"A+Plus" System is a superior air purification technology, which applies an innovative technology called Photocatalytic Oxidation (PCO) to decompose the air pollutants, airborne bacteria and pathogens.
Purification Process
Pre-filter - Filters larger suspended particulates such as pollen, dust, hair, etc. and as a result extends the life-span of the HEPA filter.
HEPA (High Efficiency Particulate Air Filter) - Has strong filtration power, effectively removes small suspended particulates up to 0.3 microns, including bacteria, fungi, mold and allergen, etc. The filtration rate is up to 99.97%
Nano-photocatalytic Reactor - PCO decomposes harmful gases and volatile organic pollutants (such as formaldehyde and benzene, etc) into harmless substances (carbon dioxide and water) at room temperature. The PCO reaction also removes strong odours such as cigarette and other compounds, as well as effectively kill bacteria.
Special Maintenance Indicator for Filters and UV Light
The maintenance Indicator will light up to inform the user to change the appropriate parts (filters or UV light). This ensures the "A+Plus" System to always perform in the best condition.
Envirowash
The Enviro Wash is a high performance automatic wheel washing machine aimed at washing away the mud and grit adhered to the wheels of trucks when the truck is leaving a construction site. It provides a cost-effective solution for construction site to comply with the environmental requirements.
In general, most of the construction sites are using a water hose at the entrance of the site to clean manually the departing vehicles. By doing so, extensive labour force is used and a lot of water is consumed, In many occasions, the mud and grit adhered to the underside of the vehicle chassis and the inner wheels of the vehicles could not be removed effectively by the water hose.
The design of the Enviro Wash is capable of overcoming the above problems. When the trucks leaves the construction site and stops at the Enviro Wash, a built-in sensor will be automatically activated and the Enviro Wash is turned on such that high pressure water spray will clean the wheels of the truck from many different directions, i.e. from outside, inside and below the wheels to ensure the cleaning performance. spray water will be collected, cleaned and re-used again thus reduce the water consumption and eliminate the effluent disposal problem.

HKPC-STS
HKPC-STS is a packaged sewage treatment system designed for treating the waste water discharged from the toilets of specific locations that there is no direct connection of Government sewers. Examples of such locations are construction sites, remote schools, campsites, etc. HKPC-STS consists of an anaerobic chamber, an aerobic chamber and a sedimentation and disinfection chamber. The wastewater from, the toilets is firstly discharged into the aerobic chamber for the aerobic treatment process. In the aerobic chamber, soluble and suspended organic matters in the wastewater are absorbed and assimilated by the microorganisms growing on the surfaces of fill media. After aerobic treatment, the wastewater enters into the sedimentation and disinfection chamber in which sedimentation will take place and disinfecting agent will be added to the treated effluent before discharge.
Three standard models of HKPC-STS are available as follows:
