Clearwater’s dedicated AirCare division consists of specialists with expertise in assessing indoor air quality, ventilation hygiene and local extract ventilation (LEV) testing as well as remedial works such as ductwork cleaning, kitchen extract cleaning and HVAC heat exchanger coil deep cleaning.
Poorly maintained working environments will have far reaching consequences over the course of time, impacting the wellbeing of all working in those conditions. Mechanical ventilation systems typically form a significant proportion of a building’s fabric and interior surface area and the associated ductwork is typically hidden and not often subject to frequent inspection or maintenance. It’s not uncommon to find significant contamination from build-ups of dusts, moisture, insects, vermin, pest droppings and building materials left behind following construction.
Without sufficient control measures in place there are potential health risks to occupants and additional costs to building owners and managers. These risks include:
- Reduced air-flow/increased energy consumption
- Reduced plant life
- System components becoming clogged or corroded and rendered inoperable
- Dust particles on sensitive equipment
- Dirt staining on furnishings and décor
- High staff turnover and absenteeism
Clearwater’s AirCare division has the expertise to assess air handling systems and can recommend and perform remedial actions where required.
Higher indoor air quality will enhance the health and comfort of the those 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 failure of electrical items.
- Increased tension between staff, management and/or maintenance personnel.
Clearwater offers 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
- Ventilation Hygiene
- E.V Testing
- Indoor Air Quality Monitoring
- ClearCoil Coil Cleaning
Kitchen Extract Cleaning
To prevent fire and/or possible bacterial contamination of food, health and fire regulations and insurance companies require high standards of maintenance and cleanliness within kitchen extract systems.
Clearwater’s specialists can carry out full system length degreasing and cleansing in order to meet fire safety requirements. On completion, we provide in-depth descriptions of works carried out and cleaning methods used; COSHH data; photographic evidence; certification and recommendations for future cleaning requirements.
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 including initial surveys, reporting, planned maintenance program development, full system cleaning and refurbishment. This can also include bacteriological sampling and analysis.
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 indoor air quality monitoring programmes include ’spot checks’ and longer term assessments that can confirm whether the ventilation plant is being maintained to an acceptable hygienic and mechanical standard while 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. Measuring carbon dioxide levels and other noxious gases such as carbon monoxide, ozone and formaldehyde within the working environment indicates 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 can be compared to recognised guidelines to ensure that the building is compliant.
ClearCoil Coil Cleaning
Clearwater’s ClearCoil cleaning process ensures 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-clean and post-clean verification report demonstrating the increased efficiency of your plant. The verification report contains a data table outlining all measurements taken both pre-clean and post clean, and includes a calculated estimate of the annual energy savings 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.
In all cases, Clearwater differs from traditional approaches in using an open, flexible and nimble approach to create the right team to make a rapid difference to their clients’ businesses. Contact us today to find out more.
