Storage tanks

DHW heat pumps

TECHNICAL FEATURES:

Series of 3 models in 2 size for nominal storage capacity of 180 and 270 liters, composed of :

• Steel tank with double layer vetrification.
• High thickness foamed polyurethane insulation.
• External lower cover in grey ABS.
• Air-to-water heat pump system (R134a) composed of hermetic rotary compressor, condenser wrapped outside the boiler free from fouling and freon-to-water contamination, air evaporating finned coil, adjustable flow radial fan; upper cover in black ABS.
• Auxiliary electric heater automatically switched depending on outside air temperature.
• Anti-corrosion magnesium anode.
• Auxiliary coil for use in combination to boiler or solar panels (CRE-PWW).
• Double auxiliary coil for use in simultaneous combination to three different energy sources (CRE-PEP).
• Built-in electronics with LCD display.

Electronic control:

• User display for operating modes settings.
• Smart self diagnosis for alarms check.
• Operating time recording.
• Setting of set-point water temperature for Automatic and/or Manual operating mode.
• Management of the defrost cycle.
• Management of the anti-bacterial cycle, for elimination and preventing formation of legionella.
• Automatic activation of alternative energy source.

System storage tanks hot and cold

Storage units used as plant separators or energy storage, are all class A insulated with thick closed-cell rigid polyurethane free of and non removable CFC and HCFC with fire resistance Class B3 according to DIN4102.

HOT WATER STORAGE TANKS

Gli accumuli per acqua calda in combinazione con i preparatori istantanei vengono utilizzati per la produzione di acqua sanitaria. Sono tutti in classe A isolati con poliuretano rigido di forte spessore a cellule chiuse esente da CFC e HCFC non removibile con resistenza al fuoco Classe B3 secondo DIN4102. Si possono avere con singolo scambiatore fisso PHW1 oppure due scambiatori PHW2.

Hot water buffer tanks with instantaneous DHW production

The IDHW series hot water storage tanks have the combined flywheel-producer system with fixed heat exchangers inside the flywheel ( depending on the model) and corrugated stainless steel pipe for semi-rapid DHW production. They are all Class A insulated with thick closed-cell rigid polyurethane free of CFCs and non-removable HCFCs with Class B3 fire resistance according to DIN4102. They are available with a single fixed IDHW1 heat exchanger or twoI DHW2 heat exchangers.

dhw storage tank with fixed spiral heat exchanger

The product is equipped with one or two internal coils for DHW production, connectable to traditional and alternative heat sources such as energy recovery systems, solar thermal plants, etc. Fixed spiral heat exchangers with S235JR EN10025 carbon steel tubes welded to the tank. Internal anti-corrosion treatment with vitrified enamel coating, suitable for operation in aggressive environments and high working temperatures, approved for use with potable water.

DHW series with fixed (single or double) spiral heat exchanger and DHWM series with oversized fixed spiral heat exchanger.

istantaneous water heaters

The PSW are istantaneous DHW production modules that used a brazed stainless stelle plate heat exchanger and are used in combination with inetial storage tanks. Domestic hot water temperature is regulated by tehrmostatic mixing of the fluid in the primary circuit. the primary circuit circulator is controlled by a flow switch located on the DHW and electrically connected in series.
