MISTRAL ASSOCIATES – Program Licence Price List

Buy cheap, buy twice!

If, having paid for inferior programs from one of Mistral's imitators or plagiarists that have come and gone over the years you now wish your business to benefit from the same superior programs that your successful competitors are using, then look no further!

Sorry but no, Mistral does not 'do Demos'. Mistral programs are guaranteed to perform exactly as described and our 38 year long track record for integrity and reliability speaks for us. For serious enquirers a 30 day fully operational Trial issue is available for a modest charge and which is refundable upon conversion to order.

Mistral does not increase prices to be paid by our loyal customers just to meet costs associated with creating and managing 'demos' - usually for time wasters and potential plagiarists. You are most probably neither, nonetheless please do not ask us for a 'demo'. If you care to look there is more than ample information about our products available on this 3.000+ page website.

Automatic & correctly weighted energy profiling at 30 minute intervals for every day of the year. Large product database and many new features including:- pitched roof option; in-situ sprayed foam polyurethane insulation; refrigerated containers, trucks and vans; blast freezers and blast chillers; 'context sensitive' help pages; 'cue' cards; bar graphs and pie charts; conventional 'Windows system' calculation filing, file retrieval and colour printing routines; superb quality report summaries and much, much more.

Selects from tens of 1,000's of listed products, shows all viable alternatives complete with precise corrected duties - all in less than 10 seconds ! Select against 'CELLWIND', 'COLDWIND' and 'AIRWIND calculations (as appropriate) or may be run independently. Graphically displays Balance Points when all modules are installed. Also prints out electrical data and dimensions and displays photographs and wiring diagrams etc. on screen from manufacturers' own product literature. Importantly, these programs also calculate sound pressure levels for single or multiple units, (when manufacturers have supplied the necessary data) at the set site boundary distance.

6, 7, 8, 9, 10, & 11 each program - Licence £28 (34 Euros). (Not available in USA) All 6 for £45 (55 Euros)


12) 'CELLWIND Pro’ Produce accurate and thus competitive beer cellar refrigeration load calculations to brewery specifications.

Licence P.O.A.


14) 'LINEWIND’ Similar to ‘PIPEWIND’ as described below but this is the ‘junior’ version and therefore only deals with a single refrigeration load at a time.

(Includes programs 6, 7, 8, 9, 10, & 11 above).

Licence £95 (117 Euros US$134)


15) 'PIPEWIND Pro’ The not-so-simple task of sizing refrigerant pipework for complicated multi-cooler, multi-circuit ring mains made into child's play. Icon and menu driven with 'ideogram' graphics. Totally error trapped program pays for itself every time it is used - and carries on doing so, time after time after time. Automatically loads without fuss or bother the pressure enthalpy/entropy, viscosity, performance data for many of the new refrigerants, plus the old ones for reference purposes. Steel and copper pipe data plus length equivalence factors for bends, tees and valves etc. all automatically entered so the bare minimum of key information (system duty, temperatures and required lengths) is all that is needed to quickly and accurately display/print correct pipe diameters, pressures, pressure drops and mass flow. Facility to add new refrigerant and alternative pipe information to the program's databases. (Includes programs 6, 7, 8, 9, 10, & 11 above).

Licence £990 (1,150 Euros US$1,400)
