Factory Direct Energy Saving Electric Resistance Box Type Quenching Furnace

This energy-saving resistance quenching furnace is optimized for factories with long-time continuous heat treatment and high electricity cost pressure. The furnace wall adopts multi-layer composite high-temperature insulation cotton + refractory fiber board, greatly reducing heat conduction loss outward. Matched with low-resistance high-efficiency alloy heating rods, the overall energy consumption is cut by nearly 30% compared with ordinary standard box furnaces.

We supply this energy-saving model directly from factory without middleman markup, ideal for hardware, mold and fastener manufacturers running 24h quenching production lines to lower long-term operation costs.

Multi-layer insulation structure locks heat inside the furnace cavity, avoid heat escaping to outside environment. High-efficiency alloy heating rods convert electric energy into radiant heat with high efficiency, reduce redundant power waste. During long-time continuous heating, the stable heat preservation environment cuts repeated temperature rise power consumption, realizing long-term energy saving.
