Engineering Specs
Contractor shall supply and install KFUH ECO2S Series high air velocity unit heaters manufactured by King Electrical Mfg. Company. Heaters shall be of the wattage and voltage as indicated on the plans.
Transformer: Each unit is equipped with a heavy duty low voltage (24 Volt) transformer for the thermostat control circuit.
Heating Elements: Quick heating, long life Ni-Chrome elements are sized to provide proper watt density for maximum heat dissipation by fan-forced air convection currents.
2-Stage Heating: 2-stage energy-saving heat output (-2S Models Only) when paired with a 2-stage 24V thermostat (purchased separately).
Terminal Block: For single strike field wiring.
Low Voltage Terminal Block: For 24 Volt control.
Air Filter: Convenient access for replacement of standard 16” x 20” x 1” filter.
Motor: Energy Saving, Long life, thermally protected, permanently lubricated, direct drive ECM motor (no belts to adjust or slip). This low noise, 5 speed motor is designated for use with air conditioning capability as well as heating. Very quiet operating. 60 second fan delay.
Overcurrent Protection: 208 & 240 volt KFUH Endura Pro models have 60 amp circuit breakers with single strike terminal block. 480 volt models have single
strike terminal block. Units over 48 amps have 60 amp fusing.
Limit Control: Integral automatic high temperature limit control in each heating element bank prevents the delivery of air at unsafe temperatures. 20-35 kW use a manual reset limit control to completely shut the unit heater off should over temperature occur.
Fan Relay: Heavy duty fan relay standard with summer fan operation.
Diffuser: Various styles available and must be ordered separately.
Approvals: cULus Certified for US & Canada
