GEA A-Tec Spiral Freezers Get Upgrade for Lower Frost Build-up


GEA has recently upgraded its older A-Tec spiral freezers by implementing the new Static Pressure Control System (SPEC).

The simple but useful upgrade controls the airflow, thus reducing frost build-up which increases productivity and improves product quality. Saving time, energy, money and a four-month ROI are further advantages of the new SPCS.

According to the producing company, all GEA A-Tec spiral freezers built before 2015 have a manually-operated balance fan to control internal airflow in line with changing atmospheric conditions within the production hall. A fan that is incorrectly set increases the risk of frost build-up, which leads to more defrost cycles, reduced productivity, an inconsistent product profile, and higher production costs.

Now GEA has provided an upgrade for these A-Tec models which is in line with the latest spiral freezer control technology. The internal airflow of spiral freezers is automatically controlled and minimized, which reduces frosting around the air intake. Rather than relying on the operator’s judgment, the SPCS monitors atmospheric conditions automatically using a PLC algorithm and makes the necessary adjustments to the fan speed.
