NOTES: (1) All air flow rates rated at +3°C dewpoint, 1 bar(a), 20°C inlet temperature conditions. (2) ISO 8573-1:2010 classification requires appropriate pre and post filtration — see individual product datasheets for complete system class achievable. (3) R513A is a low-GWP HFO/HFC blend (replacing R134a). R452A used in subfreezing GDMT series. R407C used in HP45-50 barG GDDF-HP models. (4) Desiccant dryers achieving −40°C or −70°C PDP are suitable for critical process, instrument air, and pneumatic control applications. (5) Heatless desiccant dryers consume approximately 15–20% of treated air volume for purge/regeneration. Heated blower (GDHB-TLS) eliminates purge loss.
