Dry Oil-free Screw Compressor Model Specifications:

TAM(V)37-500 Oil-free Screw Compressor PID Diagram:

Dry Oil-free Screw Compressor Advantages:

1、Excellent System Design

2、Modular Integrated Design

3、Modular System Layout

4、Air End

First and second stage material stainless steel (2Cr13), patented screw profile, grinding processing, small clearance, high efficiency, length-diameter ratio less than 1.5, strong rigidity

Air end housing material QT600-3, first and second stage housing cooling method is liquid cooling, cooling medium is lubricating oil, integrated control with system lubricating oil. Compared with using water as cooling medium, there is no risk of freezing, cracking, scaling, and condensation in the housing, ensuring stable cooling.

Rotor housing inner wall Teflon+MoS coating, 270℃ high temperature tolerance. High-precision speed increase and synchronous gears (AGM13).

5、Air End

Optimized SKF bearing structure design, high-precision cylindrical roller radial bearings, high-precision four-point ball contact thrust bearings, balanced rotor force. Compared with other ball bearings, four-point ball contact bearings have smaller axial clearance when the radial clearance is the same, higher limiting speed, suitable for 20,000-30,000 rpm requirements.

Gas seal: Suction end double balance hole stainless steel labyrinth floating ring seal, ensuring gearbox oil cannot reach the suction chamber. Exhaust end three-stage stainless steel labyrinth floating ring seal. Oil seal: Helical Teflon seal, long sealing length, small clearance, ensuring no oil leakage.

6、Drive and Intake System

Motor: IP55, IE3/IE4

Cabinet intake pre-filter design, extends intake filter life;

High-efficiency intake filter, filtration efficiency 99.9%

Integrated blowdown intake valve, pneumatic structure, no risk of oil contamination

First and second stage silencers, gas-liquid separator and pipelines are made of 304 stainless steel, corrosion-resistant, more stable and durable.

Liquid water separated by the gas-liquid separator is discharged through automatic drain without air loss.

7、Cooling System

Large specification, high-performance cooler, good cooling performance, air-cooled model temperature rise +12℃, water-cooled model temperature rise +10℃.

Condensate discharge pipelines are all made of stainless steel, more stable and durable.

Water-cooled units:

• Cooler made of stainless steel, no corrosion risk.

Air-cooled units: Variable speed, centrifugal fan

• Centrifugal fan, can be frequency conversion controlled 

• Smoother exhaust airflow 

• Low noise design

8、Oil System

ØIndependent oil pump

Pre-lubrication before start/stop and delayed oil supply after shutdown, effectively avoiding dry wear.

More beneficial for variable frequency units.

ØLubricating oil not only lubricates gears and bearings but also provides cooling for the high and low pressure casing jackets.

ØOil temperature and pressure protection (Thermostatic valve, relief valve) 

ØOil filter, ultra-long service life 8000h 

ØOil tank: Integrated design with air end, small volume;  

ØVenturi vacuum generator: Ensures slight negative pressure in the oil tank, no oil seepage in the air end;  

ØOil mist separator: 8000h ultra-long life, separation efficiency 99.9%

9、Electrical Control Cabinet

TAM series compressors default to star-delta starting method, soft starter and variable frequency drive can be optionally configured. Through the PLC control system, it can start automatically and quickly.

Standard electrical/electronic components, contained in an easy-to-operate electrical control cabinet;

PLC and HMI touch screen; 

Star-delta contactors for main motor, with auxiliary contacts, current transformers; 

Contactors, circuit breakers, current transformers for cooling fan and oil pump motors;

Power supply board; 

Control relays, control transformers and fuses;

10、Control System

ØPLC controller 

Ø10-inchHMI touch screen

•Compressor operating status

•Operating parameter setting

•Alarm/interlock shutdown

ØProgrammable input/output 

ØOptional Internet of Things module 

ØStandard SD card, can record 5 years of operating data

ØOperation and service reminders 

ØModbus communication interface and hard-wired connection reserved
