LPG for Central Kitchens in Singapore: Supply Planning, Storage and Delivery

A central kitchen has very different LPG requirements from a small restaurant. When dozens or even hundreds of meals are prepared from one location, a reliable LPG supply becomes essential for keeping production moving without unnecessary interruptions.

For businesses operating a Commercial Kitchen, central kitchen, catering facility, cloud kitchen, or food production operation in Singapore, proper LPG planning should cover supply capacity, cylinder storage, manifold design, delivery schedules, safety, and future growth.

What Is a Central Kitchen?

A central kitchen is a production facility where food is prepared, cooked, portioned, or processed before being distributed to restaurants, outlets, catering locations, or customers.

Unlike a standard restaurant kitchen, a central kitchen may operate for longer hours and use several gas-powered appliances at the same time.

These can include:

• Commercial wok burners

• Gas ranges

• Cooking kettles

• Ovens

• Steamers

• Fryers

• Grills

• Other high-output cooking equipment

Because several appliances may operate simultaneously, LPG supply planning becomes an important part of the facility's daily operations.

Why LPG Supply Planning Matters for Central Kitchens

A central kitchen cannot afford frequent gas interruptions during production.

A shortage of LPG can delay food preparation, affect delivery schedules, increase labour downtime, and create problems across multiple outlets that depend on the central facility.

Good LPG supply planning starts by understanding the facility's actual consumption.

Consider:

• Number of gas appliances

• LPG consumption of each appliance

• Daily operating hours

• Peak production periods

• Number of production shifts

• Expected monthly LPG usage

• Future increases in production

Do not size an LPG system only around average daily consumption. Peak demand should also be considered.

For a useful starting point, you can review our guide on How to Calculate LPG Consumption for a Commercial Kitchen.

LPG Manifold Systems for Central Kitchens

Central kitchens with higher LPG demand commonly require a structured cylinder and manifold arrangement rather than relying on individual cylinder connections.

A typical system can be arranged as:

LPG cylinders → Manifold → Changeover system → Regulator → LPG piping → Appliances

A manifold allows multiple cylinders to work together as part of a centralised supply system. A suitably designed changeover system can also move the gas supply to a reserve cylinder bank when the active bank becomes depleted.

This can be particularly useful where cooking continues for long periods and an interruption would affect production.

You can learn more about this system in How Automatic LPG Changeover Prevents Commercial Kitchen Downtime.

How to Choose the Right LPG Cylinder Capacity

Cylinder capacity should be based on actual consumption rather than simply choosing the largest available option.

A central kitchen using a few appliances may have very different requirements from a facility producing thousands of meals each day.

When determining cylinder capacity, consider:

Daily LPG Consumption

Estimate how much LPG the kitchen uses during normal production.

Peak Consumption

Identify periods when multiple appliances operate simultaneously.

Operating Hours

A facility operating 10–12 hours a day may need a different supply arrangement from one operating around the clock.

Delivery Frequency

Higher consumption may require more frequent replenishment unless adequate reserve capacity is available.

Future Expansion

If production is expected to increase, discuss future capacity during the initial LPG system planning.

The objective is to maintain sufficient LPG availability without creating an unnecessarily large installation.

LPG Cylinder Storage for Central Kitchens in Singapore

Storage is one of the most important parts of LPG planning.

Under Singapore's current SCDF Fire Code, LPG cylinder installations in commercial and industrial buildings are generally required to be located outdoors and at ground level, subject to provisions that apply to specific indoor installations. The Code also contains requirements covering cylinder quantities, separation distances, manifold arrangements, housing, ventilation, and fire-safety provisions.

The cylinder area should therefore be considered before the central kitchen layout is finalised.

Important considerations include:

• Adequate ventilation

• Access for cylinder replacement

• Separation from exits and building openings

• Distance from drains and pits

• Separation from mechanical air intakes

• Protection from accidental impact

• Emergency access

• Appropriate cylinder housing or fencing

Our detailed guide explains these requirements in LPG Cylinder Storage Requirements for Restaurants in Singapore.

