Why This System
Vietnam has a split climate - the north experiences seasonal variation including a cooler, drier winter; the south is consistently tropical year-round. Cleaning schedules should reflect local climate, not a single national standard. TOSTEM Vietnam products carry Japanese quality standards - better hardware specification and manufacturing tolerance than locally-produced Vietnamese aluminium. Maintenance returns more value on these products.
