B&D equipment and digital services have different delivery boundaries
The Chinese official site identifies Guangdong Baode Technology; the English site uses B&D Technology and a B&D Holdings Group copyright identity. Put the actual manufacturing and contracting companies on the offer.
The business separates energy equipment, industrial digital services and broader energy planning/design/operation. Its compressor portfolio spans oil-injected screw, low-pressure, laser cutting, scroll, water-lubricated screw, dry screw and centrifugal equipment.
CRM and energy-management software are service categories. Identify actual hardware, sensors, connectivity and permissions included with the selected compressor.
Tianqin · BD-LS oil-injected PM variable-speed
Match the discharge-volume range to the pressure version
The Tianqin range uses a vertical oil-cooled PM assembly and air cooling. The page has two table headings in its MPa pressure context: 0.7 / 0.6–0.8 and 1 / 0.8–1. Carry the actual offered pressure version with the flow range.
| Model / power | 0.7 / 0.6–0.8 heading | 1 / 0.8–1 heading | Dimensions / mass |
|---|---|---|---|
| BD-LS37 37 kW | 2.48–6.2 m³/min | 2.2–5.5 m³/min | 1,576 × 980 × 1,620 mm / 615 kg |
| BD-LS75 75 kW | 4.72–11.8 m³/min | 4.2–10.7 m³/min | 1,865 × 1,250 × 1,900 mm / 1,250 kg |
The overview's 7.3–10.7 volume range does not represent every detailed model row. The source names alternative supplies and -5 to +40°C ambient; confirm selected voltage/phase/frequency, controller, input and flow basis.
Choose against the daily demand profile. A variable-speed range does not establish a universal energy-saving percentage.

The pressure variant and treatment belong on the same quote
The manufacturer describes PM variable-speed screw compression, a refrigerated dryer and five-stage precision filtration, with a 2–8°C pressure-dew-point description. Confirm the actual rating conditions, treatment sequence and pressure loss at the cutting nozzle.
1.5 MPa working pressure
BD-PM15TK: 15 kW; range 1.2–1.5 MPa; 0.56–1.4 m³/min.
BD-PM22TK: 22 kW; range 1.2–1.5 MPa; 0.88–2.2 m³/min.
Different physical packages: 1,600 × 750 × 1,680 mm / 438.5 kg and 1,722 × 800 × 1,880 mm / 564 kg respectively.
Higher-pressure PM22TK rows
2.5 MPa version: range 2.0–2.5 MPa; 0.6–1.2 m³/min; 22 kW.
3 MPa version: range 2.5–3 MPa; 0.6–1.03 m³/min; 22 kW.
Both source rows list 1,716 × 830 × 1,862 mm and 755 kg. Identify the actual pressure variant.

The integrated PM table's heading and its pressure-start/stop control row need confirmation for the offered controller. The -15°C outlet-dew-point entry needs test/ambient and package conditions.
Request the commissioning and operating records with the machine
The manufacturer's commissioning-service document covers installation planning, ventilation, supply and pipeline/treatment arrangement. It describes model/date/environment records, a customer-confirmed start-up report, inspection records and energy comparisons.
Selected unit and site
Full model/pressure version, manufacturing/serial details, demand profile, ambient/altitude, supply and cooling. For GS, identify process-water and cooling requirements separately.
Included package and access
Dryer/filter/receiver, drains, discharge connection, distribution losses, maintenance access, controls, sensors and cloud connectivity/permissions.
Acceptance and service
Flow/input reference conditions, quality measurement, qualified commissioning, current manuals, start-up confirmation, original consumables/parts and destination support responsibilities.
Use the selected model's current manual and qualified commissioning. A generic booklet is not a configuration sheet for every mechanism in the group portfolio.
Prepare an enquiry for one defined B&D duty
Choose Tianqin industrial air, the exact TK pressure variant or the GS/WS mechanism. Attach user pressure, demand and quality, then request the complete scope and acceptance records.
Prepare a B&D compressor enquiry →B&D selection questions
Does one Tianqin volume range apply to all pressure versions?
No. The detailed BD-LS37 entries differ between the two pressure-table headings: 2.48–6.2 and 2.2–5.5 m³/min. Confirm the actual selected version and rating basis.
Are the 2.5 and 3 MPa PM22TK rows interchangeable?
No. They have different pressure and delivery ranges. Match the offered variant and treatment rating to the nozzle demand and quality requirement.
Are GS volumes quoted for every pressure in the range?
The original table note says the volumes refer to the 0.8 MPa design condition. Obtain a separate pressure-qualified duty sheet for another operating point.
Does standards drafting establish an oil-free certificate?
No. The reviewed participation concerns a single-screw standard. Request applicable current model-specific quality evidence and define delivered oil/moisture/particle conditions separately.
