Central Station Air Handlers Units are of a panelized
construction with all metal parts fabricated of heavy
gauge zinc coated steel. The basic coil and fan sections
are insulated to prevent heat loss and condensation formation
during cooling operation. Heavy gauge structural channel
supports in strategic areas assure years of dependable
Unit housing can be made with a variety of constructional
methods, with insulation thickness available in 25 mm
or 50 mm sizes. Insulation can be fiberglass, mineral
wool or polyurethane with varying densities Panels can
be double or single skin. Other configurations are available
coupling of adjacent sections is secured by the use of
galvanised lap connectors. Internal and external panel
walls have a smooth finish to simplify cleaning.

and special fasteners.
Air Handling Units are available in weather-proof execution
for outdoor installation.
model can be supplied with various sizes of fan to ensure
the best fan selection possible.
are centrifugal fans with casing, statically and dynamically
balanced and available with forward curved, backward curved
or aerofoil section blades. Fans are mounted on rubber-in-shear
antivibration isolators (springs isolators also available)
and have a flexible canvas connector between fan outlet
and unit casing.
research provided the technical information for precise
selection of bearings to compliment the central station
bearings used on all central station units have an average
life expectancy of 200,000 hours. These bearings are rated
in accordance with industry standards All bearings are
sealed ensuring containment of the lubricant and exclusion
are installed with belt drive on an adjustable base and
are available for most voltages on 50 or 60 Hz operation.
motors are TEFC, have class B insulation and are constructed
to IP44 (class F insulation also available).
Air Handling Units, provide a highly efficient air handling
system. Three types of coils are offered providing unequaled
flexibility in almost any comfort or industrial application.
These carefully engineered coils are designed for maximum
air-to-surface contact and offer to the industry the optimum
in heat transfer surface.
are mounted on guide rails for side removal. They are
constructed with seamless copper tubes mechanically expanded
to retain aluminium fins. Copper tubes with copper fins
are also available.
has developed circuiting methods using a nominal number
of tubes per circuit which provides more flexibility,
wider selections and unequaled performance. This concept
permits a choice of feeds and tubes per circuit regardless
of the rows deep, to best match water velocities and pressure
coils are tested to 31 bar air pressure under water and
are suitable for working pressures up to 16 bars. Coils
are available for steam, chilled water, hot water or DX
drain pan has been extended beyond the coil section providing
complete condensate drainage. Heavy gauge galvanised steel
construction, with welded corner joints provides a durable
and long lasting unit. Full insulation eliminates panel
condensation and guarantees a moisture-free unit. Drain
connections are provided on each side ensuring case of
COOLRITE has designed a mixing box which combines
exact ratios of fresh air and recirculated air by means
of an efficient operating damper system. This section
is constructed of heavy galvanised steel and fitted with
a damper system incorporating non-rust bearings. These
construction features ensure life-time reliability. Full-width
flanges are included on all inlets providing convenient
installation and an airtight seal with ductwork.

and bypass damper sections are available for either internal
or external bypass. Economical and accurate control of
heating and/or cooling is achieved with the use of a face
and bypass damper. The face and bypass dampers are multileaf
and the damper blades are interlocked providing one control
point. Construction is of a frame design, consisting of
galvanised steel angles, securely bolted and braced to
form a rigid and durable structure. The damper blades
rotate in rust-proof bearings providing a smooth-action
and requiring no lubrication. The damper sections are
generously flanged and gasketed providing ease of installation
and airtight assembly.
