Akton Psychrometric ChartAkton Psychrometric Chart Industrial and Commercial Psychrometric Processes

The Akton Psychrometric Chart 7.0 Windows desktop application is now part of Carmel's library of HVAC software after acquiring the assets of Hands Down Software. Akton is based on the same code base as the popular HDPsyChart deskop tool, but is more focused on very high and low temperature and pressure psychrometric processes for applications such as:

  1. Agricultural Storage
  2. Drying, Food Processing, Dehydration
  3. Power Generation
  4. Chemical Manufacturing
  5. Petroleum Refining
  6. Primary Metals Refining
  7. Air Pollution Control
  8. Scrubber or Cooling Tower Evaluation
Akton Psychrometric Chart (APC) has been designed by professionals for engineers and other process managers who need power and versatility in their software tools but also demand cost effective quality. APC is unique in that it is developed through equations, not tables, so that calculations can be user configured to represent a wide variety of systems and conditions not typically possible with a standard chart.

APC is a powerful modeling tool that can be used to model a large variety of processes involving the thermodynamics of air water mixtures. Once a model of a system is created, it is easy to play out "what if?" scenarios. Solve complex problems using trial and error techniques.

APC dry-bulb temperature range is -100 to +2,000 °F, humidity ratios up to 1 lb/lb, altitudes up to 45,000 ft (pressure=0.2 psia) or pressures up to 100 psia ,both IP and SI units,and reports and charts in 13 different languages. Process modelling includes cooling coil with proper cooling coil curves, air mixing, desiccant dehumidification, evaporative cooling, sensible cooling, sensible heating and humidification.

APC also allows for complete psychrometric and process analysis, all graphically displayed on beautiful charts with unmatched accuracy. It also provides a professional state point and process report detailing all of the psychrometric and process values. Both IP and SI units are fully supported by Akton Psychrometric Chart.
