High-end property developer requires complex climate rental solution

When a challenging job arises, our team is always quick to grab the opportunity to showcase the expertise and know-how that sets us apart from other providers.

Our engineers thrive under the pressure of having to think outside the box and it is these demanding situations that allow us to demonstrate our true capability.

In the summer of 2021, Andrews Sykes Climate Rental was approached by an upmarket property development company after they encountered issues with maintaining a comfortable temperature inside one of their luxury show apartments.

Conditions inside were considered completely unsatisfactory and there were fears from our client that the high humidity and excessive warmth could be extremely off-putting to potential buyers.

The apartment was located on the eighth floor of the building but access issues meant that any cooling equipment could not be sited any higher than the fourth floor. Because of this, our engineers were tasked with designing a suitable heat exchanger that would overcome the pressure loss incurred by a long chiller water pipe network.

We proposed two 100kW air cooled chillers along with a plate heat exchanger and buffer tank, before ensuring that our client was receiving sufficient flow through their permanent fan coil units. In doing so, we were able to guarantee that the necessary cooling capacities were uniformly achieved in all rooms.

Despite the obvious complexities, our engineers were able to implement a perfect solution which remains in place on an extended rental contract!

Andrews provides chiller installation for high-rise town in Downtown Dubai

Given the demands of our industry, the expertise and service capability of Andrews Sykes Climate Rental is routinely put to the test by expectant customers. Time and time again, we deliver.

One of the UAE’s largest civil contractors required our assistance with implementing a small scale district cooling plant, which was needed until a permanent installation could be put in place.

Typically, delays with district cooling systems can cost developers millions of dollars in the latter stages of a project – and that was no different in this case!

The building’s interior, wallpaper, painting, decor and flooring are all reliant upon particular conditions, with low temperatures and good ventilation essential.

Once we were selected as the development’s temporary district cooling provider, it was imperative that we could configure a solution that would deliver a supply of chilled water to the building.

We achieved this by installing two 700kW chillers, coupled with heat exchangers matching a 1,400kW cooling capacity.

The impeccable service of our engineers was greatly appreciated by a well-known customer, whose excellent proposal worked perfectly until Empower’s permanent chilled water system was ready to be connected.

In fact, so efficient and professional was our team, that the client has since expressed an interest in procuring our assistance with a similar project for a multistorey residential project nearby.

Premium hotel kept cool by chiller and ventilation dual solution

For the last three years, Andrews Sykes Climate Rental has provided a well-known luxury hotel in the UAE with temporary cooling and ventilation. This seasonal requirement is an annual project that tends to occur in either July or August, when average temperatures regularly exceed 43°C.

In order to optimise space, our client had converted part of the hotel’s basement into a temporary office and subsequently required assistance with creating a more appealing working environment. Unsurprisingly, conditions beneath ground were even warmer than the outdoor ambient temperature, so a climate control arrangement was desperately needed!

Our local expert visited site to assess the requirement and in doing so, uncovered a number of hot spots. It was decided that a single 380kW chiller would deliver the correct cooling capacity for the intended area, and this was connected to several air handlers to help distribute conditioned air more evenly throughout the application. This was further supported by a series of FV600 and FV900 ventilation fans, which were used to increase airflow and maximise the circulation of cool air.

Thanks to this complex but effective configuration, we were able to dramatically reduce both the temperature and humidity to much more desirable levels. By reacting quickly to spec and install a combination solution in a matter of hours, we were able to maintain our excellent relationship with a valued and longstanding customer.

Etihad Rail contractors follow up dewatering pump rental with ventilation arrangement

With Stage Two of the UAE’s generational railway network project now well underway, a need to support construction operations with ventilation equipment has led to the involvement of Andrews Sykes Climate Rental.

Engineering work has commenced at various locations, including several long and narrow tunnels that will eventually permit freight and passenger trains to pass through.

Naturally, these enclosed applications require a constant circulation of clean, fresh air to ensure those working inside have an adequate source of safe air to breathe.

Machinery utilised within the tunnels will produce fumes and dust, so it is essential that temporary equipment is deployed to prevent engineers suffering any ill effects of their working environment.

For this reason, we have installed our high capacity FV1800 ventilation fans at the tunnel entrance to ensure that a constant supply of clean air is delivered inside.

Although simple in terms of their functionality, these large fans are specifically designed for tight, longitudinal tunnels such as those seen on the Etihad Rail development. A single unit will deliver massive airflows of up to 38,000m³ per hour, making it one of the most powerful ventilation fans available on the market.

At present, there is only a requirement for delivering fresh air but as progress is made and the track begins to take shape, there will be an additional need for fans to be used on extraction mode.

We are delighted with our contribution to one of the regions’ most ambitious infrastructural schemes and have demonstrated both our pumping and HVAC capabilities during our involvement.

Andrews providing cooling for Dubai campus of UK-based university

With high temperatures and uncomfortable conditions threatening to delay a major construction project in the Middle East, Andrews Sykes moved quickly to devise and implement a climate control rental solution.

The company overseeing the job was concerned about the implications of a potential postponement, prompting them to enquire about how we could assist them. Our sponsors, Khansaheb Civil Engineering, are one of the most established companies in the region and have further enhanced our reputation as industry leaders.

One of our local experts liaised directly with the customer and reassured them that a temporary air conditioning arrangement would sufficiently protect workers by drastically reducing high temperatures on site.

The majority of those working on the project were based in confined spaces underground, meaning there was little ventilation and no cooling relief.

To address this, our team proposed a 300kW chilled water air handling unit which would tackle both the excessive temperature and humidity. The configuration comprised of three 100kW high ambient air-cooled chillers which helped significantly improve conditions.

