Why This Market Is Changing

The HVAC sector is undergoing a rapid shift driven by:

  • Future Homes Standard (FHS) moving new-builds to low‑carbon heating
  • Boiler Upgrade Scheme (BUS) supporting residential retrofit
  • Accelerated transition to R290/low‑GWP refrigerants
  • Tighter acoustic, efficiency and aesthetic expectations
  • Pressure for improved sustainability and recycled content

These changes require redesigned enclosures that deliver safety,
performance and manufacturability.

R290 Ready Enclosures

Market Pressures OEMs Are Facing

  • R290-specific enclosure demands: venting, partitioning, spark-safe separation
  • Acoustic performance: panel resonance, airflow noise, vibration
  • High assembly minutes and slow service operations
  • Need for UL94 V‑0, glow‑wire and UV‑stable polymers
  • Compressed development timelines for regulatory milestones
  • Dependence on overseas tooling slowing ECNs and release cycles

Standing still is not a penalty risk but a commercial one: slower certification, higher assembly cost, and
reduced competitiveness.

How PEP Helps OEMs Deliver R290 Ready Products

Accelerated 2‑Week DFM/VA Sprint

  • Reduce fasteners using clip‑fits and quarter‑turns
  • Integrate airflow baffles and anti‑resonance ribs
  • Engineer safe vent paths and partitions for R290 compliance
  • Optimise wall thickness, ribs and draft angles
  • Improve sealing with precise gasket paths
  • Provide PPAP-ready documentation

UK Tooling & Moulding
