This Practice describes the method of specifying Process Analyzer Shelters.

The four general types of analyzer shelters that can be specified using PIP PCSPA03D are as follows:

a. Type I - Field Mounted - An analyzer in an integral cabinet mounted on a freestanding support

b. Type II - Freely Ventilated - Typically a three-sided shelter

c. Type III - Climate Controlled - Shelter with a controlled interior that is necessary for proper operation of the analyzer system(s)

d. Type IV - Controlled for Area Classification Reduction - Shelter required to operate analyzer system(s) that are not rated for the exterior area classification of the shelter

Each analyzer shelter in a project shall have a separate PIP PCSPA03D data sheet specifically tailored for its intended analyzer complement. This data sheet can be supplied directly to a vendor for small applications or, with other supporting documentation, to companies specializing in analyzer system integration and packaging.

Purpose

This Practice provides instructions for preparing a Process Analyzer Shelter Data Sheet. If prepared in accordance with this Practice, PIP PCSPA03D can provide the complete requirements for an analyzer shelter. To assure the proper operation of an analyzer system, it may be necessary to provide appropriate environmental protection. An analyzer shelter is used for added protection if the intrinsic protection offered by an analyzer enclosure is not suitable for the working environment. Analyzer shelters are not typically considered to be occupied structures.
