HVAC Services for High-Security Environments.

Ensuring compliance, controlling climates, and maintaining wellbeing.

High security environments bring their own challenge when it comes to effective ventilation and climate control – large numbers of people in confined spaces requires careful design and well-planned maintenance to ensure the wellbeing of staff and other building occupants.  They also bring the challenge of additional security clearance for engineers and other conditions, all of which Salix has achieved.

We Have Experience


Salix has worked in a number of prisons including HMP Highdown, HMP Highpoint, HMP The Mount to name a few.  Most of this work has been in relation to the repair and refurbishment of Air Handling Units, ensuring adequate and sufficient fresh air ventilation to spaces.

What difference does Salix make?


Focus on Ventilation

While it may not have seemed an important topic before, Covid has highlighted the essential need for effective ventilation, especially in high-occupancy spaces like Prisons

Security Clearance

It is not any contractor that can work in high-security venues like prisons, but Salix has got the necessary clearance to enable us to meet these demands

Ensuring Compliance

High-security buildings, like any other public space, have an obligation to meet compliance requirements in terms of F-gas and Gas safe checks – we can help with all of this

Keeping to Budget

An effective HVAC maintenance programme ensures cost-control, both through system operating efficiencies and longevity of HVAC assets
