Evacuated Tube Solar Collector
Evacuated Tube Solar Collector
The evacuated tube solar collector is composed of a copper manifold connected to a series of evacuated tubes. Each evacuated tube is made up of 2 layers of glass with the inner layer coated with a solar energy absorbing layer. Each evacuated tube contains a copper heat pipe which converts the sun's energy into thermal energy and diverts it into the manifold. The tubes are sealed to prevent water or air from entering the vacuum space between the two layers of glass. The manifold and the tubes are placed on a frame with an angeled bracket which angles the collector at 45 degrees in order to install the collector on a flat surface. It can also be installed on a slanted roof or vertical wall without the angled bracket. This is called a "flush mount" installation.
Each tube can still heat up to extremely hot temperatures even in ambient temperatures of -45 degrees Celsius. This is due to the two layers of glass with a vacuum in between. If a tube were to accidentally break the evacuated tube solar collector will still operate without causing an leaks. Replacing a tube is a quick and simple process.
The evacuated tube solar collector is used to heat pools, hot tubs, floors, air and domestic hot water. Solar domestic hot water systems are used to heat water for homes, restaurants, malls, offices, farms, cottages and wherever hot water is needed.

Solar Heat Exchanger Tank
SHC-HET-200
The heat exchanger tank lined with stainless steel and insulated with polyurethane foam. The heat exchanger tank heats water via a copper heat exchanger which is located inside the tank. Heating fluid is pumped through the heat exchanger where the fluid releases its heat to the water inside the tank. Once the water inside the tank is heated, it rises to the top of the tank where it flows into the current heating system. This process is called thermosyphon.
The heat exchanger tank is placed near the current water heating system. For a domestic hot water system the tank is placed in the utility room of a home or building. For example, for heating water in a home the tank is placed in the basement adjacent to the current hot water system. The hot water in the heat exchanger tank is diverted into the current hot water system where, if required, it can be heated further. This configuration reduces the need for the current hot water system to be turned on to heat the water and thus reduces greenhouse gas emissions and your energy bills.
For floor heating the heat exchanger tank is placed near the floor heating system. The hot water in the heat exchanger tank is diverted into the floor heating system. If a floor heating system is not present, the heated water is diverted directly into the floor heating pipes.

Solar Station
SHC-SST
The solar station is made up of various components. These components are specifically designed for a high temperature closed solar loop. The pump is used to circulate the heating fluid through the closed solar loop. The purpose of the expansion tank - seen in red - is designed to allow for expansion of the heating fluid. If the heating fluid overheats it begins to expand and will consequently put strain on the pipes. The expansion tank absorbs this expansion to prevent any damage to the system.
The pressure gauge and pressure relief valve display the pressure of the heating fluid and if a certain pressure is exceeded the pressure relief valve opens to release excess fluid. This is a precautionary method and if the system is properly designed the pressure relief valve will not open. The flow meter displays the flow rate of the heating fluid
The controller's purpose is to sense the temperature difference between the controller and the heat exchanger tank. Once there is a positive temperature difference the pump starts to circulate the heating fluid through the loop thus heating the water. Once the temperature of the collector is close to the temperature of the water in the tank the pump stops working.
