CLDR-N系列 石墨烯聚能电锅炉（15-30kW）

CLDR-N Series Graphene Energy-Concentrating Electric Boiler (15-30kW Household Floor-Standing)

The CLDR-N Series household floor-standing graphene energy-concentrating electric boiler is designed for medium-to-large homes of 150-300㎡ and small commercial spaces. It adopts Jingyu Thermal Energy's independently developed graphene nano-coated film + quartz glass tube core heating technology, with power coverage of 15kW, 18kW, 20kW, 24kW, and 30kW across five levels, flexibly matching the heating needs of different areas and building types.

Compared with wall-mounted models, the floor-standing design provides larger internal space and stronger heat dissipation, resulting in more stable and quieter operation. The compact body (43×37×70cm to 46×53×80cm) can be placed in equipment rooms, storage rooms, garages, balcony corners, etc., without affecting the aesthetics of the living space.

Core Highlights

• Graphene Coating + Quartz Tube: Nano electric heating film with surface-area heating, thermal efficiency ≥99%, tube body temperature up to 700-800℃
• Complete Water-Electric Separation: Quartz glass insulator, no leakage, no scaling, fundamentally eliminating safety hazards
• Ultra-Long Lifespan: Core heating element with ultra-long lifespan of 30,000 hours, power attenuation only 8%
• Floor-Standing Design: Large internal space, excellent heat dissipation, more stable operation, longer service life
• Smart APP Control: Multi-stage timing, intelligent constant temperature, remote control, pre-start on the way home
• Six-Fold Safety Protection: Leakage / Anti-Dry-Burning / Child Lock / Anti-Freezing / Over-Temperature / Automatic Water Pump, intelligent water pump automatically empties to prevent freezing
• Silent & Energy-Saving: No mechanical noise, 20-30% energy savings, no disturbance for home or office use
• 380V Stable Voltage: Industrial-grade stable voltage output, suitable for large homes and small commercial use
