Cummins Generator Technologies’ STAMFORD and AvK alternators are designed, engineered and built to withstand the harshest, most extreme operating conditions in the world, whether they’re working on rigs down to -20°C in Siberia or in Saudi Arabia where temperatures can reach as high as +54°C.
You’ll find our alternators equally at home in dusty desert conditions or on offshore platforms where we provide total environmental protection, delivering the reliability and durability demanded by operators. Whatever the conditions, wherever you are, we’ll provide you with power.
