HANDE · Guangdong · Boluo / Huizhou
Start with the compression architecture, then define the complete station
Guangdong Hande Precision Machinery is based in Yuanzhou, Boluo. Its official history dates the company's formal establishment to 2016, separately from the founder's earlier compressor repair and sales experience.
The stated operating model combines development, production and sales, centered on two-stage and PM variable-speed screw equipment. Its catalog also separates oil-free, integrated packages, vacuum, piston and air-treatment divisions. Purification, filtration and separation are system offerings; their inclusion belongs on the actual equipment list.
Which decision are you making?
- Factory air: choose the HD-EPM2T working-pressure version and the corresponding delivered air, package dimensions and controls.
- Process air: distinguish dry screw, scroll and water-lubricated screw, then define quality limits and treatment at the users.
- Piston or higher-pressure duty: compare actual air delivery, receiver and cooling requirements, without substituting piston displacement.
HD-EPM2T · Two-stage PM variable-speed screw
The pressure version changes the technical comparison
HD-EPM2T37 · 37 kW example
The table lists air cooling, −5 to 45°C ambient, 950 kg and 1,950 × 1,100 × 1,390 mm. Its outlet changes from DN65 at 0.5 MPa to Rp1½ at the three higher pressures.
| Pressure | Air quantity |
|---|---|
| 0.5 MPa · 5 bar | 8.2 m³/min |
| 0.8 MPa · 8 bar | 6.8 m³/min |
| 1.0 MPa · 10 bar | 6.1 m³/min |
| 1.25 MPa · 12.5 bar | 5.2 m³/min |
At 75 kW, do not reuse the 5 bar package size for the 8 bar offer
- HD-EPM2T75 · 0.5 MPa
- 18.8 m³/min
- 2,630 kg · DN100
- 2,990 × 1,700 × 1,963 mm
- HD-EPM2T75 · 0.8 MPa
- 15.6 m³/min
- 2,110 kg · DN65
- 2,590 × 1,500 × 1,640 mm
The 1.0 and 1.25 MPa rows list 13.0 and 11.0 m³/min. Keep the full model and pressure on the offer and drawing; obtain performance reference conditions and complete-package input before comparing energy.
Plan the compressor room around access
The manufacturer describes independent air-intake paths for the filter, motor and electrical cabinet, segmented coolers and a lifting/rotating oil-separator vessel cover. Request ventilation routing, cooler removal/cleaning clearances and overhead space for the cover on the actual arrangement.
Process air · Architecture and utilities
“Oil-free” covers three different equipment routes
HD-DSPM · Dry screw
The source describes a compression chamber without oil and non-contact rotors with synchronizing gears. Obtain the actual service manual; this does not mean every part of the machine is maintenance-free.
HD-SRL · Scroll
HD-SRL4 lists 3.7 kW and 0.36 m³/min at 0.8 MPa, with air cooling, Rp½, 150 kg and 650 × 700 × 1,015 mm. It is a separate architecture from the large dry screw.
HD-ZW · Water-lubricated screw
The catalog identifies this as another route. Define the actual selected model, water-system conditions and maintenance requirements rather than borrowing a dry-screw row.
| Model / duty | Utilities | Physical package |
|---|---|---|
| HD-DSPM90 90 kW · 14.9 m³/min | Air-cooled · 0–40°C ambient DN65 | 2,850 kg 3,150 × 1,750 × 1,800 mm |
| HD-DSPM200 200 kW · 31.3 m³/min | Water-cooled · 0–40°C ambient DN100 | 5,200 kg 3,800 × 2,280 × 2,200 mm |
Specify oil, particle and moisture limits at the process users. Request the selected equipment's applicable quality/test documents and treatment capacity, pressure loss and drainage. A division label does not establish a universal certificate, and an oil-free compression route still needs a defined air-treatment system.

Piston displacement is not the delivered-air quantity
HDW6708 · 0.8 MPa example
Listed air quantity0.67 m³/min
Separate piston displacement1,068 L/min
The table gives 5.5 kW, a 150 L receiver and 198 kg. Use the discharge quantity when defining demand; the displacement column is a different measure.
The HDW external dimensions have an apparent unit/scale inconsistency. Obtain the final approved drawing before arranging transport and installation; do not infer a size from an assumed conversion.
Higher-pressure piston example
HDW60025 lists 0.60 m³/min at 2.5 MPa, 7.5 kW, displacement 830 L/min, a 250 L receiver and 362 kg.
Agree the actual operating cycle, pressure-rated receiver and piping, safety devices and destination inspection requirements.
A separate screw/piston serial system
HD-SPC67F-40 lists 6.0 m³/min at 4.0 MPa and 67 kW. Its water-cooled table entry includes 20 t/h circulating-water flow, Rc1½ water connection, DN40 air outlet, 3,200 kg and 2,840 × 1,500 × 1,480 mm; ambient 0–40°C.
Specify the inlet and water-system conditions for the offered arrangement. The wheeled HDW photograph does not describe this larger system.
Factory evidence · Performance acceptance
Connect the testing facility to the ordered machine's record
The published history describes an energy-efficiency testing laboratory established at the factory in 2019. Request the ordered model's pressure, air-delivery and package-input results, reference conditions and relevant calibration.
A Guangdong government 2022 high-tech-enterprise list names this exact company in Huizhou. This is historical company recognition; current model certification and performance acceptance require their own applicable documents.
Define destination service and controls
The service page describes consultation, system layout/selection, installation/commissioning, operator-maintenance training, running-service records, repairs and upgrades. Agree the responsible provider and coverage at the actual destination.
Its library contains multiple controller/inverter manuals. Identify the installed hardware and document revision; the whole library is not one machine's operating manual.
Attach a model and station brief
- Required pressure and normal/peak/minimum demand by shift.
- Full model/pressure version, supply, ambient and cooling utilities.
- Room access, ventilation, maintenance clearances and handling plan.
- User air-quality limits, treatment/storage/drainage list and existing controls.
- Approved drawings, test/inspection documents, manuals, consumables and commissioning responsibilities.
Hande selection questions
Can I compare every HD-EPM2T75 by its largest flow figure?
The 18.8 m³/min entry belongs to 0.5 MPa. At 0.8 MPa the table lists 15.6 m³/min, with different package size, mass and outlet. Keep pressure and version on the comparison.
Does oil-free mean the complete machine needs no maintenance?
The dry-screw description concerns the compression chamber. Obtain the service manual and actual consumables for the selected architecture and model, along with applicable process-air documents.
Is HDW6708's delivered air 1,068 L/min?
That is the piston-displacement column. Its listed discharge quantity is 0.67 m³/min at 0.8 MPa. The table separates these measures.
Can HD-DSPM200 replace an air-cooled package without a utility change?
The selected entry is water-cooled. Obtain cooling-water requirements, connections and arrangement for the offered model before comparing it with air-cooled HD-DSPM90.
Do the service-page manuals all apply to my controller?
Identify the actual supplied controller/inverter and document revision. Agree commissioning, training and destination support with the selected hardware and offer.
