WHD-RQ350-XP Fuser Thermostatic Controller

The WHD-RQ350-XP thermostatic controller is designed specifically for hot melt adhesive machines, providing precise temperature management and ensuring reliable pipe welding. It features a digital display, user-friendly operation, and built-in safety features, ensuring stable operation even in harsh environments, providing efficient and safe support for professional plumbing and construction applications.
Precise Temperature Control: Utilizing advanced control algorithms and high-precision temperature sensors, the hot melt unit circuit board maintains temperature control within a very tight tolerance, meeting the precise temperature requirements for hot melt joining of pipes of varying materials and specifications, ensuring high-quality hot melt connections.
Easy Operation: The digital display and push-button operation make temperature settings and operating status easily visible, making operation easy even for first-time users.
Safe and Reliable: Equipped with multiple protection features, including overheating and short-circuit protection, the unit reacts quickly to abnormal conditions such as overheating and short-circuiting. If the hot melt unit temperature exceeds the safe range or a short circuit occurs, the circuit board responds immediately, shutting off the heating circuit and sounding an alarm to prevent equipment damage and safety incidents. Strong stability: Using high-quality electronic components and undergoing rigorous testing and screening, the circuit board can operate stably in complex working environments, reducing the probability of failure and extending the service life of the fuser.
