	This water-bottling system from Shenzhen Angel Drinking has three washing stations and a filling capacity of 300 bottles per hour.

The latest designs can handle as many as 600 bottles in an hour and are equipped with features that promote cleaner water.

Under efforts to maintain competitiveness in the midrange and high end, China suppliers of water-bottling systems are gearing R&D toward improving product performance.

Most makers are boosting the speed and capacity, enabling models to handle up to 600 bottles per hour. This is more than six times higher than previous versions.

Water quality is likewise being emphasized. A number of companies are releasing units with a monoblock base that encloses the washing and filling tanks, preventing dust and other contaminants from entering the system.

Further, components that are in direct contact with the liquid are being made of corrosion-resistant stainless steel.

Three to five washing stations, which are capable of sterilizing the bottle's inner and outer sides simultaneously, are being incorporated in most releases. Some water-bottling systems even feature heating and drying functions for thorough disinfection.

For enhanced efficiency and accuracy, washing, filling and capping functions are fully automated using a programmable logic controller, a computer designed for multiple input and output processing.

Additionally, the device's reinforced construction allows it to withstand extreme temperatures, vibration and impact, which in turn aids in extending service life. Companies source PLC from Panasonic, Siemens and LG.

As regards production, most makers, including Aquaworks Co. Ltd, are reluctant to introduce new technologies due to the complex fabrication process. They fear upgrading might lead to the restructuring of the whole system, resulting in a substantial manufacturing cost increase.

Shenzhen Angel Equipment & Technology Co. Ltd is one exception. The supplier has invested recently in an anti-seepage machine, which can boost water utilization efficiency by more than 25 percent. This is seen as one way to reduce production outlay in the long run.

	The XG-100A model from Jiangmen Futian comes in stainless steel and is suitable for 3 or 5gal PET or PC bottles.

Among the suppliers interviewed for this report, Green-Aqua Equipment & Electrical Co. Ltd has launched the GRA series that uses advanced micronegative pressure technology for quick, steady and accurate filling.

Green-Aqua also offers the XG100 model featuring a liquid switch, which detects the water level in the tank and stops the filling process when the amount is too low. The product automatically shuts off when the working pressure reaches or is below 0.5MPa to prevent breakdown.

New water bottling systems from Shenzhen J&D Electrical Co. Ltd are equipped with five washing stations and a UV sterilizing light.

Shenzhen Angel Drinking Water Equipment Co. Ltd has introduced the CGF16-12-6 model fitted with pressurized filling nozzles that deliver fast and accurate dispensing with minimal dripping and leakage.

The latest designs from Jiangmen Futian Drinking Water Equipment Fty have a capacity of 450 bottles per hour and are suitable for 3 or 5gal PET or PC bottles.
