SMTP 3BT KIT
The kit includes the latest smart controller that allows for remote management.
Key Features
1. Technology and Application (Coolant Heater)
- This heater operates by integrating into the vehicle's coolant circuit. It burns diesel fuel to heat the coolant fluid. An integrated circulation pump forces this hot liquid to flow through the engine block and the cabin heater core (radiator).
-
Engine Preheating (P-HEAT): Allows for easy starting, even in freezing weather, reduces engine wear, and eliminates high-emission cold starts.
2. Fuel and Efficiency (Diesel)
-
It is designed to draw fuel directly from the main tank, allowing for continuous heating without requiring extra cans or fuel containers.
-
This heater eliminates the need to idle the engine for hours to preheat it, which results in significant fuel savings.
-
Compliance: This model is typically CARB certified and EPA SmartWay verified, positioning it as an emissions-reducing solution. Low consumption.
3. Control and Technology (Smartemp 3.0 BT)
The kit includes the SmarTemp 3.0 Bluetooth digital controller, offering premium management.

Bluetooth (BT): Provides full control of the unit via a mobile app (Android/iOS) on your smartphone. You can turn it on, turn it off, and check the status without being near the vehicle.
-
Scheduling: Allows you to set 7-day start-up timers, ensuring the engine and cabin are warm by your time of departure.
-
Diagnostics: Provides comprehensive diagnostics capabilities, displaying error codes directly on the controller or through the app.
4. Compatibility and Installation
