Nyalic® is used on heat pumps, A/C units, air handlers, refrigeration and HVAC units to protect against corrosion. Nyalic applicationson this type of equipment are typically made on units used in corrosive areas such as on boats and ships, mining areas, coastal regions and any other places that are susceptible to corrosion. Nyalic is applied to protect both the interior of units, including coils, electrical and electronic components and fins and the exterior of the cabinet.
works by forming a strong mechanical bond to a clean surface and encapsulating
that surface, thereby providing protection from airborne contaminates, such as
salt, fertilizer, urea and the like. Nyalic is simple to use, but the key to a
successful application is proper surface preparation.
single coat of Nyalic is applied in most instances. Independent testing reveals
that there is no difference in heat transfer properties on coils with a single
coat of Nyalic (5 microns DFT).
use Nyalic? Nyalic protects internal electrical and electronics and bare metal
areas and components from all types of corrosive elements, especially salt. Corrosion
and atmospheric fallout is aggressive in coastal regions, and using Nyalic can
forestall the possible early onset of corrosion to important parts that are
uncoated at the factory, components that could otherwise be liable to suffer
early failure in harsh conditions.
installed corrosion treatments can include coil treatments consisting of layers
of chromate, silicate and resins, treating steel panels with zinc and corrosion
resistant paint, coating circuit boards with silicon or a conformal coating and
treating the bases with coatings containing varying percentages of zinc,
aluminum and magnesium. While all of these treatments work to some extent,
Nyalic can be applied over all of these components to gain added protection.
Nyalic can be applied over the top of all of these treatments with the
exception of silicon.
is a recommended product for heat pumps and A/C units manufactured by such
manufacturers as Mitsubishi, Fujitsu and Toshiba. The Nyalic is applied by
dealers and installers prior to the units being installed in the field.
is applied to all accessible interior surfaces, including all electrical
terminals, electronic components and pc boards, coils, etc. Once the Nyalic is
dry, technicians reinstall the panels and coat all fasteners with Nyalic.
takes less than one 12-ounce aerosol can of Nyalic to completely coat the internals
of a 4Kw external heat pump unit. From surface prep to Nyalic application, the
total wok time is approximately 40 minutes. The unit can be reassembled
approximately 20 minutes later depending on ambient conditions.
