SS Series: Unfired Steam Generator

The SS Series of  Unfired Steam Generators (USG) from DHT provide engineers and facility professionals with superior performance in commercial and institutional applications. Designed with high-quality materials, USG vessels meet ASME standards and generate clean steam, making them well suited for sterilized environments such as hospitals, medical centers, and pharmaceutical laboratories. Shell side maximum allowable working pressure is 50 PSIG for generating steam up to 45 PSIG, and 150 PSIG for generating steam up to 135 PSIG.

Installation is simple, as all components are mounted and pre-piped prior to shipment, requiring only connections to services. A microprocessor-based control panel featuring the DHT 700 Series Controller makes operation easy. Numerous options, including alarm bells, remote control, and vacuum breakers, are available.
