Mistral Associates, established in 1984, supplies RAC Expert System Application Engineering Software to currently 140 countries. Representing over 95% of the world's population. Of the remaining 58 recognised sovereign states, home to around 5% of the world's population, half do not have a reliable electricity supply and in some cases no electricity supply at all.

Most of Mistral's revenue stream, over 90% of which is ploughed back into the company in pursuit of further RAC industry research, product development, essential software coding upgrading and interactive database creation and updating, comes from annual leasing of program access licences.

A smaller part of Mistral's revenue stream, around 20%, comes from distribution of 'White Label' excerpt versions of Mistral's world-leading systems. Also referred to as Sponsored versions.

Sponsored versions will generally only feature audited RAC application equipment product databases featuring products manufactured or distributed by the sponsor. Whereas full program versions will feature all available product selection data, with the permission and verification of the supplying manufacturer and/or their officially authorised distributor.

Sponsored versions will generally only permit project maximum space volumes up to 10,000 cubic metres (and 6 metres in height). Mistral full program access versions cope with space volumes up to 250,000 cubic metres (and 25* metres in height. *Can be further increased via application of 'Special Feature Code').

Mistral full program access versions include many additional interactively linking programs performing additional engineering functions. For example: Multiple circuit and multiple load refrigerant pipe sizing. Coldroom costing and customer quotation generation. Refrigeration Transport applications for Lighters (container transport), trucks, marine and aircraft. Dedicated Beer and Wine Cellar heat load calculation. Dedicated Food Preparation Room load calculation. Simultaneous, unlimited multiple room calculations for both Air Conditioning and Commercial and Industrial Refrigeration. Agricultural refrigerated produce store load calculations involving specifically suited insulation types.

Mistral full program access versions will allow switching coldroom and freezer design studies working in either internal or external dimensions. User switchable even after program installation.

Mistral full program access versions include tools for user database editing along with user support for database creation and editing.

Mistral full program access versions include 'Special Feature Code' access for purposes of over-riding or extending scope of program dynamic error trapping limits, along with appropriate user support. Only advised for use by experienced or qualified engineers.

Mistral full program access versions can universally open all saved project calculation files and allow further editing and re-saving if desired, including #.awc, #.clw, #.cwc and #.lwc files. The reverse, that is a sponsored program version opening a project calculation file created using a full program version is not always possible. Due to the greater operating scope of full program versions.

Mistral full program access versions generally all allow simultaneous multi-lingual operation in ten world dominant languages. Meaning a project can be completed and saved in one language and subsequently opened, edited and re-saved in another language.
