For a sishen mine operation in Kathu, an 18.5 kW screw compressor is best treated as a complete air-system decision rather than a stand-alone machine purchase.
Typical planning role: a multi-user production line or process-support duty.
This page focuses on the needs of a mining-linked production and maintenance environment in Kathu, with the system configured around sishen mine, iron ore and the site’s own uptime target. For the 18.5 kW Kathu proposal, this point is verified against the submitted site data before the final scope is issued.
One realistic design case for this page is a growing plant where sishen mine demand is steady but future iron ore equipment is planned. The 18.5 kW unit supplies about 3.0 m³/min at a typical 7 bar reference point, but the decision must be checked at the site’s actual pressure and simultaneous demand.
For sishen mine in Kathu, list the equipment behind pneumatic equipment, cleaning, tooling and production support and separate steady consumers from short peaks. This determines whether 18.5 kW is a base-load match or only one part of the final system.
The package should address measured demand, moisture control, service access and pressure stability. A matched dryer and filter train must meet the most sensitive sishen mine application without adding unnecessary pressure loss. For the 18.5 kW Kathu proposal, this point is verified against the submitted site data before the final scope is issued.
Where iron ore demand changes through the shift, VSD may reduce unloaded operation. Where demand is stable, fixed-speed can remain the better-value option. The choice should follow a demand profile, not a general rule. On the Kathu project, we confirm this specifically for the 18.5 kW package and the measured duty profile.
The 18.5 kW design for Kathu uses that local operating context to set storage, filtration, ventilation and maintenance requirements.
For this 18.5 kW page, the strongest proposal is one that links receiver storage, room ventilation, filtration and maintenance access to the sishen mine process instead of treating them as optional extras.
| Sector | Likely compressed-air uses | Specification priority |
|---|---|---|
| Sishen Mine | pneumatic equipment, cleaning, tooling and production support | measured demand, moisture control, service access and pressure stability |
| Iron Ore | pneumatic equipment, cleaning, tooling and production support | measured demand, moisture control, service access and pressure stability |
| Logistics | vehicle workshops, loading equipment, maintenance bays and packaging support | fast recovery, practical pipe routing and dependable service access |
Supply the compressor for connection to a suitable existing receiver, dryer and distribution system in Kathu. Existing equipment should be checked for capacity and pressure loss first. For the 18.5 kW Kathu proposal, this point is verified against the submitted site data before the final scope is issued.
Combine the 18.5 kW machine with a reviewed 500–1 000 L receiver range, refrigeration dryer, pre-filter, coalescing filter and automatic drains for the sishen mine duty.
Allow connection points, controls and pipe capacity for future iron ore demand. Where air loss stops production, evaluate standby capacity or an emergency compressor connection. For the Kathu application, the 18.5 kW scope states how this requirement will be handled.
Motor size alone does not confirm suitability. Compare usable flow at pressure, duty cycle and air quality for each option. For the Kathu application, the 18.5 kW scope states how this requirement will be handled.
Specify the minimum pressure required at the furthest user, then calculate losses through pipework, filters and the dryer. Raising the compressor set point to compensate for a restrictive network wastes energy, so the distribution system should be checked first. Before order placement, this point is reviewed for the specific 18.5 kW installation in Kathu.
The scope can include delivery, off-loading, positioning, receiver and dryer connections, airline tie-in, electrical coordination, commissioning and operator handover. The final quotation separates included work from any site preparation required before arrival. For Kathu, the 18.5 kW recommendation records this item in the equipment and installation schedule.
Base the service plan on operating hours, environment and manufacturer intervals. For a mining-linked production and maintenance environment, intake filters, cooler cleanliness, drains and ventilation deserve routine inspection in addition to oil, separator and filter changes. The Kathu system brief links this requirement to the control and air-treatment plan for the 18.5 kW machine.
If loss of air stops the sishen mine process, compare the cost of downtime with a duty/standby arrangement or an emergency connection point. Redundancy can sometimes be phased in, but the pipework and controls should allow for it from the start.
At a Kathu site, reliability depends on the compressor, cooling, storage, treatment and distribution working together. For an 18.5 kW unit, coordinate filters, oil, separator, drive, cooling, valves and electrical condition.
Oil, filters, separator, drive, cooling, drains and controls are scoped from the exact machine.
Alarms, pressure, temperature, current and behaviour help separate component, demand, ventilation and pipework faults in Kathu.
Planned visits, reporting, open actions and critical-spares planning can be aligned to the sishen mine duty.
Air treatment, drains, storage, leaks and point-of-use pressure can be included where they affect the problem.
Yes. Send the model, serial, hours, service history and exact Kathu site details so travel, parts and shutdown needs can be quoted.
Send the alarm, operating symptom, available pressure and temperature, nameplate and controller photos, site contact, access details and production impact in Kathu.
Coverage note: service availability, travel and response are confirmed for the exact site. This page describes coverage and does not represent a separate staffed branch in Kathu.
Send the air users, pressure, hours, electrical supply, existing equipment and delivery position. We will respond with a defined compressor, receiver, dryer, filtration and installation scope. This detail is confirmed during the 18.5 kW site-planning stage for Kathu.
