Watson McDaniel PTRP-91 & PTRP-94 Series — Temperature Pilots for HD Regulators
The PTRP Temperature Pilot is used with Watson McDaniel HD Regulators to control temperature in steam and process heating systems. It maintains precise temperature control for equipment such as oil heaters, ovens, process heaters, dryers, and jacketed kettles. The PTRP provides faster response and can regulate lower temperature ranges than standard PT Pilots.
