Saudi SABER Cooling Tower Rule Adds EN 13859-2 Test

On July 1, 2026, a new compliance requirement takes effect for cooling tower products under Saudi Arabia’s SABER energy efficiency certification. Based on an urgent notice issued by SASO on June 18, the upgrade adds a mandatory EN 13859-2 thermal loss coefficient test alongside the existing flow and noise testing, making this a practical concern for exporters, manufacturers, certification teams, and delivery planners involved in shipments to the Middle East.

What changes on July 1

The confirmed change is that cooling tower products applying for SABER energy efficiency certification must, from July 1, include testing for a thermal loss coefficient under EN 13859-2, with a required result of no more than 0.35 W/(m·K).

According to the provided event summary, this new item is added on top of the previously required flow and noise tests. The same summary also states that registered in-stock models that did not complete the additional testing by June 30 will automatically lose validity.

The timing is especially notable because the notice was issued by SASO on June 18, leaving a short transition window before the July 1 implementation date.

Where the immediate pressure is likely to appear

Export execution and existing model filings

From an industry perspective, the first area affected is likely to be export execution tied to already registered models. Because the summary states that in-stock filed models would automatically become invalid if supplementary testing was not completed by June 30, trade teams need to pay close attention to whether previously usable registrations can still support shipment and customs-related documentation workflows.

Manufacturing and product compliance coordination

Manufacturers are likely to feel the impact through compliance coordination rather than through a simple paperwork update. Analysis shows that the addition of a new thermal performance indicator can directly affect document readiness, internal testing arrangements, and the timing of model release for the Saudi market.

Supply chain and delivery scheduling

Supply chain service providers and order management teams may also face short-term disruption. Observably, when a mandatory test item is inserted with a near-term deadline, the main business pressure often appears in shipment sequencing, handover timing, and communication between factory, exporter, and buyer over whether a specific model remains valid for delivery.

Buyers and project-side procurement decisions

For procurement parties and downstream users, the key issue is not only product selection but also certification continuity. What deserves closer attention is whether the model under procurement still holds valid filing status after the rule change, especially for orders linked to fixed delivery windows.

What companies should watch now

Check model status against the June 30 cutoff

The most immediate practical task is to distinguish between models that completed the supplementary test before June 30 and those that did not. This matters because the provided information explicitly links that deadline to the continued validity of existing registered models.

Review whether technical files are complete for the new item

Companies involved in certification submission should focus on whether the EN 13859-2 thermal loss report is already available and whether it aligns with the required threshold of no more than 0.35 W/(m·K). In practice, this is a documentation and timing issue as much as a technical one.

Separate official rule text from business assumptions

Analysis shows that businesses should be careful not to treat internal expectations or market rumors as final operational guidance. The confirmed facts are limited to the urgent notice date, the July 1 upgrade, the added mandatory test item, the threshold, and the stated consequence for models missing the June 30 supplementary test deadline.

Prepare customer and delivery communication

For teams handling Middle East orders, current attention should be on delivery risk communication, document review, and contingency planning around affected model registrations. This is particularly relevant where shipment commitments depend on previously filed models.

How this development is best understood

Analysis shows that this is more than a routine adjustment to certification paperwork, because the new requirement is tied to a measurable thermal loss threshold and a very short implementation window. At the same time, it should not automatically be read as a full market reshaping event based on the information currently available.

It is more appropriate to understand this as an immediate compliance tightening with direct short-term operational consequences, especially for cooling tower exports already linked to existing SABER filings. Observably, the strongest signal in the current information is not long-range market forecasting, but the need for quick verification of certification validity and delivery readiness.

Why the industry should keep following it

The current significance of this update lies in its direct connection between a new mandatory test and the validity of registered models. For the industry, the practical takeaway is that certification changes can move quickly from technical requirement to shipment risk when transition periods are short.

At this stage, it is more appropriate to understand the development as a near-term compliance and fulfillment issue with wider implications still requiring observation. Any broader judgment about long-term market impact would need more confirmed information than is provided here.
