Pressurisation to productivity: clearing the smoke in F1 wind tunnels

Posted by Laurence Cockman on 11/09/20 13:30

Planes, trains, speedboats, racing bikes and Formula 1 cars might not have been what they are today if it wasn’t for a key technological advancement - wind tunnels.

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.

The complementary duo: Enhancing AHU’s with a natural ventilation solution

Posted by Andrew Wright on 14/07/20 10:00

Sometimes, even a good HVAC system can be improved.

The effectiveness of a centralised air conditioning system is dependant on a number of factors and can change over time. Upon assessment, it may be the case that a system no longer operates optimally in its environment, and could be combined with another system to enhance its efficiency.

In this post, we illustrate this point, and explain how sometimes enhancing existing systems can be a great solution for industrial buildings.

Colt’s Ventilation Solutions Resolves Factory’s Excess Heat build-up

Posted by Andrew Wright on 18/06/20 14:00

The key to delivering great ventilation services is to not only focus on the functionality and efficiency of the system but to also consider the challenges unique to each company.

Through working with Cross Manufacturing, we illustrated how we can tailor solutions to resolve ventilation issues whilst taking the wider community into consideration.

In this post, we share how we delivered a ventilation service to Cross Manufacturing’s factory that efficiently resolved their excess heat build-up problem, whilst honouring their duty of care to the local residents.

Parasitic loads: powering ahead with natural ventilation

Posted by Paul Langford on 27/05/20 10:00

Techniques of natural ventilation that work well in conventional power plants are becoming even more important with the growth in waste-to-energy plants. All power station operators are keen to minimise the ‘parasitic loads’ - the proportion of the energy that they generate that is used to keep the plant running and the relatively small numbers of staff that work there comfortable.

Digital printing: printing to perfection

Posted by Paul Langford on 13/05/20 10:00

Ensuring stable indoor conditions for digital printing is essential and can be costly. Achieving a constant temperature is fairly straightforward but a consistent humidity level is more challenging. First developed in the early 1990s, digital printing is a rapidly growing and sophisticated technology. Fast and reliable, it is however very dependent on having the correct print room conditions. The moisture content of the paper can affect the toner adhesion, paper jams and the fuser roller temperature.

Why air quality really matters

Posted by Paul Langford on 30/04/20 11:00

We have known for some time that indoor air quality at home can be a problem, but a new report produced jointly by the Royal College of Paediatrics and Child Health (RCPCH) and the Royal College of Physicians (RCP) highlights just how serious an issue this can be. In particular, it says, poor indoor air quality can impact child health.

It links indoor air pollution to a range of childhood health problems including asthma, wheezing, conjunctivitis, dermatitis and eczema. There are a number of potential causes of indoor air pollution. They can include smoking, damp, the burning of fossil fuels and wood, dust, chemicals from building materials and furnishings, aerosol sprays and cleaning products.

Colt Case Study - Camplings Linen

Posted by Paul Langford on 19/02/20 11:00

If you live in East Anglia and eat in a restaurant with linen tablecloths, or if you stay in a hotel in the area, you may well be using cloths, bed linen or towels that have been laundered by Camplings Linen. Formed by a merger of two companies, it now operates under the brand Camplings in Great Yarmouth and as Swiss Laundry in Cambridge. Both locations had the same potential problem – laundry is a hot and steamy business and, while this is good for the linen, it is less good for the people who work with it.

Granger Hertzog’s brief to Colt was to ensure the comfort of the staff all year round

Posted by Paul Langford on 06/12/19 11:00

If you saw the film Rocketman, about Elton John, or watched the television adaptation of His Dark Materials, you will have seen furniture and props from specialist hire company Granger Hertzog. The company operates from a combined office, warehouse and showroom in Park Royal, London, all accommodated within a light industrial shed that is one of a number on an estate.

How to deal with engine exhaust emissions when local exhaust ventilation is not an option

Posted by Paul Langford on 10/10/19 10:00


Controlling diesel engine exhaust emissions in enclosed spaces such as maintenance workshops is easily done with local exhaust ventilation (LEV), which can be as simple as fitting pipes to the vehicles’ exhausts while they are being serviced in order to draw the fumes outside. However, there are situations where this is not an option, for example in a warehouse where there is heavy vehicle movement inside the building, as vans and lorries come in and out for loading and unloading.

Is evaporative cooling safe?

Posted by Paul Langford on 19/07/19 15:00

The first question that comes up when discussing a water based cooling system, such as evaporative cooling, is always about its safety and in particular about the control of legionella bacteria. In this article we will explain what you should be looking at if you are considering such a system, illustrating with examples of our approach to ensure that our evaporative cooling systems are safe.
