The ADAPTA-CELL™ evaporative cooler by APT INDUSTRIES, INC.
is a modern economical approach to the proven concept of evaporative
today’s ever increasing energy costs, the application of evaporative
cooling equipment is experiencing phenomenal growth. ADAPTA-CELL™ utilizes an exclusive evaporative cell constructed of either an
impregnated cellulose paper or a UL approved inorganic bound glass

The ADAPTA-CELL™ is composed
of the tank, casing, evaporative
cell bank, and the recirculation system.
A small amount of recirculated water from the tank is distributed
across the length of evaporative cell bank by means of a pump discharging
into a distribution header located above the cell bank. As the water
flows down through the cells, the unique cross-fluted design of
the cell induces turbulent mixing between the water and the air
traveling across the cell bank.
Optimum heat and moisture transfer is assured due to the internal
geometry of the cell, which continually directs the water to the
air entering side of the cell. Make-up water, to replace that which
is added to the air stream, enters the tank through a float valve.
Evaporative cooling applies the well-known process of evaporating
water directly into the air stream. The water, which is constantly
recirculated, reaches equilibrium with the wet-bulb temperature
of the entering air, both becoming equal. The constant temperature
water lowers the dry-bulb temperature of the entering air so that
it approaches the water temperature. This free adiabatic cooling
is effectively used in numerous industrial applications and processes
where precise humidity control is not required.
In addition to evaporative cooling, the turbulent mixing of the
air and water yields an efficient air-cleaning situation with airborne
particles impinging on the cell surface and being washed into the
tank. This same washing action is also effective in reducing odors
by removing certain gases and vapors from the air. A constant fresh
water "bleed" into the tank assures a low concentration
of dissolved gases and solids and prevents scale formation.
for the ADAPTA-CELL™ include hot spot cooling near ovens, furnaces, and foundry casting
operations; rubber and glass manufacturing and other high heat production
areas; generator, motor and electrical equipment rooms; paint spray
booth make-up air; and engine and gas turbine intakes.
- Cooling Efficiency – 90% at face velocities approaching
500 FPM with a nominal 12" deep cell.
- Face Velocity – 750 FPM without water carryover
Evaporative Cooler Tank:
The tank provides the foundation
for the evaporative cooler components. It is constructed of seam
welded, 12" deep, 14 ga. stainless steel. The standard tank
is 12" deep and provided with a corrosion resistant coating.
Tanks may be provided in other materials such as galvanized or hot
rolled steel up to 3/16" thick.
- Evaporative coolers may be provided for installation on a concrete
tank provided by the owner.
- Tank sides may be insulated with metal skinned foam insulation.
Evaporative Cooler Casing:
The casing is mounted with gaskets onto the evaporative cooler tank
and forms the housing for the cell bank and recirculation system.
It is constructed of double wall APT-O-LITE™ form insulated
panels with an optional inspection door. Interior marine lights
facilitate examination of the cells and recirculation system.
- Other materials such as stainless steel in various gauges
may be provided.
- Casing may be constructed of double wall, insulated panels with
any combination of aluminum, galvanized steel or stainless steel
Evaporative Cell Bank:
The cell bank, covering the entire cross section of the unit housing,
is assembled from individual evaporative cells either 6, 8, or 12"
deep in the air flow direction and 12" wide. A distribution
pad is placed along the entire top of the bank to assure even distribution
of the recirculated water. Individual cells are 48" or 72"
high with taller cell banks being formed by stacking cells with
intermediate rack supports. Cell racks are fabricated from either
galvanized or stainless steel and are designed to insure correct
cell-to-cell compression to avoid air bypass or water carryover
between the cells.
The recirculation system of the ADAPTA-CELL™ consists of a vertically mounted centrifugal pump which draws water
out of the tank and discharges into a PVC distribution manifold. The
manifold extends across the top of the cell bank and distributes
water through a series of uniform orifices onto the distribution
pad which spreads water evenly over the top horizontal surface of
the cells. CLICK PIC for enlarged view of this photo.
- Discharge piping and distribution manifold may be fabricated
with copper tubing.
- Suction screens may be provided to prevent large particles from
entering the pump.
- The recirculation pump may be external to the tank.
