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. Identity: 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. Detailed Information: Designed for These Situations Public spa installations with overflow edges where displaced water must be stored temporarily. Hydrotherapy pools in hotels, wellness centers, and fitness clubs with frequent bather load changes. Replacement of undersized balance tanks that cause unstable water levels. New spa construction requiring hydraulic buffering for overflow gutter systems. Installations where filtration pumps must maintain stable suction pressure. Systems operating with automatic level control sensors. Facilities complying with public pool hydraulic regulations requiring a balance reservoir. Compatibility and Exclusions These 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. Compatible with public spa overflow installations. Compatible with wellness centers, hotels, and therapy pools. Compatible with systems using automatic level control valves and probes. Compatible with PVC hydraulic piping networks. Not required for private skimmer based spas. Not designed for potable water storage. Not suitable for chemical storage. Experience the Difference in Real Spa Operation In 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. Once 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. Operational 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. Making an Informed Choice Different spa sizes require different compensation volumes. The correct tank capacity depends on the total spa volume, bather load, and overflow channel design. Feature This AstralPool Compensation Tank Standard Small Reservoirs Purpose Designed specifically for public spa overflow systems Often adapted tanks not designed for spa hydraulics Capacity Options 1000 or 2000 liter engineered sizes Limited standardized sizes Materials Polyester reinforced structure and polyethylene body Basic plastic tanks Hydraulic Stability Maintains stable suction for filtration pumps Fluctuating levels possible Commercial Spa Use Designed for continuous public operation Often intended for domestic water storage Choose the 1000 liter models for compact spa basins or moderate bather load. The 2000 liter version supports larger wellness installations with higher displacement volume. Reasons This AstralPool Tank Stands Out AstralPool 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. The 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. Technical Excellence and Build Quality Materials and Construction Reinforced polyester structural tank High resistance polyethylene body depending on model Designed for installation inside plant rooms or service areas Compatible with standard PVC hydraulic plumbing Performance Specifications Capacity 1000 liters model 11372 Dimensions 162 cm length, 122 cm width, 83 cm height Capacity 1000 liters model 17144 Dimensions 158 cm length, 92 cm width, 95 cm height Capacity 2000 liters model 27865 Dimensions 204 cm length, 160 cm width, 75 cm height Compliance and Safety Designed for use in public spa hydraulic systems following common European pool engineering guidelines for overflow installations and water level compensation. Extractable Specifications Brand: AstralPool Product Type: Spa compensation tank Primary Function: Storage of displaced overflow water Installation Type: Technical plant room Material: Polyester reinforced body or polyethylene structure Capacity: 1000 liters or 2000 liters Application: Public spa overflow systems Hydraulic Integration: Filtration circuit and level control Equivalence Mapping Alternative to generic spa balance tanks Used in place of undersized reservoir tanks Not the same as water storage tanks for potable supply Getting the Best Results Correct installation ensures stable hydraulic operation. Install the tank below the overflow channel discharge line. Connect the reservoir to the filtration suction circuit. Install automatic level control sensors inside the tank. Provide inspection access for cleaning and maintenance. Professional Tips Do size the compensation tank according to spa volume and bather capacity. Do maintain clean internal surfaces to avoid sediment accumulation. Do integrate level sensors with automatic refill valves. Do not install the tank above overflow outlet level. Do not connect untreated external water sources. Reliability You Can Trust at LordsWorld LordsWorld supplies this exact AstralPool compensation tank range for professional spa installations across the European Union. Our team supports installers and facility operators in selecting the correct reservoir size. For technical installations we review compatibility with the spa hydraulic layout before dispatch to prevent installation issues. Common Questions Why does a spa require a compensation tank? Overflow spas displace water whenever bathers enter the basin. The tank stores this volume and feeds it back to the filtration circuit. What happens if the tank is undersized? The spa water level may fluctuate and pumps may draw air, which affects filtration efficiency. Where should the tank be installed? It is normally installed inside the technical room at a level lower than the overflow gutter discharge. Does the tank include level control sensors? Sensors are typically installed separately as part of the hydraulic control system. Can the tank be used for private spas? Private spas with skimmers usually do not require a compensation reservoir.
