OKSOL-150 is an integrated solar collector

that uses thermal solar power to

produce Domestic Hot Water.

The absorber, the forced recirculation

system and a DHW storage tank holding

150 litres of water are all included in

one single element. It uses photovoltaic

solar technology to supply the

recirculating pump®, making it a totally

independent system with no external power

requirements.

SOLAR SYSTEM WITH

INTEGRATED OKSOL-150 TANK

HOW DOES IT WORK?When solar radiation falls on

the collector, the collector

concentrates the heat and

transfers it to the heat-carrying

fluid circulating inside it. Its cover

shape and selective treatment

enable the whole surface of the

fluid-filled heat-carrying collector

to be made use of. As a result,

the solar radiation reaches

both the heat-carrying fluid and

the photovoltaic panel, which

generates electricity, causing the

recirculating pump to run and

the hot fluid to be conveyed to

the inside of the heat exchanger.

The heat is transferred from the

collector to the tank by means

of the pump controlled by the

photovoltaic panel and the heat

exchanger. On sunny days the tank

will heat up to maximum storage

temperature of 95ºC.

INDIRECT HEAT EXCHANGE SOLAR KIT

HOW DOES IT WORK?This kit regulates the recirculation

inlet to the home from the circuit

previously heated by the solar

collector. If the kit detects that

a tap has been turned on and

hot water is required, the flow

to the heat exchanger is opened

to preheat the domestic water

inlet. When the hot water tap is

turned off, the 3-way valve opens

the bypass again and shuts off

the flow to the heat exchanger.

The shut-off valves allow the

central recirculation system to be

completely blocked off at all the

inlets.

The indirect heat exchange solar kit is

designed for centralised solar heating

installations with distributed back-up

power. Each home has an individual back-up

power source and its own interior distribution

circuit supplying domestic water.

You may complete the totally regulated

installation with the solar domestic

water kit
