Sep 18, 2002 Operated by self-contained thermostatic element, TERMOVAR allows boiler temperatures to rise upon start-up by minimizing circulation through boiler until operating temperature is obtained. Minimized condensation of combustion products on fireside prevents premature corrosion of boiler and reduces possibility of thermal shock. TERMOVAR is available in sizes 1/2 to 2 in. with thermostat opening temperatures of 113, 131, 142, 162, and 176 °F.

Jun 06, 2002 PMA Model KS 40-1 controls multiple industrial burners with modulating or sequential control functions. Control can be switched from on/off of sequential burners to motorized control of modulating burners, allowing use of different fuels. It can operate burners in parallel, as positioner that follows output signal from another controller, or it can accept second temperature or pressure input as process variable for boiler drum level control applications.
