Maintenance

1. Scheduled plant maintenance should include the draining and ﬂushing of the condensate drip legs

and sediment traps as well as inspection of condensate traps, vacuum breakers, air vents and valves.

Boiler water analysis should also be performed on a regular basis.

2. To continually deliver optimum heating capacity, both the external and internal heat transfer surfaces

must be maintained as clean and corrosion free as possible. The ﬁnned surface can be maintained

by the use and constant inspection of pre-ﬁlters. The ﬁlters should be replaced as needed.

3. Should the ﬁnned surface become fouled, the coil can be cleaned utilizing commercially available coil

cleaning ﬂuids. Caution should be exercised in selecting the cleaning solution as well as the cleaning

equipment. Improper selection can result in damage to the coil and/or health hazards. Be sure to

carefully read and follow the manufacturer’s recommendations before using any cleaning ﬂuid. Clean

the coil from the leaving air-side so that foreign material will be washed out of the coil rather than

pushed further into the coil.

4. Internal coil maintenance consists primarily of preventing scale and corrosion. This is accomplished

through aggressive boiler water treatment, removal of dissolved oxygen and the removal of non-con-

densable gasses such as carbon dioxide.

Note: Boiler water treatment is beyond the scope of this manual. Contact your local water treatment spe-

cialist for assistance in establishing a proper boiler-water treatment program.

Operation

1. Proper airﬂow distribution is vital to coil performance. Air-ﬂow anywhere on the coil face should not

vary by more than 20%.

2. Air velocities should be maintained between 200 and 1500 feet per minute.

3. Operating pressures must be at or below the maximum operating pressure for that coil at the steam

temperature. Pressure and temperature limitations can be determined through Luvata’s Pressure and

Temperature program. Contact your local Luvata coil representative for assistance.
