Ordering Best Practices – How to Choose the Best Lid for Washdown Environments

Choosing the appropriate lid will ensure the Decontactor operates with maximum performance in washdown environments. Meltric Decontactors are available in either a normally open (NO) or normally closed (NC) lid option. Here are some guidelines to determine which lid option is best for you:

  • Normally Closed: The NC lid requires an operator to manually close it to obtain a complete watertight seal. It is recommended that this option should be used when an operator is less than 20 feet from the device or within easy reach. This ensures the operator can see the NC lid needs to be manually closed prior to washdown operations in order to keep the plug and receptacle dry.

  • Normally Open: If an operator is more than 20 feet from the device, as in cord drop applications, the NO lid option is recommended because at a distance it is easily seen and readily indicates that the Decontactor needs to be manually closed before washdown operations in order to keep it dry.
