UNIT
COMPONENTS
Recovery circuit in the extraction air
This reversible circuit allows to recover the energy from the extractionair to heat the air in the pool. Hermetic scroll-type compressor with sound insulation, and integral protection of the motor temperature, assembled over antivibration mounts. Air circuit comprised of coils with copper pipes and aluminium fins, with polyurethane coating. Thermostatic expansion valve with external equalisation. Antiacid filter drier. Crankcase heater. Four-way cycle reversing valves. Liquid receiver and liquid sight glass.
Casing
Sandwich-panel casing made up in galvanized steel plate of 1 mm covered with polyester paint outside and inside, with glass fiber insulation of 25 mm. Support frame and hinged doors to access to the sections of the unit. Panels and doors with rubber joints to ensure tightness.
Indoor circuit
Direct expansion cooling coil with copper tubes and aluminium fins, with polyurethane coating. Condenser coil with copper tubes and aluminium fins, with polyurethane coating. Stainless steel condensates drain pan with drainage outlet. This pan is inclinated towards the drainage outlet so that the water does not stagnate in the pan, avoiding sanitary problems. Electronic EC plug-fans directly coupled with variable speed and flow sensor. Anti-corrosion treatment. Mixing box of 3 dampers, with motorized dampers and return EC plug-fan directly coupled with variable speed and flow sensor. Reusable air filters, assembled on a frame.
Protections
High pressure pressostat. Low pressure pressostat. Main door switch. Magnetothermic protection switches for the power line of compressors and fan motors. Automatic switch in the control circuit. Probe for mixing air temperature.
Main cooling circuits
Unit with three cooling circuits: • All circuits participate in the air dehumidification when evaporating on the 3 circuit coil. • One of the circuits is condensed over a special SMO-254 plate exchanger welded with copper, filled with pool water, recovering part of the energy from the evaporation process • The other two circuits condensate over two air coils located at the evaporator air outlet, heating the cold and dry air, before discharge over the optional hot water coil. Three hermetic scroll-type compressor, assembled over antivibration mounts, with thermal insulation and integral protection of the motor temperature. Thermostatic expansion valve with external equalization. Antiacid dryer filter.
Electric panel
Complete and fully wired electrical panel. Insulated panel cover to prevent condensation. Protection IP55. Main ground connection and power supply with neutral. Compressor and fan motor contacts.
