new way to intelligent central air conditioning is called

FAN WALL. In this modern technology, several (usually at least

four) small fan units are connected in parallel in one housing

instead of using one large fan. This arrangement has considerable

advantages. On the one hand, the modular principle increases

flexibility. Depending on the installation requirements, the

number and size of fans can be selected optimally. On the

other hand, it improves the air flow distribution: The result is

a better heat transmission and filter utilisation in the central

air conditioning unit.

Operational reliability: No total failure in case of malfunction

Using several small fans in place of one large fan improves

depending on the installation requirements: In the event of a

malfunctioning fan there is no total system failure and not even

a drop in performance because, with the appropriate design,

the speed of the other fans can be increased to compensate the non-operational fan.

Advantages of Fan wall: That added plus

• More operational reliability

• More performance

• More costs saved

• More installation flexibility

• More energy saved

• More maintenance friendliness

• … the only less: Weight and space requirement!





The new thermal break system guarantees a high thermal insulation thanks to the use of special shaped polyamide bars of 20 mm length. One of the peculiarities of this system is the half omega profile that allows the union of two or more units ensuring the thermal bridging between them. The “panel stop” profiles hold the panels without the use of screws.The use of a patented gasket system ensures smooth internal surfaces - so the AHU can be sanitisable - and a perfect airtighthness inside the unit. Moreover, the interior of the frame has been

designed with a radius shape and nylon rounded corners in order to facilitate the maintenance of cleanliness inside the unit. To improve the mechanical and air tightness properties of the frame, the nylon and omega joint corner have special grooves for screws that fasten together the aluminium profile with the plastic components. Furthermore, the screws are hidden by nylon caps that prevent the formation of dust and dirt near the head of the screw.

Single and Multi stage Air Washer

Ventaire’s Indirect/Direct Evaporative Cooling unit is a complete packaged unit for two stage cooling and ventilation applications. The basic Indirect / Direct Evaporative cooling Unit consists of an Indirect cooling section, media type evaporative cooler section, supply air blower section, and other sections, such as filters section, air mixing boxes, access section, evaporator cooling coil section, full economizer section offered to customize IDC’s functions needed.

Indirect cooling section consists of a PVC tube type air to air heat exchanger, comes complete with 304 stainless steel casing and sump, water distribution system with moisture eliminators, with submersible or end suction type pump, secondary air intake filters and secondary air exhaust propeller type fans.

Direct evaporative coolers are manufactured with 304 stainless steel casings and sumps to prevent corrosion and are supplied with submersible or end suction pumps, with water distribution header, adjustable valves and bleed-off valve. Coolers utilize 12” deep CELdek or GLASdek media, as manufactured by Munters Corporation or equivalent make.



The units can incorporate return air section, air mixing section and economizer section. Each section is also equipped with air intake dampers, and flat or v-bank air filters.

Features common to all units are structural steel channel base, galvanized steel housing, access doors, high density fiberglass insulation, high efficiency blower motors, and externally mounted and wired electrical enclosures.

Ventaire’s standard Indirect/Direct evaporative cooling Units range from 2,000 cfm to 30,000 cfm. and special units could be built up to 60,000 cfm. In contrast to standard commercial units ventaire’s each unit is custom designed to meet the particular application and specific requirements of the project.



Variable Air Volume Diffusers

Our thermally & electronically powered VAV diffusers significantly reduce the need for VAV boxes and their associated labor and component costs.

Vari-Flow, variable air volume (VAV) diffusers, are a proven method to increase individual comfort while reducing air conditioning energy & operating costs.

Thermal Products Corporation, Mfg. of Thermally & electronically actuated VAV diffusers - Tucson, Arizona. No over cooling of multiple areas to keep one person comfortable. Each Vari-Flow VAV diffuser is a separate zone of control.

Greater individual comfort, less installation, operating and energy cost is why Vari-Flow VAV diffusers make sense.

"Electra-Flow Series" (EFS) diffusers

The "Electra-Flow Series" (EFS) diffusers were

developed to compliment the (VFS) thermally

powered diffusers. The purpose of the diffuser is to

provide a wide range of installation flexibility,

accuracy of electronic control, and the comfort of

individual room zone control. The diffuser uses a

sleeve damper unique to "Vari-Flow" products to

provide high levels of secondary room air induction

with a minimum of primary air volume. This is

accomplished by varying the discharge area of the

diffuser. As the discharge area is reduced, the

discharge velocity is increased to maintain a

constant level of secondary air induction. This, in

conjunction with the horizontal primary air

discharge pattern, prevents "dumping."

The efficiency of the air distribution is proven by

applying the diffuser to exposed duct. In this

application, the diffuser will maintain a horizontal

air flow pattern over the entire spectrum of air

volume from full flow to close off. The efficient use

of primary air energy sustains secondary air

movement to minimize stratification and maintain

comfortable levels of room ventilation with

minimum amount of primary air flow.

The EFS24 is powered by a unique "thermal motor"

that proportionately operates the damper. The

"thermal motor" operates without motor windings,

stators, armatures or bearings. This distinctive

power source operates on the simple, basic principal

of thermal expansion when a substance changes

state, in this case from a liquid to a solid. The

thermal motor has a proven history of reliability and

long life.

desiccant air dehumidifiers

DFRA Description

The foolproof operation of our DFRA series dehumidifiers is based on

the principle of two continuous and simultaneous airflows running in

opposite directions through the desiccant rotor: the process airflow

(airflow requiring dehumidification) and the reactivation airflow for the

desiccant rotor (wet air).After filtration, the process airflow passes

through the desiccant rotor, which adsorbs most of the water vapour

contained in the air stream.

This is then expelled from the dehumidifier via a fan, in the form of dry

air for supply to the process ventilation system or direct to the space

in question. The reactivation airflow for the desiccant rotor is drawn

from outside, filtered and heated by electricity/steam/thermal oil, or

via a direct combustion natural gas burner. When it has reached the

temperature required to carry over the molecules of water vapour

retained in the rotor, this wet air is extracted from the dehumidifier

by a fan and expelled to the outside. Our dehumidifiers are specially

designed for easy installation, stable and continuous operation with

minimum maintenance.

The effective dehumidification of the process airflow is achieved

by the high efficiency of the desiccant silica gel rotor which

adsorbs molecules of water vapour, maintaining its performance

even at low levels of ambient humidity. The synthesized silica

gel is a chemically and thermally stable material, which is not

subject to deliquescence like other desiccant materials and

therefore provides continuous and stable performance. This silica

gel is the foundation for the long service life provided by FISAIR

dehumidifiers, as its chemical resistance plus its ability to be

washed with water, ensures its longevity. Process air humidity

values down to -20ºC Dew Point can be readily achieved, and even

more demanding level are available on request
