The "Guardians of Blue Skies" for Weijiamao — KNOW-HOW NKE90W Pure Electric Water Sprinklers Successfully Delivered

East of Jungar Banner, Ordos City, Inner Mongolia, lies a mega coal mine with an annual raw coal output of 15 million tons: North Weijiamao Coal & Power Co., Ltd. Here, water sprinklers are far more than auxiliary equipment — they serve as the "Guardians of Blue Skies". Four units of the 40m³ mine-specific all-electric water sprinkler, the KNOW-HOW NKE90W newly delivered by KNOW-HOW Group, have taken on this important mission.

The on-time delivery embodies KNOW-HOW’s corporate tenet of "A promise is worth a thousand taels of gold", and also marks Huaneng Group, a state-owned enterprise, recognizing our strength in new energy technologies.

A choice by state-owned enterprises, a testament to solid strength. The adoption of KNOW-HOW NKE90W by North Weijiamao Coal & Power Co., Ltd. means this large state-owned coal mine with an annual output of tens of millions of tons has entrusted KNOW-HOW with the important tasks of dust suppression and green mining. This move is another vote of confidence from state-owned enterprises in KNOW-HOW’s in-depth achievements in electrification.

Guardians of the Blue Sky: KNOW-HOW NKE90W All-Electric Water Sprinkler

Extra Large Capacity & Ultra-Long Endurance

Equipped with a 40m³ water tank, the vehicle can travel far more than 5 kilometers on a single full water load. Powered by a high-capacity 600kWh battery and fast-charging technology, it supports efficient continuous operation to meet the mine’s constant dust suppression demands.

Robust Power for Harsh Mine Conditions

Fitted with dual drive motors with a single-side power of 250kW. Leveraging the motor’s inherent advantage of delivering peak torque at zero speed, it runs steadily even with a full 40-ton load on slopes, easily adapting to complex mine road conditions.

Intelligent Spraying & Precise Dust Control

The tank is made of high-strength manganese steel with internal anti-rust treatment and a low water level alarm. The high-efficiency spraying system features multiple working modes, integrating high-pressure water jet and mist spray functions. It operates reliably even in extremely cold environments, effectively protecting the mine’s air quality.

Proven Solutions & Solid R&D Strength

The outstanding performance is only part of the reason why this model is favored by state-owned enterprises. More importantly, KNOW-HOW boasts well-polished and field-proven new energy solutions accumulated over years.
