Cut energy waste at the source.

Making your building perform better: Pump optimization to power smarter HVAC systems.

Reduce electricity costs and improve cooling efficiency by replacing outdated chilled water pumps with tailored, high-performance solutions.

Why choose pump optimization services?

Improve HVAC performance and reliability

Be energy efficient and cut costs

Be eco-friendly and reduce CO₂ footprint

Avoid Delta T penalties

Extend equipment lifespan

Don’t let pumps drain your budget.

In many buildings, pumps are among the most overlooked energy consumers. However, if they are oversized, outdated or simply inefficient, they can silently drive up electricity costs and put a strain on your entire HVAC system. ista’s Pump Optimization service is designed to put a stop to this.

As part of our Energy Services Company (ESCO) offering, we help property owners and operators identify underperforming chilled water pumps and replace them with smarter, more efficient alternatives tailored to their building's actual needs. The result? Lower consumption, less waste and meaningful progress towards your sustainability goals.

We make pump optimization simple and effective.

How we find and fix energy waste in pump systems.

Every pump system has its own performance curve, and if this does not match the building’s actual demand, it results in energy wastage, increased wear and tear, and higher operating costs. That’s why correct sizing and configuration are so important.

In most cases, energy consumption accounts for the largest proportion of the life cycle costs of a pump system, given that pumps often run for more than 2,000 hours per year. In fact, around 20% of the world’s electrical energy consumption is used for pump systems.

At ista, we start by carrying out a pump audit or energy check. During this process, our experts assess your existing chilled water pumps to evaluate flow, demand and energy consumption. We then identify opportunities for optimization, whether through adjusting pump performance or replacing outdated equipment.

Smart pumping for greener buildings.

Our focus is always on HVAC applications, where pump performance plays a significant role in system efficiency. Modern pumps can adapt to real-time demand. Reducing flow by 20% can cut energy use by up to 50% in some cases. That’s a major win for cost control and sustainability efforts. Beyond energy savings, pump optimization helps reduce system strain, improve uptime, and extend the life of your equipment. In short: fewer surprises, more control.

By selecting the right pump type and control method, we help you strike the right balance between performance and cost, ensuring your system is built for efficiency rather than just operation.

Avoid Delta T penalties and improve compliance.

In the UAE, inefficient chilled water systems are not just a technical issue; they can also result in direct financial penalties. District cooling providers now monitor the temperature difference (Delta T) between the supply and return water temperatures. If the Delta T is too low, this indicates poor heat transfer and inefficiency, which is often caused by outdated or oversized pumps running outside their optimal range.

According to local regulations, including Dubai Executive Council Resolution No. (6) of 2021 and district cooling guidelines issued by the RSB (Regulatory & Supervisory Bureau, Dubai) and the Abu Dhabi Department of Energy, building owners may be penalized if their systems consistently underperform. ista can help you stay within performance thresholds by optimizing pump flow rates and ensuring proper hydraulic balance, thus avoiding penalties, improving energy efficiency and supporting regulatory compliance as part of your broader sustainability strategy.
