Air Distribution

Company Profile

Gilberts (Blackpool) limited is one of the UK's leading designers and manufacturers of Grilles, Diffusers, Louvres, Smoke/Fire Dampers and Natural Ventilation Systems for the Heating, Ventilating and Air Conditioning industry. Privately owned, the Company was originally established in 1960 by the owner Gil Haslam.

Company Profile

With over 50 years of industry experience the Company has evolved from modest origins as a manufacturer of Domestic Warm Air Heating Grilles to now become one of largest UK manufacturers of Commercial Air Distribution products. Following a strategy based upon organic product range growth the original domestic warm air range was initially complemented by commercial aluminium Grilles and Diffusers followed by Smoke/Fire Dampers, VAV and now more recently, as we search to develop more energy efficient solutions, Natural Ventilation.

Company Profile

Today therefore we are a true multi-product based Company with Divisions specialising in:

  • Grilles & Diffusers
  • Smoke, Fire and Volume Control Dampers
  • External and Architectural Louvres
  • Natural Ventilation Systems
  • Domestic Warm Air Grilles
  • Tooling And Engineering

Over the years we have built a reputation for providing an extensive range of attractively styled, contemporary, value engineered products at the best in competitive prices. With comprehensive internal and external technical sales support we are able to provide very high standards of customer service and can respond quickly and efficiently to the many and varied demands of the building services industry.

Quality Assurance

Gilberts (Blackpool) Ltd designs, develops, manufactures, inspects and tests its products to ensure that they are suitable for the purpose for which they are specified, either as described in standard company literature or as agreed in a contract to meet our customer requirements. In order to ensure that this policy is effective, a relationship focused Quality Management System is implemented which complies with BS EN ISO 9001:2015. The Quality Management System ensures that the organization has the ability to consistently provide products and services that meet customer requirements and strives to exceed customer expectations as well as conforming to all applicable statutory and regulatory requirements.

Quality Assurance

Environmental Policy

As one of the UKs leading designers and manufacturers of Grilles, Diffusers, Louvres and smoke/Fire Dampers for the heating, ventilating and air conditioning industry, we have made ourselves aware of the consequential impacts that our operations may have on the environment. This we have done not only in relation to the resources consumed within the product manufacturing processes and also the energy utilisation characteristics of our equipment once installed.

Our commitment to care for the environment is translated into company policy and will be achieved by:

  • Continual and effective improvement of environmental performance
  • Compliance, as a minimum, with all applicable legislation, Gilberts requirements and any other adopted requirements which relate to our environmental aspects
  • Implementation and continued improvement of an occupational risk management system that meets the requirements of the International Standards Organisation, ISO 14001:2004
  • The setting and review of environmental objectives and targets
  • Review of the management system and policy to ensure their suitability, adequacy and effectiveness
  • Provision of suitable and sufficient environmental information, instruction and training to enable all staff to carry out their jobs competently
  • Selection and monitoring of competent third parties to ensure appropriate standards of environmental management are achieved
  • Effective communication and cooperation with third parties so that they are aware of our environmental management expectations
  • Environmental management is everyone’s responsibility, and a prime responsibility of all levels of management.
Environmental Policy

We will provide adequate and appropriate resources to implement this policy and will ensure it is properly communicated and understood.

Our aim, and those of the other Directors, is to encourage initiative and adopt best practice in a culture where employees and managers are aware of their individual responsibilities for the environment and actively engaged and committed to improving standards of environmental management.

Air Movement Facility

Air Movement Facility & Airflow Modelling

In 2015 our Air Movement Facility was fully redesigned and rebuilt to provide an all new, cutting edge Research and Development and Air Movement Test Resource

Air Movement

The Test Centre enables us to perform full air movement, product performance and research tests for new and existing products as well as undertake special tests or simulations to specific customer requirements.

Designed to ISO 5219 specifications we have superb versatility in room arrangement which, combined with the air handling unit and ductwork set-up, allows a controlled air flow to be supplied through numerous sizes and types of device in a multitude of floor, wall and ceiling mounting positions.

Experiments determine all key data including flow rates, pressures, velocities and temperatures and the computer control centre can then record all tests both visually and in data form. Supporting this we also have the latest Flomerics computational fluid dynamics airflow modelling software which, using a 3D CAD base, allows our engineers to generate a computer graphical model of any area complete with air terminal or other devices.

The models are then populated with sub- structures, fixtures and other heating/cooling loads which enables the software to accurately predict the air flow and heat transfer behaviour in 3 dimensions.

Air Movement

Using this software complex applications can be proven without the need for laboratory testing.

Airflow Modelling Software
"The Next Step in Air Distribution Technology"

Computational Fluid Dynamics

Gilberts, in collaboration with software manufacturer Flomerics, have been developing their CFD expertise and technology to bring about a bold new dimension to air terminal device selection. Based on the Computational Fluid Dynamics techniques the software, using a 3D CAD base, allows the engineer to generate a computer graphical model of any building or area complete with air terminal, or other, devices. The model can then be populated with sub structures, fixtures, fittings and any other heating/cooling loads enabling the software to accurately map and predict both the airflow and heat transfer behaviour in three dimensions.

With the models built, the software can be run and the air movement scenario examined. Although the calculations are obviously important a further key bonus is that these wire frame constructions and the solved data can then used by the software to generate animated models which provide a realistic environment for us to view the results in. As well as being a good visualisation tool these models also provide engineers with added value features such as.

1. Temperature/Velocity contour plots which can be moved through each axis within a model to show temperatures and velocities. Pinpoint readings can also be taken anywhere on these plots.

2. Vector Plots. These can also be moved through each axis highlighting any troublesome areas. In the case shown in fig 1 (a supermarket cold aisle) the vectors have highlighted air wiping over the lip of the cabinet, causing possible duty problems for the unit.

3. Surface plots to terminal velocities. This function allows penetration into occupied, or other, zones to be highlighted at any desired velocity.

4. Particle distribution video clips can be created in popular PC movie formats, which give us a clear visual indication of the air distribution patterns within the model.

Using this software complex applications and ideas can be proven without the need for laboratory testing. Even where testing may be necessary such as for a modified or non standard diffuser, the air movement lab can be used to confirm the accuracy of the simulation and the software used for future applications, saving both time and cost.

Computational Fluid Dynamics


These are times of increasing complexity with buildings being ever more bespoke. The Costs for services are at a minimum and the space in which to fit them is at a premium. Futureproof systems are also often required that allow flexibility in subsequent building use not to mention an increasing emphasis on environmental concerns and energy efficient design.

The need for the future engineer to be able to design an efficient, reliable and proven system both quickly and easily is clear. The future for CFD therefore looks bright!
