EXPANSION VESSEL


An expansion vessel is necessary to absorb the expansion of the solar fluid when high temperatures are reached in the solar collector. Available sizes are 24 and 35 litres.

Sales Codes:
SOL502EXP 24 litre expansion vessel
SOL503EXP 35 litre expansion vessel

INTERMEDIATORY VESSEL
The European VDI 6002 directive recommends that an additional vessel is fitted when the contents of the piping between the collectors’ field and the expansion vessel is lower than the 'wet' side volume (between the expanded diaphragm and the vessel inlet). This minimum requirement is rarely fulfilled in the case of solar systems with short pipe runs. The intermediatory vessel effectively protects the membrane against excessive temperatures that could damage it.

ANTI-SCALD MIXING VALVE



Anti-scald (mixing) valve must be fitted close to the hot water outlet of the solar tank so that delivery to the taps does not exceed 65ºC

AIR VENT AND ISOLATION VALVE


An automatic air vent should be fitted at the highest point in the solar circuit system in order to remove air from the system during commissioning. The isolating valve should be fitted before the air vent and isolated once the system has been commissioned.

SOL501AIR Air vent
SOL505STP Isolating Valve

GLYCOL SOLAR ANTI-FREEZE


The heat transfer fluid used in a solar circuit is normally a mixture of water and a polypropylene glycol anti-freeze. The glycol anti-freeze also contains an additive to protect against corrosion and evaporates at higher temperatures than water to allow higher system temperatures.

Firebird recommends a 40% glycol to 60% water mix to ensure frost protection to circa -25ºC.

SOL506FFL Tyfocor L Anti-freeze - Flat plate
SOL507VFL Tyfocor LS Anti-freeze - Vacuum tube

1M STAINLESS STEEL FLEXIPIPE



Firebird can also supply two 1m stainless steel flexi pipes which are connected to the flow and return side of the collector array. The flexible pipe saves the installer having to make complicated pipe bends through the roof of the house. Fittings are included to connect the pipe to the solar collectors.
