FloCal B Pump Station plus controller order code:LEPS2
Description: The Solar Pump station integrates all the necessary components for the efficient operation of a solar system. The components are all solar rated, and arranged within the insulated package ready to take flow and return connections.
Sensor Connection Boxes
Description: The C-CSCB and SE-SP10 sensor connection boxes with overvoltage protection device should be installed to protect the solar collector temperature sensors against induced overvoltages caused by lightning strikes or other external sources.
During a local thunderstorm, voltage peaks which could potentially destroy the sensor are induced in the sensor cable. The protection diodes in both the C-CSCB and SE-SP10 limit these overvoltages to a value harmless to the sensor. Both the C-CSCB and SE-SP10 connection boxes are IP65 rated and are suitable for mounting outside. Cable glands for the sensor cables are provided to facilitate weatherproof entry into the box.
Intasol Combi Diverter Valve
See Videos at bottom of page.
Description: The Intasol is a hot water diverter valve for use with combination boilers or instantaneous water heaters. This means that a solar system can now be linked with a combi boiler as back-up.
Cross-flow contamination is eliminated by the clever deployment of solar check valves integrated within the valve.
Technical Specification
* Maximum operating pressure: 10 bar static, 5 bar dynamic
* Connections: 15mm compression
* Maximum inlet pressure: 2:1
* Maximum operating temperature: 100°C
* Regulating temperature: 35-55°C
Thermostatic Mixing Valve
Storing energy from the sun in the form of hot water, can lead to water arriving at the taps at higher than normal temperatures. In some cases, the cylinder maximum store temperature can be raised to as high as 80°C, which if delivered through a tap or any outlet, would present a severe danger of possible scalding.
The Solar Thermostatic Mixing valve is designed to temper the water temperature to a safer level. Unlike the under basin, or bath/shower type valves we are familiar with on the market, the Solarmix is designed to function continuously at high temperatures, something a standard TMV2 valve could not cope with.
Fitted close to the HW outlet from the cylinder, the Solarmix blends the high temperature hot water with cold, to provide safe water supplies. Flow rates are also greater on these valves and are suitable for use on pressurised systems (please note though, they may not be suitable for use on some LP gravity DHWS).
Solar Thermostatic Mixing valves should not be installed instead of TMV2 or TMV3 valves, and are used in a different context to these valves.
Expansion Vessel order codes:exp18 exp24 exp35 exp50
As with any sealed system, the pumped circulation solar system has to have an expansion capability to cope with fluid expanding as the temperature increases. Also in the solar system, the expansion vessel diaphragm has to have the ability to work within higher temperatures than that expected of a standard heating vessel. Intaeco Solar Plus vessels and eres solar vessels have been designed to function in solar installations. System fluid capacity dictates what size vessel is used, though most domestic applications require a capacity of between 18 Ltrs and 24 Ltrs.
Eres solar vessels are rated to a maximum working temperature of 130°C, 10 bar, and welded steel vessel is supplied in a white powder coated finish.
Solar Intermediate vessel
Intermediate vessels are also being used more frequently now. These vessels are flow through inlet/outlet connection, and are installed before the main expansion vessel. The heat sink that the intermediate vessel provides reduces the working temperature at the diaphragm, and so extends the working life of the expansion vessel considerably.
Expansion Vessel Connection Kits order code:exM expA
Description: A pre-formed stainless steel flexible is also provided to connect the vessel to the system at the connection point provided on the Flo Cal Solar Pump and Control Station.
Intermediate Vessels & SolarSafe. The bracket is much more robust than is used with normal heating vessels of a similar size. Note the intermediate vessels are always fully flooded, so the weight should be considered, and this type of robust bracket used.
Motorised Valve order code: LEMV01
Description:The SF 2 port motorized zone valves and SF 3 port motorized diverting valves are powered by an electric actuator and have two operating positions depending on whether the motor is activated (energized) or not. The valves can be supplied with one or two auxiliary switches on request. These are activated when the valve switches and are usually linked to a pump to hold the pump off until the valve is open.
