MISSISSAUGA, ON — Rittal Systems Ltd. says its VIP 6000 SK “represents a new dimension in cooling technology, [by] maintaining an optimum ratio between cooling capacity and volume.” With a cooling capacity of 760 BTUs, according to DIN 3168, the system is ideal for cooling small enclosures. Sensitive electronics control the small unit’s temperature. An air conditioner is required if the VIP system is in an environment where the ambient temperature exceeds 85C and the cooling fins cannot provide enough ventilation. The unit is designed to be used with the company’s VIP 6000 operator interface system. For optimal space use, two pre-mounted versions of the cooling system are available: either a left or a right condenser can connect the unit to the operator interface enclosure.

METERS: TAKE A CLEAR MEASURE OF WATER FLOW

Advertisment

MISSISSAUGA, ON — Davis Controls Ltd. has introduced a line of flowmeters from Fluidyne — a division of Emco — which are specifically designed for water flow applications. The Hydro-Flow Model 2100 Fixed Insertion Vortex Flowmeters are particularly suited, the company points out, “in applications when the pipeline can be depressurized for meter installation and/or servicing.”

The meter is designed for lines with diameters of four inches or greater. Its main feature is its accuracy, states the company. The vortex sensor is precisely positioned at a specific location in the flowline to measure local velocity. Microprocessor-based electronics provide a highly accurate linear output signal proportional to the average flow rate by continuously correcting for changes in the velocity profile that naturally occur as the flow is increased or decreased. Another added benefit is that the meter can easily be installed with either a weldolet or saddle-type clamp. It comes with a two-year warranty.

NEWSPRINT: CO2 GAS PROCESS INCREASES YIELD

LIDING, Sweden — AGA AB, a leading gas supplier, has developed a carbon dioxide process for newsprint producers that use deinked pulp as furnish. The CODIP process improver interacts with components present in the system to stabilize the variations in raw material, bleaching method and chemical additives. Launched at the end of 1998, the process is now used by a number of large paper mills in Scandinavia. The company said that the gas application increases paper machine runnability, DIP yield and efficiency of calcium carbonate, when used as a filler.

SOFTWARE: SURVEYING THE LAY OF THE LAND

WEST VANCOUVER, BC — Softree Technical Systems has recently signed a deal with the United States Department of Agriculture (USDA) Forest Services for its natural resources software, RoadEng — marking the 200th sale to the American forestry service. The software, which uses a Windows-based operating system, is a road design system ideally suited for rural roads or route location studies. It includes functions to do calculations for horizontal and vertical alignment design, cross sections, mass haul and slope stake. Using the software, a designer can work in various views: plan, profile or cross section. Changes made in one view are immediately incorporated and shown in others. The software developer specializes in surveying and engineering software for the natural resources sector.

MICROSCOPES: GETTING DOWN TO THE BARE ESSENTIALS

GUELPH, ON — Mandel Scientific Company Ltd. has introduced the latest Fourier transform infrared (FTIR) microscope from Mattson Instruments. The Momentum produces high-quality spectra with the use of a narrow-band mercury cadmium telluride (MCT) detector. The microscope system includes a completely new optical design, which provides extremely high sensitivity and precise spacial resolution; an infinity-corrected optics system that gives focus compensation; and an optical design that allows for simultaneous sample viewing during IR data collection. As well, the microscope system contains easy-to-use motorized aperture controls that can be automated, and a video capture system that allows multi-use sample viewing and photo-documentation of the sample. Many option packages are available to meet the particular microspectroscopy requirements of researchers, including dual detectors, rotatable grazing angles and attenuated total reflectance (ATR) lenses, as well as camera packages. The Momentum can be configured with Mattson’s Infinity and Genesis series of spectrometers.
