Removable Insulation Covers Toronto, GTA, Ontario

Manhole Service

ManholeServiceManhole insulation typically requires special considerations due to the harsh conditions in steam distribution systems – unattended steam leaks, flooding, contamination with salt. ThermoHelp uses a unique design, which was successfully tested in the harsh conditions of hundreds of manholes, where a stainless steel sheet would corrode completely in one year. A leading North American district energy company has made this specification standard for all its steam manholes, replacing conventional permanent insulation.
