Rotecna 1200 hydraulic heating panels are designed to maintain a constant temperature, minimizing temperature spikes. The hydraulic panels work as heat accumulators. Three model sizes—1200 x 400, 1200 x 500 and 1200 x 600—allow for various combinations depending on the size of the pens in order to create a comfortable micro-climate for farrowing, weaning and wean to finish.
