Product Description

To lower your overall production overhead, ordering a China Energy-Saving Oil-Injected Screw Compressor from DECHUAN is a proven solution. Built with an optimized vertical oil separator vessel, this unit reduces oil residue while lowering your specific energy requirement (SER) by 3.3% compared to older belt-driven systems.

Maximizing Every Kilowatt: Stopping Power Losses in Industrial Air Systems

In continuous manufacturing facilities, air compressors are often the largest single consumers of electricity on the factory floor. Traditional, outdated screw air compressors suffer from high energy losses due to inefficient internal piping, friction-heavy belt drives, and poorly designed separation vessels that vent large amounts of pressurized air into the room every time the machine unloads during low-demand cycles.

The compressor directly addresses these expensive energy losses. By optimizing internal fluid dynamics and using a direct-coupled gear drive system, DECHUAN reduces mechanical friction losses to nearly zero. Additionally, the system features a newly upgraded vertical oil-gas separator vessel that uses a low-resistance path to minimize pressure drops inside the machine, keeping your specific energy requirement (SER) exceptionally low across your entire production week.

Energy-Saving Oil-Injected Screw Compressor

How Much Carbon and Capital Is Your Current Compressed Air Infrastructure Wasting?

Industrial facilities face strict carbon reduction mandates and rising electrical energy costs. Since air compressors are often the largest single source of power consumption on the factory floor, maximizing efficiency is critical. The Energy-Saving Oil-Injected Screw Compressor is designed to address this challenge by combining optimized rotor designs with high-performance cooling systems.

The asymmetric male and female screw profiles provide an optimal compression ratio with minimal air slippage. Combined with an oversized vertical oil-gas separator tank, this design reduces internal pressure drops, allowing the Energy-Saving Compressor to deliver more free air per kilowatt of power input.

Energy-Saving Oil-Injected Screw Compressor

Multi-Industry Application Spotlight & Reclaimed Thermal Solutions

Our Energy-Saving Oil-Injected Screw Compressor provides reliable, high-volume air output while supporting facility heating goals through optional waste heat recovery integration:

Coal Industry Bathhouse Applications: By connecting a secondary plate heat exchanger to the compressor's oil circuit, a coal facility can reclaim high-temperature thermal energy to heat wash water for staff facilities, saving substantial amounts of boiler steam.

Pharmaceutical Water Preheating: Reclaims heat from centrifugal and screw air loops to preheat boiler feedwater and reverse osmosis filtration lines, converting mechanical waste heat into direct utility savings.

Automotive Paint Shop Air Preheating: Uses recovered thermal energy to warm intake air for downstream spray lines during winter months, reducing the facility's gas heating requirements.

Case Study: Reclaiming Thermal Energy in the Packaging Industry

An international packaging manufacturer in Shanghai retrofitted two 35kW compressors with DECHUAN Energy-Saving Oil-Injected Screw Compressor units equipped with modular heat recovery systems.

The heat recovery skid was linked to the facility's internal water circulation loop, producing a continuous supply of hot water above 70°C. This hot water met the factory's process water requirements completely, eliminating the need for their old electric immersion heaters and reducing total plant energy consumption by an additional 18%.

Technical Procurement FAQ

Q: What design feature allows the Energy-Saving Compressor to achieve higher efficiency during loading cycles?

A: The compressor uses a redesigned vertical oil-gas separation system. This optimized layout minimizes internal pressure drops during the compression cycle, allowing the machine to discharge air with less resistance and reducing overall specific energy requirements (SER) by an average of 3.3%.

Q: Can this energy-saving air compressor operate reliably in high ambient temperatures?

A: Yes. The Energy-Saving Oil-Injected Screw Compressor features an independent cooling fan and high-efficiency aluminum block radiator matrix, allowing it to sustain continuous operation in ambient temperatures up to 46°C without risk of thermal shutdown.

Q: What is the typical return on investment (ROI) timeframe for this high-efficiency compressor upgrade?

A: For facilities running continuous two- or three-shift operations, the energy savings and reduced maintenance costs typically offset the initial capital expenditure within 12 to 18 months.
