DATA MONITORING
ENERGY IMPROVEMENTS VIA DIGITAL TWIN TECHNOLOGY
Synergy brings software to the yachting industry that opens the black box of your HVAC-R system. With our DeltaOS and RefPro+ AI software we show in real-time how the system is performing and can be improved.
DeltaOS and RefPro+ is a smart self learning AI-driven solution that redefines energy efficiency in cooling technology.

IS YOUR HVAC SYSTEM A BLACK BOX TO YOU?
The system opens the black box of the HVAC system and shows you everything you want to see. Our software builds a digital twin of the HVAC system on board on its own dashboard without interfering in the existing system.
With the digital twin of the HVAC system we can give recommendations how to optimize system performance.
AI DRIVEN ANALYTICS
RefPro+ Revolutionizes HVAC Monitoring in Yachting. Synergy The HVAC Consultancy and Delta Digital introduce RefPro+, an advanced data monitoring platform bringing unprecedented transparency to yacht HVAC systems. RefPro+ opens the black box of any HVAC system. Unlike traditional diagnostic methods, which often fail to identify the root causes of performance issues, RefPro+ leverages AI-driven analytics to continuously monitor over 1.5 million data points per day—covering the entire HVAC system, chiller units, pumps, air handlers, and other critical components. By detecting the slightest anomalies in real time, it provides deep insights into system behaviour, optimizing performance and preventing inefficiencies that would otherwise go unnoticed. Environmental fluctuations, system load variations, and operational shifts are all accounted for—without the guesswork.
The results? 10% to 35% energy savings, Significant reductions in operational costs, Lower energy waste with no compromise on performance.
RefPro+ installs seamlessly in new builds or retrofit with no disruption to onboard operations. Most setups can be completed remotely, eliminating unnecessary hardware and costly onboard visits. Beyond HVAC-R, the system extends its capabilities to main engines, batteries, water makers, and more, making it an essential tool for optimizing multiple onboard systems. With RefPro+, you’re not just monitoring—you’re mastering efficiency.

RefPro+ combines smart software with a personalized service to optimize your cooling systems. Energy savings from 10% up to over 30% are possible.
