History of the company

IEP Industrieelektronik, headquartered in the town of Ried im Traunkreis in the Province of Upper Austria, has been on the market since 1986. By exchanging ideas with customers over the past few years, we have been able to develop meaningful user-specific products. This means that IEP Pölz has secured a significant position for itself in the fields of automatic battery charging for emergency vehicles or combined plug-in connections for air and electricity, reeling devices for air and energy (12-/24-volt) battery monitors or respiratory monitoring.

Safety is our business

More than 10,000 emergency vehicles and boats with thousands of plug-in connections for air and electricity are currently connected to Pölz systems. And the emergency services are more than satisfied.
