• Pressure spring connectors for fast wiring
• Small, compact design
• Quiet in operation
• Dynamic heating up
• Clip fixing
Fan heater prevents formation of condensation and provides an evenly distributed interior air temperature in enclosures with electric/electronic components. The heater is connected using the internal terminal connectors. The small size of the TSS 409 makes it ideal for use in enclosures where space is at a premium.
