Good indoor air quality will enhance the health and comfort condition of the people who live or work within a given building. Failure to respond to indoor air quality issues may result in the following:

  • Recurring health problems.
  • Increased absenteeism resulting in reduced workplace productivity.
  • Damage to surrounding furnishings and the premature failing of electrical items.
  • Increased tension between staff, management and/or maintenance personnel.

Clearwater offer a comprehensive range of cleaning and air quality monitoring services to ensure that systems are well maintained, operating efficiently and compliant with the required air quality standards:

Kitchen Extract Cleaning

To prevent fire and/or possible bacterial contamination of food; health and fire regulations, and insurance companies, call for high standards of maintenance and cleanliness within kitchen extract systems.

Clearwater specialists carry out full system length degreasing and cleansing in order to meet fire safety requirements. On completion we provide description of works, cleaning methods used; COSHH data; photographic evidence; certification and recommendations for future cleaning requirements.

Ventilation Hygiene

Mechanical ventilation systems (including air conditioning systems) should be regularly and properly cleaned, tested and maintained to ensure they are kept free from contamination.

Clearwater specialists offer a comprehensive range of ventilation system services. These include; initial surveys, reporting, planned maintenance program development, full system cleaning and refurbishment. This can also include bacteriological sampling and analysis.

L.E.V Testing

Local Exhaust Ventilation systems must be maintained in a good working condition in order to effectively remove pollutants from the workplace and dispose of them in a safe manner. Current legislation requires that Local Exhaust Ventilation systems are well maintained, thoroughly examined and tested at least every 14 months.

Clearwater qualified engineers use a variety of test methods including vane and hot wire anemometers with the findings presented in Clearwater’s own COSHH compliant test certificate accompanied by a summary detailing and prioritising any remedial works or performance improvements that are required for each system.

Indoor Air Quality Monitoring

Clearwater’s ’spot check’ assessment, longer term or indoor air quality monitoring programmes can be used to confirm that the ventilation plant is being maintained at an acceptable hygienic and mechanical standard as well as ensuring that the building complies with current legislation.

A typical Indoor Air Quality Assessment will consist of measurements of thermal comfort, which incorporates air temperature, relative humidity, and air velocities within the occupied areas. Carbon dioxide levels and other Noxious gases such as carbon monoxide, ozone and formaldehyde within the working environment, which would give an indication as to whether the fresh air rate supplied is in sufficient quantity to remove unpleasant odours and other internally generated pollutants.

Measurement of airborne particulate, bacteria and fungal contamination levels within the office areas compared to recognised guidelines.

Clearcoil Coil Cleaning

We use our ClearCoil cleaning process to ensure coils are chemically deep cleaned after manual vacuuming and jetting with compressed air. Our ‘toolbox’ approach to cleaning enables us to remove contaminants using the appropriate tools and methods to ensure your heat exchange coils and other components are left in a clean, functional and efficient state to significantly improve performance and reduce energy bills.

Our service is backed up with a full pre and post clean verification report demonstrating the increased efficiency of your plant. The verification report contains a data table outlining all of the measurements taken both pre-clean and post clean, and including a calculated estimate of the Energy Savings for a year, based on the size of the system, the fan efficiency, the cost of electricity and the number of hours the system is online each year.
