TANK HEATERS - IMMERSION

ER Series - heaters will function when operated at lower than rated voltage, but with associated reductions in power output and efficiency
Immersion Heaters are primarily used to help maintain oil temperature to avoid cold startups in cold operating conditions
May be utilized in water or other solutions
Keeps oil at approximately 80°F
Automatic built-in fixed setting thermostat normally closes at 70°F and opens at 100°F
Will not burn oil
Weatherproof wiring enclosure (NEMA 4)
For Tanks larger than 500 gallon use multiple heaters
Heaters over 10 amps, 480 volt, or three phase must be used with a contactor
Amps = Watts/Volts for single pase
Amps = Watts/(Volts x 1.73) for three phase
Wiring Diagram included with heater
UL recognized and CSA certified
22 W/sq in power density on all ET Series heaters
Interior thermostat has a 250VAC maximum rating
CAUTION:
Heaters must be mounted horizontally
Do NOT mount from the top down
Heaters must be immersed at all times
Heaters are not rated for DC current
