  Caldwell® Quality  



Caldwell® was formed in 1948 and for over fifty years, they've been devoting their energies exclusively to applying sound engineering, and metal working and machine craftsmanship to making only the highest quality products in drying floors, fans, and heaters. Caldwell® incorporated in 1955 and has been growing steadily ever since.

All Caldwell® fans and heaters are 100% factory stress tested - to their engineering standards.

Caldwell® manufacturing is state of the art - featuring up to the minute robotics - one of the most advanced manufacturing facilities in the agricultural industry.

Computers control critical operations - like roll forming of channel lock floors.

Not only do Caldwell® products feature more spots welds than any competitor, Caldwell welds are ground smooth for a clean functional look.

Protective screens are pre-coated with durable polyvinyl coating.

Enamel paint is applied to a thickness of a full two mils. As are galvanized coatings. The result is years of service.

Caldwell® fans feature extra large spinner hubs on the fan impeller to maximize horse power efficiency.

Every Caldwell Aluminum impeller is dynamically and electronically balanced and mounted directly to the motor. The critical tolerances that result mean better performance.
