21Kw Model

THE IDEAL SOLUTION...

for heating your swimming pool, Jacuzzi or spa
 

The energy is collected from the air outside and transferred to the pool water.

For each kW consumed by the DURATECH® heat pump , 4 to 5 kW are returned to the pool.

The DURATECH® heat pump has to be installed outside and will heat the pools from April to October.

The DURATECH® heat pump will even work with outside temperatures as low as -5°C.

CONSTRUCTED FOR DURABILITY AND LONGEVITY

Using advanced and high quality materials like PVC and “Duranium®” for the heat exchanger means it can resist to erosion from chlorine in the water.

Also, the “Duranium®” heat exchanger is oversized to improve efficiency.

EASY INSTALLATION

The unit is intelligently designed and remarkably compact for easy installation.
Example : The integrated flow switch will sense the water flow and automatically start the heater when the pool pump starts and stop it when the pump shuts off.

ENVIRONMENT

DURATECH® heat pumps are less harmful to the environment because 80% of the energy produced is collected from the outside air and therefore purely natural.

Also the gas used, R407C, has no harmful effect on the ozone layer.

ADVANCED CONTROL
The integrated microprocessor monitors all the sensors and controls the device without any intervention of the user. Electronic display and control with easy operation is standard.

RUNNING QUIETLY

The use of a high 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).

HOW DOES IT WORK?

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 CONDENSER (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 CONDENSER coil, returns to its liquid
form and, after passing through the expansion valve, the whole process begins again.
