Paratherm MG, a specialty version of the MR (mid-range) heating/cooling fluid, is certified HT-1 food grade by the NSF (the designation that succeeds the retired USDA H-1 certification). It is recommended for processes operating from 0°C to 260°C. Another NSF HT-1-certified fluid, Paratherm LR, operates at lower temperatures, from –40°C to 204°C. Paratherm CR, developed for use down to –100°C, has a low viscosity that permits higher fluid turbulence, resulting in faster heat removal than silicone liquids or d-limonene-based fluids.

As their name indicates, the SS Harsh Environment Coalescing Filters are constructed of stainless steel (Type 304) and can be used under harsh conditions. They remove 99.99% of oil, water, rust and pipescale particles as small as 0.01 µm in size from compressed air and other gases. The filters are available in 1/4-in. to 1-in. line sizes with flow capacities to over 700 std. ft3/min. They come with automatic drains and a high-efficiency filter cartridge installed.

The CoolPoint vortex-shedding flowmeter for measuring and monitoring water flows in chemical processing applications now includes a totalizing capability and a scaled pulse output as a standard selectable option, which increases the meter’s abiliity to monitor and control the total amount of water used in a process. Accuracy has been improved to ±2% of actual flow, and repeatability remains at ±1% of actual flow.

The 3100/3200 Series of pressure transducers offers an all-stainless-steel design that is less than 1-in. in diameter and weighs 32 g. Capable of withstanding high levels of shock, vibration and electromagnetic discharges, the transducers have pressure-sensing ranges from 0 to 30,000 psi. They have unique temperature-compensation technology that delivers outstanding temperature stability. They provide full-scale accuracy of 0.25%, and long-term drift limited to 0.1% of full-scale per year.
