                       Our natural ventilation and light systems are ideally suited to the leisure
                       sector where a fresh air supply is essential or bright illumination of large
                       spaces is required.
                       Our flue and chimney systems are also ideal to handle any exhaust
                       requirements demanded by the large boilers often used in leisure centres.
                       Popular applications include gymnasiums, sports halls and health clubs.

Natural ventilation and lighting is a very popular solution in the health
care sector in hospitals, nursing homes and other institutions. Providing
fresh, breathable air and natural light for patients and health care workers
has numerous benefits to health, recovery and staff productivity.
Similarly, our kitchen canopies offer a safe, hygienic working environment
where food can be prepared quickly and efficiently without the worry of
external contamination.

                                                                             We serve

Our complete product range is ideally suited to applications
throughout the commercial sector. Increasingly, office buildings are
benefitting from new, greener, more efficient technologies such as
natural ventilation, natural lighting, heat pumps, solar pv and our
energy-saving air conditioning units.
Our range of exhaust products, from flues and chimneys to kitchen
extract canopies, are also suitable for commercial installation.

Our product range is perfect for the educational sector. We have found
schools and colleges are often keen to utilise the latest green and eco
technology, not just to lower costs but to act as a living experiment for
pupils and parents to experience.
Our natural ventilation systems are a great solution for classrooms
and the daylight supply from our natural lighting products are ideally
suited for the daily periods of occupation.
The growing use of heat pumps and solar pv technology to generate
hot water and electricity while reducing a buildings carbon footprint
are also widely employed as part of a whole building strategy.
Our flue and chimney exhaust systems are also suited to the
buildings heating demands and kitchen canopies can be installed
where on-site cooking or food preparation facilities are used.

                          Environmental Policy Statement

                                                                                                    ENVIRONMENTAL POLICY
It is the organisation’s objective to operate with, and to maintain good relations with all
regulatory bodies.

It is the organisation’s declared policy to carry out all measures reasonably practicable to
facilitate the ability to continually improve environmental performance.

We will establish a management structure, which ensures effective environmental
management and provide training and education to our employees at all levels, in order that
they develop a sense of awareness and responsibility for the environment. The impact or our
activities on the local environment will be assessed, monitored and controlled as required.

All aspects of this policy will be communicated to employees, clients, the public and other
interested parties as appropriate.

In line with these principles, it is the policy of members of Airtherm Engineering Limited to:

• Assess and regularly re-assess the environmental effects of the organisation’s equipment
  and operations.
• Improve the efficiency of energy use in our buildings and processes.
• Reduce the generation of waste. Use recycled materials where practical, re-cycle or dispose
  of in-house waste safely.
• Adhere to all relevant regulations concerning waste and environmental well-being.
• Ensure that all sub-contractor operations are in line with this policy, and that they are
  aware of their respective responsibilities in the environment.
• Train all employees in environmental issues.
• Reduce and/or limit the production of pollutants to water, land and air. All waste is
  disposed of under controlled conditions if re-cycling and/or the re-use of the materials is not
  an available option.
• Take environmental considerations into account when selecting our material, suppliers and
• Control noise emissions from operations.
• Minimise risk to the general public and employees from organisation operations and

We check our activities periodically to ensure they are consistent with these principles. This
policy is communicated to all employees, suppliers and sub-contractors and is made available
to the public.

      Natural Ventilation

                        High Capacity - Our natural ventilation terminals are perfect for
                        both natural, passive and solar powered options, with all four
                        sides possessing a guaranteed 50% free area allowing a more
                        efficient operation.

                        High Performance - With the addition of internal vertical
                        channels and integrated water defence, our standard terminals
                        can be converted into high performance Class A rain protection
                        (over 99% effective).

                        Internal & Trunk – Housed inside the terminal is a full height
                        divider which keeps fresh and stale air separate. Both the
                        terminal base and ductwork below are lined using a Class ‘O’
                        type 12.5mmTHK acoustic foam. The foam offers an ideal
                        acoustic characteristics and the necessary fire performance.
                        Additional acoustic layers can be applied to conform to any
                        design criteria required. The roof lid is also acoustically lined to
                        prevent unwanted noise transfer from heavy rain droplets, which
                        can be amplified into the occupied space below. This method
                        also avoids condensation forming on the underside of the roof
                        with cold air entering the terminal and hot stale air rising from

