Float-activated AC Drainage Systems

Automatic, reliable condensate removal with simple mechanical control.
Float-activated systems use a buoyant float switch to automatically start and stop a pump based on water level, providing a robust, time-tested solution for condensate drainage. EKG Malaysia designs, supplies, and installs these reliable systems for applications ranging from single residential units to large commercial sump-based setups, ensuring fail-safe operation with minimal complexity.

How It Works:
A floating switch arm rises with the water level in a reservoir. At a preset "pump-on" height, it activates an electrical switch, starting the pump. As water is pumped out and the level drops, the float falls and breaks the circuit, stopping the pump.

Types of Float-Activated Systems:

• Integrated Unit Pumps: Common in small condensate pumps for split systems; the float and pump are in a single housing.

• External Float Switches: Used with separate pumps and tanks, allowing customization for large or custom sumps.

• Multi-Float Systems: Employ separate floats for pump activation, high-level alarm, and low-level cutoff in critical applications.

Key Advantages:

• Proven Reliability: Simple mechanical operation with no complex electronics in the wet area.

• Easy Troubleshooting: The float mechanism is visible and simple to test or clean.

• Cost-Effective: Generally lower cost than digital sensor-based systems.

• Durability: Withstands typical condensate conditions well when using appropriate materials.

Applications:

• Standard residential and commercial AC condensate removal.

• Centralized condensate collection sumps for multiple AHUs/FCUs.

• Backup or secondary drain pan safety systems.

• Industrial dehumidification where robust, simple control is preferred.

Design & Installation Considerations:

• Float Material: Must be compatible with condensate (often PVC or polypropylene).

• Switch Rating: Electrical rating must match the pump motor's current requirements.

• Tank Geometry: The tank must allow the float to move freely without obstruction.

• Maintenance Access: The float should be accessible for occasional cleaning or replacement.
