Innovative AHU Control Systems
Purpose-built AHU control solutions designed to improve performance, reduce installation time, and give you complete visibility across every system, from simple units to complex modular applications.
Custom-built HVAC Control Systems
Custom HVAC applications engineered to simplify building automation, reduce energy waste, and deliver intuitive digital interfaces that give your team
total control over your environmental systems.
SOFTWARE DEVELOPMENT
Bespoke HVAC control software engineering.
Modern infrastructure, datacentres, and emerging climate technologies require specialized control logic that conventional HVAC systems cannot deliver. At iACS, we design custom control panels and develop bespoke, PLC-based software engineered for non-standard architectures, seamlessly bridging the gap between complex hardware and intelligent automation.
Whether you are an industry innovator launching a new technology, an OEM, or a contractor managing a large-scale project that requires disparate systems to communicate, our engineering team transforms complex concepts into fully operational, purpose-built control solutions.
From optimizing standard AHU, MVHR, and smoke extract systems to programming ultra-bespoke software for advanced residential and industrial applications, we deliver made-to-measure reliability. We provide the precise integration required to keep your unique systems efficient, scalable, and completely under control.
WHAT WE DO AT iACS
Turning complex ideas into intelligent control solutions.
Our software development team works closely with OEM manufacturers, consultants, contractors, facilities operators, and technology partners to design and deliver software that solves real operational challenges.
Rather than forcing projects into predefined products, we build solutions around the application, ensuring the software performs exactly as required while remaining scalable for future growth.
Whether the requirement involves HVAC controls, industrial automation, IoT connectivity, cloud infrastructure, mobile applications, or specialist equipment integration, our engineers provide the technical expertise needed to deliver successful outcomes.
