The robust mechanical structure of the high density AlN, available from Watlow Australia , enable these heaters to exhibit exceptional mechanical stability throughout the temperature range. This makes the product especially suitable in applications where consistent part-to-part thermal contact during heating cycles is critical. Additionally, these heaters are applicable when requiring a clean, non-contaminating heat source as they are particle free, impervious to moisture and resistant to acidic attack.
