Armstrong has announced that its permanently lubricated, maintenance-free (MF) S&H circulators are now available with ECM motors and new EPDM seals.
These new enhancements make Armstrong S&H circulators as much as 20% more efficient. The S&H circulators also offer a significantly expanded temperature range.
Because the S&H MF circulators eliminate the need for oiling, they reduce maintenance requirements, saving building owners time and money.
