How many pump installations in Dubai meets ASHRAE 90.1 ?

I have had the privilege to visit many chilled water plants in Dubai and surprised at how many sites are struggling with flow management.  It seems that many building operators are attributing little to no value to their circulating pump operation, concentrating on large ticket items such as chillers and air handling units to seek energy improvement. Unfortunately, chiller and/or AHU upgrade are often abandoned due to high capital cost to retrofit them.

As energy supply in the UAE is becoming an intensely hot topic (as everywhere else in the world), are we overlooking “low hanging fruits” by not tackling pumping cost?

Sure, the annual pumping cost is relatively small compared to chillers, but it still accounts for 30-35% of the plant total consumption. Furthermore, cutting in half the annual pumping cost does not require changing pumps or inverter, nor it requires piping modification and can be safely implemented without plant shut-down. This energy conservation measure is simple, low cost and without any operational risks.

Considering that every building in Dubai has large pumps operating 24/7 to circulate chilled water for its air conditioning needs, a concerted effort from the local engineering community to focus on that segment would go a long way to help building’s owners reducing consumption and contribute in a big way to the country energy objectives.


ASHRAE 90.1 suggest that power consumption of a variable speed circulating pump should be no more than 30% of its nominal Wattage at 50% of its flow. In other words, if your pump power consumption is 75kW at 100% flow, at 50% flow it should be no more than 22.5kW.

For the none techy guys, the flow is directly proportional to the cooling need, so in the summer months, more flow is needed because more cooling is needed, but during spring, fall and winter all pumps can be turned right down because less cooling is needed hence lower flow demand. This gives a very practical “yardstick” to assess plant saving opportunities.


If you just realize that your building pumping cost is too high, the good news is that ASHRAE laid-out all the information on how to deal with it and can be downloaded for $200 today! – www.ashrae.org – This provides the blueprint of remedial measures to improve pumping performance.

Want to save $200? – Simply send us a mail and we will share with you the common faults seen on-site that are contributing to excess pumping costs. dubai@orcivalpump.com

Ajdan residence block, another 3x large chilled water pumps

Orcivalpump completed the supply of 3x large chilled water pumps for the Ajdan residence building in the Bur Dubai area.

There are no small projects! We are very proud to have been involved in the supply of circulating pumps at the heart of the Ajdan residence HVAC system. The project execution required a very short leadtime for 3x large 45kW pumps. We were able to assist our client and help him complete his project on time and on budget.

We would like to thanks the project participants to entrust us with this project and look forward to many more.

Orcivalpump ready for take-off in Indonesia

Some time we get that call beyond our border…

That is exactly what happened when contractors in Indonesia called upon Orcivalpump to participate to the iFLY building project in Jakarta.

The iFly building in Jakarta is an indoor Skydiving leisure complex. This global US company has the largest network of indoor Skydiving facilities that deliver exhilarating sensations of flight without ever getting into an airplane.

Orcivalpump only played a small role in delivering HVAC tanks and accessories but it was great fun getting involved with these guys.

Orcivalpump scores at Al Wakrah Stadium

Orcivalpump secured the supply of multiple air separators for the Al Wakrah Stadium in Qatar.

The Al Wakrah stadium on the outskirt of Doha is due to become one of the center piece of the football World tournament in Qatar in 2022. This 40,000 seat sports complex is scheduled to open in 2019.
