 Duratech Dura 14 Plus Heat Pump
Introducing the New Duratech Dura range of high quality, high specification, heat pumps. Duratech Dura Plus Heat Pumps can save you up to 80% in operating costs.
The Duratech Dura Plus Heat Pumps can pay for itself in just a few years with the operation costs savings alone.
Highly efficient and economical
The energy is collected from the air outside and transferred to the pool water. For each kW consumed by the Duratech Dura Plus Heat Pumps, 4 to 6 kW are returned to the koi pond.
Use
The Duratech Dura Plus Heat Pumps must be installed outside. It will heat your pond all year if you want and will even work efficiently with outside temperatures as low as -10°C with the Duratech Dura Plus Heat Pumps range.
The Duratech Dura Plus Heat Pumps have an extra feature a cooling mode, which allows the water to be cooled down by the Duratech Dura Plus Heat Pumps as well.
Environment
Duratech Dura Plus 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, R410a (DURA+) R407C (DURA), has no harmful effect on the ozone layer. The DURA heat pumps are very energy efficient, our DURA+ range even reach a COP value of 6.
Constructed for durability and longevity
Using advanced and high quality materials like PVC, stainless steel and titanium for the heat exchanger means it is resistant to corrosion through chlorine or salt. The heat exchanger is oversized to improve efficiency.
Easy installation and Advanced control
The unit is intelligently designed and remarkably compact for easy installation. 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. The integrated flow switch will sense the water flow and automatically start the heater when the pool pump starts and stops when the pump shuts off.
Running quietly
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).
Warranty
2 years warranty on parts and labour on all components.
How does it work?
The Duratech Dura Plus 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.
