HVAC Products and Systems We Supply in Johnstone
By mastering the entire commercial HVAC specification, CEG supports Johnstone contracting teams and advisers. Every new build, refurbishment, and fit-out is seamlessly covered.
Whether obtaining air conditioning systems for commercial developments or upgrading ventilation throughout operational premises, our close manufacturing partnerships and deep engineering expertise thoroughly support your specific specifications.
Air Handling Units (AHUs)
AHUs manage and distribute fresh air throughout properties by making use of integrated ventilation ductwork.
Located at the centre of many commercial ventilation designs, they regularly deliver required ventilation, humidity management, and indoor air quality control throughout the premises.
Our enterprise supplies AHUs in conventional, sanitary, sectional, compact, and custom configurations, meeting the needs for both new-build and remodelling developments in Johnstone and the broader UK.
Take a guess what? Each unit features Eurovent certification and ErP 2016 compliance, with technical documentation fully included!
Distinctive specifications? Our excellent manufacturing partners will engineer everything to your exact project brief!
Fan Coil Units (FCUs)
Johnstone offices, hotels, and mixed use buildings rely on fan coil units as their standard heating and cooling solution.
To meet the majority of installations, simply use ceiling-concealed, exposed, floor-standing, or high-static ducted configurations.
Putting first energy performance requirements? We provide highly effective EC motor options for your requirements!
We provide the units with controls, valve and actuator packages, and condensate pumps.
We work closely with our manufacturing partners to create bespoke heating and cooling systems, meticulously tailoring each unit to your precise size specifications and thermal capacity requirements.
Grilles, Louvres and Diffusers
Decades of knowledge shape CEG’s heritage in grilles, louvres, and diffusers. Certainly, our heritage is firmly linked with renowned, market leading manufacturers across the UK, Europe, and the wider globe.
The collection gracefully suits straightforward commercial fit outs and high-end architectural interiors in equal measure.
Within elegant architectural developments, bespoke sizing and precise finishes carry comparable critical importance as overall airflow capability.
Capturing true artisanship, powder coating, RAL colour matching, and anodised finishes elegantly lift our entire grille and louvre ranges.
Our manufacturing partners engineer tailored configurations when standard products do not manage to meet your technical brief.
Looking for the entire package? Alongside the main units, we provide plenum boxes, volume control dampers, fixings, and bird and insect mesh, providing M&E contractors and building services consultants one superb partner for air distribution procurement!
Natural Ventilation Solutions
By making use of NVU, e-Stack, and hybrid configurations, natural ventilation systems passively circulate fresh air with negligible mechanical aid, carefully meeting the specific requirements of schools, workplaces, and business buildings.
Whenever architectural plans facilitate energy-efficient solutions instead of complete mechanical ventilation, these configurations can deliver considerable utility savings across the lifespan of the property.
Do you need the ultimate setup? CEG suggests the ideal natural ventilation configuration at the planning stage!
Trench Heating and Radiators
Banish the cold snap! Trench heating releases gentle heat at the floor level under glazed facades, addressing the worst cold downdraughts.
Ready for more flexible layouts? Natural-convection and fan-aided LPHW units are installed flush with the floor finish, delivering a perimeter thermal barrier without limiting wall or furniture layouts!
In harmony with our trench heaters, we deliver bespoke and regular steel panel radiators in a range of elegant finishes.
We carefully set these low-temperature selections to align with the operating flow temperatures of heat pump and ground source systems.
Should standard proportions prove unfit for your project, the production partners can provide tailored solutions, including curved and slanted units.
Air Curtains
By separating indoor air from the outside environment, air curtains reliably help preserve temperature regulation at building entrances and loading bays.
Consider recessed, exposed, or industrial set-ups, each smartly finished with matching controls and accessories.
Working out the correct specification requires precise doorway measurements, the total aperture scale, and the thermal variance the unit must handle.
We provide exact sizing and selection advice for commercial shop and industrial projects throughout Johnstone.
Ventilation Products and Accessories
The main HVAC units constitute merely one section of the wider specification.
The dampers, attenuators, mixing boxes, and ductwork accessories gracefully round off the mechanical ventilation design. They expertly span the gap between extract air, airflow management, and in duct components.
Using a single supplier gives you a dedicated contact, which removes one complication while your programme is in progress.

FAQs on Air Conditioning & Ventilation Requirements
What does HVAC stand for?
Encompassing heating, ventilation, and air conditioning, HVAC technology regulates indoor environments through winter warming, warm-weather cooling, and constant air quality preservation. Specifying the optimal system demands a careful assessment of the building architecture, full scale, and specified energy efficiency targets.
Does CEG carry out HVAC installation in Johnstone?
Certainly, CEG acts as a specialist distribution partner rather than an installation team. We supply the vital HVAC products and systems to M&E contractors and building services consultants, who then undertake the actual air conditioning installation, commissioning, and ongoing maintenance on site.
Which types of HVAC products does CEG supply?
From AHUs and FCUs to vent grilles, louvres and diffusers, natural ventilation systems, trench heating, radiators, air curtains, and ventilation accessories including dampers, attenuators, and mixing boxes, our reach is vast. We stand as the dedicated single point of contact for HVAC services in Johnstone and across the UK, seamlessly meeting the entire commercial specification.
