®3Tech and LionRock Power3Tech manufactures gensets under the brand name

®LionRock Power. The LionRock® diesel generator sets are using Perkins engines coupling with Leroy-Somer alternators as standard. However, engines and alternators are available for special requirements. As

®an independent manufacturer, LionRock Power can customize solutions to meet demanding specifications.

Quality is value3Tech often provides off-grid solutions where the generator must run continuously for long periods. That's why the ver y high quality engineering of

®LionRock Power is so important. Efficient fuel consumption and low maintenance means long term value for our customers.

Professional service3Tech has thousands of generators in stock at our warehouses, ready to deliver anywhere in the world. With knowledge, experience and an extensive service network, 3Tech's dedicated engineers and technicians always deliver reliability, value and professional customer service.

Customized solutions3Tech supplies customized diesel generators to telecom operators, especially in Africa where we work closely with the large Chinese telecom equipment suppliers, Huawei and ZTE. The generators are mostly used to power the base transceiver stations (BTS) that make up mobile telephone networks. These BTS must operate 24 hours a day but are often located in places with intermittent or non-existent electricity grid supply making a reliable, independent power supply essential.

LionRock Power®

LionRock provides a complete range of diesel generators ®

from 7.5kVA to 3,250kVA with a range of famous engines from Perkins, Lister-Petter, Kubota or Deutz, for example. Skilled electrical engineers custom design specialized power systems for diverse applications, with a special focus on telecom solutions. Compact units combine genset, canopy, fuel tank and ATS and can be customized to extend maintenance intervals to 1,000 hours.

All-In-One Modular GensetLionRock modular all-in-one diesel genset design ®

includes batter y cabinet, bulk fuel tank and noise reduction canopy. The module provides unique benefits to our customers and meets sophisticated requirements for cell sites. The modular design can be customized to meet specific requirements but has shorter deliver y time compared to tailor made gensets. The all-in-one unit decreases the need for piping and wiring at the installation site and provides stability and ease-of-use.

®LionRock gas engine generators use natural gas, the cleanest fossil fuel available, to provide the most efficient way of using the available energy. Electricity is one of the best way to transfer energy from the generating point to the user point. In addition to the high

®electrical efficiency, LionRock gas engine generators also offer excellent heat recovery to meet various thermal demand to achieve over 85% total efficiency throughout the whole range of products.

®LionRock gas engine generators as well as heatrecovery equipment can be packaged within standard shipping containers for easy and quick deployment of the system on site. The design is completely modular and allow easy integration and expansion at any time without scarifying any efficiency reduction.

Other than normal 400V, 50Hz system, high voltage at 11kV is also available in exactly the same footprint of the low voltage equivalent.

In addition to natural gas, biomass gas, coal seam methane etc. are some other example of successful systems delivered by 3Tech.

®Currently, LionRock offers two ranges of gas engine generator products. One series cover rating up to 800kW using the latest German digital combustion control technology. With the latest microprocessor technology and data collection facility, the combustion process will be optimized through analysis of operating data and implementing the fuel and spark ignition timing control. That is why we can achieve the highest electrical efficiency of this power range.

Other benefits including optimised lube oilmanagement and excellent consumption,

maximum availability and highest reliability for longer operating life.

The 1000kW gas engine generator is a completelyChina developed technology. Output power isconservative for extended operating life and highreliability. Unlike other Chinese product, first class control components are used and tuned by the world class engine experts.

Other than the high efficiency and reliable operation of the 1000kW class gas engine generator set, owner will benefit from the most competitive parts and services support program offered by 3Tech.

3Tech also offers solution of combine cycle usingsteam turbine with multiple units of the gas engine.

GAS ENGINEGENERATORS




Solar3Tech is experienced in grid connection procedures and familiar with power company requirements. Designing a solar power system that is efficient, optimized and user-friendly requires expertise. 3Tech has qualified staff with the practical experience to provide professional design, installation and monitoring services.

Solar PV panelsWhen the Architectural Services Department of the Hong Kong Government decided to put the roof of their APB Centre in Hung Hom to productive use, they turned to 3Tech to design, supply and install this impressive array of solar PV panels.

This CLP grid-connected system uses 104 monocrystalline panels by Suntech to cover an area

2of 153m . Each panel is rated at 175Wp (under standard test conditions) and the system generates on average about 72kWh of electricity per day.

2That is a saving of around 15 tonnes of CO annually or 375 tonnes over the system’s expected 25 year lifetime. Typically, solar PV panels will repay the carbon emissions from their manufacture in 1 to 2 years.

Professional designConnecting to the grid requires sophisticated inverters, protected devices and meters to monitor power quality. To maximize the solar energy output, the panel frames face south and are angled up at 22 degrees to face the sun. All panel frames are hot-dip galvanized steel to survive the hot and humid weather in Hong Kong. The system employs three inverters by SMA to convert the direct current produced by the PV panels to three-phase alternating current matching the mains electricity supply. 3Tech also installed a monitoring system to show the real-time irradiance level and power output.

Solar Hot Water Panels3Tech installed solar hot water panels on the roof of the Electrical and Mechanical Services Department of the HK Government. These are evacuated tube solar

2collectors covering an area of 56m and providing a odaily average of about 2,000L of hot water at 60 C.

Solar hot water panels use the sun's energy more efficiently than PV panels and this installation saves about 40,000kWh a year. That's an annual saving of

220 tonnes of CO .

Sun TrackersSolar panels can be mounted on sun trackers, as shown at this installation in Sunny Bay, Lantau. A sun tracker points the panels toward the sun as it moves across the sky throughout the day and can increase the efficiency of PV panels by as much as 40% in some locations. Sun trackers outper form in the morning and late afternoon when sunlight would be incidental to a fixed array, but offer no advantage in cloudy conditions.

At Sunny Bay 72 panels (Sharp monocrystalline, 170Wp) are mounted in 8 arrays, each on a Lorentz sun tracker. This model employs a timer control but other types use light or heat sensitivity to track the sun and can move on either a single or double axis. Additional capital and maintenance costs must be weighed against the potential increase in efficiency.

BIPVBuilding integrated PV (BIPV) is ideal for canopies and skylights. Solar PV cells are laminated between two sheets of glass and used in place of conventional panes of glass. This BIPV installation is found at the librar y of St. Paul’s Co-Ed College Primary School and is rated at 8kWp.

This attractive skylight not only generates power but also provides shade resulting in lower costs for air-conditioning. It demonstrates to parents and students that the school cares about energy efficiency.

Competing TechnologiesThe two leading solar PV technologies are both silicon based: cr ystalline and amorphous thin film. Each has its own characteristics.

Town Island lies off the coast of Hong Kong and is home to a rehabilitation center. This remote island is not connected to the grid and has been powered by diesel generators with fuel transported by sea.

To allow for redevelopment, the center applied to CLP for a permanent electricity supply. For ecological reasons it was decided that the best solution was a renewable power system.

3Tech designed and built a hybrid system comprising 180kW of solar PV panels and two 6kW wind turbines backed up by a diesel genset and maintenance-free batteries. The system includes data management and remote monitoring and is the biggest hybrid power system in Hong Kong. It is

2calculated to save up to 262 tons of CO emissions annually.
