The No. 972 belt conveyor oven operates at temperatures up to 250°F (120°C). Electric heat is delivered at 40 kW per zone through two Incoloy-sheathed tubular elements, while two 10-hp recirculating blower motors provide 25,000 ft3 of vertical downward airflow to the workload. The oven features 4-in. thick insulated walls throughout an aluminized steel exterior/Type 304, 2B-finish stainless-steel interior, with continuously back-welded seams and wall penetrations that are fitted with compression elements.

The new A Series plate-and-frame heat exchangers (PFHEs) have been tested by an accepted American Refrigeration Institute (ARI) laboratory and have been registered as ARI 400-certified systems. The ARI 400 standard provides a uniform basis for comparison of liquid-to-liquid heat exchangers (see www.aridirectory.org/ ari/llhe.php). In compliance with this standard, the ARI 400 certified PFHEs cannot deviate from the published performance data by more than 5% with regards to heat capacity, and by no more than 10% with regards to pressure drop.

The INFI-SEAL technology for electric process heaters provides improved heater reliability and eliminates moisture-related start-up problems and is backed with a two-year limited warranty against moisture penetration. The INFI-SEAL transforms the MgO in a tubular heater’s cold section from hygroscopic to hydrophobic (from readily absorbing water to repelling water). Its treated heating elements exhibit infinite resistance to ground and do not absorb or retain moisture.

The direct-drive technology motor and drive system improves reliability, reduces maintenance and saves energy in cooling towers. It combines the technologies of the laminated finned-frame RPM AC motor with a high-performance permanent-magnet salient-pole rotor design. Its fan couples directly to the motor shaft and is controlled by the manufacturer’s VS1 cooling tower drive, providing variable-speed performance and quiet operation while using less energy than similar systems. Typically, right-angle gearboxes have troublesome maintenance problems in cooling tower installations.

Bath Armor metallic beads are eco-friendly and low-maintenance replacements for water in water baths, aluminum blocks in dry baths, and ice in ice buckets. Eliminating the water and ice reduces the chance of contamination, as well as the need for machines that produce ice or the need to change the water. The beads thaw, warm and chill samples with high thermal efficiency, and their performance is not influenced by temperature fluctuations caused by evaporation.

The Mitos hotplate adapter offers exact temperature control of micro-fluidic chips in conjunction with a range of hotplates. It has a compact footprint of 39 mm by 43 mm, and a temperature range from room temperature up to 300°C. It is digitally controlled with an external Pt100 thermocouple temperature probe. It is compatible with the manufacturer’s Mitos chips, including the Micromixer chip, the T-junction chip, the thin-layer chip and the Droplet Generator chip.

Balston 76 Series explosionproof air dryers can operate in hazardous environments without costly National Electrical Manufacturers Association (NEMA)-rated enclosures. They achieve a consistent –40°F dewpoint and can handle flowrates up to 40 std. ft3/min. The dryers use industrial-grade membrane technology to remove all humidity from compressed air without the need for electrical components, such as relays and contacts that pose a risk of fire or explosion.

Kenics heat exchangers are equipped with streamlined Kenics static mixer elements that provide heat-transfer rates three to seven times higher than those of conventional empty tubes, even with highly viscous, difficult-to-process materials. A continuous string of static mixer elements is located within each heat exchanger tube. Fluid flow is directed radially toward the pipe walls and back to the element, regardless of velocity. In addition, momentum reversal and flow division also contribute to mixing efficiency.

CF Series portable industrial chillers provide process-chilled water wherever it is needed. Models are housed in a compact cabinet, whose dimensions allow it to be moved through standard door openings so that the chiller can be set up near a process. This fully packaged system includes a robust high-efficiency refrigeration circuit that includes industrial-style scroll compressors. The integrated tank, pump, and controls make set-up and operation easy.

P-Series chillers are available in air-cooled, water-cooled and split systems in sizes from 1 to 50 tons, and special models up to hundreds of tons. These process chillers can be configured with internal or external tanks and pumping systems, and can be installed both indoors and outdoors. Air-cooled condensers are constructed with seamless copper tubing and the fins are mechanically bonded with aluminum. These condensers have aluminum fans and totally enclosed air over (TEAO) fan motors that are designed to prevent overload.
