Precise Fuel Atomization: Engineered as a siphon type nozzle for optimal fuel dispersion in waste oil heating systems

To ensure reliable performance

Durable 5-foot capillary tube supports optimal bulb positioning for sensitive thermal response

relying on a thermopile/thermocouple rather than an external 24V power source

ensuring peak thermal efficiency in steam heating systems

Johnson Controls MR4PMUHV-12 Control THPU32HP7Y Precise Fuel Atomization: Engineered asThe Johnson Controls MR4PMUHV 12 is a professional grade, multi function refrigeration defrost control designed for precise temperature management in commercial walk in coolers and freezers. As a primary digital defrost timer replacement, this unit integrates four critical functions into a single HVACR control module: a high accuracy thermostat, a defrost cycle timer, a digital readout, and a defrost termination switch. It supports both electric heat
