Product Description


THG140 heaters are used in enclosures which need to be prevented from humidity or which specified temperature should not be lower than minimum value. The aluminium profile design of body forms stack effect so the products release heat smoothly. The pressure clamp connectors makes the installation easier and quicker.

THGL046 compact fan heaters are used in enclosures which need to be prevented from humidity. High performance axial fan provides strong air circulation and ensures steady temperature in the enclosure, so the internal connection will be safer.
