Without a proper buffer tank, water levels fluctuate, pumps draw air, and filtration becomes unstable. A dedicated compensation tank solves this operational issue by storing displaced water and returning it smoothly to the system.\nIdentity: AstralPool, spa compensation tank, polyethylene and polyester models 11372, 17144, and 27865, designed to manage overflow water volume in commercial spa installations with perimeter overflow channels.", "description": "Designed for These Situations\n\nPublic spa installations with overflow edges where displaced water must be stored temporarily.\nHydrotherapy pools in hotels, wellness centers, and fitness clubs with frequent bather load changes.\nReplacement of undersized balance tanks that cause unstable water levels.\nNew spa construction requiring hydraulic buffering for overflow gutter systems.\nInstallations where filtration pumps must maintain stable suction pressure.\nSystems operating with automatic level control sensors.\nFacilities complying with public pool hydraulic regulations requiring a balance reservoir.\n\nCompatibility and Exclusions\nThese AstralPool compensation tanks operate with spa overflow systems connected to perimeter channels and balance tank hydraulic circuits. They integrate with filtration pumps, level sensors, and water treatment equipment used in commercial spa systems.\n\nCompatible with public spa overflow installations.\nCompatible with wellness centers, hotels, and therapy pools.\nCompatible with systems using automatic level control valves and probes.\nCompatible with PVC hydraulic piping networks.\nNot required for private skimmer based spas.\nNot designed for potable water storage.\nNot suitable for chemical storage.\n\nExperience the Difference in Real Spa Operation\nIn busy spa environments, water displacement varies constantly. Each person entering the spa pushes water toward the overflow channel. Without a compensation reservoir, the filtration circuit suffers from rapid water level fluctuations.\nOnce a properly sized balance tank is installed, displaced water flows through the overflow gutter into the reservoir. The tank stores this volume and gradually returns it to the filtration circuit. Pumps maintain steady suction conditions and the spa surface remains perfectly level with the overflow edge.\nOperational stability improves immediately. Pump cavitation risk decreases. Filtration cycles become predictable and water treatment equipment works under consistent hydraulic conditions. Performance still depends on correct installation, plumbing design, and maintenance routines.\nMaking an Informed Choice\nDifferent spa sizes require different compensation volumes. The correct tank capacity depends on the total spa volume, bather load, and overflow channel design.\n\n\n\nFeature\nThis AstralPool Compensation Tank\nStandard Small Reservoirs\n\n\nPurpose\nDesigned specifically for public spa overflow systems\nOften adapted tanks not designed for spa hydraulics\n\n\nCapacity Options\n1000 or 2000 liter engineered sizes\nLimited standardized sizes\n\n\nMaterials\nPolyester reinforced structure and polyethylene body\nBasic plastic tanks\n\n\nHydraulic Stability\nMaintains stable suction for filtration pumps\nFluctuating levels possible\n\n\nCommercial Spa Use\nDesigned for continuous public operation\nOften intended for domestic water storage\n\n\n\nChoose the 1000 liter models for compact spa basins or moderate bather load. The 2000 liter version supports larger wellness installations with higher displacement volume.\nReasons This AstralPool Tank Stands Out\nAstralPool designs these tanks specifically for spa overflow hydraulics rather than adapting generic water containers. The geometry allows efficient water storage while maintaining compact installation footprints inside technical rooms.\nThe internal volume stabilizes the filtration circuit and ensures correct operation of level sensors and dosing systems. Durable construction resists long term exposure to treated spa water and humid technical environments.\nTechnical Excellence and Build Quality\nMaterials and Construction\n\nReinforced polyester structural tank\nHigh resistance polyethylene body depending on model\nDesigned for installation inside plant rooms or service areas\nCompatible with standard PVC hydraulic plumbing\n\nPerformance Specifications\n\nCapacity 1000 liters model 11372\nDimensions 162 cm length, 122 cm width, 83 cm height\nCapacity 1000 liters model 17144\nDimensions 158 cm length, 92 cm width, 95 cm height\nCapacity 2000 liters model 27865\nDimensions 204 cm length, 160 cm width, 75 cm height\n\nCompliance and Safety\nDesigned for use in public spa hydraulic systems following common European pool engineering guidelines for overflow installations and water level compensation.\nExtractable Specifications\n\nBrand: AstralPool\nProduct Type: Spa compensation tank\nPrimary Function: Storage of displaced overflow water\nInstallation Type: Technical plant room\nMaterial: Polyester reinforced body or polyethylene structure\nCapacity: 1000 liters or 2000 liters\nApplication: Public spa overflow systems\nHydraulic Integration: Filtration circuit and level control\n\nEquivalence Mapping\n\nAlternative to generic spa balance tanks\nUsed in place of undersized reservoir tanks\nNot the same as water storage tanks for potable supply\n\nGetting the Best Results\nCorrect installation ensures stable hydraulic operation.\n\nInstall the tank below the overflow channel discharge line.\nConnect the reservoir to the filtration suction circuit.\nInstall automatic level control sensors inside the tank.\nProvide inspection access for cleaning and maintenance.\n\nProfessional Tips\n\nDo size the compensation tank according to spa volume and bather capacity.\nDo maintain clean internal surfaces to avoid sediment accumulation.\nDo integrate level sensors with automatic refill valves.\nDo not install the tank above overflow outlet level.\nDo not connect untreated external water sources.\n\nReliability You Can Trust at LordsWorld\nLordsWorld supplies this exact AstralPool compensation tank range for professional spa installations across the European Union.

