RISAN RS-125V-II Two-Stage Compression Screw Air Compressor

Higher Efficiency. Greater Energy Savings. Built for Heavy-Duty Performance.

The RISAN RS-125V-II Two-Stage Compression Screw Air Compressor is engineered for industries that demand continuous operation, high efficiency, and significant energy savings.

With advanced two-stage compression technology, this model delivers superior performance compared to conventional single-stage screw compressors, making it an ideal solution for energy-conscious businesses.

🔍 Product Overview

Two-stage screw air compressors combine the benefits of:

• Simple and robust structure
• Flexible installation
• High operational efficiency

More importantly, the RS-125V-II is designed to maximize energy savings and performance, even under demanding working conditions.

⚡ Key Energy Saving Benefits

1. Reduced Bearing Load & Higher Volumetric Efficiency

The two-stage design distributes compression work more evenly:

• Reduces mechanical load on bearings
• Improves volumetric efficiency
• Enhances overall machine reliability

👉 Result: Longer lifespan + more stable operation

2. Superior Performance Under Partial Load

Unlike traditional compressors, the RS-125V-II maintains high efficiency even when operating below full capacity.

• Optimized for variable demand environments
• Minimizes energy waste during low usage

👉 Result: Consistent energy savings across all operating conditions

💰 Proven Energy Savings

• Save up to 15% energy compared to standard single-stage screw compressors
• Based on 8000 operating hours per year
• Potential savings of up to USD 28,000 annually on electricity

👉 A powerful investment with fast ROI for industrial users

🚀 Core Advantages of Two-Stage Compression

1. Two-Stage Compression Reduces Power Consumption

By dividing compression into two stages:

• Lowers compression ratio in each stage
• Reduces unnecessary energy loss caused by friction and heat
• Requires less power compared to single-stage compression

📌 In real-world operation, multi-stage compression is more efficient due to reduced “wasted work” from mechanical losses.

2. Intermediate Oil Cooling for Higher Efficiency

The RS-125V-II features intermediate oil cooling between stages:

• Reduces compressed air temperature before entering the second stage
• Prevents excessive heat buildup
• Lowers compression resistance

👉 Result:

• Less energy required for compression
• Improved efficiency and system stability
• Enhanced component durability

🏭 Ideal Applications
