Before pricing a 55 kW machine for Secunda, the system should be mapped from the furthest point of use back to the compressor room to expose pressure loss and storage needs.
Typical planning role: a high-demand central compressed-air network.
For the type of coal-to-liquid and energy work associated with this Secunda page, the design emphasis is measured demand, moisture control, service access and pressure stability. Those items have a direct effect on reliability and operating cost. For Secunda, the 55 kW recommendation records this item in the equipment and installation schedule.
One realistic design case for this page is one coal-to-liquid line plus workshop tools that operate intermittently. The 55 kW unit supplies about 9.5 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 coal-to-liquid in Secunda, list the equipment behind pneumatic equipment, cleaning, tooling and production support and separate steady consumers from short peaks. This determines whether 55 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 coal-to-liquid application without adding unnecessary pressure loss. The final 55 kW proposal for Secunda will show whether this is included, optional or dependent on site preparation.
Where energy 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. For the Secunda application, the 55 kW scope states how this requirement will be handled.
For the 55 kW installation in Secunda, the next step is to turn that context into measurable flow, pressure and air-quality criteria.
For this 55 kW page, the strongest proposal is one that links receiver storage, room ventilation, filtration and maintenance access to the coal-to-liquid process instead of treating them as optional extras.
| Sector | Likely compressed-air uses | Specification priority |
|---|---|---|
| Coal-To-Liquid | pneumatic equipment, cleaning, tooling and production support | measured demand, moisture control, service access and pressure stability |
| Energy | maintenance, controls, fabrication and auxiliary equipment | dust protection, heat management and predictable maintenance |
| Coal-To-Liquid | pneumatic equipment, cleaning, tooling and production support | measured demand, moisture control, service access and pressure stability |
Supply the compressor for connection to a suitable existing receiver, dryer and distribution system in Secunda. Existing equipment should be checked for capacity and pressure loss first. In the Secunda quotation, this is matched to the actual operating pattern of the proposed 55 kW system.
Combine the 55 kW machine with a reviewed 2 000–3 000 L receiver range, refrigeration dryer, pre-filter, coalescing filter and automatic drains for the coal-to-liquid duty.
Allow connection points, controls and pipe capacity for future energy demand. Where air loss stops production, evaluate standby capacity or an emergency compressor connection. Before order placement, this point is reviewed for the specific 55 kW installation in Secunda.
Motor size alone does not confirm suitability. Compare usable flow at pressure, duty cycle and air quality for each option. For the 55 kW Secunda proposal, this point is verified against the submitted site data before the final scope is issued.
2 000–3 000 L is a practical starting range, but the receiver must be checked against demand peaks, control method and available space. Short events linked to pneumatic equipment, cleaning, tooling and production support may justify more storage instead of oversizing the compressor. The Secunda system brief links this requirement to the control and air-treatment plan for the 55 kW machine.
Most production systems benefit from a matched refrigeration dryer and filtration. The required dew point and filter grade depend on the coal-to-liquid process; sensitive instruments or product-contact risks may require a different air-quality design. For Secunda, the 55 kW recommendation records this item in the equipment and installation schedule.
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. The final 55 kW proposal for Secunda will show whether this is included, optional or dependent on site preparation.
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. Before order placement, this point is reviewed for the specific 55 kW installation in Secunda.
For equipment in Secunda, first determine whether the need is routine maintenance, diagnosis, repair or overhaul. For a 55 kW unit, coordinate production shutdowns, service quantities, cooler cleaning and major-component risk.
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 Secunda.
Planned visits, reporting, open actions and critical-spares planning can be aligned to the coal-to-liquid 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 Secunda 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 Secunda.
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 Secunda.
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. The 55 kW design for Secunda is checked against this requirement before compressor, receiver and dryer selections are finalised.
