Car Park ventilation: dealing with overheating in underground car parks.

Posted by Laurence Cockman on 21/09/21 10:00

It is commonly known that underground car parks need to be ventilated to remove the build-up of exhaust fumes and in some instances for smoke ventilation. However, another common problem that is less discussed is the need for ventilation in underground car parks and basements where overheating occurs due to air conditioning condenser units being installed within them. This is the problem that we helped our clients at “Discovery” solve.

To understand why this issue occurs, let’s start with a basic explanation of how a traditional AC system operates and how it should be installed to get the maximum performance out of it. Typically, traditional air conditioning systems have an internal and external unit that work together to exchange warmth and coolth to achieve the desired internal temperature. In the summertime, the air conditioning system provides cool air by actually removing heat from the indoor air, transferring it to outside through a pipe circuit filled with refrigerant.

Industrial fume extract solutions from Colt

Posted by Ginny Williamson on 31/08/21 10:00

Colt was recently commissioned to work on a project at a car parts manufacturing plant that required some creative thinking when it came to fume extract.

This particular facility had large galvanizing tanks used as part of the manufacturing process. The existing extract fans which were located directly above the tanks had been out of service for some time. Their location meant it was extremely difficult to access for maintenance, and repairs. Repairing the existing fans would require extensive scaffolding equipment to be set up and many days of production lost which was impractical and not cost effective.

Is evaporative cooling better than air conditioning for your business?

Posted by Paul Langford on 23/04/21 10:00

Evaporative cooling or ‘adiabatic cooling’ is a mouthful, we know. That’s why a lot of building owners and operators still don’t know about the effectiveness of these systems or the cost and environmental benefits they can deliver.

Many people don’t realise that if you manage a large industrial or semi-industrial facility where pinpoint control of temperature isn’t crucial, evaporative cooling can actually be a more effective choice than traditional air conditioning. Just have a look at the pros and cons associated with the different system types below – not only is evaporative cooling cheaper and more efficient, it introduces fresh air from outside avoiding poor health issues often associated with traditional systems.

Read on to find out what evaporative coolers are and why they could be better for your business than a traditional air conditioning system.

A CASE STUDY ON VENTILATION DESIGN IN WAREHOUSES

Posted by Ginny Williamson on 05/02/21 10:00

With more online ordering than ever and customers expecting goods to be delivered rather than picked up, warehouses and logistics centres have never been busier. From a health and safety perspective, this can cause problems when staff are sharing workplaces with vans, trucks and other fume-producing vehicles on a daily basis. Adequate ventilation in these centres is absolutely crucial.

The case study below demonstrates how Colt helped create a safe, healthy atmosphere for the staff at the DHL warehouse in Lincoln with a tailored fume detection and hybrid ventilation solution.

How your building can help in the fight against COVID-19

Posted by Paul Langford on 19/11/20 13:00

As we all get to grips with the latest lockdown, businesses have to explore new ways of working in a COVID-19 secure manner. So how can you ensure that your workplace, be it a factory, warehouse or office, is properly prepared to reduce the risk of the spread of Coronavirus amongst your workforce.

In our previous blog we explored some of the latest scientific theory surrounding the potential for the airborne spread of COVID-19 through building ventilation. For building managers it is very important to be fully aware of every step they can take to limit the transmission of contaminants in the workplace.

In this blog we aim to suggest some practical steps you can take to make your building COVID-19 resilient – it’s important to remember that where viruses are concerned the realistic goal is to make your building ‘safer’ rather than ‘safe’. It’s simply not possible to eradicate completely the potential of a COVID-19 outbreak in a typical workplace as there are other factors, beyond your control, which come into play.

How good ventilation can help to combat COVID-19 in buildings

Posted by Paul Langford on 09/10/20 10:00

As the scientific knowledge around the spread of the Coronavirus continues to develop, it is important to know which information is both correct and relevant for ventilation systems. The airborne potential of COVID-19 is high according to a recent report by the British Medical Journal which stated that microscopic respiratory droplets containing COVID-19 can hover in the air for minutes or even hours, and potentially drift many metres horizontally. Therefore, it is necessary for the air ventilation industry to be fully up to date with the latest theory around the capability for the airborne transmission of COVID-19.

NO₂ vs CO – what you need to know?

Posted by Laurence Cockman on 13/08/20 10:00

Not all vehicle emissions are made equal. First, the pollution created in buildings by cars, vans and lorries must be detected. Once detected, we must understand which pollutants will be present in the air as a result of how the building is used. A qualified engineer can then install the optimal system to avoid the health risks associated with Carbon Monoxide and Nitrogen Dioxide.
