Softeners are used to remove the hard calcium and magnesium minerals from water. It works by replacing the calcium and magnesium ions in hard water with sodium ions. A complete softener system consists of a small bed of plastic beads or a chemical composition matrix called zeolite that contains the sodium ions. When the water passes through the matrix or the bed of beads, the sodium ions change places with the calcium and magnesium ions. When all of the sodium ions are expended, the matrix or beads are soaked in a salt solution to regenerate the source of sodium ions.

Software for data-acquisition includes a main program written in floating point BASIC and machine language interrupt routine. Software for data acquisition processors runs on both the data acquisition processor and on the host PC.

HVAC software is designed for commercial heating and cooling load calculations, residential heating and cooling loads, duct sizing, psychrometrics, refrigeration, and HVAC estimating applications. The features of this software include a metric-english converter, single-state psychrometric calculations, mixed-air psychrometric calculations, duct sizing calculations, general pipe sizing and pump curve analysis.

Materials science software supports researchers throughout the chemicals, pharmaceuticals, and materials based industries, enabling the discovery of novel materials and properties. The software combines simulation and informatics with high quality graphical visualization of materials and molecular structure. This software contains materials properties databases, phase diagram collections, and crystallography software.

Thermochemistry software can analyze solid or liquid solutions, non-stoichiomentric compounds, high-pressure systems, and concentrated aqueous systems. It is the choice for straight thermodynamic analyses of systems of interest. It has direct plotting of phase diagrams. The additional features include a module for generating optimal system thermodynamic models from available thermodynamic & phase equilibria data, and a model for staged reactor system.

Thermophysical properties software calculates thermophysical properties of fluids and solids, with emphasis on low temperatures. All properties calculations are referenced to published scientific papers. It can calculate 28 different thermophysical properties of 36 different fluids having normal boiling points from 4 K to room temperature. Properties are calculated for temperatures from the triple point to the upper limit of available data for that fluid (range 400 to 5000 K), and for pressures to about 100 bars (different limit for each fluid).
