Among several types of ventilation underground infrastructure ventilation pose toughest challenges namely smoke, fume extraction, fire scenario, fresh air supply and operating costs.

“supply of fresh air via bore holes made through the ground has resulted in reducing operating cost by 1/5^th at the same time marginally reducing capital costs as well.”

Mode of air transport: Bore holes through ground, flexible ducts, spiral ducts, GI ducts (permanent installation), Concrete passage (permanent installation

Open ventilation: Jet Fans (0.5 HP to 60HP)

We have been proud supplier of underground ventilation systems for lift irrigation schemes spread across India namely GLIS-III, PRLIS-I and RLIS.
