Saudi Arabia’s Standards Organization (SASO) updated the energy efficiency standard SASO 2663:2026 on May 10, 2026, mandating heat recovery functionality in all newly marketed washing machines. This regulatory shift is driving increased procurement of integrated heat-recovery modules for industrial chiller systems across the Kingdom’s home appliance manufacturing supply chain.

Regulatory Update: SASO 2663:2026 Enters Force

On May 10, 2026, SASO officially published the revised SASO 2663:2026 standard, which requires all new washing machines sold in Saudi Arabia to incorporate waste-heat recovery capability. The standard applies to products placed on the market after its effective date. As a direct consequence, manufacturers and suppliers of industrial冷水机组 (chillers) are seeing rising demand for add-on heat-recovery modules—specifically integrated units comprising plate heat exchangers and variable-frequency pumps.

Supply Chain Impact Across Key Roles

Export-Oriented Appliance Manufacturers

These firms must now redesign or retrofit washer production lines to integrate certified heat recovery systems. Compliance affects product development timelines, component sourcing strategies, and pre-market conformity assessment procedures—including SASO certification and energy labeling requirements.

Component Suppliers & Raw Material Procurement Firms

Suppliers of thermal management components—including plate heat exchangers, high-efficiency pumps, and corrosion-resistant piping materials—are experiencing intensified inquiry volume from OEMs. Material traceability, thermal performance validation under Saudi ambient conditions, and documentation alignment with SASO technical annexes are becoming critical selection criteria.

Industrial Chiller System Integrators

Companies specializing in chiller system engineering and assembly face expanded scope: they must now offer modular, plug-and-play heat recovery solutions compatible with both new chiller installations and retrofits in existing laundry or manufacturing facilities. Thermal integration testing and factory acceptance protocols are gaining prominence in tender evaluations.

Logistics & Certification Support Providers

Third-party conformity assessment bodies, SASO-accredited labs, and export compliance consultants report growing requests for pre-submission technical reviews, test planning for heat recovery efficiency (e.g., COP_HR verification), and bilingual documentation support aligned with SASO’s Arabic–English regulatory framework.

Strategic Priorities for Market Participants

Verify Module Certification Pathways

Heat recovery modules themselves—though not standalone appliances—must comply with SASO’s broader electrical safety and electromagnetic compatibility (EMC) requirements when supplied as part of an integrated chiller system. Firms should confirm whether module-level SASO Type Approval or system-level approval suffices under current interpretation.

Align Technical Specifications with SASO Annexes

The updated standard references specific test methods and minimum recovered heat ratios. Suppliers must ensure datasheets, IOM manuals, and tender submissions explicitly reference compliance with SASO 2663:2026 Annex B (thermal performance verification) and Annex D (durability under cyclic load conditions).

Adjust Procurement & Delivery Timelines

Given projected order growth exceeding 35% in H2 2026, lead times for precision-engineered components—especially custom plate heat exchangers with ASME BPVC Section VIII compliance—may extend. Early engagement with qualified Saudi-based distributors or local partners is advisable to secure allocation and manage customs clearance windows.

Prepare Documentation for Local Conformity Assessment

Documentation packages must include Arabic-translated technical files, third-party test reports (preferably from SASO-recognized labs), and evidence of material compliance with Saudi environmental regulations (e.g., RoHS-equivalent restrictions on heavy metals in pump housings and gasket compounds).

Industry Observation: Beyond Compliance to System Integration

Analysis shows this regulation marks a subtle but significant pivot—from viewing chillers solely as cooling assets toward recognizing them as hybrid thermal infrastructure. What deserves closer attention is how rapidly manufacturers are shifting from bolt-on heat recovery kits to co-designed chiller–washer thermal loops. Observably, the policy is accelerating adoption of modular, digitally controllable heat recovery units—not just for energy savings, but for predictive maintenance integration via embedded IoT sensors. From an industry perspective, the real bottleneck may not be technology readiness, but rather the capacity of local SASO-accredited testing labs to scale thermal performance verification throughput ahead of the 2026 year-end compliance surge.

Key Takeaway for Stakeholders

This update reflects Saudi Arabia’s broader strategy to embed circular thermal principles into consumer appliance standards—not merely to reduce grid load, but to incentivize localized value addition in HVACR component manufacturing and service ecosystems. While the immediate impact centers on chiller module demand, the longer-term implication lies in reshaping supplier qualification criteria toward thermal systems integration competence, not just component supply.
