Kaishan Group · Compressor and energy equipment
Identify the company, then the machine and manufacturing location
Kaishan Group Co., Ltd. / 开山集团股份有限公司 is the Shenzhen-listed compressor and energy-equipment company with stock code 300257. Its May 2021 announcement records the change from Zhejiang Kaishan Compressor Co., Ltd. The old name is a historical company identity.
The 2026 interim filing distinguishes the listed company from its controlling shareholder, Kaishan Holding. The manufacturing introduction covers Quzhou, Shanghai Lingang, Chongqing and Shunde, alongside overseas operations. Specify the legal seller and actual works for the selected order.
This page follows the three existing compressor routes: an LG stationary air system, LGCY portable diesel equipment, or a Kaitec T-series centrifugal duty. Refrigeration, process machinery and expansion-power equipment elsewhere in the group have separate selection requirements.
Airend and package
Rotor machining and inspection connect to airend selection. Agree the driver, controls and treatment delivered around it.
Manufacturing responsibility
Group capability does not identify a particular order's factory. Name the works, test location and contracting entity in the offer.
Order evidence
Request model-specific performance, applicable destination documents and acceptance conditions. Listed-company identity is separate from equipment certification.
LG · Electrically driven stationary screw
Build the selection around the plant's air-demand profile
An LG enquiry should define the required header pressure, normal/peak delivery and how demand changes across a shift. Fixed-speed and variable-speed selections need the actual load profile and a plan for working with existing equipment.
| Power range | 4–400 kW |
|---|---|
| Airflow range | 0.5–100 m³/min |
| Pressure range | 1.5–35 bar |
These cover the wider screw portfolio; they are not one LG model's paired rating. Obtain pressure, delivery, electrical input and the flow/test reference for the offered machine.
LG series and air-system selection →Compressor → treatment → useful air
- Demand: working hours, normal/peak flow and load variation; state the receiving header pressure.
- Control: fixed-speed or variable-speed arrangement, sequencing and receiver capacity; confirm any offered ikaishan monitoring configuration and terms.
- Air quality: point-of-use moisture, oil and particulate requirements, then aftercooling, separation, drying and filtration scope.
- Site: electrical frequency/voltage, ambient conditions, ventilation or cooling, service access and installation responsibility.
LGCY · Portable diesel route
Match the tool duty, engine configuration and work-site conditions
Kaishan's portable catalog separates electric and diesel equipment. The original group image identifies an LGCY-17/17T unit. Kaishan MEA's regional brochure uses LMF LGCY for portable diesel equipment; confirm the actual brand, model and market configuration in the offer.
| Model | Listed power | Listed flow |
|---|---|---|
| LGCY P210 | 45 kW | 210 cfm |
| LGCY 22/8 | 194 kW | 825 cfm |
| LGCY 27/13 | 239 kW | 900 cfm |
The table does not provide a separate pressure column or flow-reference definition. Confirm the pressure–delivery pair; do not reconstruct guaranteed pressure from the model suffix. Diesel-driver kW is not electric package consumption.
Tool / drilling demand
Required pressure and flow together, hose and outlet arrangement, continuous/intermittent duty and aftercooling or condensate removal.
Engine / destination
Exact engine, fuel, emissions documents and site rules. Cummins/CAT options described in the regional brochure do not identify the engine in every offered unit.
Work-site / transport
Altitude, ambient range, dust, cooling-air discharge, towing/braking or skid lifting. Agree fitted spark-arrestor/shutdown options and noise test conditions.
Regional brochure configurations and maintenance/warranty conditions need confirmation against the current selected unit and operating manual; no universal availability, service interval or warranty is inferred.
Portable diesel model references and site checklist →Kaitec / KAITEC · T-series centrifugal equipment
Request a duty-specific performance and control proposal
The group's centrifugal introduction and Kaitec's company page identify Kaitec Compressors (Shanghai) as a wholly owned subsidiary. The group publishes this T-series supply envelope:
- Pressure
- 2–20 bar
- Flow
- 4–850 m³/min
- Power
- 150–6,600 kW
These independent limits do not form one operating point. Define inlet temperature/humidity, altitude, flow reference, discharge pressure and changing demand before obtaining the selected performance curve.
The group describes impeller/diffuser customisation. Kaitec's corresponding air-compressor page describes machined impellers, tilting-pad bearings, inlet-guide-vane adjustment and PLC control. Ask which arrangement the offer includes and how it maintains stable operation through the required load range.
| Industrial air | Process gas |
|---|---|
| Inlet state, altitude and the required delivery/reference; point-of-use quality and treatment. | Composition, liquid/moisture and corrosive constituents; materials, sealing and applicable safety requirements. |
| Load/control curves, surge protection, cooling-water conditions and plant sequencing. | Gas-specific performance, pressure/temperature envelope and protective/control interfaces. |
| Selected compressor input and total package utility boundary. | Defined compression train, auxiliary consumption and agreed gas test conditions. |
Make the Kaishan enquiry comparable before asking for price
- Name the route: LG stationary screw, LGCY diesel portable or Kaitec centrifugal; include the existing machine/model if replacing equipment.
- State paired duty: pressure and flow with their basis, normal/peak load, inlet/site conditions and required delivered-air or gas quality.
- Draw the boundary: driver, compressor, treatment, receiver/vessels, cooling, instruments/controls and site work.
- Agree handover: legal seller and works, drawings/service access, test conditions, destination documents, commissioning and model-specific spares/service responsibility.
Questions specific to this company and catalog
Are Zhejiang Kaishan Compressor and Kaishan Group two factories?
The listed company's May 2021 announcement records a legal-name change from Zhejiang Kaishan Compressor to Kaishan Group. Manufacturing subsidiaries and Kaishan Holding remain separate identities; name the actual order's seller and works.
Can the wider screw ranges be used as an LG model datasheet?
No. They span the wider screw portfolio. The selected LG model needs paired pressure, delivery, electrical input and stated reference/test conditions.
Does an LGCY suffix establish its guaranteed working pressure?
Use the selected model's actual datasheet and paired duty. The regional brochure table supplies cfm and power but no separate pressure column or flow-reference definition, so those missing conditions are not reconstructed from a code.
Is the centrifugal equipment supplied by the same entity as the portable machines?
The group identifies Kaitec Compressors (Shanghai) with the centrifugal line and KAITEC brand. Confirm the contracting entity, manufacturing/test location and commissioning responsibility for the specific offer.
