Integra

The ideal drain back system up to 200lt

Integra is a complete solar system foe hot water production, up to 200lt, the function of which is based on the drain back procedure.

More specifically, the thermally conductive liquid (which is used in proportion of 60% of water and 40% of liquid) circulates in a closed system without pressureand transmits heat from the solar collectors to the HSW (hot service water), through a heat exchanger. When the temperature in the solar collectors falls at lower levels that the one of the boiler or when the system temperature exceeds 85C/185F, the pump of the system closes and the thermally conductive liquid drains back from the collectors and the pipelines, depleting completely the closed circuit.

This way, the system remains safe from overheating, since the heat transfer in the boiler is interrupted, whilst, at the same time it is protected from the frost, there is no water to be frozen and to cause uncontrollable damage.

Integra provides the company or the family that chooses it a series of unconquerable advantages, such as:

• MONEY SAVING, thanks to the minimization of the damages and the use of fewer parts, because of the non-pressure function
• LOW COST OF MAINTENANCE since it has zero damage risk
• SIMPLE AND EASY INSTALLATION, since it abolishes many of the parts of a typical forced circulation system (expansion tank, control valve, pressure indicator, ventilator)
• REINFORCED PROTECTION FROM A BLACKOUT, since the circuit drains automatically and, that way, it remains protected until the power restoration, withoutstable water remaining, which may cause overheating or frost
• HIGHER EFFECTIVENESS, with produced hot water for a longer period of time, since it prevents the heat reversal during the night, so it minimizes the heat losses
