Terminal Connection Mica Nozzle Heaters above 40mm will have SS 304 Terminal Box with 500mm long terminal wire, unless specified Electric Terminal Connections for Mica Nozzle Heaters above 40mm dia will be provided with SS protection caps at center of width either at 180 Deg opposite the Clamping or 90 deg from Clamping, unless specified Nozzle Heaters below 40mm Dia will NOT have Protection Caps for Terminals, but have Direct cable terminal exit through edges on both sides of gap All Thermocouple Holes for Mica Nozzle Heaters (if required) will be provided at center of width either at 180 Deg opposite the Clamping or 90 deg from Clamping, unless specified along with drawing All Mica Nozzle Heaters Below 60mm Dia will not have Screw Post Terminals
Thermocouple Holes Normally required for clearance of the thermocouple probes or holding bolts. Oversize gap can in many cases serve the same purpose, using the centre of the gap as a starting point, specify location in terms of degrees and size of the hole. Minimum of ½” is required from the hole to the edge of the heater. For critical holes please provide detailed drawing. Note: As far as possible please avoid thermocouple holes. Try and locate them in the heater gap, since holes in the heater body complicates the internal wiring resulting in less heating area and also turns out to be more expensive. All Thermocouple Holes for Mica Nozzle Heaters (if required) will be provided at center of width either at 180 Deg opposite the Clamping or 90 deg from Clamping, unless specified along with drawing.
