Choose a compressor, then define the whole station
Sazhen Compressor (Shanghai) Co., Ltd. supplies SEIZE AIR compressors and station solutions. Its official Chinese company presentation dates the business to 2009 and identifies a manufacturing location in Shanghai's Jinshan Industrial Zone.
The catalog spans oil-injected screw, dry oil-free, water-lubricated, centrifugal and mobile equipment, with downstream treatment and station controls. The international presentation uses Seize International Trading (Shanghai) Co., Ltd.; agree the actual seller and manufacturer on the commercial and inspection documents.
Manufacturing questions with a purpose
SEIZE describes rotor machining, dimensional inspection, balancing and performance testing. Request the actual test conditions, production/inspection location and model-specific documents for the proposed package.
The national standards platform names Sazhen as a drafting organization for a green-product assessment standard plan. That role corroborates identity; it is not certification of every compressor.
Single-stage oil-injected PM variable-speed screw
Match controllable delivery to the shift demand
The current Chinese page describes direct drive, variable-frequency temperature control, and air- or water-cooled versions. Its published family pressure range is 0.75–1.23 MPa.
For a useful selection sheet
- Minimum, normal and peak consumption, operating hours and required user pressure.
- Flow reference conditions, complete-package input power and exact electrical supply.
- Control range and operation below that range; receiver and existing compressor sequencing.
- Cooling, treatment, condensate and routine-service boundary.
A PM motor and variable-speed drive describe the architecture. They do not establish a fixed energy saving for every demand profile.
Single-stage PM selection details →Two-stage oil-injected PM variable-speed screw
Compare the duty point and station behavior together
The Chinese two-stage family page lists a 0.45–1.25 MPa pressure range and air- or water-cooled arrangements. Family coverage does not mean one pictured model provides the same flow across that range.
Align inlet/ambient conditions, working pressure, delivered-air reference conditions and package input power. Check minimum-load behavior, sequencing and standby, alongside the full-load operating point.
Two-stage package details →Dry oil-free screw · Two-stage route
Set the quality requirement at the point of use
The Chinese product page describes double labyrinth sealing with an atmospheric opening between seals, variable-frequency control and air- or water-cooled versions. It lists 380 V / 50 Hz as a supply configuration.
Request the exact SWT selection: pressure, flow, reference conditions, package input power, cooling and electrical version. Keep data from different stage counts and cooling arrangements separate.
Dry oil-free equipment details →Define the required result
Moisture, particles and total oil at the actual air user; sample location, treatment and acceptance method. Dry compression alone does not define the complete installed air quality.
Check the evidence scope
For a required certificate, obtain model coverage, operating conditions, validity and test scope for the offered machine. Tie the document to the selected configuration.
Agree the service boundary
Cooling, intake filtration, condensate management, gearbox/bearing maintenance, access and shutdown procedures, with routine parts and commissioning responsibility.
A testable energy comparison
Use the same pressure, production pattern and measurement boundary
Record the baseline
Measured station electricity, delivered air, user pressure, production pattern and operating hours. Identify which compressors and auxiliary loads are included.
Align the proposed duty
Model-specific performance, controllable range, sequencing, cooling, treatment and standby. Keep dryer purge, pressure losses and options visible.
Agree the comparison period
Post-commissioning measurements at the same system boundary and comparable load. Record changed production or pressure settings before interpreting the result.
SEIZE emphasizes coordinated controls, treatment and monitoring. A compressor-only motor rating does not measure the electricity used by the complete air station.
Prepare a comparable SEIZE offer
Attach the load profile and define what is included
- Equipment route
- Single-stage oil-injected, two-stage oil-injected or dry oil-free; exact selected model and version.
- Performance & site
- Pressure/flow basis, ambient/inlet conditions, demand pattern, electrical supply, cooling, layout and service space.
- Station scope
- Receiver, dryers, filters, condensate, controls, communications, standby and installation/commissioning boundaries.
- Documents & acceptance
- Actual contracting/manufacturing entities, drawings, model-specific evidence, performance test, inspection location and routine spares.
SEIZE station-selection questions
Does PM VSD guarantee a fixed saving?
Actual results depend on demand, pressure, control and the compared system boundary. Obtain model-specific performance and agree baseline and post-commissioning measurements.
Can the automotive example size my factory?
It is a manufacturer-reported configuration of three160kW SVC-160A-II units at0.7–0.8MPa. Your required delivery, demand pattern, treatment and standby need their own selection.
Does the dry oil-free image prove my complete air quality?
Agree point-of-use requirements, treatment, sampling and scoped evidence for the offered model and operating conditions.
Which company name belongs on the order?
The Chinese manufacturer and international trading presentation use different legal names. Confirm the actual seller, manufacturer and inspection location on the commercial and technical documents.
