Recommended sealing material for threaded sleeves:
-
Water / glycol heat exchangers, use Teflon tape.
In these cases, hemp cannot be used as sealing material!
Connection pipes without thread:
If the connection pipes are executed without threads, then a mechanical, force-fitting connection
(STRAUB coupling) is recommended (
). This coupling could be included optionally in the
scope of delivery from TRANE, if not, then it must be provided on site. In order to avoid a damage of
the copper pipe of the heat exchanger due to mechanical force, a ring is used to reinforce the cop-
per pipe (
