Digital Transformation


Traditional heat exchangers maintenance philosophies are time-based or "preventative": assets are cleaned at specified time intervals (e.g. at turnaround) or, at best, cleaning decisions are made based on simple, potentially misleading) monitoring indicators (e.g. fouling resistance). This approach is not only sub-optimal and leaves significant economic opportunities on the table but it can also result in selecting the wrong action to take, leading to ineffective cleanings and costly remedial actions to be taken (e.g. clean again the same unit!).


At Hexxcell, we enable your digital transformation journey allowing your plant operations to move from a preventative approach to a predictive one whereby future operational issues (e.g. production loss) are detected in advance and corrective actions or optimisation opportunities and are suggested to operators. 


Even further, we enable a Prescriptive approach where we indicate not only when to take a certain cleaning action and for which heat exchanger, but also what cleaning action to take (e.g. mechanical, chemical or thermal cleaning).

At Hexxcell, we have been involved in digitalization projects at various scales


Cleaning actions are performed at regular intervals


Clean before loss in production, hitting furnace limits etc.


Select Mechanical, Chemical, Thermal, cleaning


Cleaning actions and duration are a function of the asset state
