Products
We offer three distinct categories of product for sale.
- The PPDS Suite of Software
This is the flagship product in TUV NEL's software portfolio. It comprises a set of four tools that combine to provide a complete solution for your thermophysical properties.
The suite consists of PPDS, the main calculation engine; DataExpert, the pure component data analysis tool; PFIT, the tool for fitting BIP parameters; and pConfig, the tool for maintaining data. PPDS may be deployed as a stand-alone application on an individual PC workstation or as a fully networked client/server implementation across a company’s intranet. With a variety of interfaces available to suite almost every situation, PPDS is the ideal solution for a more cost effective use of key thermodynamic information across a company.
- Website Development
From the skills developed by producing the PPDS family of websites (ppds.co.uk and ppds.net) centre staff have extended their reach into developing technical websites for both internal and external customers.
- Bespoke Software
We have developed a number of applications to aid our customers integrate their technical software. These have ranged from VBA driven reporting tools through to client / server based applications and intranet web-site development.
