iACS Welcome to the UK's home of air handling and ventilation since 2011! iACS were born in 2011 as i-A.C.Systems.

London based control panel specialists and HVAC spares distributors. 4,000+ control panels and 19,000+ HVAC parts supplied worldwide. Operating from a shoe box office in South East London and employing 1½ people - the space was small but the vision was huge! Fast forward to 2019, iACS have made a name for themselves in the UK as Air Handling Control Experts - the software team work relentlessly i

n ensuring that the AHU control solution remains ahead of the curve while our in-house panel build team work to the highest standard in order to achieve quickest turnaround in the Industry. As the only Systems Integrator in the UK specialized in AHU controls and backed with over 25 years experience, it’s no surprise that our client retention rate exceeds 95% - no one does AHU controls quite like us..

Behind every calm engineer is a thousand problems nobody else even noticed 👏
Keep showing up, keep learning and trust the process even on the difficult days. The people who build great systems are built through pressure too.

Looks like I’ve got it together until the panel starts fighting back 😭 💀

“Character building” according to the senior engineer was carrying tools up 12 flights of stairs and getting shouted at for holding the torch wrong 😂

Every HVAC apprenticeship starts with trauma and ends with experience 👨‍🔧⚙️

When you spot the mistake at 4pm on a Friday and suddenly everyone starts acting like it was “already like that” ⚡😂

Funny how the panel looked perfect right up until commissioning 👀

Introducing iX-HTM! A new standard for healthcare ventilation control.
In healthcare environments, ventilation isn’t just about airflow, it’s about patient safety, clinical performance, and absolute reliability. And while most conversations focus on the AHU itself, the control strategy behind it is just as critical.
That’s why we’ve developed iX-HTM, a purpose-built extension of our iX platform, designed specifically for healthcare and HTM-led applications.
This isn’t a generic control panel adapted to fit. It’s a solution engineered from the ground up to meet the demands of hospitals, operating theatres, clean environments, and critical care spaces.
🔹Clear operational visibility: real-time status, alarms, airflow conditions, and environmental data communicated directly to surgeon’s panels
🔹 Integrated control philosophy: supporting multiple operating modes, occupancy states, and clinical requirements
🔹Direct user interaction: temperature and humidity monitoring and adjustment at the point of use
🔹Fail-safe continuity: structured local override strategy ensuring safe airflow even in PLC failure scenarios
🔹Smarter integration: designed for seamless coordination with BMS, specialist panels, and wider building systems
Healthcare spaces demand more than basic run/fault logic. They require clarity, resilience, and confidence in how systems behave, in normal operation and under fault conditions.
iX-HTM was created to solve exactly that.
It removes ambiguity.
It strengthens system resilience.
And it aligns control strategy with how healthcare environments actually operate day-to-day.
Because in critical environments, control isn’t an afterthought, it’s the foundation.

In critical healthcare environments, fail safe control is not optional ⚙️🏥

With iXHTM, a PLC failure does not mean losing control of the AHU. Our hardwired override sequence is designed to maintain safe and functional airflow, even during failure scenarios.

✔️ Automatic damper opening
✔️ Fan enable confirmation via end switches
✔️ Manual speed control through local potentiometers
✔️ Safe airflow maintained during PLC failure

Because resilience and HTM compliancy matter when patient safety is on the line.

Flexibility that saves time, cost, and headaches. ⚙️

Our iX Controls platform is designed to adapt to real-world projects, giving engineers multiple ways to connect and integrate sensors without needing major panel modifications.

✔️ Direct controller inputs
✔️ MP-Bus integration
✔️ Actuator-connected sensing
✔️ BMS-fed sensor values via comms

More flexibility means easier upgrades, simpler commissioning, and fewer costly changes onsite.
