Packaged Plant Rooms: A Comprehensive Overview

What Are Packaged Plant Rooms?

Packaged plant rooms are self-contained units that house essential mechanical and electrical equipment required for a building’s operations. These pre-fabricated structures are designed, manufactured, and assembled off-site, then transported to the site as a complete package, ready for fast connection and use.

Size and Scale

The size and scale of packaged plant rooms can vary significantly based on the specific needs of the project. They can be as small as a container-sized unit or as large as necessary to accommodate all the required equipment for a major commercial or industrial building. The flexibility in design allows them to be customised to fit the exact footprint and height requirements of the installation site.

There are a number of standard sizes for these, based on the standard size for shipping containers. These are generally 10ft (3.05m), 20ft (6.1m) and 40ft (12.2m) and 8ft (2.44m) in width as standard. This standard sizing does make transportation easier, but can pose some issues around the actual space available for the plant to be fitted inside them.

At the other end of the scale, the acoustic packaged plant unit we built for Aberdeen heat and Power, to be installed at Kincorth was 4.2m wide x 10m long and was 4m high. This was the maximum size we could transport on UK roads from our factory in the North West to the site in Kincorth, a suburb south of Aberdeen. This was designed to serve well over 100 homes, up to three apartment developments, two schools and a number of other properties.

What Goes Inside a Packaged Plant Room?

Packaged plant rooms can house a wide range of equipment, including:

  • Heating and cooling systems: Boilers, chillers, heat exchangers, and air handling units.
  • Electrical systems: Transformers, switchgear, and control panels.
  • Pumping and water treatment systems: Pumps, filtration units, and water treatment equipment.
  • Ventilation systems: Fans, ductwork, and air filtration units.
  • Renewable energy systems: Solar inverters, battery storage, and other sustainable energy solutions.
  • Heat Pumps: The heat pumps themselves would need to be on the roof of the unit, but al of the wiring and inverters could easily sit inside the unit and still offer the required flexibility.
  • Packaged Pump Rooms: As you will see from the example below, we have designed packaged plant rooms to be submserible and yet still contain a pump system for an open water sourced heat pump system. It’s not a common request, but does show how flexible our deisgn and build team are with their solutions based approach to work.

Installing all of the components  in a controlled factory environment, ensures the quality of the work and reduces the likelihood of on-site issues. It also means we have any specialist skills that maybe required on hand which saves both time and cost.

Why Choose Packaged Plant Rooms?

Packaged plant rooms offer several advantages that make them a popular choice in modern construction and refurbishment projects:

  • Asbestos risk mitigation: In many older buildings, the presence of asbestos can complicate on-site construction or refurbishment projects. By using a packaged plant room, much of the mechanical and electrical work is done off-site, reducing the need for intrusive work and the associated risks of asbestos exposure.

We are seeing more and more examples where a decision is made to ‘abandon’ an older plant room and seal it up if there is a risk of asbestos. Pipes leading in and out are diverted to the new ‘pop-up’ plant room and the asbestos risk is mitigated.

  • Fast installation: Since the plant room is pre-fabricated, on-site installation is significantly quicker compared to traditional construction methods. This speed can be crucial in projects with tight deadlines or where minimising disruption to existing operations is a priority.

Many projects have a target of minimal disruption. For schools this means completed installation over one of the shorter holidays (Half term, Easter etc) and for healthcare or residential environments safety or comfort of guests. The ‘plug and play’ nature of a packaged plant room does effectively answer this problem.

  • Security: Packaged plant rooms are designed to be secure, with options for reinforced structures and security features like access control systems. This ensures that the critical equipment housed inside is protected from theft, vandalism, or unauthorised access.
  • Optional finishes: These units can be customised with various finishes to match the aesthetic or functional requirements of the site. Options might include weather-resistant cladding, soundproofing, or even architectural finishes that help the plant room blend into its surroundings. You will see from the selection of images below a range of the finishes we have already completed.
  • Built to be enclosed: We have completed a few projects recently where the brief has been to create a simple finish package to allow it to be contained behind either and existing or newly created wall. The Wirral Grammar job below is a good example, where the finished plant room was enclosed in a brick facing and completed, almost looks like it’s hidden inside a roofless building. Others are designed to fit inside an existing space and simply lifted into place and connected when in situ.
  • Designed to your current and future specification: Packaged plant rooms offer significant flexibility in both size and specification. They can be designed to meet the exact requirements of a project, whether that means fitting into a confined space, accommodating specific equipment, or being easily expandable for future needs.

