To help you make up your mind about which refrigeration load calculation software is the world's best (though not necessary the least expensive) we have prepared a short check list for you. You may wish to present it to Mistral's competition.

Just a few of Mistral’s Coldwind Pro program features that set it apart from the rest.

Ask these questions of Mistral's competitors and imitators. Does their program:-

1) Allow switching between operation in either SI and Imperial units at any time, automatically changing every unit, every description, database selection, algorithm, equation, factor and calculation, without incurring cumulative rounding errors?

2) Impose any limits upon the number and relative angles to one another of wall surfaces?

3) Provide for inclusion of varying wall building and insulation materials, even within the length of each wall?

4) Provide for entry of multiple food and other perishable products, along with various storage materials, items and stillages etc, all selectable from comprehensive, illustrated, tiered databases? Databases which are also user editable even while programs are running.

5) Allow reloading of previously filed calculations in such a way that they are guaranteed to be still totally dynamically interactive?

6) Provide for multiple suites of coldrooms and/or freezers and which can be segregated and ‘zoned’ to different refrigerant circuits?

7) Come complete with total world meteorological databases arranged by continent, country and geographic co-ordinates/city name allowing automatic and instant recomputation of a design load at 15 minute intervals across the entire 24 hour day for all 365 days of the year to an accuracy of plus or minus 250 metres across planet earth’s surface via a single mouse click upon any one of 66,000 zoomable world maps?

8) Provide facility for selection and balancing then placing scaleable, rotateable images on room plan design form of refrigeration equipment from thousands of daily maintained and updated databases that are checked and approved by the equipment manufacturers themselves?

9) Come with comprehensive, dynamically linked and FOCUSED, colour illustrated Help pages designed to standard Microsoft Windows ‘best practice’ recommendations?

10) Come supplied with over 135,000 interactive, user editable, PRE-ENGINEERED, coldroom and freezer room industry standard designs, approved by a consortium of the world’s leading food industry ‘End Users’ that can be selected using fewer than 10 key presses and in under 7 seconds?

11) Allow automatic ‘Return Key’ navigation as a parallel and frequently faster alternative to Mouse key operation?

12) Allow export of automatically generated comprehensive ‘presentation quality’ summary printouts, text, dimensioned line drawings, and colour images and photos, in various MS Windows Word Processor standards, along with user editable sales quotation presentation formats complete with recommended but user editable, standard paragraphs and phrases?

13) Last but by no means least. The most important feature of all.

Does the program operate with total dynamic ERROR TRAPPING?

As without it the program has the potential to unwittingly embarrass you at best and destroy your business at worst. If your potential software provider doesn’t understand this question then we recommend you terminate all future communication with them.
