It is our imagination that sparks new innovations. Heinen & Hopman is all about this creative drive. We ask ourselves ‘what if?’ all the time. What if… you could monitor your HVAC system performance anyplace and at any time? What if… the system warned you when it was time for maintenance? What if… you had a self-diagnosing system that gave you exact instructions on how to operate? What if I told you that these questions have already led to a powerful new tool? Meet SPOCC, the Service Portal and Operation Control Centre, which accessible on your smartphone, laptop or computer. It can be connected and integrated with your on-board HVAC system. Within the web portal and mobile app you can select spare parts to request a quote for, check the status of your service ticket and view general documents like work reports. Usage of the HH My System Mobile App will automatically result in a Digital Ship Logbook.
