Akton Psychrometric Suite V9 Industrial and Commercial Psychrometric Processes

The brand new Akton Psychrometric Suite V9 Windows desktop application has just been released in the spring of 2025. Akton is based on the same code base as the popular HDPsyChart V9 desktop software 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

Version 9 of Akton includes over 40 updates and bug fixes to Version 7. Just some of the updates include:

1. Added ASHRAE data zones from the 2015 and 2021 “Equipment Thermal Guidelines for Data Processing Environments – ASHRAE TC 9.9 Reference.”
2. Added world-wide ASHRAE climatic data from the 2017 and 2021 ASHRAE Handbook of Fundamentals. For 2017, weather data for over 8000 cities were added. For 2021, weather data for over 9100 cities were added.
3. Added 2023 U.S. TMY3 weather data from the Climate.OneBuilding.org database that includes 8760 hourly data for 1000s of cities in the U.S.
4. Added comfort data from ASHRAE Standard 55-2017 and 2020.
5. Added additional ASHRAE ventilation data that includes data from ASHRAE Standard 62.1-2016 and 2019
6. Includes a brand new feature called "templates" that allow you to store an unlimited number of psychrometric chart look-and-feels.

Akton Psychrometric Suite 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. Akton 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.

Akton 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.

Akton 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.

Akton 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 Suite.
