High-temperature strip heaters can keep gearboxes warm in winter

Turbines in cold climates face blade icing and occasional shutdowns from it. Restarts with cold, viscous oil in the gearbox can strain the entire drivetrain. Warming the oil beforehand is now possible with several heater designs. Here’s one from Watlow along with sizing guides. Named for its 0.375 in. (9.5 mm) thickness, the rugged Watlow
