Ultra High Capacity Heat Pump 220kW KRY-220II Commercial Pool

The 220kW ultra high capacity pool heat pump (model KRY-220II) is a professional constant-temperature pool heating solution engineered for industrial-scale, Olympic-sized, and mega aquatic facilities. As a leading air-source industrial swimming pool heater, it delivers exceptional water temperature stability, maximum energy efficiency, and uncompromised long-term reliability for business clients including large water park developers, international hotel chains, Olympic training center operators, and government recreation project contractors. Centered on advanced heat pump technology, this unit transfers heat from ambient air to heat pool water instead of relying on direct electric heating, drastically cutting energy consumption while maintaining precise temperature regulation. With a dual-refrigeration circuit design, robust stainless steel casing, industrial-grade titanium heat exchanger, smart defrosting, and optional 380V/460V power input, it adapts to the harshest installation environments and meets the most stringent operational demands of industrial and mega-commercial applications.

Core Advantages of the KRY-220II Pool Heat Pump

1. Ultra-High Energy Efficiency for Lower Operating Costs

With a market-leading COP of up to 5.1 under rated conditions, this small commercial pool heat pump delivers 70% to 80% energy savings compared to conventional heating methods. Its power consumption is only one-fourth to one-fifth that of a standard electric water heater, making it an ideal solution for year-round commercial pool operations. Though the initial investment is moderate, business clients typically recover full costs within 1 to 3 years through reduced electricity bills, ensuring a fast and reliable return on investment.

2. Comprehensive Safety Protection for Uninterrupted Operation

Engineered for commercial-grade reliability, this unit eliminates the risks associated with open flames, electric leakage, gas explosions, and carbon monoxide poisoning—common hazards of gas or electric heaters. It is equipped with multiple safety features, including overload protection, leakage protection, and high-temperature protection. Fully compliant with stringent commercial safety standards, it significantly minimizes operational risks for facility operators.

3. Intelligent Control for Simplified Facility Management

The energy-efficient pool heat pump supports fully automatic operation, automatically starting and stopping to maintain the set target temperature without unwanted water temperature fluctuations. It offers customizable working modes, including energy-saving mode and fast heating mode. High-end configurations also support Wi-Fi/APP remote monitoring and adjustment, allowing facility managers to oversee and control the unit from anywhere, reducing on-site labor costs and simplifying daily management.

4. Compact, Durable Design for Flexible Installation

Featuring a rugged anti-corrosion structure, IPV4 waterproof rating, and Class I anti-shock protection, the unit is suitable for both indoor and outdoor installation. It operates with noise levels below 50 dB(A), ensuring minimal disturbance to guests in hospitality or residential settings. Its compact dimensions (910×350×835 mm) make it perfect for space-limited installations, offering a key advantage when retrofitting existing pool systems.

Ideal Application Scenarios

Indoor Commercial Pools

Perfect for year-round indoor pools in hotels, gyms, and private clubs, this unit maintains a stable water temperature of 26-30℃ regardless of outdoor weather conditions, ensuring consistent comfort for guests and members.

Outdoor Residential & Small Commercial Pools

Ideal for luxury residential villas, small resorts, and community pools, it provides reliable heating in spring, autumn, and winter, with optional cooling assistance in summer, extending the usable season of outdoor pools by up to 8 months annually.

Professional Constant-Temperature Training Pools

With strong continuous heating capacity, it can quickly restore the set water temperature even during peak occupancy, making it suitable for small professional training pools and water park auxiliary pools.

Installation & Maintenance

The low noise pool heat pump offers fast and non-disruptive installation: small residential pool setups can be completed in 1-2 days, while small commercial pool installations take 3-5 days. The process only requires a brief interruption of the pool’s water circulation system, with no impact on normal pool operation post-installation. Long-term maintenance costs are extremely low: daily upkeep only requires simple flushing of the heat exchanger and filter every 1-2 months, with an annual professional inspection of the compressor and electrical circuits. Annual maintenance costs are significantly lower than those of gas-fired heating systems, reducing long-term operational expenses for business clients.

FAQ About Ultra High Capacity Heat Pump 220kW KRY-220II Industrial Pool

1. How quickly can the KRY-220II heat a large Olympic-size pool from cold?
Heating time depends on initial water temperature and ambient conditions, but the 220kW output typically raises a standard Olympic pool (2.5 million liters) by 1°C every 5–6 hours. For maintaining temperature during normal operation, it easily compensates for heat loss even in open-air or high-occupancy conditions.

2. Does the dual refrigeration circuit provide redundancy?
Exactly. The KRY-220II features two independent refrigeration circuits. If one circuit requires service, the other continues operating at ~50% capacity, so your pool never goes cold. This redundancy is critical for aquatic centers, competition venues, and hotels where downtime is unacceptable.

3. Can I control the unit remotely for multiple pools?
Yes. The KRY-220II includes a smart controller with optional BMS integration (Modbus/RS485). You can monitor and adjust temperature, schedule heating cycles, and receive fault alerts from a central control room or via mobile app. This is ideal for facilities with multiple pools (lap pool, therapy pool, kiddie pool).

4. What electrical supply is required for the KRY-220II?
The unit operates on 380V–460V, three-phase, 50/60Hz. It draws approximately 85–110 kW at full load, depending on ambient conditions.
