For a chemicals operation in Sasolburg, 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.
Sasolburg is approached here as a process-manufacturing environment. That means the quote should prioritise air quality, safe condensate handling, ventilation and dependable pressure control, especially where instrument air, valve actuation, transfer support and packaging equipment is part of the daily air demand. This detail is confirmed during the 18.5 kW site-planning stage for Sasolburg.
One realistic design case for this page is one chemicals line plus workshop tools that operate intermittently. 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 chemicals in Sasolburg, list the equipment behind instrument air, valve actuation, transfer support and packaging equipment 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 air quality, safe condensate handling, ventilation and dependable pressure control. A matched dryer and filter train must meet the most sensitive chemicals application without adding unnecessary pressure loss. The Sasolburg system brief links this requirement to the control and air-treatment plan for the 18.5 kW machine.
Where plastics 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. The 18.5 kW design for Sasolburg is checked against this requirement before compressor, receiver and dryer selections are finalised.
The 18.5 kW design for Sasolburg 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 chemicals process instead of treating them as optional extras. On the Sasolburg project, we confirm this specifically for the 18.5 kW package and the measured duty profile.
| Sector | Likely compressed-air uses | Specification priority |
|---|---|---|
| Chemicals | instrument air, valve actuation, transfer support and packaging equipment | air quality, safe condensate handling, ventilation and dependable pressure control |
| Plastics | material conveying, moulding auxiliaries, trimming, cooling controls and packaging | heat rejection, dry air, peak-demand storage and pressure-drop control |
| Energy | maintenance, controls, fabrication and auxiliary equipment | dust protection, heat management and predictable maintenance |
Supply the compressor for connection to a suitable existing receiver, dryer and distribution system in Sasolburg. Existing equipment should be checked for capacity and pressure loss first. For the Sasolburg application, the 18.5 kW scope states how this requirement will be handled.
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 chemicals duty. Before order placement, this point is reviewed for the specific 18.5 kW installation in Sasolburg.
Allow connection points, controls and pipe capacity for future plastics demand. Where air loss stops production, evaluate standby capacity or an emergency compressor connection. This forms part of the technical review for the 18.5 kW Sasolburg quotation rather than being treated as a standard assumption.
Motor size alone does not confirm suitability. Compare usable flow at pressure, duty cycle and air quality for each option. For the Sasolburg application, the 18.5 kW scope states how this requirement will be handled.
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. This forms part of the technical review for the 18.5 kW Sasolburg quotation rather than being treated as a standard assumption.
Base the service plan on operating hours, environment and manufacturer intervals. For a process-manufacturing environment, intake filters, cooler cleanliness, drains and ventilation deserve routine inspection in addition to oil, separator and filter changes. Before order placement, this point is reviewed for the specific 18.5 kW installation in Sasolburg.
If loss of air stops the chemicals 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. The Sasolburg system brief links this requirement to the control and air-treatment plan for the 18.5 kW machine.
Include known equipment additions and a measured margin, but avoid buying excessive unused capacity. A larger receiver, leak reduction and a VSD/base-load combination may handle growth more efficiently than simply moving to the next motor size. For Sasolburg, the 18.5 kW recommendation records this item in the equipment and installation schedule.
At a Sasolburg 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 Sasolburg.
Planned visits, reporting, open actions and critical-spares planning can be aligned to the chemicals 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 Sasolburg 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 Sasolburg.
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 Sasolburg.
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 is one of the checks used to distinguish the 18.5 kW Sasolburg package from a generic equipment-only quote.
