MAX-TEC solar collectors convert direct
and diffused solar radiation into
usable heat energy. The collectors
efficiently collect and transfer this
energy to a special collector plate
through a rapid heat transfer channel
called the ‘heat-pipe’.
Situated in an evacuated glass tube,
this pipe is a highly insulated manifold
heat exchanger.
The collector plate
has a special coating using a semiconductive
layer that converts the maximum amount
of solar radiation into heat, whilst
experiencing very low radiation losses.
The heat-pipe has
a very low heat capacity but an exceptionally
rapid conductivity and therefore is
a very efficient and speedy heat conductor.
The special fluid inside the ‘heat-pipe’
evaporates when heated, transferring
heat energy upwards. The vapor condenses
inside a special heat exchanger (which
is located within a water manifold)
and the fluid then returns to its
original position due to gravity and
the cycle is repeated. The vacuum
in the glass tube, being the best
possible insulation for a solar collector,
suppresses heat losses and also protects
the system from external adverse conditions.
This results in exceptional performance
far superior to any other type of
solar collector.
Unlike some
other types of solar collectors, evacuation
tube systems still provide excellent
results on cloudy days because the
tubes are able to absorb the energy
from infrared rays that pass through
cloud cover. Wind and low temperaturesalso
have less effect on the function of
evacuation tubes due to the insulating
properties of the vacuum. The shape
of the tubes provides superior absorption
