Biogas Chiller, Biogas Booster & Pretreatment Skid (GC / GF / SKID)
EnvironTec provides both standalone GC Series Biogas Chillers (GC-300 to GC-5000 with 10.7 kW to 170.0 kW cooling capacity), GF Series Particulate Gravel Filters (GF-200 to GF-2000), and fully integrated SKID Series Pretreatment Systems (combining filtration, +4°C dehydration chilling, demisting, reheating, and ATEX VFD booster blowers on a single SS304 frame). For a 500 m³/h project, we select Model GC-650 (23.2 kW cooling capacity, DN150) + GF-650, or a turnkey SKID-650 / SKID-Custom-Made package.
9 standard chiller sizes with exact cooling capacity from 10.7 kW to 170.0 kW.
SS304 gravel & ceramic particulate filtration (3–8 μm) protecting downstream blowers.
Tailored all-in-one Chiller + VFD Booster + Reheater skid for CHP & RNG plants.
Full explosion-proof refrigeration compressor, VFD cabinet & anti-vacuum interlock.

Engineering & Sizing FAQ
Q: How is the cooling capacity (kW) of a GC Biogas Chiller matched to biogas flow rate?
Cooling load depends on cooling raw biogas from 35–40°C (100% water-saturated) down to +4–10°C, including both sensible gas cooling and the latent heat of condensing water vapor. In our 2026 standard catalog, GC-300 provides 10.7 kW cooling, GC-650 provides 23.2 kW (ideal for 500–650 m³/h), GC-1000 provides 35.7 kW, and GC-2000 provides 71.4 kW. For high-ambient tropical regions (e.g., Southeast Asia POME plants), we offer GC/SKID-Custom-Made with tropicalized condensers.
