Bitzer pioneers high-reliability compressors for industrial refrigeration and HVAC. The Semi-Hermetic Piston Series (0.5-100HP) achieves a 20% higher COP through patented valve plates, supporting evaporation temperatures of -40°C with R22 and down to -70°C with R507. The Oil-Injected Screw Compressors (50-140HP) enable 15-100% stepless capacity control via IDV technology, reducing part-load energy consumption by 30% for applications such as chillers and rooftop units. Furthermore, the Ammonia Screw Series (e.g., OS.A95) uses a natural, zero-GWP refrigerant and features automatic Vi regulation, making it an ideal solution for freezing plants and marine systems.

We provide Benford Brewing with comprehensive industrial compressor technical support and maintenance services, focused on ensuring the stable operation of their brewing lines. Through regular inspections, rapid troubleshooting response, and preventative maintenance, we keep their refrigeration systems, bottling equipment, and pneumatic controls operating efficiently, which guarantees consistent craft beer quality.
Certificates & Compliance: Refrigerant Eco-Friendliness: NH₃ (GWP=0)/R290 (GWP=3), compliant with EPA SNAP Rule 23Carbon Footprint: Annual CO₂ reduction of 142 tons (equivalent to planting 3,200 trees)Certifications: USDA Organic + ENERGY STAR Refrigeration System
Brewing Impact: Dry-hopping at -1°C±0.2°C → α-acid retention >93% (vs. 76% conventional)
Technical Basis: CO₂/NH₃ cascade system has a COP of 4.2 compared to a single-stage system of 2.8. The system features PID-controlled glycol valves and redundant compressors, with temperature control within ±0.3°C during critical metabolic periods (to avoid heat stress). The R290 turbine plate commutation speed is 3.5 m/s (compared to a conventional 1.2 m/s).
CO₂/NH₃ Cascade System (-45°C): Low-temperature stage: CO₂ (evaporation at -45°C) rapidly cools fermenters, addressing yeast heat stress. High-temperature stage: NH₃ (-10°C) cools malt, a GWP=0 environmentally friendly working fluid. Energy efficiency mechanism: Staged compression reduces overheating losses, achieving a COP increase of 40%.Solar-Assisted Absorption Chiller: Heat recovery: Solar panels (120 square meters) drive lithium bromide chillers.Free cooling capacity: ≥15% cooling capacity is provided in summer, and the utilization rate of Nanka's sunlight resources reaches 83%.
Precision Dry-Hop Chamber (-1°C±0.2°C): Aroma Retention: -1°C ambient temperature suppresses monoterpene volatilization, achieving >93% alpha-acid retention.Control Solution: Dual compressor hot standby + electronic expansion valve PID control.R290 Turbo Plate Exchanger: Turbulent design: Plate corrugation angle increased from 60° to 30°, increasing flow rate by 192%.Safety measures: Explosion-proof motor + infrared leak sensor, compliant with NFPA 36 standards.
Brewery Energy Management Platform: Load Forecasting: Dynamically adjusts cooling capacity based on fermentation curves and weather forecasts.Fault Prediction: Vibration sensors provide early warning of compressor anomalies (≥72 hours in advance).Remote Operation and Maintenance: 80% of faults are diagnosed in the cloud, reducing on-site service costs by 40%.

Here at A&S Aerodynamic, we offer a wide range of refrigeration compressors from various brands and models. Our products are sourced from reputable brands in the industry, so you can be sure they’re made to fit OE specifications.
1. Before shipping, we will send you photos of the actual product for your confirmation ( eg. nameplate, appearance, and report).
2. The product comes with a 1-year manufacturer warranty policy and 3-year in-house warranty.
3. If the product is damaged during transportation or cannot be repaired due to non-human-caused within 1 year, no return, we will directly refund or resend the new product.
4. For select items, we will include a repair kit ( Special Needs Customer Service ).
5. Enjoy a worry-free experience throughout the entire process. Feel free to request quotes and place orders with confidence, we will provide 5-star service until you are satisfied.
6. Shipping and Taxes: See Quotation.
Need your compressors as soon as possible? Don’t worry; our warehouses are strategically located across the country to ensure fast, efficient shipping. Our primary strength lies in supply capability. Whether it's OEM manufacturing or global inventory searches—from components to complete units—we can match your needs with the nearest partner's inventory for rapid delivery. Our global alliance enables transactions at wholesale agency rates. Welcome aboard! Cheers!!
The Nameplate is Key: The model number alone is sometimes insufficient. We request a clear photo of the manufacturer’s metal nameplate. This confirms the specific Series, Voltage, and Bill of Material (BOM) number.
Refrigerant Verification: You must confirm the gas type (e.g., R134a, R404A, R290, or R410A). Using the wrong refrigerant in a compressor designed for a different gas will lead to immediate failure and void the warranty.
Voltage & Frequency Check: Global power grids vary. Whether you need 115V/60Hz (USA), 220V/50Hz (Europe/Asia), or 3-Phase 380V, this must be explicitly confirmed during the inquiry stage to prevent electrical burnout.
Application Matching: We verify if your application requires LBP (Low Back Pressure for freezers), MBP (Medium), or HBP (High Back Pressure for A/C and chillers). Installing an LBP compressor in an HBP application will cause the motor to overheat.
Performance Benchmarking: Before shipment, units undergo rigorous testing for volumetric efficiency, motor amperage draw, and noise levels
The Test Report: For peace of mind, we can provide a Quality Inspection Report or a video of the compressor under load test, proving it holds pressure and operates within factory specifications before it leaves our facility.
Spot Buy (Ready Stock): For urgent repairs, we leverage our global inventory of popular brands (Tecumseh, Copeland, Danfoss) to offer "2nd-Day Dispatch" on common models.
Batch Production (OEM Orders): For distributors or appliance manufacturers requiring 50+ units, we schedule a production run. This typically requires a 2-4 week lead time but offers significant cost savings.
Condition Clarity: We clearly distinguish between "Factory New" (fresh production) and "New Surplus" (older stock). We allow you to choose based on your budget and warranty requirements.
Robust Crating: We do not use standard cardboard for international freight. All compressors are bolted to a pallet and sealed in fumigated wooden crates compliant with ISPM 15 standards for global entry.
Upright Transport: Compressors must remain upright to prevent oil from entering the compression chamber (which causes "liquid slugging"). Our packaging includes "This Side Up" shock sensors and indicators.
Customs & Documentation: We handle the complex paperwork, including Commercial Invoices and Certificates of Origin, ensuring your goods clear customs smoothly whether shipping via DHL Air Express or Sea Freight to any port in the world.
