Mounting Methods
Type MC- Mounting Collar
Plated steel mounting collars are locked in place with a set-screw and serve as an adjustable stop for through the wall mounting.
Collars are shipped in bulk unless otherwise specified.
Type LR –Locator Ring
Locator rings are permanently attached to the heater sheath and are used to limit the movement of the heater while allowing for expansion and contraction of the heater sheath.
When ordering specify location from end of sheath.
Type MF –Mounting Bracket
The 16 gauge Stainless Steel Mounting bracket is an economical way to mount the heater in non-pressurized, non liquid applications. Unless otherwise specified the bracket will be located 1/2″ (13 mm) from the edge of the heater sheath.
Custom brackets of any size, thickness and material can also be supplied to meet your requirements.
Type B –Watertight Bulkhead Fittings
Bulkhead fittings provide a leak-proof method for mounting tubular heating elements through tank walls. A gasket, plated steel washer and brass hex jam nuts are included. Specify if a stainless steel washer and jam nut are required when ordering stainless steel fittings. Standard mounting location is the threaded end of the bulkhead flush with the end of the element sheath. For other mounting locations specify distance from end of sheath to gasket surface on bulkhead. Fittings are silver brazed or TIG welded to the element, depending on fitting material and customer application. Fittings in table are the most commonly used. Special fittings can be manufactured to meet your requirements.
Specify: material, flange type, thread type and length.
