Type C2: Standard Terminal Box (on flat pad)
Type C2 is an individual terminal box for protecting the terminals on each Cast-In Band Heater half and on many other Cast-In Heater designs with one set of heater terminals.
The C2 box design requires a flat pad on half-round castings or a flat surface on other casting designs for mounting. It is made from heavy gauge, rust-resistant sheet metal. The cover is removable for easy access to terminals. The box has two 7/8″ diameter knockouts opposite each other for standard 1/2″ BX connectors.
Type EP: Explosion & Moisture Resistant Box
Cast iron explosion and moisture resistant boxes should be used in areas where the surrounding air may become contaminated with combustible gases or a high humidity level may exist. Installation requires one box per Cast-In Heater half and they are brazed to the tubular heater. The standard box has one 1/2″ NPT hub.
Type MPR: Moisture Resistant Box
This design has a moisture resistant die cast aluminum box with a non-removable polyurethane gasket in the lid. Lid is secured with captive stainless steel screws. Body and lid are painted in basic industrial gray; interior contains copper ground screw. Box is mounted to a plate that is brazed to the element. Available in a wide variety of sizes.
Type MR1: Moisture Resistant Box with Shield
This design incorporates the MPR housing style along with a perforated tube shielding unheated extensions of the tubular heating elements. This feature provides mechanical strength to the element extension and prevents overheating of the terminals, reducing possible premature failure from corrosion and oxidation.
None
This Cast-In will not have Terminal Protection.
Additional Options
125 RMS Standard
RMS Surface Finish as defined in ASME B46.1 — RMS is the root mean square of the profile height deviations from the mean line, recorded within the evaluation length. The standard surface finish for the machined surface of Tempco cast-in heaters is 125 RMS.
Special Features
Electroless Nickel-Plated — A plating technique (without using an electric current) used to deposit a coating of nickel on a substrate to prevent corrosion, wear and also as a protective coating.
Teflon Coating — Teflon is non-reactive so it is often used in containers and pipework for reactive and corrosive chemicals.
Hard coat anodizing — Anodizing increases resistance to corrosion and wear.
Magnaplate — Strong wear and corrosion resistance non-stick coating that withstands high temperatures.
