Recognising that dedicated plant room space in buildings is becoming a challenge for equipment providers, Ellison AC has developed packaged plant room solutions that are factory made and delivered for installation on roofs, on concrete pads or even underground.
Packaged plant rooms are popular across a wide range of customers, from defence to data centres, to business and shopping centres. The plant rooms are made in modules to allow them to be easily delivered and installed on-site. Once the plant room is complete and tested in the factory, each module is packaged for delivery to site, with minimal commissioning required.
Developed, designed and built offsite
As Projects Director Neil Dodgson explains: “We can develop, design and build a product purely offsite. Generally, we’re off the critical path of the main build of a contract, so ultimately you can have the building being built 20 stories and literally as soon as the site is ready, we can deliver our equipment and install it within the space from an hour or up to a weekend.”
That client relationship also means that Ellison looks to pass the benefits of the products they use inside their packaged plant solutions along to their customers. This includes even the variable speed drives they use to control the pumps. “We have long recognized the advantage of controlling our pumps with VSD’s to provide the energy efficiency essential to meet the latest building regulations.” Neil Dodgson explains.
In HVAC applications, using a variable speed drives on pumps and fans help reduce energy consumption significantly (compared to throttle/damper control with direct-on-line motors). With pumps and fans, a 20 percent reduction in motor speed can reduce the power required by up to 50 percent.
ACH550 used for energy saving
Ellison AC decided to use ABB’s drive for HVAC, the ACH550, to control the pumps used in the heating, chilled water and condensed water applications in the packaged plant rooms. The design of the ACH550 even helps reduce build time and costs since it doesn’t require additional back-plate mounting.
But the real plus side to using ABB’s drives is the benefit they deliver to their end-customers, as Neil Dodgson explains “We’ve got to look for a product that is of excellent quality, and offers ease of installation both for the mechanical and electrical side of things. But ultimately we’ve got to look for a product that also brings benefits to our end-users – the people who are actually working day-today on the contracts. The ABB product benefits us initially, but will ultimately give the client the end-benefit.”
