* Spiral Steel Fin Element * Double Inlet Blower * Totally Enclosed 3R Motor * Nema 12 Construction * Steel Spiral Fin Element * Adjustable Louver Hood * Control Options * Optional Nema 4XThermostat * Optional 120 Volt Control * Optional Element Step Control * Optional Disconnect Switch * Optional Motor HP Upgrades * Optional No Diffuser Louvers * Optional Remote Fuse Panel

Construction: The heater case is fabricated from high tensile electro-galvanized steel that is welded together forming a durable uni-body cabinet. Heater is finished with a rust inhibiting epoxy coating. Adjustable Outlet Louver: Louvers direct air up or down as needed for the heating application. Intake and Discharge Screen: Heavy gauge steel screen protects against foreign objects entering the heater. A 1"x16"x20" filter is provided to prevent dirt and dust build up in the heater. Nema 12 Wiring Compartment: The wiring compartment is sealed with a ¼" Poron high density polyurethane gasket. This provides excellent protection against moisture, dust and dirt from invading the electrical components and wiring. All optional control accessories are nema 12 rated. Spiral Fin Elements: The metal sheath element is brazed with spiral fins and then molded into a coil configuration. This combination produces the best heat transfer while eliminating the potential for hot spots by positioning the element in the maximum airflow stream. Blower & Motor: Totally enclosed outdoor ball bearing fan motor. Permanently lubricated, class B insulation, auto protected, permanent split capacitor and 60 C Ambient. Large capacity dual inlet blower handles high static pressure and moves large air volume. Motor leads are enclosed in a seal tight raceway to prolong equipment life and reduce maintenance. Air Intake Temperature Control: A built-in thermostat located at the intake blower is factory set at 100 F which prevents the heater from operating when the ambient temperature exceeds this limit. This will prevent the heater from wasting energy, and is an extra measure of safety. Auto-Reset Thermal Cutout: Power is diconnected from the element if an over heated condition occurs. The fan continues to run to dissipate excess heat from the element. The element is reenergized automatically when the normal operating temperature returns. Internal Controls: Magnetic contactors are standard on all units. A transformer is provided for 24 volt control. This enables the customer to use a standard low voltage thermostat. Sub circuit fusing is provided when the heater ampacity exceeds 48 amps to comply with NEC standards. A fan delay is provided standard on models 12.5-KW and above to dissipate residual heat from the heating elements. Easy Wiring: A large wiring compartment with easy access allow for a quick installation. Listing: Heater is approved for installation in enclosed plenum areas under ETL File Number 50050. Mounting: CK heater comes with two brackets welded on top to be hung from the ceiling or beam using threaded rod.

Circuit outboard supply customer provided. Element Step Control: CK heaters can be provided with 2 stage control. Additional steps can be added for improved energy management, refer to table. Disconnect Switch: The CK is available with a 3-Pole non-fused disconnect that is door interlocking and has a padlock provision can be provided as an option. Motor HP Upgrades: Standard models are listed with motors that will provide sufficient CFM for the KW they are designed for. Where additional CFM is required a larger motor and blower can be provided. Refer to the table for available CFM/Motor combinations. No Diffuser: Used when the heater will be connected to ductwork. Remote Fuse Panel: A remote fuse panel can be provided when the heater is mounted in an inaccessible area. This allows the fuses to be located in an electrical closet where they can be serviced.
