Dairymaster Swiftcool Tank Coolcontrol I-0 PCB The Dairymaster Swiftcool Tank Coolcontrol I-0 PCB is a replacement control circuit board designed for use within Dairymaster Swiftcool milk cooling tanks . This PCB plays a key role in managing cooling system inputs and outputs, supporting reliable operation and accurate temperature control of the tank. Control PCBs operate continuously and are exposed to electrical load, temperature variation, and environmental conditions within the tank housing. Over time, components can fail or degrade, leading to cooling faults or inconsistent system behaviour. Replacing the PCB helps restore correct control function and ensures dependable tank performance. The Dairymaster Swiftcool Tank Coolcontrol I-0 PCB is manufactured to suit compatible Swiftcool tank models, providing accurate fitment when installed correctly. It is supplied ready for installation and uses a 5A 20mm fuse , helping protect the control circuit from overload and electrical faults. Maintaining a fully functional control board is essential for consistent milk cooling, energy efficiency, and protection of other electrical components within the system. This PCB is ideal for routine
