At Dunphy, we specialise in off-site manufactured packaged plantroom solutions that provide flexibility for customers with unique energy needs. Packaged plant rooms are self-contained energy centres designed and manufactured off-site in our factory complex in Rochdale. Each package plant room is custom-designed to match the bespoke characteristics of your site, including space availability, fuel types (fossil or biofuel), and the required generation process – for steam, hot water, heat treatment, or combined heat and power (CHP).
The plant room is designed, constructed and tested at our premises and then transported to the site where it is reassembled, commissioned and ready to use.
At Dunphy, we deliver fully prefabricated packaged plantrooms that are tailored to your specific needs and built to the highest standards. From initial design to final commissioning, our expert team supports you through every stage – including construction, installation, testing, and inspection. This ensures your project is completed efficiently and on schedule.
All core components are manufactured in-house, including:
We also produce all necessary technical documentation, such as FDS reports, DSEAR analyses, and SIL assessments.
Once on site, the plantroom is quickly reconnected and commissioned by our experienced mechanical and electrical engineers, minimising downtime and disruption, essentially they’re plug in and play. These self-contained systems are ideal for restricted spaces and are future-ready, supporting low-carbon technologies and renewable integrations – making them a smart, scalable solution for both new installations and system upgrades.
Packaged plantrooms are used across a diverse range of industries that require dependable, high-efficiency energy systems. Typical sectors and businesses that benefit from packaged plantroom solutions include:
Hospitals and healthcare facilities – for consistent heating, hot water, and sterilisation systems
Schools, colleges, and universities – offering scalable, centralised energy solutions for multiple buildings
Manufacturing and industrial plants – ensuring reliable process heating and energy management
Food processing facilities – where hygiene and temperature control are critical
Pharmaceutical and chemical sites – requiring strict compliance and safe energy infrastructure
Data centres – supporting cooling systems and backup power integration
Commercial developments and office buildings – reducing installation time and on-site disruption
Leisure centres and hotels – maintaining hot water and heating for large-scale use
Large residential developments – providing a compact energy solution with minimal visual impact
