ADDITIONAL
INFORMATION
KCPL
is a leading manufacturer of innovative
state-of-the-art pollution control products.
Our design and engineering specialist are
ready to work for you – helping you to meet
the challenges. With years of engineering
and sales experience we are continually
looking for new and better ways to deal
with the increasingly complex Air and Environment
Control problems.
Komal’s Ventilation
systems are designed on the basis of 2 premise.
The control of atmospheric contamination
is possible through general or dilution,
and local exhaust ventilation (LEV) to provide
a safe, healthy environment for employees,
and to protect them against potentially
toxic and irritating airborne contaminants
generated in the work place. Our ventilation
systems limit worker exposure to within
the maximum permissible exposure limits
(PEL) mandated by your local Air pollution
authorities, or to within the guideline
threshold limit values (TLV). Air discharge
limitations have become stricter in the
last few years due to increasing air concern
about the effects of air pollution.
The former
type (i.e. general) (see Fig 1) functions
by causing sufficient air to pass through
the room or shop to dilute the contaminant
or contaminated air entering the space under
consideration from outside. Thus windows
fans, roof fans, central ventilating systems,
etc., accomplish general ventilation.

behaves as a mixing chamber.
Komal’s
Local exhaust ventilation (LEV) systems
(see Fig 2), on the other hand, functions
by capturing the contaminant or grossly
contaminated air as close to its source
or point of release as possible and conveying
it to the outside either directly or after
passing through air pollution control devices
where necessary. Local exhaust is a must
if the amount of contaminant escaping is
considerable, to prevent the creation of
a health hazard. Slot-type exhaust hoods
at tanks, and canopy type hoods above tanks
are examples of local exhaust hoods. If
the concentration of the contaminant in
the air exhausted is much greater than in
the general room air, the ventilation is
local exhaust. Many plating and metal-finishing
shops have a number of different open surface
tank processes that require exhaust ventilation.
Air contaminants from open surface tanks
vary in type, intensity and toxicity, depending
upon the operation. These are significant
factors when determining ventilation and
air pollution control requirements for a
facility.

(sourse) capture results in lower air contaminant
concentration in the breathing zone and
general work area.
Komal’s
Wet collectors (also called as Wet scrubbers)
are the most suitable pollution control
devices for removing acid/alkali pollutants.
In our lower end simple scrubbers, a spray
chamber scrubber (see Fig 4), water droplets
are continuously sprayed into the air stream
where water soluble contaminants are continuously
sprayed into the air stream where water
soluble contaminants are absorbed by the
droplets. The fan pulls the air through
the spray, a mist eliminator, and then release
it to atmosphere free of water soluble contaminants.
The mist eliminator traps water droplets
and mists carried by the momentum of the
air and prevents it from being released
through the stack.

Komal’s
Packed bed scrubbers (see Fig 5) are the
most efficient of the commonly used wet
collectors. They are similar to spray chamber
scrubbers but are filled with a packing
material that increases gas-liquid contact.
The air stream enters the chamber from the
bottom and the scrubbing liquid (typically
water) is sprayed onto the packing material
from the top. The scrubbing liquid trickles
downward through the packing where the air
stream passes upward through packing. The
large surface area for gas-liquid contact
makes Komal’s packed bed scrubbers highly
efficient for both water soluble gas and
mist removal.

When you choose Komal,
you can count on a fully warranted, corrosion
resistant air pollution control system,
that solves your need in a creative manner
that maximizes value at a reasonable cost,
and when your problems are solved, our relationship
has just begun. Fans, fume scrubbers, Mist
Eliminators, Hoods, Ductworks and custom
fabrications are carefully specified, manufactured
with PVC, Polypropylene, FRP and FRP composites
and installed so that you can operate efficiently.
For the equipments, we use the best type
of input materials, so that the exhaust
systems are the very best in terms of value,
durability, reliability and quality. In
the metal finishing industry, wet collectors
(also called wet scrubbers) are the most
suitable pollution control devices for removing
acid/alkali pollutants. Simplest scrubber
is the spray chamber scrubber. Please see
illustrations.
