A nano STR open-frame dryer model

Legacy Equipment

STR Open-Frame Process Refrigerated Dryers

The unique nano direct expansion, dual action, shell and finned tube heat exchangers provide very low pressure drop and superior dew point performance because of the copper tube aluminum-finned design. This design incorporates both primary and secondary heat transfer surface areas, which eliminates the need for a mechanical separator. All of this translates into one of the most efficient and cost-saving products on the market, with one of the lowest pressure drops in the industry.
