Where required, any tubing can be protected from frost with foam insulating pipe
covers. These can be supplied upon request at additional cost or sourced locally from a
hardware store.
To protect any required pressure transducers from frost, Sentinel 2 has the option of
being supplied with external transducers, rather than internal transducers. This
removes the possibility of the column of water within the pressure hoses connecting to
the internal transducers of the controller from freezing and potentially becoming
damaged, if left unprotected in harsh conditions.
