Tyfocor LS is made by Tyforop Chemie GmbH, in Hamburg Germany.
TYFOCOR®LS is a liquid based on an aqueous solution of physiologically unobjectionable propylene glycol with a faint odour. The fluid was developed especially for use in solar thermal systems with high thermal loads (vacuum tube collectors).
The corrosion inhibitors contained
in the product reliably protect the metals normally used in solar
technology even in mixed installations against corrosion, ageing and
deposits over long periods of time. It keeps the surfaces of heat
exchangers clean, and thus ensures consistently high thermal
efficiency of the solar thermal system.
