Mistral EC 
Mistral USA
software is designed to be as simple to use as is possible with a computer.
Programs that closely follow methods most engineers use when doing the job manually.
In other words programs that operate intuitively, in the same way we were all taught and therefore now naturally think. Only MISTRAL offers you the unique
advantage that when inevitable mistakes are made (and very few of us can claim to have never inadvertantly added an Imperial factor or unit into a metric calculation!)
then the program will spot them and even recommend appropriate corrections. Rich with clear, helpful, guiding graphics, totally
'dynamically error trapped', fast menu and icon driven wherever possible. MISTRAL software is
both intuitive and a pleasure to use.

All programs have built-in 'intelligent logic' whereby they will not ask unnecessary questions. Programs even propose solutions whilst running by anticipating what you need to do next! No need for refrigeration manuals and tables; all the factors and data needed are already built in. The collection of books and manuals alone containing this data would cost many times more than the programs. Presentation quality printed reports, essential these days for securing orders, are automatically produced. All this takes place without inhibiting the seasoned engineer or daunting the novice. But just because MISTRAL's superior programs are the easiest and fastest to operate does not limit their usefulness. These are the most complete, powerful and professional programs you will ever find for the job - anywhere!
