Walk-in cold room design software

We are the world’s leading supplier of design software for walk in cold rooms. Founded in 1980 to write bespoke technical software for the air movement and refrigeration industries, we now provide industry-leading software solutions for manufacturers, independent constructors and dealers of walk-in cold rooms and cold stores.

With over 30 years of industry experience, our team is well aware of the essentials (and the potential pitfalls) when it comes to specifying, manufacturing and constructing walk in cold stores. The result is ColdStore Specifier, an automated program that is simple to use, accurate and efficient.

In ColdStore Specifier, Computair has created an industry-standard process for specifying walk-in coldstores, designed to speed up important quotation response times and subsequent manufacturing lead times.
