Dippr 801 -

Imagine designing a heat exchanger for a new refrigerant. The heat transfer coefficient depends on liquid thermal conductivity and viscosity. Using a generic estimation method (like a group contribution model) might give errors of 10-20% in these properties. That error compounds into undersized or oversized equipment.

The result is the , a critically evaluated collection of over 2,000 pure compounds, ranging from common solvents and hydrocarbons to specialty refrigerants and monomers. For each compound, the database provides temperature-dependent prediction equations for 36 distinct properties. dippr 801

DIPPR stands for the , a membership consortium within the American Institute of Chemical Engineers (AIChE). The "801" refers to the specific project number that began in 1980: a sponsored effort to compile, evaluate, and recommend the most reliable thermophysical properties for industrially important chemicals.

Whether you are a student learning Aspen Plus, a process engineer checking a pump curve, or a researcher developing a new solvent, DIPPR 801 is the benchmark you can trust. That error compounds into undersized or oversized equipment

With DIPPR 801, you have equations fitted to the best experimental data available—often with uncertainties under 1-2%. The result is a design that works the first time, saving millions in rework and downtime.