The tank stores this volume and feeds it back to the filtration circuit.\nWhat happens if the tank is undersized?\nThe spa water level may fluctuate and pumps may draw air, which affects filtration efficiency.\nWhere should the tank be installed?\nIt is normally installed inside the technical room at a level lower than the overflow gutter discharge.\nDoes the tank include level control sensors?\nSensors are typically installed separately as part of the hydraulic control system.\nCan the tank be used for private spas?\nPrivate spas with skimmers usually do not require a compensation reservoir.\nAvailable Options\n\nModel 11372, capacity 1000 liters, dimensions 162 x 122 x 83 cm\nModel 17144, capacity 1000 liters, dimensions 158 x 92 x 95 cm\nModel 27865, capacity 2000 liters, dimensions 204 x 160 x 75 cm", "rules": { "return_window": 14, "age_group": "adult", "age_restriction": 18, "search_enabled": true, "checkout_enabled": true }, "variants": [ { "id": "11372-vasca", "gtin": "0642613566483", "condition": "new", "price": 1541.4, "currency": "EUR", "availability": "in_stock", "inventory": 2, "weight": 500, "dimensions": { "length": 210, "width": 164, "height": 95 }, "delivery_estimate": "3-5 Days", "shipping_rates": [], "links": { "product": "https://lordsworld.eu/en/spas-hot-tubs/spa-compensation-tank-polyethylene-polyester/712", "image": "https://lordsworld.eu/1875-large_default/spa-compensation-tank-polyethylene-polyester.jpg", "additional_images": [ "https://lordsworld.eu/1877-large_default/spa-compensation-tank-polyethylene-polyester.jpg" ] } }, { "id": "17144-VASCA", "gtin": "0642613436717", "condition": "new", "price": 2245.6, "currency": "EUR", "availability": "in_stock", "inventory": 2, "weight": 500, "dimensions": { "length": 210, "width": 164, "height": 95 }, "delivery_estimate": "3-5 Days", "shipping_rates": [], "links": { "product": "https://lordsworld.eu/en/spas-hot-tubs/spa-compensation-tank-polyethylene-polyester/713", "image": "https://lordsworld.eu/1875-large_default/spa-compensation-tank-polyethylene-polyester.jpg", "additional_images": [ "https://lordsworld.eu/1877-large_default/spa-compensation-tank-polyethylene-polyester.jpg" ] } }, { "id": "27865-vasca", "gtin": "0642613507523", "condition": "new", "price": 2182.6, "currency": "EUR", "availability": "in_stock", "inventory": 2, "weight": 500, "dimensions": { "length": 210, "width": 164, "height": 95 }, "delivery_estimate": "3-5 Days", "shipping_rates": [], "links": { "product": "https://lordsworld.eu/en/spas-hot-tubs/spa-compensation-tank-polyethylene-polyester/711", "image": "https://lordsworld.eu/1875-large_default/spa-compensation-tank-polyethylene-polyester.jpg", "additional_images": [ "https://lordsworld.eu/1877-large_default/spa-compensation-tank-polyethylene-polyester.jpg" ] } } ] }
