Temperature Regulators - Spirax Sarco

1 Temperature RegulatorsTemperature regulation to maximizesteam system efficiencyPilot Operated TemperatureRegulatorsThe Spirax Sarco range of Pilot OperatedTemperature Regulators have beendeveloped for close control of processtemperature applications where steam is thechosen energy fluid. An important feature inthe Spirax Sarco pilot operated range oftemperature Regulators is the ability tointerchange or combine two or more pilots onthe same regulator body. This unique featurepermits, for example, remote on/off controltogether with Temperature control. Thesevariations are available factory fitted but caneasily be added on acting Regulators , the simplest and mostThe rising cost of fuels heightens the need tocontrol the production and use of heat moreclosely and effectively. To provide the righttemperature for a process, to optimize energyusage, to provide comfort conditions, and forsafety, automatic Temperature control Sarco offers a complete line ofTemperature Regulators .
