SOLLANT · Shandong production / Shanghai organization
A system integrator: define the factory and the supplied components
Sollant's current company page identifies Shanghai Sollant Energy Saving Technology as combining development, production, sales and service. Its history locates the screw-compressor business in Linyi, Shandong and records a Shanghai office opening in 2019.
Production role
The manufacturer describes system integration and performance control, rather than making every individual component. It states that its Shandong facility conducts incoming inspection and full-load testing before dispatch.
Order identity
Name the contracting company, assembly site and inspection location on the offer. The published component-supplier examples include SKF and Inovance; request the actual bill of materials and test record for the selected machine.
The three established equipment pages below address different decisions: a small stationary package, a pressure-specific two-stage PM variable-speed selection, and an engine-powered portable compressor.
Workshop air · 11 kW route
Agree drive and delivered air before approving the small package
- Published motor power
- 11 kW
- Configurable pressure
- 7–12 bar · selected version to be agreed
- Physical reference
- 400 kg · 1,150 × 820 × 1,130 mm
The page says a frequency converter can be added. Confirm fixed-speed or variable-speed drive. Its motor-protection wording is IP23/55; obtain the specification of the actual supplied motor.
The page does not give a pressure-matched capacity row. Send required flow at the chosen pressure, load variation, supply and installation conditions, then request the corresponding performance sheet.
11 kW configuration and scope →SLTT · Two-stage oil-injected PM variable speed
Keep working pressure and capacity on the same line
The two-stage description identifies oil injection for cooling between compression stages. This remains an oil-injected route. Select drying and filtration for the required downstream quality; two stages and PM drive do not establish oil-free air.
SLTT-22V is a 22 kW table entry with DN40, 732 kg and 1,610 × 1,050 × 1,380 mm. Its capacity range changes with working pressure. Request the actual performance reference conditions, complete-package input and control settings.
| Working pressure | Published capacity range |
|---|---|
| 8 bar | 2.00–4.55 m³/min |
| 10 bar | 1.72–3.83 m³/min |
| 13 bar | 1.36–3.04 m³/min |
Use the pressure-specific minimum and maximum when describing demand. Ask how the offered controller handles demand below the range and sequencing with existing machines. Compare energy at the same delivered-air duty, rather than using a generic savings percentage.
SLTT operating points and installation requirements →SLTDP · Air where electrical supply is unavailable
Choose the engine column as carefully as the air duty
SLTDP-5/7 · single-stage example
- Air duty
- 5 m³/min at 7 bar
- Engine
- Quanchai QC490GP · 37 kW rated
- Engine speed
- 2,200 rpm full load / 1,500 rpm minimum load
- Fuel & operational weight
- 70 L tank · 960 kg
- Transport reference
- 3,193 × 1,446 × 1,428 mm · two tyres
- Listed outlets
- G1, G1
The next size has a different engine
SLTDP-7.5/8 lists 7.5 m³/min at 8 bar and a Cummins QSB3.9-C80 · 60 kW engine, with a 140 L tank, 1,500 kg operational weight and 3,900 × 1,600 × 1,930 mm.
A family-page mention of Cummins or Yanmar does not change the Quanchai engine specified in the 5/7 column. Obtain the offered engine revision and destination emissions documents.
Resolve environment and movement
The table gives 50°C maximum ambient, while the narrative describes operation up to 45°C. Obtain written limits for the offered configuration and the site's altitude and ambient conditions.
Agree coupling, brakes, tyres, handling and any required road-use documents. A wheeled photograph does not establish road registration. Tank litres do not establish runtime; ask for consumption at the actual load.
Acceptance · Turn published processes into order records
Ask for the records that make the offer comparable
Pressure, flow and complete-package input
The company page lists pressure, exhaust-flow and total-power measurements. Request serial/model-specific results, reference conditions, input boundary and applicable instruments/calibration for the agreed duty.
Assembly and electrical configuration
Its stated incoming inspection and full-load testing describe the production approach. Attach the actual component list, supply or engine details, control version, approved layout and safety/inspection requirements.
Air treatment and delivery scope
The company also lists dryer dew-point testing. If treatment is supplied, agree dew point at site conditions, capacity, pressure loss and drainage. Receiver, drying and filtration must be itemized rather than assumed included.
Send the right brief for the route
Stationary: pressure and demand by shift, electrical supply, ambient, ventilation, floor plan, air-quality limits and existing storage/control arrangement.
Portable: tools used simultaneously, pressure at the tools, line length/losses, working cycle, terrain/movement, ambient/altitude and engine/destination requirements.
For either route, agree the seller and assembly/inspection site, offered version, manuals, consumables, commissioning and the actual destination service arrangement.
Send a Sollant duty and configuration brief →Sollant purchase questions
Does Sollant make every component itself?
Its current production description emphasizes system integration and performance control, with suppliers for critical components and incoming inspection in Shandong. Confirm the ordered bill of materials and request the unit-specific test record.
Can SLTT-22V deliver 4.55 m³/min at 13 bar?
That maximum belongs to the 8 bar row. At 13 bar the table lists 1.36–3.04 m³/min. Request the selected version and performance conditions.
Is the 11 kW package always fixed speed and IP55?
The product page offers a frequency converter and lists IP23/55 without specifying one universal motor. Agree the actual drive and motor protection. The gallery image is marked SLT11V.
Does the SLTDP-5/7 come with the Cummins engine in the next column?
The selected column lists Quanchai QC490GP. SLTDP-7.5/8 lists Cummins QSB3.9-C80. Confirm the offered engine version and destination compliance for the actual model.
Can the diesel unit operate at 50°C?
The specification graphic and narrative have different upper limits. Put the actual site ambient and altitude on the enquiry and obtain the offered configuration's written limit.
