How to maximise heat transfer system uptime in winter

Preparing for winter involves more than turning the heating on and digging out your winter coat . For example , blocking drafts , covering outside taps and bleeding radiators can all make your home more efficient while reducing energy costs . Similarly , when working with heat transfer systems , manufacturers can follow some simple steps to optimise their facilities for colder weather . Here Dave Dyer , technical sales engineer at thermal fluid management specialist Global Heat Transfer shares his advice for maximising heat transfer system productivity during the winter .
Just like the cold weather can affect our homes , it can also have an impact on the components of a heat transfer system and the fluid itself . So , what can manufacturers using heat transfer fluids do to maximise uptime in the winter months ?
Keep oil under cover
To maintain uptime , businesses will often store barrels of new thermal fluid onsite to quickly top up or refill the system . Facilities managers with limited storage space may store new fluid outside , but this can shorten fluid lifespan , reducing its efficiency once it enters the system . Manufacturers should store thermal fluid indoors all year round , but this is particularly important in winter and colder conditions .
When kept outside , water or condensation can enter the barrels , even if they are sealed .
During temperature changes , thermal fluid drums , barrels and intermediate bulk containers ( IBCs ) kept outside for longer periods will expand and contract , causing a vacuum . This process syphons any water or condensation sitting on top of the container into the oil , making it unusable . The greater the temperature change , the larger the expansion and retraction , so extreme weather or freezing temperatures could be more damaging . Moving barrels under cover , ideally indoors before the winter weather comes is therefore integral to keeping operations running .
Keep pumps circulating
If thermal fluid is left in a system that is not operating , it