The simplicity of the design also gives you a blank canvas for future developments. If the demand changes the unit itself can quickly be updated or the plant inside can be changed as required.

Different Types of Packaged Plant Rooms

  1. Fixed Packaged Plant Rooms: These are permanent installations, typically used in larger projects where the plant room will remain in place for the life of the building. They are built to last and can be fully integrated into the building’s infrastructure. A good example of this is the one we completed for Wirral Grammar.
  2. Portable Packaged Plant Rooms: Portable units are designed for easy transport and relocation. They are ideal for temporary installations, such as during construction phases, or for projects where equipment may need to be moved between sites. Depending on the length of the requirement, these can easily be hired in and temporarily connected to cover the required time. A good example of this is the one we used for Claire House.
  3. Acoustic Packaged Plant Rooms: In environments where noise control is critical, acoustic packaged plant rooms are used. These units are equipped with soundproofing materials and design features that minimise noise emissions, making them suitable for use in residential areas, hospitals, or other noise-sensitive environments.

A good example of this is the one we created for Kincorth. This was a unit filled with large scale plant that was located very close to residential homes. By siting it all inside an acoustic plant room, even those who lived very close to the unit would not hear the noise from it, even in the quietest times.

Conclusion

Packaged plant rooms are a versatile, efficient, and secure solution for housing essential mechanical and electrical equipment. Their ability to be custom-built, combined with the speed of installation and flexibility in design, makes them an attractive option for a wide range of applications.

Almost any plant room installed in the 1970’s or early 1980’s will probably be at severe risk of containing Asbestos. To mitigate this a packaged plant room can circumvent all of the areas that could contain asbestos and allow you to connect into the existing heating system within a building.

Installing a packaged plant room is almost certainly a faster, safer and cheaper option than rebuilding a new one from scratch, if Asbestos is present.

Whether fixed, portable, or acoustically optimised, packaged plant rooms offer a modern approach to managing the complex infrastructure needs of today’s buildings.

At Kimpton, our expertise in plant for HVAC is unparalleled. We understand what works and how it works at its best. The design and build of packaged plant rooms is an area we know well.

Fixed Packaged Plant Room Case Studies

Wirral Grammar

The existing basement plant room was shared with the Wirral Grammar for Girls next door and each had three cast iron oil fired boilers that were approaching the end of their working life. During an early assessment, the plant room itself was found to contain asbestos, so the decision was made to create an externally sited packaged plant room as a direct replacement.

Cardinal Newman

Having created and lined a new container that was purpose made for the size available, it was ready to go for the team to install the plant on our own site to install at the School, when the Easter break started.

The plant room was fitted with four Ideal Evomax 2 150kw boilers. On efficiency alone they have the old oil fired system beaten, with around 97% efficiency compared to nearer 60% from the old system. Combined with the ability to cascade boilers (ie only fire up as much power as is needed to meet the demand) the ongoing savings in fuel and carbon footprint are huge.

Acoustic Packaged Plant Room Case Studies

Aberdeen

Kimpton were employed by Aberdeen Heat & Power to design and manufacture two bespoke containers to house CHPs’ for two separate district heating schemes in Scotland.

Manufactured at works the containers were constructed from a base frame with acoustic panels secured with H joiners between. The roof comprised an inverted pitch with internal rain pipes to comply with planning. For aesthetics the enclosures were timber clad.

Kincorth

This is another acoustic plant room project for Aberdeen Heat and Power and has just been delivered to site, ready to put into action, serving the Kincorth District Heating Scheme. It follows on from another we delivered for the Stoneywood district heating system.

A district heating system uses a central plant to provide heat to a group of buildings. At the centre of this is a power generator and boilers that produce hot water, which is circulated to individual homes or buildings. By housing these within an acoustic plant room, it delivers the power where it’s needed, without noise pollution for the local residents.

Packaged Plant Pump Rooms for Heat Pumps

One plant room that was very high profile was the one designed and built for the Plas Newydd, open water sourced heat pumps system. This contained all of the pump equipment for the system and drew the water in from the open sea. It’s proximity to the sea meant it had to be designed to be battered by the elements and at times, submerged.

Within the freestanding plant room there is all of the kit required as well as lighting. It is all built from marine grade materials.
