In the published 2,000 m2 comparison, ten RDF-08C units (52 kW total) replace twenty 5 HP cabinet air conditioners (80 kW), saving about 33,600 kWh over a four-month cooling season. ## Why the RDF-C low-carbon platform - **Evaporative pre-cooling + compressor stage.** A direct-expansion coil assisted by evaporative cooling reaches rated capacity with roughly one third less compressor power than conventional cabinet air conditioners. - **Fresh-air positive pressure.** One-to-one indoor/outdoor systems continuously bring in filtered outside air, holding dust and odors out under slight positive pressure. - **Documented savings.** Manufacturer comparison for a 2,000 m2 workshop: twenty 5 HP cabinet units draw 80 kW; ten RDF-08C deliver the same cooling at 52 kW - about 33,600 kWh saved over a four-month cooling season. - **R410A, digital scroll, intelligent control.** Cooling and dehumidification modes, WiFi/APP control and 53-68 dB(A) operation depending on model. - **The energy-case benchmark.** The 08C is the model quoted in the manufacturer comparison that anchors the range's savings claim. - **Quiet for its class** at up to 55 dB(A), suitable for occupied production and commercial floors. ## Technical specifications | Model | Rated cooling capacity | Rated power input | Airflow | Power supply | Refrigerant | Noise dB(A) | Weight indoor+outdoor (kg) | Indoor unit (mm) | Outdoor unit (mm) | Recommended area | | ----- | ---------------------- | ----------------- | ------- | ------------ | ----------- | ----------- | -------------------------- | ---------------- | ----------------- | ---------------- | | RDF-05C | 17 kW | 3.7 kW | 5,000 m3/h | 380V/50Hz | R410A | <=53 dB(A) | 158 + 104 kg | 790x560x1860 mm | 780x780x1490 mm | 150-200 m2 | | RDF-08C | 28.5 kW | 6.5 kW | 9,000 m3/h | 380V/50Hz | R410A | <=55 dB(A) | 170 + 105 kg | 790x560x1860 mm | 780x780x1490 mm | 200-250 m2 | | RDF-10C | 35 kW | 6.8 kW | 10,000 m3/h | 380V/50Hz | R410A | <=68 dB(A) | 240 + 130 kg | 900x530x1990 mm | 890x890x1460 mm | 250-350 m2 | | RDF-12C | 53 kW | 10.3 kW | 12,000 m3/h | 380V/50Hz | R410A | <=68 dB(A) | 320 + 130 kg | 920x530x2140 mm | 890x890x1460 mm | 350-450 m2 | Rated capacity under nominal conditions; effective coverage depends on ceiling height, heat load, insulation and fresh-air requirement. One-to-one indoor/outdoor configuration. ## Where the 08C is specified Assembly lines, garment and electronics workshops, packaging halls, staff areas adjacent to process heat and mid-size commercial kitchens: anywhere requiring 25 kW-class cooling with continuous fresh air. The one-to-one indoor/outdoor split keeps refrigerant pipe runs short and installation conventional for any HVAC crew. ## Backed by a specialist air-treatment manufacturer - 20+ years focused on evaporative cooling and large industrial fans; National High-Tech Enterprise and CRAA-listed manufacturer. - Deputy Director Unit of the national evaporative-cooling industry committee, with 40+ patents and self-developed, patented molds. - Product liability underwritten by CPIC (policy ADNGD0207121Q000109N); type-test, protection-grade and CE motor-conformity documentation supplied with export orders. - RDF equipment is published in service with automotive, food and electronics manufacturers including SAIC-GM-Wuling, FAW-Volkswagen, GAC Toyota/Honda, PepsiCo, Foxconn, Panasonic, Gree, Midea and Haier. ## Ordering the RDF-08C low-carbon fresh-air air conditioner (28.5 kW, 200-250 m2) - **MOQ:** 10 units - **Lead time:** 10 units ex stock; 100 units in about 7 days; 500 units in about 20 days (larger orders confirmed case by case) - **Trade terms:** FOB Shenzhen - **Payment:** T/T - 35% deposit, 65% balance paid before shipment - **Warranty:** 2-year warranty on the complete unit per the factory's warranty policy: motor 2 years, controller 2 years.

Evaporative pre-cooling of fresh air plus a direct-expansion compressor stage reaches rated capacity with roughly one third less compressor power than conventional cabinet units. The documented 2,000 m2 case uses 52 kW instead of 80 kW - about 33,600 kWh saved over a four-month season. ### Does it bring in outside air? Yes - unlike a split or cabinet AC that recirculates, the RDF-C range continuously supplies filtered fresh air at slight positive pressure, pushing heat, dust and odors out. It is a ventilation and IAQ upgrade as well as cooling. ### What refrigerant does it use? R410A across the range. No lower-GWP refrigerant option is listed in the current 2026 catalogue. ### How is it controlled? One-to-one indoor/outdoor configuration with intelligent control and WiFi/APP operation; group/BMS options for multi-unit projects protocol details and overseas APP availability are confirmed at quotation stage. ### Is the 33,600 kWh saving independently certified? It is the manufacturer's published engineering comparison (20x 5 HP cabinets at 80 kW vs 10x RDF-08C at 52 kW over a four-month season). We quote the arithmetic transparently and re-run it on your tariff and running hours rather than treating it as a guarantee. ### What area does one 08C cover? 200-250 m2 at normal industrial heat load; high glazing, cooking or dense machinery reduce this, and the 10C (35 kW, 250-350 m2) is the step up. ## Related products - [RDF-05C Low-Carbon Air Conditioner](/product/low-carbon-air-conditioner-rdf-05c/) - [RDF-10C Low-Carbon Air Conditioner](/product/low-carbon-air-conditioner-rdf-10c/) - [RDF-08FC Low-Carbon Air Conditioner](/product/low-carbon-air-conditioner-rdf-08fc/) - [RDF-08FS Low-Carbon Air Conditioner](/product/low-carbon-air-conditioner-rdf-08fs/) ## More from TierCooling - [View installed project references](/projects/) - [About the manufacturer](/about/) - [All products in this category](/product-category/low-carbon-air-conditioners/) ## FAQ ### What is a low-carbon air conditioner? An air conditioning line engineered around energy efficiency - reducing electricity use per unit of cooling compared with conventional units, which lowers both running cost and operating emissions. ### Where are low-carbon air conditioners used? They suit spaces needing precise temperature control - offices, control rooms and production areas - especially sites pairing them with HVLS fans or evaporative cooling for a lower-carbon overall system. ### Can they work together with HVLS fans or evaporative coolers? Yes. Hybrid setups are common: airflow from HVLS fans improves perceived cooling and lets air-conditioning setpoints rise, while evaporative units pre-cool ventilation air in suitable climates. ### Where can I find specifications for each model? Each product page carries its specification table; model-level details such as capacity, power supply and options are confirmed during quotation against your site requirements.
