Industrial comfort control and waste-heat reuse
The printing facility reference describes technical hot-air heating and cooling, recovery of waste heat from the compressor station and control of three air-handling units. The automation scope also covers heating circuits, a VRV system, domestic hot water and zone-level supply-air regulation.
Two air-handling units were integrated through Modbus RTU. The documented system uses compact Siemens PXC controllers, Desigo Insight supervision and Symaro field devices.
