Available in brass or stainless steel, these adjustable choke-valve snubbers protect pressure gages from pressure surges and fluid hammering, and help prevent needle pointers from jumping. A fine thread adjustment allows users to tune out harmful harmonic vibration. They are offered with 1/4-, 3/8-, and 1/2-in. NPT connections with pressure capabilities of 3,000–10,000 psi, depending on the size and material.

Complementing a line of integrated wireless field units, these analog, digital and analog/digital output modules enable processors to remotely monitor equipment and process conditions with no field wiring. They allow the integration of wireless monitoring instrumentation into existing control systems for a variety of applications. The analog modules provide four 4–20-mA analog outputs, the digital modules provide eight switch-closure outputs that report the conditions of the input switches and the status of the field units, and the analog/digital modules combine the capabilities of both.

The Model AHT-200 absolute humidity transmitter uses thermal conductivity sensors to measure moisture content at elevated temperatures up to 200°C. It is said to outperform conventional capacitive/resistance humidity sensors in harsh environments, and it can recover from exposure to deposits and condensation. Its range is 0–130 g/m3 with an accuracy of ±3 g/m3, which corresponds to ±2.3% RH at 35 g/m3 at 60°C.

The latest addition to Xchanger Suite 5.0 is the Xspe 5.0 component for rating and simulating spiral heat exchangers. The suite is also made more functional for designing, rating and simulating heat exchangers with the added support of the Cape-Open Thermodynamic Interface Version 1.0. —an international standard for interfacing physical property and unit operation  modules to compliant process simulators, such as HYSYS and Aspen Plus.

The ProVane pump has self-adjusting vanes to eliminate efficiency-robbing slip, thereby allowing it to maintain near-original output and consistency, even after significant wear. Available in both ductile iron and stainless steel, its heavy-duty rotor and low shaft-stiffness ratio, combined with its hydrodynamic bearing design, result in extended bearing life, improved efficiency and energy consumption, better volumetric performance, and longer life. Five sizes, ranging from 3/4-in.

Made rugged for demanding day-to-day operations, CPK shell-and-tube heat exchangers have removable bundles to prevents fluid intermixing and allow for tube expansion. Applications include heating and cooling electrolytes, boiler blowdown, intercoolers and aftercoolers. These heat exchangers are available with a variety of options, including a materials of construction, components and nozzle orientations.

Marketed as an alternative to conventional shell-and-tube designs, the Twisted Tube heat exchanger is recommended for applications that require increased heat transfer with either fewer shells or a smaller exchanger. Key to the its design are helix-shaped tubes arranged in a triangular pattern, which eliminates the need for baffles. In lieu of baffles,  each tube is supported by adjacent tubes, while fluid swirls freely along its length.

  These tube-in-tube sample-cooler heat exchangers are geared for applications involving high pressure, low flow and high differential temperatures. All models are made of Type 316L stainless steel with seamless tubes, and feature all-welded construction. Three standard models range in sizes from 0.50-in. to 1.00-in. outer tube dia., and from 0.25-in. to 0.50-in. inner tube diameters.

The AlfaNova plate heat exchanger is offered as an alternative to brazed plate exchangers.Typical applications. include refrigeration systems that use ammonia refrigerants or other cooling media that is corrosive to copper, district heating systems that use corrosive water, tap water systems and sanitary applications. Made of stainless steel, this heat exchanger is constructed using a bond technique that ensures the durability to withstand industrial processes that require extreme pressures and temperatures.

The No. 825 walk-in electric oven operates at up to 500ºF and can cure latex in the laboratory, eliminating the need to send it off-site. Inner workspace dimensions measure 54 in. wide × 72 in. deep × 72 in. high. Incoloy-sheathed tubular heating elements house 30 kW of power, and a 6,000 ft3/min, 5 HP recirculating blower provides horizontal airflow across the workload. Construction features include 4-in.-thick insulated walls, a 2-in.
