Altecnic HIU passes 'Best Practise' criteria in UK BESA testing

Oct 31, 2025
1 min read

Altecnic’s SATK32107 heat interface unit (HIU) has delivered industry-leading results in the latest BESA UK HIU Test Regime, passing more individual ‘best practice’ criteria than any other HIU currently tested in the UK, the company said. 

The BESA test is recognised as the benchmark for assessing HIU performance in the UK, independently evaluating efficiency, reliability, and network suitability. Altecnic’s SATK32107 passed all four indirect modules and recorded eight best practice outcomes, the highest to date among all tested HIUs in the UK market. 

This demonstrates the unit’s performance under real-world conditions and its alignment with the CIBSE CP1 (2020) and HNTAS standards. The results confirm that the SATK32107 not only meets today’s expectations but is futureproofed for evolving UK performance benchmarks.
