Model: 32-SBL-TS-205P Take control of your cooling system with the all-new DeWitts #32-SBL-TS-205P Brushless Fan Temperature Sensor—designed for seamless integration with all SPAL Brushless fans and wiring. This advanced sensor ensures precise temperature management, activating your brushless fan with a soft start at 175°F, gradually increasing speed as needed. At 205°F, the fan reaches full power, delivering maximum cooling performance only when necessary. This progressive ramp-up technology reduces electrical stress, extends fan life, and optimizes cooling efficiency. Note: SPAL's brushless fans CANNOT be activated with a relay/switch setup. The brushless fans require a negative PWM signal, which you cannot get from a traditional fan relay kit. If your fan controller or ECM CANNOT provide a PWM signal, then we recommend using our wiring and #32-SBL-TS-205P temperature-activated smart sensor. Key Features: Soft Start at 175°F – Fans engage smoothly, preventing sudden surges. Intelligent Ramp Control – Adjusts fan speed dynamically for efficient cooling. Full Power at 205°F – Ensures peak cooling performance in extreme conditions. Compatible with All SPAL Brushless Fans & Wiring – Plug-and-play integration. Enhanced Durability – Reduces wear on electrical components and extends fan lifespan. Solid machined construction with 3/8” NPT thread, for easy adaptability Heat Sleeve added to body for accurate temperature and added protection Upgrade your cooling system with cutting-edge temperature control—experience the difference with the DeWitts #32-SBL-TS-205P
