Electrical & Critical Infrastructure
Short shutdown. No drying time. Insulation preserved.
Short shutdown. No drying time. Insulation preserved.
Electrical asset cleaning is one of the most under-served high-value applications. Switchgear, motors, transformers and substation equipment all need cleaning to maintain insulation health and cooling performance. Conventional cleaning needs a long shutdown — but shutdowns cost six figures in lost capacity. We only work on equipment your licensed electrical worker has isolated and proven de-energised, with our own lock and tag on the isolation point. Dry ice is non-conductive, non-abrasive and leaves no residue, so there's no drying time before re-energisation — the outage is shorter, not eliminated. Insulation resistance preserved (and often improves). Per-asset documentation produced for asset register. We work with utilities, large industrial sites and data centres on annual maintenance contracts.

Electrical FAQs
Can MV switchgear really be cleaned live?
No. We only blast switchgear that has been isolated and proven de-energised by a licensed electrical worker, with our own lock and tag on the isolation point. We work to your electrical authority and licensed HV operators throughout the isolation and testing process — what dry ice adds is speed inside that outage, with no drying time before re-energisation.
How much will IR improve after cleaning?
It depends how much of the leakage path was contamination rather than insulation condition, so we don't quote an expected percentage up front. We IR-test before and after and give you both readings — on your own asset, that pair is the only number worth having. Where contamination was low the reading may hold steady rather than improve, which still confirms the clean didn't degrade the asset.
How is this different from compressed air cleaning?
Compressed air relocates contamination. Dry ice removes it through thermal shock + kinetic impact + vapour expansion. IR readings improve after dry ice; not after compressed air.
What documentation do you provide?
Per-asset photo log (pre/during/post), IR test sheet, cleaning record. Suitable for asset register, delivered as PDF within 24 hours.
