner capacities range from 125 to 600 boiler hp or 5,250,000 to 25,200,000 Btu/h. The firm offers guaranteed emissions performance of: less than 9 ppm NOx; less than 50 ppm CO; and less than 3 ppm VOC. A wide range of burner sizes is available for maximum efficiency and performance; oil can be fired as a back-up fuel when required.

The compact, heated MDH series dryers combine Nafion technology with a heating element to dry hot, wet, sample gases prior to analysis, increasing sample accuracy and reducing damage to downstream analysis equipment. The dryers were specifically created to dry gas samples with dew points higher than the ambient temperature, without requiring additional heating or insulation. Proprietary Nafion technology selectively removes only water from samples gases, leaving the rest of the gas sample unaffected.

The Insta Plug heat-exchanger-tube plug is a novel mechanical plug that forms a continuous internal-tube-torque pressure that safely and economically seals high-pressure processes where heat exchangers are needed. Made of nickel titanium (NiTi) alloy, the Insta Plug utilizes the alloy’s recovery properties (i.e., shape memory) to triple-seal the tube in order to plug high-pressure feedwater heaters in critical applications, as well as medium- and low-pressure applications.

The EZ Heater is a direct steam-injection heater that can be used in any process where instantaneous hot water is required. Its self-cleaning functions help to reduce overall maintenance expenses. The heater can reach temperatures up to 350°F with the ability to produce up to a 250°F temperature rise. It is available to accommodate flow ranges up to 600 gal/min. Each EZ HEater is customized to meet the user’s requirements.

This line of compact circulators is designed for applications where bench space is at a premium. Suitable for placement on shelves or mobile carts, the 8000 Series heat circulators feature a 6-L reservoir, a temperature range from 5°C to 200°C, and are available with a choice of four different controllers. Other standard features include an integrated simplex or duplex pump, rapid-response heater, and easy-access sample immersion. The units measure just 14-in. high and require less than 1 ft2 of bench space.

The SUPERMAX all-welded plate heat exchanger is designed as an alternative to shell-and-tube exchangers in elevated pressure and temperature applications. It is particularly suited to applications having a large flow imbalance, including gas or vapor condensers, economizers and related process and energy services, for pressures up to 70 barg (1,015 psi) and at temperatures up to 537°C (1,000°F) for standard range units. With alternating channels for hot and cold media, the unit can be configured to provide true countercurrent or co-current flow.
