• Warranty: 3-Year Standard Warranty.
Product Features
Fully oil-free resin-cast operation with zero emissions. Inherently flame retardant and self-extinguishing, utterly eradicating explosion hazards in highly populated public areas.
Meets Tier 2 efficiency. Copper windings drastically reduce resistance losses. The solid resin structure naturally resists moisture and dust, yielding a design lifespan of 25+ years.
Equipped with comprehensive smart protection including temp controllers and overheat alarms. The fully enclosed structure guarantees stability in complex indoor or semi-outdoor setups.
Compact design accommodates wall-mounting, floor installation, or simplified outdoor layouts without building oil pits. Features a 1.2x short-term overload capacity for peak reliability.
No oil testing or replacement required. Regular dust wiping of cooling channels and visual checks on the resin state are all that's needed, keeping O&M costs exceptionally low.
Incorporates a low-noise core and shock-absorbing mounts. Operational noise is significantly reduced by 5~8dB compared to traditional models, ideal for hospitals and schools.
