EquinoX is a high performing AHU that is ErP and Part L compliant. It rates highly against EN1886:2007 guidelines, offering additional reassurance of quality and performance. Delivering controllable, on-demand heating, cooling and heat recovery, it is a highly efficient AHU, with an extended life cycle due to high performing materials that deliver both insulation and strength.

Performance according to EN1886: 2007 rated as:

  • T2 (0.5 < U ≤ 1) thermal transmittance class
  • TB1 (0.75 ≤ kb < 1.00) thermal bridging class
  • L1 (< 0.22 l x s-1 x m-2) casing air leakage class
  • D1(< 4 mm x m-1) mechanical strength
  • F9 (< 0.5 %) filter bypass leakage



The typical insulation is provided by using 50 mm rock wool with 70kg/m³ density.


Service and maintenance of EquinoX is simplified with the provision of easy access doors, ensuring all areas of the unit are easy to reach. Inner edges and corners are rounded to minimise the accumulation of dirt and the use of composite materials in the frame offer an extended life cycle.
