Heater Features
Incoloy® 840 sheath standard on all items except suction oil heaters-allows for the widest coverage of applications and temperatures, plus gives a margin of safety for unknown corrosives or contaminants.
High purity MgO powder compacted to provide maximum heat conductivity and optimum dielectric strength.
Type ‘A’ 80/20 resistance wire sized to provide lowest wire watt density for maximum life.
Fusion welded junction between pin/resistance wire to provide a 360″ circumferential joint, giving superior strength and life.
Recompacted bends to restore MgO density in bend areas.
Moisture sealed to prevent the entrance of contaminants during storage and service. Silicone end seals on heaters for oil, air and corrosive applications. Epoxy seals for water applications.
