Introducing TWT750D-21HW: The All-Terrain Crawler-Type Mobile Air Compressor Built For Extreme Conditions
Sep 04, 2025
In demanding industrial applications where reliability, mobility, and power are non-negotiable, TEWATT steps forward with a game-changing solution: the TWT750D-21HW Crawler-Type Mobile Air Compressor. Engineered for unmatched performance in the toughest environments, this machine redefines what you can expect from portable compressed air.

At the heart of the TWT750D-21HW Crawler-Type lies a Volvo TAD833VE engine, a benchmark for reliability and efficiency in heavy-duty machinery. Rated at 235kW, this powerplant delivers stable power output with remarkably low fuel consumption. Its exceptional tolerance for high-altitude and extreme cold conditions ensures consistent performance where others fail, while its renowned durability translates to fewer breakdowns and reduced maintenance.
The compressor unit itself is designed for intelligence and adaptability. The screw air-end can be configured with different oil injection methods to suit specific operational demands, significantly enhancing cold-start capabilities and ensuring quick, reliable startup even in freezing temperatures.
What truly sets the TWT750D-21HW Crawler-Type apart is its integrated crawler chassis design. This isn't just an air compressor on tracks; it's a fully unified system where the compressor and customized crawler base work in perfect harmony.
The hydraulic motor-driven crawler system provides low-speed, high-torque characteristics, delivering immense traction and climbing power. It excels on steep inclines and can easily overcome obstacles like rocks and dirt mounds that would stop wheeled vehicles in their tracks.
This robust design is purpose-built for恶劣环境 (harsh environments)-unpaved roads, sand, gravel, and soft soil. It operates with confidence in places where traditional tire-axle driven compressors would struggle or get stuck.
Leak-Proof Engineered with a anti-leakage system to protect vital components from contaminants, the unit is also designed for easy transfer between job sites, making it the perfect partner for projects that constantly move forward.

Application-Specific Excellence
The TWT750D-21HW Crawler-Type , delivering 21 cubic meters per minute at 21 bar, is the ideal power source for a range of critical drilling applications:
Perfect for drilling blast holes with diameters of 90-165mm and depths up to 50m.
Provides consistent power for drilling water wells to depths of up to 200 meters.
Offers mobile, reliable air for renewable energy infrastructure projects.
