Abstract
Abstract THE INSULATING JACKETS PREVENT FREEZING AND RAPID TEMPERATURE FLUCTUATIONS OF INSTRUMENTS AND CONTROL EQUIPMENT, AND ARE PARTICULARLY USEFUL TO INSULATE SUCH DEVICES IN CHEMICAL PROCESS EQUIPMENT. THE JACKETS ARE FORMED FROM A MULTILAYER MATERIAL WHICH IS WEATHERPROOF, IS RESISTANT TO HEAT DAMAGE, AND HAS EXCELLENT THERMAL INSULAT- ING PROPERTIES. RELEASABLE FASTENERS FACILITATE RAPID INSTALLATION OF THE JACKETS, AND ALLOW REMOVAL OF THE JACKETS WHEN THE INSTRUMENTS REQUIRE SERVICING.
