Mechon Ltd


MECHON offer a unique single source of expertise in the field of environmental air control systems. Our primary focus is on sustainable consulting, with designs that minimise the effects to the environment, increase productivity, and in turn reduce long term operational costs.

MECHON is able to undertake all aspects the project, from the initial concept design and consulting, to project management, and through to the final stages of installation and commissioning.

We at MECHON are not limited to selling specific products, enabling us to offer solution for your process or application. Please click on the links below for further details.

Dust and Fume Control

Thousands of British workers contract occupational asthma and other occupational lung diseases each year. They develop them because they breathe in too much dust, fume or other airborne contaminants at work. Even though the number of accident related deaths are reducing over the long term, deaths due to exposure remain stubbornly high.

Local exhaust ventilation (LEV) is a common and important way of controlling exposure to hazardous dusts and fumes. Work by the Health & Safety Executive (HSE) has shown that these LEV systems are often poorly designed and maintained and do not effectively control exposure to particulates.

Most LEV systems (but not all) will have the following components:

  • Inlet hood 
  • Ducting (trunking) 
  • Air mover (extraction fan) 
  • Air cleaner filter/abatement plant) 
  • Air discharge (stack)

Pneumatic Waste Extraction Systems

Advances in high speed finishing and converting equipment has lead to the need for continuous extraction of waste materials to improve production efficiencies, increase floor space, increase profit on recycled materials, and reduce materials handling activities.

Waste extraction technology is crucial for the efficient management of waste materials in the print, paper, corrugated, carton, board, and can industries. Waste extraction systems are designed to entrain waste materials at source, chopping if necessary, and conveying to a centralised collection point, using air as the conveying medium. The main components of a waste extraction system include:

  • Purpose designed extraction hoods, feeders, or belt conveyors
  • System of high-level, heavy gauge ductwork for material conveying
  • Chopper fans for airflow generation and breaking down of waste materials
  • Air separator to separate waste materials from the conveying air stream
  • Compactor or baler unit for waste collection and compression
  • Rotary airlocks to prevent pressurisation of collection unit
  • Filtration plant for the filtering of dusts from the conveying air stream
  • Air recirculation system for recovery of heat back into the facility
  • Briquetter for compaction of filtered dusts

Heating, Ventilation & Air Conditioning

Ventilation and air conditioning systems play a key role in the effective operation of any plant.

Ventilation and air conditioning systems will not only improve air quality, but also ensure that any remaining air systems (such as dust, fume and pneumatic conveying) operate efficiently and at their correct design duties.

Improving the state and quality of the air within a facility will result in potential savings due to reduced employee absenteeism, improved production efficiencies, and improved product quality, resulting from the comfortable environment.

HVAC techniques widely used by MECHON include:

  • Centralised air conditioning and evaporative cooling systems to improve air quality for employees and processes (including spot cooling)
  • Heating systems utilising gas and oil burners, or electric heater batteries
  • Make-up air systems to provide filtered or purified air to areas and ensure efficient operation of exhaust systems
  • Heat extraction systems from processes and equipment, including compressors
  • Destratification systems to improve heating efficiencies by recycling high-level warm air within facilities
  • Air Curtains to separate climate zones and prevent migration of fumes and odours
  • Air knifes for product cooling, cleaning, and drying
  • Clean rooms and differential pressure zones
  • Humidification systems to improve air quality and reduce static charge

Centralised Vacuum Cleaning

The Control of Substances Hazardous to Health Legislation states that the sweeping of dusts from surfaces must be avoided at all times. The use of vacuum cleaning technology prevents surface dusts from becoming airborne and subsequently inhaled via a trouble-free process. This means that as well as bringing health benefits to your employees and improving cleaning times, vacuum cleaning systems are now a legal requirement.

From chemical plants, laboratories, clean rooms, food facilities, aggregate plants, packaging plants, and general factories, MECHON are able to provide centralised vacuum cleaning (CVC) systems that are designed to meet the specific requirements of individual clients.

Heat Recovery

The Climate Change Levy of 1st April 2001 applies to energy used in the non-domestic sector with the aim of encouraging this sector to improve energy efficiency and reduce emissions of greenhouse gases . The introduction of the Climate Change Levy has resulted in companies paying specific attention to methods of energy saving and heat recovery.

Industrial processes use large quantities of fuel and electricity that ultimately produce heat , much of which results in energy waste or heat loss . The amount of energy required to reheat the displaced air can be considerable, and with higher gas and electricity bills, heat recovery is now a viable option.

Systems with the potential for recovery of waste heat include:

  • Fume and dust extraction systems
  • Ventilation and air conditioning systems
  • Air compressors
  • Incinerator and boiler flue gases
  • Curing, drying, and baking ovens
  • Furnaces
  • Turbines

Noise Control

Noise is one of the most widespread and underestimated of industrial hazards: exposure to excessive noise can cause deafness or ringing in the ear (Tinnitus). The Control of Noise at Work Regulations came into force on 6th April 2006, applicable to the majority of industry sectors within the UK. This new noise control legislation strengthens the protection of employees against the hazardous effects of noise.

The MECHON team are able to undertake a two phase action plan to resolve your industrial noise issues. The first step is to conduct an in depth noise assessment to determine the exact causes of high noise exposure levels. Equipped with this information, MECHON experts are able to select from a wide variety of sound reduction techniques to ensure improved working conditions of employees.

Noise control assessments are undertaken by competent persons and produced to the highest standard. Our noise assessments include the following content:

  • Identification of noise hazards
  • Identification of employees at risk from high noise levels
  • Noise exposure readings using a combination of sound level meters and dosimeters
  • Evaluation of noise levels to stipulated action levels within the Regulations
  • Evaluation of current noise control measures and recommended improvements
  • Advice on hearing protection zones, suitable hearing protectors and their use
