ECO Line Equipment

CMWTEC’s ECO line battery finishing equipment bridges the gap between high-performance technology and cost-efficiency. Designed for lead-acid battery manufacturers who demand reliable, precise machines without the full investment of a Premium Line setup, our ECO Line delivers consistent quality at an optimised price point.

The ECO Line covers the essential stages of the battery finishing process: volumetric acid filling, acid levelling, post-brushing, post-greasing, plug insertion, battery washing, air leak testing, high-voltage testing, high-rate discharge testing and battery labelling. Each machine is built on the same engineering principles as our Premium Line – ensuring durability, accuracy and seamless integration into your production line.

ECO Line machines are designed for flexibility. Whether you operate a smaller battery production facility or require a cost-efficient solution for specific process steps, our ECO Line equipment adapts to your exact requirements. Individual machines can also be combined with Premium Line equipment to create a hybrid battery finishing line tailored to your needs.

Manufactured at our facility in Runkel, Germany, every ECO Line machine meets strict quality standards. CMWTEC’s ECO Line is the ideal choice for battery manufacturers seeking proven German engineering at an efficient investment level.

Frequently asked questions

How does the ECO acid levelling machine adjust the acid level?

Batteries from the conveyor of the finishing line are positioned exactly, and the levelling heads are lowered into the filling holes. Sensors in each head monitor the level in each cell individually. When the level is reached, the fill stroke rises and the battery is fed out. The next batteries are then fed into the levelling position.

How accurate is the levelling, and what capacity does it reach?

The level accuracy is ±2 mm of the final level. The machine handles automotive car and truck batteries from 20 to 70 kg at up to 6 batteries per minute, depending on level volume.

How is the machine set up for different batteries?

The heads can be adjusted to the distance of the battery cover holes, and battery heights are set via a vertical spindle movement. The machine connects to the acid supply system of the factory. Its control can be integrated into a main system using program pre-selection.

How does it differ from the Premium Line acid levelling machine?

The ECO machine combines an automatic levelling process with semiautomatic handling and reaches ±2 mm at up to 6 batteries per minute. The Premium Line Acid Levelling / Level Checking machine works with two stations, one for levelling and one for checking the level. It reaches ±1 mm at up to 8 batteries per minute.
