Dura
7 + Swimming Pool Air Heat Pump Heater (7 kw / 24000 Btu)
DURATECH® heat pumps utilize the sun’s
free heat by collecting and absorbing energy from the
outside air. This energy is then transferred to the pool
water. Your existing pool pump circulates the water through
the heater and warms the pool. The unit contains a fan that
draws in outside air and directs it over the surface of the
EVAPORATOR (energy collector). The liquid refrigerant within
the EVAPORATOR coil absorbs the heat from the outside air
and the refrigerant becomes a gas. The warm gas passes
through the compressor where it is compressed to form a very
hot gas, which then passes through the CONDENSOR (water heat
exchanger). It is here that the heat exchange occurs as the
hot gas gives up the heat to the cooler swimming pool water
circulating through the coil. The pool water becomes warmer
and the hot gas is cooling down as it flows through the
CONDENSOR coil, returns to its liquid form and, after
passing through the expansion valve, the whole process
begins again. The use of a highly efficient, low sound
rotary or scroll compressor, a low noise fan and an
oversized heat exchanger, makes the unit to be extremely
quiet in operation. Example: the DURA 8 at 10m distance
gives only 32 db(A). The Dura range comes in two formats the
standard and Dura+ range, the key differences being the Dura+
range will work down to a lower outside temperature -10*c
and have a higher COP range over their operating
temperature.
