All units in this table are suitable for use up to 1800°F (982°C) maximum surface temperature. For unheated units, see catalog page 430. Sinuated wire, high watt density units are provided with embedded sinuated elements and high emissivity coating unless exposed sinuated is specified when manufactured. (These are not stocked.) Contact your Watlow representative. 1 These units have dual elements to use in “parallel” for 240V usage. Alternate designs are available for 480V, 277V and three-phase (internally wired). Contact your Watlow representative.
