• Analyst Opinion
  • Shambhu Nath Jha, Principal Consultant at Fact.MR, says 'The liquid desiccant HVAC systems market is an emerging technology category with high growth potential driven by the fundamental inefficiency of conventional HVAC dehumidification in humid climates. The market is still in its early commercialization phase, with adoption concentrated among energy-conscious building developers, healthcare facilities, and projects with access to low-cost thermal energy for desiccant regeneration. The companies that will lead this market are those that simplify system design, reduce installation complexity, and build service networks that give building operators confidence in long-term system performance. The technology case is strong, but commercial success depends on reducing the gap between early-adopter projects and mainstream building specification.'
