About this app

Title: PG Suite: Propylene Glycol Calculator
Description: PG Suite is a professional-grade tool designed for HVAC engineers, Renewable Energy experts and technicians. The app provides instant, accurate calculations of the base physical properties of Propylene Glycol water solutions, such as mass and volume concentration, freezing temperature, boiling temperature, density, absolute vapor pressure, specific heat capacity, thermal conductivity and viscosity.
Whether you are analyzing coolants or designing an HVAC loop, PG Suite delivers precise data and dynamic visual graphs directly on your mobile device.
Key Features:
✅ Concentration Adjustment Calculator Designed to help you quickly adjust the system concentration to achieve a target freezing point.
• Core Principle: Based on fluid exchange (Drain & Refill). A specific amount of the existing solution is drained and replaced with correction fluid, ensuring the total system volume remains unchanged.
• Flexible Inputs: Automatically calculates adjustments using Deionized Water (0%), 50% Premix, 100% Concentrate, or a Custom premix fluid.
✅ Density Calculator Calculates physical properties based on experimental data at atmospheric pressure (1 bar). Operates in two distinct modes:
• Mode 1: Calculate Mass Concentration based on measured Density & Temperature.
• Mode 2: Calculate Density based on Mass Concentration & Temperature.
• Outputs: Mass & Volume Concentration, Freezing/Boiling Points (at 1 bar).
✅ Properties Lookup - calculator for quick reference. Input a known parameter to find the rest:
• Input Solution Temperature.
• Input Mass or Volume Concentration.
• Outputs: Mass Concentration (Wt%), Volume Concentration (Vol% @ 20°C), Freezing Point, Boiling Point (at 1 bar), Density (kg/m^3), Absolute Vapor Pressure (bar), Specific Heat Capacity (kJ/kg.K), Thermal Conductivity (W/m.K) and Viscosity (mPa.s).
✅ Dynamic Graphing Visualize how fluid properties change with temperature using built-in plotting tools.
✅ Additional Benefits
• Offline Capability: Perform all calculations locally on your device—perfect for remote sites.
• Ad-Free Experience: A clean, professional interface without distractions.
• Multi-Industry Use: Adapted for various engineering sectors.
Perfect For:
• HVAC: Chiller and heating system design, troubleshooting and maintenance.
• Renewables: Adjusting Propylene Glycol concentration in wind turbine, solar or geothermal loops.
Streamline your engineering and diagnostic workflow with PG Suite.