Although that article focuses on restaurants, many of the storage considerations are relevant when planning LPG installations for commercial food-production facilities.

How LPG Delivery Planning Works for Central Kitchens

Delivery planning becomes more important as LPG consumption increases.

A restaurant may be able to manage its gas usage with relatively small and predictable deliveries. A central kitchen may need a more structured delivery schedule because running low on LPG can affect production across several locations.

Track Historical Consumption

Record cylinder usage over several weeks. Look for patterns in weekday, weekend, seasonal, and peak-period consumption.

Establish a Replenishment Point

Do not wait until the entire reserve is almost depleted before placing an order.

Set an internal threshold at which replacement cylinders should be arranged.

Maintain Reserve Capacity

The quantity of reserve LPG should be planned according to consumption, delivery schedules, and business requirements.

Consider Emergency Support

Unexpected demand increases, delivery disruptions, equipment changes, or special catering orders can affect normal consumption.

Your supply arrangement should account for these possibilities.

For central kitchens using long-term commercial supply arrangements, it is also useful to understand the terms surrounding pricing, delivery schedules, equipment responsibilities, and service support. See How LPG Supply Contracts Work in Singapore.

LPG Safety Equipment for Central Kitchens

A central kitchen's LPG system should include the safety provisions applicable to its installation.

SCDF's current Fire Code includes requirements for gas leak detection and automatic shut-off arrangements for applicable LPG piping systems. A gas leak detection system is designed to activate an alarm and automatically shut off the gas supply when a leak is detected.

Depending on the installation, the system may also include:

• Emergency shut-off valves

• Solenoid isolation valves

• Pressure regulators

• Fire extinguishers

• Warning signage

• Suitable cylinder housing

• Ventilation provisions

• Fire suppression or sprinkler protection where applicable

The exact requirements depend on the premises and installation design.

LPG Piping and Pressure Management

LPG needs to reach every appliance at the correct pressure and flow.

An undersized or poorly planned piping system may affect appliance performance, particularly when several appliances are operating simultaneously.

The design should take into account:

• Total gas demand

• Pipe length

• Number of appliance connections

• Required pressure

• Pressure-drop considerations

• Regulator capacity

• Future appliance additions

Piping should also be routed and installed according to the applicable requirements.

For commercial gas work, EMA states that gas service work such as constructing, altering, repairing, or renewing gas pipes and fittings is carried out by licensed Gas Service Workers within the scope of their licence.

How to Improve LPG Efficiency in a Central Kitchen

Reducing unnecessary LPG consumption does not always require replacing the entire system.

Start by monitoring actual usage and kitchen performance.

Maintain Burners Properly

Dirty or poorly adjusted burners can affect flame quality and cooking performance.

Monitor Unusual Consumption

A sudden increase in cylinder usage may indicate changes in production, appliance performance, operating patterns, or a system issue.

Match Appliances to Production

Running unnecessarily large burners for small cooking tasks can waste fuel.

Schedule Preventive Maintenance

Regularly inspect regulators, valves, hoses, burners, piping, and other relevant equipment.

Use Consumption Data

Monthly LPG records can help identify trends and support better delivery planning.

Common LPG Planning Mistakes in Central Kitchens

Planning Storage Too Late

Cylinder placement should be considered while designing the facility, not after renovation is completed.

Underestimating Peak Demand

A system that handles average demand may struggle during peak production.

Ignoring Future Expansion

Adding appliances later may require changes to the LPG system.

Ordering LPG Only When Cylinders Are Empty

Last-minute ordering creates unnecessary operational risk.

Choosing Equipment Based Only on Initial Price

The complete LPG solution should be considered, including installation, safety, maintenance, delivery, and long-term support.

Using Unlicensed Professionals

Gas installation work should be carried out by appropriately licensed professionals. EMA advises consumers to engage licensed workers for piped gas appliances and gas installation work.
