 Air
Steam heater
Steam heaters or
steam coils are heat exchangers in which one
medium is steam being condensed while
the other medium is a gas (air) being heated when forced through the heat
exchanger with a fan. The inlet air may be ducted or simply gathered
from the room in which the steam heating unit is positioned. The
actual heat exchanger is constructed as a matrix of tubes (normally
copper) and corrugated or flat fins (aluminium, copper or other materials)
with as high thermal conductivity as feasible for the given
application.
We
supply high
quality steam heater units, purpose-specified for especially harsh and corrosive
environments.
Safe
heating of space containing combustible or
explosive gases
No
air movement mechanism can ever be totally "explosion
proof". Random sparks and static discharge are
naturally occurring phenomenon which may occur anywhere (even
in the earth's atmosphere as lightning).
However, the use of steam coil heating represent an
excellent way of room and air heating in a combustible or
hazardous environment, provided the correct safety measures
are taken as far as the fan motor insulation class, explosion
proof thermostats, etc.
The
steam heater units are particularly useful for heating of rooms or space
which may contain combustible or
explosive gases. Large amounts of thermal energy can
safely be introduced to the air without additional risk of ignition caused by
electric sparks.
Constructed
from Corrosion Resistant Materials
 Particular
attention has been paid to corrosion protection of all surfaces of the
steamheater unit by
galvanizing or epoxy coating of exposed steel. Where coating is not desirable
corrosion prone materials have been substituted by other
materials, e.g. copper
(heating coil/fins) and glass reinforced polypropylene (fan blades).
However we can also supply tinned or coated fins. The louvers
and enclosures for the steamheater are made of e.g. galvanized, enameled
or epoxy-coated steel or polypropylene, copper or brass.
Design Supply
Our steam blower
heating units are manufactured to customer specification and the dimensions are calculated
in accordance with your heating requirements, available space and the quantities
and pressure of steam, air flow, etc. The units can be connected to
ventilation air ducting.
Arrangements
Steam
heater coils can either have horizontal tubes or vertical
tubes. Horizontal tubes have slightly sloping tubes
to allow natural condensation drainage. The vertical
tubes allow easier drainage and more effective prevention of
water hammer.
