Introducing the KBP PlatinumX PRO Series — the most advanced, full-featured compact multi-wattage unit heater in the KBP family. Engineered for precision comfort, energy efficiency, and year-round versatility, it sets a new standard for performance and flexibility.
Available in 208V, 240V, 277V, and 480V, with field-convertible 1- or 3-phase configurations, the PlatinumX PRO stands apart with installation flexibility unmatched in its class — making it ideal for virtually any commercial or industrial environment.
With the new ECO PRO Controller, users gain the flexibility of an RF Wireless 7-Day Programmable Thermostat with an integrated temperature sensor. The heater monitors room conditions, detects cold spots, and automatically adjusts to maintain consistent comfort. Simply place the ECO PRO Controller on a wall or shelf to ensure the ideal temperature exactly where you need it.
The system is compatible with both wired or wireless window/door and occupancy sensors, which help reduce energy waste by setting back the temperature when a space is unoccupied or when a window or door is left open. Multiple heaters can also be paired to a single ECO PRO Controller, creating smart heating zones within a space for optimal comfort and control.
A standard provision for an optional 24V remote thermostat allows integration with a building management system (BMS). Combined with summer fan-only and thermostat timer modes, the KBP PlatinumX PRO adapts to your needs year-round.
Built for rugged performance in commercial environments, the flow-through design efficiently draws air in from the back and discharges it out the front, quickly heating large spaces. An integral fan delay continues to circulate heat during cool-down, maximizing warmth. King’s exclusive dual Pic-A-Watt® steel fin elements provide a range of wattage options, allowing the heater to be precisely tailored to any application.

Meet The ECO PRO Controller & Schedule Your Comfort Witn Ease

With the new ECO PRO Controller, users gain the flexibility of an RF Wireless 7-Day Programmable Thermostat with an integrated temperature sensor. The heater monitors room conditions, detects cold spots, and automatically adjusts to maintain consistent comfort. Simply place the ECO PRO Controller on a wall or shelf to ensure the ideal temperature exactly where you need it.
Expand Your Control With Optional Window/Door & Occupancy Sensors

Compatible with both optional wired or wireless window/door and occupancy sensors, reducing energy waste by setting back the temperature when a space is unoccupied or when a window or door is left open. Multiple heaters can also be paired to a single ECO PRO Controller, creating smart heating zones within a space for optimal comfort and control.
BMS Compatability Means Seamless Integration With Your Building

KBP PlatinumX Pro provides a standard provision for connecting an optional 24V thermostat. This allows integration with Nest, other smart thermostats, or a building management system (BMS), giving users remote temperature control, automated scheduling, and energy savings. Whether managing a single garage or an entire facility, the 24V circuit makes it easy to monitor and adjust comfort settings from anywhere, while maintaining precise, energy-efficient operation.
Safe Comfort For Large Spaces

Patented Smart Limit Protection (U.S. Patent #6,748,163 B2) automatically shuts power off to the heater in an abnormal event and must be manually reset for safety.

Engineering Specs
Contractor shall supply and install KB Platinum X PRO Series unit heaters manufactured by King Electrical Mfg. Company. Heaters shall be of the wattage and voltage as indicated on the plans.
Construction: All exterior and interior metal enclosure parts are made from 20 gauge electrogalvanized Steel with a rust inhibiting baked enamel finish. Smooth rounded corners and protective edge trim give an attractive modern appearance.
PlatinumX Electronic Thermostat Control: Thermostat Temperature Range: 40℉ to 95℉. Up, down temperature mode. Start/Stop. Standard on all heaters.
ECO2S+ Remote Temperature Sensor: Wireless remote temperature sensing for balanced heating at the coldest spot in the room. 2.4G wireless protocol. Includes remote temperature sensor and wall mounting bracket. AA Battery Powered.
Provision For 24V Remote Thermostat: Includes terminals to connect an optional 24V 2-Stage Thermostat. Compatible with NEST / any 24V WIFI Stat or for integration with a building managerment system (BMS).
Auto Memory Feature: Returns Unit To Last Settings After Power Outage
Adjustable Outlet Louver: Louvers direct air up or down as needed for the heating application.
Rear Intake Screen: Heavy gauge steel screen protects against foreign objects making accidental contact with the rotating fan blade.
Spiral Fin Elements: The metal sheath element is copper brazed with spiral fins 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.
Totally Enclosed Fan Motor: Permanently lubricated long life, unit bearing with 20cc of oil. Epoxy-coated motor with enclosed rotor resists moisture and corrosion for long-lasting, trouble-free operation.
Aluminum Fan Blade: Axial flow-type fan mounted directly to the motor shaft for maximum efficiency.
Thermal Overload: Heaters shall be equipped with King’s patented thermal overload Smart Limit Protection®, which disconnects elements and motor in
the event normal operating temperatures are exceeded. If thermal overload trips due to abnormal operating temperatures, thermal overload shall remain open until manually reset by turning the heater off for 15 minutes. Automatically reset of thermal overloads, which allow the element to continue to cycle under abnormal conditions, will not be accepted.
Internal Controls: Magnetic contactors are standard on all 480V heaters, all 208V/1-Phase, 240V/1-Phase, 277V/1-Phase heaters above 6kW, and all 3-Phase heaters.
Fusing: Internal circuit fusing is provided when the heater ampacity exceeds 48 Amps to comply with N.E.C. standards. A fan delay is provided standard on models 12.5-kW and above to dissipate residual heat from the heating elements.
Easy Installation: A quick access panel located on the bottom of the heater allows for quick wiring and easy maintenance for the life of the heater. Includes universal wall/ceiling bracket for simple installation.
