Coffee Roasteries in Southeast Asia Use LPG - Here's Why That's a Gas Safety Risk

Commercial coffee roasters across Southeast Asia run on LPG or natural gas. High heat, enclosed spaces, continuous operation - the risk is real. Here is a real installation using our FB-365 and EC-533R to protect one.

Coffee Roasteries in Southeast Asia Use LPG - Here's Why That's a Gas Safety Risk

Coffee Roasteries Run on Gas. Most Don't Have Gas Detection.

The specialty coffee industry is growing fast across Southeast Asia.

Vietnam. Thailand. Indonesia. Philippines. New roasteries opening every month.

Almost all of them run on LPG or natural gas. A commercial roaster burns gas continuously at high temperatures - sometimes for 8 to 10 hours a day.

The problem: most of these facilities have no gas detection system.

Not because the operators don't care. Because nobody told them it was necessary.

Why This Is a Real Risk

A gas leak in a roastery is more dangerous than in a typical restaurant kitchen.

The room is enclosed. Roastery rooms are often purpose-built with thick walls and controlled airflow for consistent roast quality. If gas accumulates, it accumulates fast.

The equipment runs hot. A commercial roaster drum reaches 200°C and above. Any ignition source is right there.

Operation is continuous. Unlike a restaurant burner that gets turned off between meals, a roaster may run for hours without staff actively monitoring the gas connection.

The gas connection is complex. Hoses, regulators, burner valves - more connection points means more potential leak points.

What a Proper Setup Looks Like

This is a real installation from one of our clients - a commercial coffee roastery in Southeast Asia.

The yellow gas supply line runs along the wall to feed the roaster burner.

On the gas pipe itself - the white unit with the brown label - that is our FB-365 gas detector. Mounted directly at the gas source, exactly where detection matters most.

On the wall above the gas panel - the blue control unit - that is our EC-533R alarm controller. It receives the signal from the FB-365 and controls the alarm output and automatic shutoff relay.

Clean installation. Every component in the right place.

How the System Works

Step 1 - Detection FB-365 mounted directly on the gas pipeline detects LPG or natural gas at 25% LEL. Well before dangerous concentrations can build in the roastery space.

Step 2 - Alert 85dB alarm activates immediately. The EC-533R controller panel shows the alarm status. Roastery staff hear and see it - even over roasting noise.

Step 3 - Automatic Shutoff EC-533R triggers the automatic shutoff valve on the main gas line. Gas supply closes within 15 seconds. No manual intervention needed.

The roasting operation stops. The risk is contained. Staff respond.

For Roastery Operators in Southeast Asia

If you are running a commercial roastery in Vietnam, Thailand, Indonesia, the Philippines, or anywhere across Southeast Asia - and you are using LPG or natural gas - this is the minimum setup we recommend:

  • FB-365 mounted at the roaster gas connection point
  • EC-533R controller on the wall
  • Automatic shutoff valve on the main supply line

Simple. Reliable. KGS certified Korean equipment.

For larger roasteries with multiple roasters or zones, the EC-536R (6-channel controller) gives full coverage from one panel.

The roastery in these photos built their gas safety system the right way - from the start, not as an afterthought.

If you are still running your roastery without gas detection, now is a good time to fix that.