Prior to our arrival, the temperature was recorded as being 37⁰C, with relative humidity at 70%. Once the equipment was installed, temperatures were maintained at 25⁰C while relative humidity was limited to 55%.

Due to shifts split across 12-hour periods, our equipment was continuously operational – even through the night – with labourers constantly working to ensure the project was completed on time.

The construction manager was greatly appreciative of our efforts, and our kit is routinely supported by engineers revisiting site to ensure our cooling system still performs as expected.

Andrews helps commission HVAC system inside flagship tugboat

For many years, we have been well-known for our ability to adapt unique solutions for clients across a full range of industries.

Our expertise has allowed us to work on many of the more unusual HVAC and pumping developments, including commissioning the climate control system on board a large tugboat recently built in the UAE.

In this instance, our client specifically sought out the assistance of a trustworthy and reputable HVAC supplier – Andrews Sykes Climate Rental.

Initially designed for sea water to condensate the water-cooled chiller, the water’s excessive temperature meant that the condenser would not perform as expected and thus an alternative solution was required.

Instead, our engineering team installed a 100kW air cooled chiller along with a mixing tank to supply colder water to the tugboat. This configuration prevented the chiller from failing as a result of the inlet water being too warm, with the mixing tank tailored to ensure the water temperature was properly maintained.

With the temperature setting and mixing water temperature kept constant, the client was able to test and commission their new HVAC system without any further complications.

The technical knowhow of our engineers was a key component of this job and helped a concerned customer address an issue that could have prevented the tugboat from being utilised.

Following the completion of the project, they gave us a positive testimonial thanking us for the service we provided. A spokesman for the company said: “We would like to thank Andrews Sykes Climate Rental for assisting us with a temporary chilled water system during testing and commissioning of our new tugboat system. We look forward to working with you in the near future at the dry docks and Dubai Maritime city.”

Air conditioning rental keeps workers cool during tunnel construction

At Andrews Sykes Climate Rental, we are trusted by construction companies across the Middle East to provide bespoke HVAC solutions tailored to their specific requirements.

In August, we were approached by one of the industry’s big names and asked to recommend a high performance air conditioning system to keep workers cool on a tunnel construction development.

The idea was to supply some cooling relief to engineers based at the bottom of the structure, with their constant presence on site essential to ensure that the intended passageway could be formed, and any debris removed.

After attending site to specify a potential solution, our engineers assured the customer that a practical air conditioning rental arrangement could be quickly up and running.

Specifically desiring reliable, modular units, the client remarked that the confidence and knowledge of our experts had been demonstrated on previous dealings and was greatly reassuring to them.

Our ability to provide a full turnkey solution – in addition to overseeing the installation and any potential maintenance – was what convinced the customer to use our services.

Two HPAC45 air conditioning units were subsequently dispatched to site and deployed in an identical fashion on two separate openings, delivering high volumes of comfort cooling to contractors working below ground level.

Popular due to their suitability for a range of multi-purpose schemes, our HPAC45 units are known for their efficiency and aptitude for noticeably reducing temperatures within minutes of operation.

High capacity cooling arrangement protects workers at iconic Dubai location

For a second successive year, Andrews Sykes Climate Rental was entrusted with providing a construction site with temporary cooling on the eye-catching artificially formed cluster of islands at Palm Jumeirah in Dubai.

The client approached us last summer looking for a chiller rental solution to keep workers cool, with seasonal temperatures regularly exceeding 50⁰C.

We were tasked with making conditions more comfortable within an underground car park area where site operators were undertaking their daily duties, necessitated by high levels of relative humidity and ambient temperatures constantly in the mid-fifties.

Our customer was looking for equipment to cool multiple condensers which were running to service a designated office area. Having assessed the application and the unique variables involved in this job, our engineers proposed the deployment of a 384kW chiller combined with air handling units and internal ducting to ensure cool air was evenly distributed throughout corridors.

The layout of the building restricted the air circulation in certain areas, prompting us to use ten ventilation fans to ensure cool air was dispersed around identified hot spots.

By taking this step, we were able to reduce temperatures by more than 20⁰C, safeguarding the compressors and eliminating the potential for any breakdowns that could affected the internal cooling configurations already in place.

Andrews Sykes Climate Rental provides low temperature chiller for process cooling application

For many years, Andrews Sykes Climate Rental has enjoyed an excellent reputation for our ability to devise and implement temporary HVAC solutions whenever our customers require.

Our strong standing in the Middle East has enabled us to work with some of the region’s biggest organisations, including the UAE’s largest food processing company.

On that occasion, the client wished to reduce the ambient temperature of their premises down to 5⁰C from 36⁰C and minimise the amount of water vapour present in the air. To achieve this, we designed and supplied a low temperature chiller configuration with a cooling capacity that exceeded 2MW. We also supplied a number of air handling units to ensure even distribution of cold air inside, along with multiple 90kW heat pump units.

For this configuration to operate effectively, dehumidified air of approximately 100,000CMH was required. In order to reduce moisture content in the atmosphere, we first needed to increase the air temperature to 45⁰C. Our design team proposed a system using our reliable air-cooled low temperature chillers with VFD-driven air handling units and state-of-the-art 90kW DX heat pumps.

Our solution was expected to be in constant operation, necessitating the integration of a large glycol water mixture buffer tank to ensure the chiller would not be starved of fluid in the unlikely event of a leak or evaporation. By doing this, we eliminated the need for human intervention as the system was capable of safely operating unattended.

With the client’s peace of mind an ongoing consideration, we arranged for an engineer to conduct routine check-ups to ensure our temporary solution was performing as expected throughout the duration it was on hire.

As such, we are very happy to report that the customer was greatly appreciative of our solution and the professionalism of our site team following the project’s successful completion.
