Protect electrical equipment in hazardous areas

By Chemical Engineering |

Best Purging Systems

The Model YZ102 (photo) is a purge unit designed to protect electrical equipment in Class I hazardous areas. The unit applies Type Y and Z pressurizations, and when connected to a supply of protective gas, and utilized in conjunction with a Model PV-2 spark-arresting purge vent, the Model YZ102 will supply, regulate and monitor the protective-gas supply to a protected electrical enclosure and accomplish purging of the protected enclosure in an expedited manner. Type Z applications reduce the hazardous-area rating inside the enclosure from Division 2/Zone 2 to Unclassified. This allows general-purpose equipment to operate in Division 2/Zone 2 areas. Type Y applications reduce the hazardous-area rating inside the enclosure from Division 1/Zone 1 to Division 2/Zone 2. This allows Division 2/Zone 2 equipment to operate in Division 1/Zone 1 Hazardous Areas. Model YZ102 highlights include: a maximum enclosure volume of 15 ft 3; three mounting options; an operating temperature range of –20 to 120°F; and a unit supply pressure of 80 to 125 psi. — Best Purging Systems Corp., La Marque, Tex.
