<\/span><\/div><\/span><\/div><\/div><\/div>\n\n<\/div><\/div>Modernization with heat pump and optimized air flow<\/h2><\/div><\/div><\/div>HARTER retrofits existing drying systems with Airgenex\u00ae or Drymex\u00ae technology: heat pump-based condensation drying in a closed air circuit, precise air flow, and modern control technology. This allows you to increase quality and throughput, reduce energy and CO\u2082 costs, and remain independent of the indoor climate \u2013 with predictable downtime. This avoids the costs of a complete new purchase and significantly reduces conversion and downtime. A retrofit is particularly recommended for very large, mostly fully automated systems; for smaller applications, a complete new system from HARTER is often the more economical and process-reliable solution.<\/p>\n<\/div><\/div><\/div>
