For grease traps, an auto dosing system is commonly used to dose bio-enzymes and beneficial bacteria to break down fats, oils, and grease (FOG) before they accumulate.
Dual Power Protection System
The ADU9291P features a 2-in-1 power mode:
- AC Power (12V Malaysia Plug) – primary operating mode
- Battery Mode (8 × AA Batteries) – emergency backup use
The battery mode ensures the unit continues operating during power outages or unstable voltage conditions, reducing downtime and protecting the system from electrical damage.
👉 Built-in backup power ensures uninterrupted dosing when it matters most.
Smart & Automatic Operation
Equipped with a 24-hour real-time digital timer, the unit delivers automatic dosing at scheduled intervals.
- Consistent enzyme dosing
- No manual intervention required
- Operates even after business hours
👉 Set it once, and let the system handle the rest.

How an auto dosing system works
-
Stores the dosing liquid
- A container holds the bio-enzyme or treatment solution.
-
Programmable controller
- The controller is set to dose at specific times (for example, every night after business hours).
-
Dosing pump
- A precision pump injects the correct amount of liquid into the drain line or grease trap.
-
Treatment process
- The enzymes and bacteria digest grease and organic waste, helping prevent buildup.
Main components
- Digital timer/controller
- Peristaltic or diaphragm dosing pump
- Chemical or enzyme storage tank
- Suction tube with filter
- Injection tubing
- Non-return (check) valve
- Power supply

| Busy commercial kitchen | 4–8 times/day |
| 24-hour operation | Multiple programmable doses throughout the day |
Important note
An auto dosing system does not replace a grease trap. Instead, it enhances the grease trap's performance by continuously treating grease and organic waste. The grease trap still needs periodic inspection and cleaning because solids and non-biodegradable materials will continue to accumulate.
For best results, use a high-quality bio-enzyme specifically formulated for grease traps. Avoid dosing harsh chemicals such as bleach, acids, or caustic cleaners through the system, as they can kill beneficial bacteria and reduce treatment effectiveness.
