Watlow nel mondo   |   Mappa del sito  |   Ricerca nel sito : 


The EZ-ZONE® ST integrated solid state controller from Watlow® offers a complete thermal system control solution in a single package. Features include a PID temperature controller connected to a high-amperage solid state relay with the option of adding a properly sized heat sink, an over- and  under-temperature limit, a power shut-down contactor and digital communications in one complete and professionally engineered product.

Because the solid state controller system is modular and scalable, a user only pays for what is needed. Stacking the EZ-ZONE ST integrated controller into multiple configurations enables flexibility to standardize the product platform to solve a wide range of application needs.
