The rise in power factor and peak demand charge
penalties is driving the need for better energy
efficiency in electric heat treatment furnaces. Installing
an EPower advanced thyristor power controller
with predictive load management offers a variety
of efficiency benefits, compared to legacy analog
thyristor and variable reactance transformer (VRT)
controlled designs.
Lower energy costs
Hybrid firing modes and predictive load
management strategies offer energy saving
efficiency improvements:
• Typical power factor (PF) better than 0.9 helps
to meet the PF limits set by utility suppliers,
reducing the risk of PF penalty charges
• Predictive load management can stabilize
power demand, helping to reduce peak
demand charge penalties
• Typical energy savings ≈10%
• Typical ROI < 2 years [1]
