damp and moldy crawl space

[ryan ryan]

I have around 1000m2 crawl space and it's damp and moldy, even with all vents/barriers open
clearly, natural airflow isn't cutting it! my brother advised me to install a dehumidifier
can anyone recommend the best crawl space dehumidifier for a space this size? I need one with strong, reliable performance

that's a large crawl space. you need a high capacity, commercial grade dehumidifier system. AprilAire or AlorAir are great for this

That size crawl space usually needs more than just a dehumidifier. Along with a commercial unit (like @Robbi3 mentioned), you should be looking at full encapsulation with a ground vapor barrier and sealing the vents, otherwise moisture will keep coming back.
