proven permafrost prevention product
Our patented M.I. permafrost prevention cable assemblies have been used to prevent subsoil frost formation since the 1970s. When we work together you'll have our 40 years+ experience to help you design a system that meets performance expectations.
numerous voltage options
You can operate your M.I. permafrost prevention cable assembly at 12 VAC up to 480 VAC.
flexibility on the job-site
M.I. cable is annealed to remove brittleness and you will find it easy to bend the cable to fill in curved areas or move around any obstacles.
embed directly in subsoil or install inside of conduit
UL and CSA have tested and confirmed that you can safely install M.I. cable drectly in the subsoil beneath the freezer or install inside of conduit in the subsoil.
choice of dual or single conductor cable
You can use dual conductor M.I. cable when installing inside of conduit and single conductor cable when installing directly in the subsoil.
hdpe overjacket protection
The extruded high density polyethylene overjacket will physically protect your cable during installation.
no degradation
M.I. cable is made of all inorganic materials and it will not degrade.
energy efficient
According to ASHRAE and the U.S.D.O.E. electric resistance heating elements operate at near 100% effciency. This system turn on at its fully rated wattage output and is very more efficient when installed on automatic controls and customized to your precise heat output.
low maintenance
With only one moving part in the contactor panel you only have to periodically check the contactor panel and ensure the moisture sensor is clean before the start of the winter season.
