OTS/OTD Models—Oil-less Reciprocating Piston Systems       FEATURES AND BENEFITS Low annual maintenance cost Easy installation Low operating temperatures UL listed controls Low noise 462 (L) (2) Certified Premium warranty Electric tank drain  NEMA 4, 12 Enclosures   Isolation pads Automatic float drain Refrigerated or Desiccant air dryer Electrical disconnect Air cooled aftercooler Slide base for each motor Our simplex and duplex reciprocating piston tank mounted systems are perfect for any application where clean dry air is required. Examples of applications include manufacturing, instrumentation, pharmaceutical production, placement into nitrogen generators and in laboratories. Starter control panel and dryer options are available to modify the system for a particular application. The self-lubricating composite piston technology - standard on our reciprocating compressors, increases ring life and reduces temperature providing reliability for years to come. The dual cooling pistons reduce operating temperatures and the corrosion resistant components and coatings extend ring and valve life.