The valves are equipped with an external lever for manually positioning the shut-off ball in its central position.
Both the 2 and 3 port valves are rated to operate at temperatures up to 160°C. The internal ball used for closing or diverting is made of a material suitable for aqueous-glycol based fluids and the higher temperatures that can be experienced in solar thermal systems.
Solar Balancing Valve order code: SBV
For flow balancing, adjusting and control of flow in solar heating systems. Visual flow indicator and flow adjustment. All components rated for high temperatures as could be realised in this type of system. Rated to 130 C max working temperature.
Solar Air Vent order code:SAV
The air-scoop on the pump station provides air removal at the point of commissioning, but no automatic venting. The solar automatic air vent provides long term removal of air.
Usually being installed at the highest point in the system, near or next to the collector, means that the valve is in the area of the system where the most extreme temperature conditions are created, so in the manufacture of this product, using high temperature solar rated components is critical.
Use in conjunction with the Intaeco Solar ball valve to provide isolation so the AAV can be removed during maintenance without losing fluid.
Discal Air Valve order code:DV01
Deaerators are used for progressive removal of air or gas which is continually formed. Even the smallest particles of (micro bubbles) are captured and expelled.
The Deaerator is the single most efficient air removal method, and will ensure that time is saved during commissioning as well as preventing installer call outs to vent trapped air. Install before the pump to prevent air pockets being trapped at the impeller and disabling the pump. Most professional solar installers recommend this method of protection for long term system efficiency.
Safety Relief Valve
As with any sealed system or circuit, a safety pressure release valve is required as mandatory for safety, should the system pressure exceed its designed safe maximum.
As a safety device, it is critical that the valve can be relied on to act when required, in the case of solar systems, the valve to do this must be designed to function continuously at extremely high temperatures. All components of the Solar Safety Valve have been redesigned or tested to be solar rated. Installers should under no circumstances use standard design heating safety valves in solar systems.
Drain or Fill Valve
* High temperature solar rated valve for use with solar Glycol fluids.
* Complete with hose connection for alternate filling/drain valve
* Self sealing half-inch male system connection
* Removable lever
Flexible Pipe System order codes: FP16/15 FP/25
Making the connection between the solar collector on the roof, and the system below creates different set of problems for the installer. Yes, it can be achieved by simply using copper tube, but the high temperatures achieved (therefore traditional soft solder joints should not be used) difficult sets and bends required, and installation time are all factors.
The generally accepted method is to use a flexible, high temperature stainless steel pipe system. This can be used to enter the internal roof space to accommodate an easier connection to the copper flow and returns, or carry the fluid medium direct to the pump station (by far the easiest and most efficient method.
The most common type of SS flexible pipe is of an 'Annular' design, i.e., the corrugated form allows flexibility. The more efficient design is however 'Helical', where flexibility is achieved by using a spiral configuration. This eliminates the dead flow areas in the pipe created by the corrugations, and significantly increases achievable flow rates through the pipework, the benefit of which is the pipe can in some cases be of a lesser diameter. The other benefit is that a range of fittings can be used if necessary to make connections between the pipes, and eliminate the requirement for special tools to make flanged joints.
A one piece pipe run between the collector and the pump station removes the risk of leaks, either at time of installation, or later, when pipework has settled or undergone system expansion and contraction.
The pipe can be supplied in coils, or in pre-insulated twin pipe packs to set lengths. Being pre-insulated also offers other benefits, which can only be appreciated by those who have spent frustrating hours labouring on pushing metres of pipe through long lengths of this specially designed lagging which is specified for Solar installations.
Also note that the lagging should have additional attributes for above roof weatherproofing and a surface that will deter birds from causing damage (they sometimes see this insulation as suitable nesting material)
A full range of fittings is available for both helical and annular pipe.
