Accessories and Custom Configurations
l Designed for use with E-Mitters CRB and CRC l Lightweight Extruded Aluminum Housing with
5/16-18 Mounting Bolts
l E-Mitters are Easily Replaced by Removing the Top Cover l Internal Mounting Hole Pattern Simplifies Mixing and
Matching E-Mitter Sizes and Ratings
l Space Between Reflector and Housing Wall Offers a Good
Thermal Barrier to Protect the Wiring Area
l This CRA Structural Housing can be Used with any
Manufacturer’s Standard 60 × 245 mm (2.36 x 9.64") or 60 × 122 mm (2.36 x 4.8") Heaters
l Wiring Entrance 22 mm (7⁄8") Diameter at both ends, for
13 mm (1⁄2") Trade Size Electrical Fittings
Easiest Replacement of Heaters in the Industry
E-Mitters are easily replaced by removing the top cover. Wiring entrance side covers are not affected. The heater lead wires are insulated with ceramic beads and connected to ceramic terminal blocks. Heaters can be wired to function individually or grouped into heating zones.
DANGER: Hazard of Fire. These heaters are not for use in atmospheres where flammable vapors, gases or liquids are present as defined in the National Electrical Code. Where solvents, water, etc. are being evaporated from the process it is necessary to provide substantial quantities of ventilating air to carry away all resulting vapors.

Steps to Design a Custom CRA E-Mitter
Linear Assembly from Standard Components
1) Select the Housing
2) Select the E-Mitters Series
3) Select the Reflectors
4) Select the Terminal Blocks
WARNING: Hazard of Electric Shock. Installation must be grounded to earth to avoid shock hazard. Disconnect power to installation before servicing or installing heater.
WARNING: Do not use Copper Wire to make connections inside this heater. High temperatures will oxidize copper. Use of nickel plated or nickel clad insulated copper wire is recommended. Wire insulation rating must be suitable for the ambient temperature of the wiring installation.
Standard CRK Linear Housings
Standard housings are available from as assembled stock in 0.3 m (10"), 0.51 m (20"), 0.8 m (30"),
1.02 m (40") and 1.3 m (50") lengths. Other housing lengths can be made to your requirements.
