Partnership delivers System

Execllence

With over 35 years of technical expertise

Crossflow Air Conditioning installs, commissions,

services and maintains all types of air

conditioning equipment, from standard

split air conditioning for single offices

rooms to large vrf multi room/office applications. 

In addition to providing system solutions, Crossflow

also offers project management, technical

investigations and reports, and full facilities support – 24

hours a day, 365 days of the year.

As such, it is the perfect trading partner for Hitachi.

Together, they have been responsible for some of the

most prestigious air conditioning and refrigeration

projects in Ireland in recent years. These include major

installations at Deloitte’s Earlsfort Terrace

headquarters in Dublin and at Euro Medic in Santry, Co

Dublin. Project manager for Deloitte was Gary Bartley

and the equipment was a Sumurai RCUE 120AG2

chiller, while Kieran Timmons of McKenna

Engineering was project manager on the Euro Medic

project which feature a Samurai RCUE 40AG2 chiller.

Crossflow Director Padraig Hanvey says that the quality

of the Hitachi equipment, and the scope of the

applications catered for, perfectly complements the

engineering-based solutions it strives to offer its clients.

“With the professionalism and experience of our staff

and the high level of attention we pay to every detail of our

customers requirements”, says Padraig, “we continually

strive to find innovative technical solutions for the

design and installation of air conditioning systems, building

control systems and close control data centre

temperature management systems. We find that the

Hitachi range, coupled with the support services provided

from its Irish office, helps us realise this objective.”

Critical to this endeavour is the constant introduction of

cutting-edge products and systems such as the new

Samurai AG2B chiller range which enhances the precise

control of outlet water temperature across all

applications.

Ranging from 180 to 450HP, leading features of the

AG2B technology include:

Increased efficiency

– The

AG2B has increased its efficiency thanks to its worldrenowned

twin, screw compressor that uses a STAR

DELTA start up;

Reduced Footprint

AG2B achieves high cooling capacity in approximately 9%

smaller space than previous models thanks to air-side heat

exchanger size modifications and a refrigerant distribution

redesign;

Noise/energy reductions

Impressively low noise levels are delivered by inverterdriven

two-blade fans. The two blades increase air-flow

but lower power output, allowing for additional energy savings;

User-friendly and safety

The AG2B incorporates an easy-to-use touch LCD

panel display for effective servicing and maintenance.

In conclusion, Padraig Hanvey says: “We’re

delighted with this latest addition to the Hitachi

Samurai range of chillers. We are also confident that it

will prove critical in helping us secure further prestigious

projects into the future.”
