Year after year, the most popular model series device for boats, motorhomes and caravans.

Sapphire's larger model range consists of two heaters of the same size on top. The Safire 32Di is less powerful than these devices and has been the most popular model in the range year after year, and no wonder. In terms of power, it hits the most popular 9-11 meter cruise boat category. Of course, thanks to its low minimum power, the heater is suitable for even the smallest boat of a boater who needs a power reserve.  

For the Di-series devices, a replacement end is available on request, with which the standard 60mm outputs can be changed to either 2x75mm or 1x90mm output. In this case, old pipelines can also be utilized for re-installations. The mounting foot of the device is designed so that the heater can be removed for maintenance in a few minutes.

  • Widest power range 0.9-3.2 kW and minimum power consumption 0.4-1.2 A / 5.0-14.4 W

  • Carbon brushless fan motors, very long life and quiet, smooth running sound

  • Self-diagnostics determines the cause of the malfunction and is easily reset

  • The electronic thermostat automatically controls the required heat output steplessly

  • Intelligent motor control based on PWM switch technology.

  • Easy to use and install as well as inexpensive to maintain, even by yourself.

  • Very compact size.