“The W-Vent (natural ventilation) system offers a cool, fresh, cost-
effective alternative solution to traditional air conditioning, it is
regulated by our advanced intelligent control panel, all day every day"
Cost Savings
The system is powered primarily by aerodynamic forces and so the only power required is to run the
low voltage controller unit. This offers substantial costs savings compared to traditional mechanical
ventilation systems that can potentially run into tens of thousands of pounds each year.
Health Benefits
By its very nature, the W-Vent (wind ventilator), S-Vent, (solar-ventilator) P-Vent (passive ventilator)
L-Vent (combined wind & light ventilator) and our X-Vent (cross wall ventilation) systems all offer a
natural solution to health problems commonly associated with mechanical air conditioning units.
Rather than re-circulating stale air (and possibly germs), the natural ventilation system is continually
removing stale air and replacing it with a fresh supply. The system takes air from the roof level
eliminating a proportion of pollution, including hazardous carbon monoxide from roadside traffic that
is a common issue with low level ventilation methods.
Suitable Applications
Our Natural Ventilation products are suitable for many applications including schools, offices and
hospitals. They are also used in private, local authority and commercial premises including
gymnasiums, colleges, universities, reception areas, store rooms, changing rooms, libraries, meeting
halls and are also suitable for specialist applications. They provide an ideal solution for delivering a
'fresh' air supply to areas where conventional room ventilation is difficult due to critical noise issues.
The Ideal Solution
Our Natural Ventilation systems offer architects and consulting engineers not only a natural and
environmentally-friendly solution but an acoustically efficient, economical and aesthetic answer to
ventilation needs.
Terminal Design
Our external terminals can be designed in keeping with the architectural design of the building or can
be manufactured to be of a contrasting appearance, adding and harnessing a feature aspect to the
buildings and its surroundings. Louvres are designed to ensure the maximum available free area of the
unit is utilised, whilst maintaining weather defensive integrity at all times.

"The S-Vent (solar-powered natural ventilation) system offers
additional fresh air requirements during those hot summer months,
and provides a better comfort to the every day working environment”

How It Works
The S-Vent system benefits of a passive stack and an active stack
system, similar to our W-Vent range, but with the bonus of a free
power source. Our S-Vent terminal delivers fresh air and discharges
unwanted stale air (CO²) from internal spaces, effectively eliminating
the need for traditional methods. The system incorporates a solar
powered boost-fan which provides additional 200l/s, 400l/s or 700l/s of
fresh air within the compartment below.
The photovoltaic panel collects daylight and convert this to electricity
that is regulated via the charge controller which charges the battery
pack. The battery is charged whenever there is enough available
daylight to do so and even generates power on a dull day. The S-Vent
range have been designed to supply fresh air 24 hours a day.
The low powered fans are set as standard to simply switch on/off at
maximum dampers or as an optional feature they can be speed
controlled variably in conjunction with the damper positions.

Standard Components
☼ 12v or 24v DC Power Supply.
☼ 40w or 60w solar cell.
☼ DC carbon fibre battery Pack.
☼ Power management module.
☼ Low powered DC fan unit - 200L/s, 400L/s and 700L/s
☼ iVent control systems operate with peripheral (wind, rain,
  temperature) devices to suit any and temperature application.

                                                 There are two methods that can be considered when

             The Vertical Balance ‘FlueVent’ System

The FlueVent balanced terminal works by the process of heat
& aerodynamic principles. It is designed to allow the release
of products of combustion through a twin wall flue system
housed within the roof-mounted terminal, whilst
simultaneously drawing in fresh air through high
performance louvres to ventilate the room below. By design,
the unit is able to provide high or low level ventilation
requirements in accordance with BS 6644 & the IGE.

All terminals are constructed using fully-welded 3mm THK
aluminium outer casing incorporating air ducts sized in
accordance with BS 6644 and IGE requirements.

 The standard internal twin wall flue system has a 316 grade
stainless steel fully-welded inner liner, insulated with 50mm
of high density insulation and a 304 grade stainless steel
outer casing. Terminals are available in a variety of sizes and
shapes (square, circular, rectangular, mitred or turret models
with the option of fire retardant GRP) and can be powder
coated to any BS/RAL colour. External louvres come complete
with a low resistance bird mesh guard.

Aesthetically pleasing, the FlueVent terminal provides
architects and consulting engineers with an effective and
economical solution where conventional ventilation
requirements prove difficult to achieve. Designs can be
produced to match any building structure and a three-
dimensional computer generated likeness can be provided for
approval, prior to manufacture. We are also able to supply
special designs to meet with architectural requirements.

The internal flue section of the FlueVent terminates with a
connection to receive one of our twin wall insulated flue
products and is sized to match the appliances used. The
terminal also incorporates removable outer skirts at it's base
to allow access to the roof plate.

An extended internal compartment is available complete with
internal flue and air ducts from the plant room ceiling to the
underside of the terminal.

All of our FlueVent systems are easy to install. The terminal
is designed to mount on either a builder’s curb or our factory
made upstand.
