As the key components of the solar collector, the evacuated tube is a product that is optimized in geometry and performance.
The tubes are composed of two concentric glass tubes which in each case are half spherically closed on one side and fused together on the other side.
The gap between the tubes is evacuated and afterwards hermetically plugged (vacuum Insulation).
In order to make solar power usable, the internal glass tube is provided on itsexternal surface with an environmentally friendly, highly selective layer and isthus designed as an absorber.
This coating is thus protected within the vacuum gap. It is an aluminum nitritesputter layer which is characterised by very low emission and very good absorption.

• Single family use for up to 6 persons • Farming and Camping areas • Shower at sports areas or swimming areas • Holiday residences
ADVANTAGES
• Evacuated tubes with German standard • Polyurethane foaming HFC-245FA blowing agent which
is harmless to ozone layer • Aluminum brackets, strong and durable
For the non-Pressurised thermosiphon system, its storage tank and evacuated tubes are Installed as one tinin building roof. Run by natural circulation, the system can work without electricity. The hot water flow rate of this kind mainly depends on height difference between the water tank and the hot water shower head.

DOMESTIC HOT WATER SYSTEM
The domestic hot water system is an active two loop system circulated bya pump with a controller. For this kind of system, the storage tank is separated with collectors. The collector is perfectly integrated on the roofor out of the window of the building, whereas the storage tank is installedinside the room. The piping between main components is made of copperwith high-temperature resistance insulation materials wrapped outside.
There are two types of this system. One is active system circulated by apump with controller. The other type is passive system circulated by thedifference of temperature and height between the tank and collector. Both of them have Pressurised tanks.
Domestic hot water system can provide hot water for 2 to 10 people, whilethe size of tank and collector area depend on the Individual requirement ofthe customer and the climate data at the place of installation.
ADVANTAGES OF PACIFIC SOLAR DOMESTIC HOT WATER SYSTEM:• High quality in design and construction • Automatic and comfortable hot water supply • High efficiency with CPC technology • Evacuated tube with high absorption and low emission • Modern building integrated system
S0LAR STATION

The solar station is a pre-assembled and completely sealed unit for using in solar thermal system. It is installedin the return flow line (cold side) of the solar circuit only.The flow in the solar circuit can be adjusted at the flowmeter in combination with the pumps stage. It can beused In both low flow and high flow solar systems.

DOMESTIC HOT WATER SYSTEM-FITTINGS
The solar controller is conceived for the control of domes-tic hot water systems consisting of evacuated tube collec-tor and solar hot water storage tank. It controls switchingon and off of the solar pump as sensing of the collectorand storage temperature. The solar controller permits operation of the solar system with water instead of ananti-freeze agent.

After finishing the installation of the complete solar system, including solar station, storage tank, solar controller and all necessary safety devices, the solar cir-cuit has to be rinsed thoroughly with suitable equipment. We recommend using the Solar Pacific filling and rinsingstation for the initial start up process.

SOLAR FILLING AND RINSING STATION
SPACE HEATING SYSTEM
Space Heating for every unit Space heating system cannot be designed and installed for each house. Large
scale project should be designed. One of the problems of such system is how to utilise the heat the project
gathered in summer time. As the hospital, hospital, school, hotel will use hot water all year round, the space
heating project can be combined with such sites to consume the extra heat in summer. Solar space heating
adopts the same principle of hot water collection. And the heated water will be used for space heating or
floor heating. Also the Pressurised or non Pressurised system can be used.
SOLAR POWER STATIONS
Solar power stations for houses for their lights
On grid or off grid solar power station can be designed by Pacific Solar. The solar panels can be installed for
each household or arranged together. Details should be provided by the Clients.
The above system is for small load from 10w to 180w home solar power system.
