Overview

The POWERCIAT2 is a high-capacity water chiller range (600 to 1350 kW) designed for environmentally responsible applications with Class A energy efficiency. It integrates advanced technologies to optimize energy consumption, reduce environmental impact, and ensure high performance in commercial and tertiary sector buildings.

Key Specifications and Performance

• Energy Efficiency: Achieves Class A rating with an average EER of 3.15 (HEE version) and an ESEER of 4.1, meeting stringent European environmental and energy standards.
• Versions: Available in Standard (STD) and High Energy Efficiency (HEE) versions to suit different technical and economic requirements.
• Acoustic Performance: Noise levels as low as 60 dB(A) for the 1330 kW model, achieved through silent fans, anti-vibration mounts, sound-absorbing enclosures, and flexible intake couplings.

Innovative Components

• All-Aluminium Micro-Channel Coil: Offers 45% less refrigerant charge, 10% higher efficiency, 20% lighter weight, and 20% smaller footprint compared to traditional copper/aluminium coils. It also facilitates easy maintenance and corrosion resistance.
• Compact Screw Compressors: Latest generation compressors with continuous slide control regulation for precise partial load adjustment, reduced starts, extended service life, and improved energy performance. Equipped with economizers to boost cooling capacity.
• Dry Expansion Shell and Tube Evaporator (COREVA): Patented refrigerant distribution technology enhances heat exchange efficiency, reduces refrigerant quantity, and optimizes pressure drops.

Hydraulic and Control Systems

• Hydraulic Version (LXC): Available with or without buffer tank, factory-fitted hydraulic modules with single or dual pumps including automatic emergency switchover and optional safety sensors for pressure monitoring.
• XtraCONNECT2 Controller: Advanced, user-friendly control system with multi-language backlit display, multiple control modes (water return, supply, climate-based water law, energy storage), and compatibility with major communication protocols (MODBUS, BACNET, LONWORKS).
• Energy Management: Optional energy meter for real-time electrical measurements and consumption limiting, water temperature control based on outdoor conditions, and comprehensive safety features.
• POWER’CONTROL and CRISTO’CONTROL: Smart global management systems for energy pools, enabling optimization of free cooling, energy storage, heat recovery, scheduling, priority management, and remote supervision with BMS integration.

Environmental and Ecodesign Approach

• Reduced Refrigerant Charge: Uses R134a refrigerant with a unique power-to-fluid charge ratio of 7 kW/kg, minimizing environmental impact.
• Heat Recovery Option: Partial heat recovery enables production of domestic hot water at 60°C, ideal for hotels and similar applications, contributing to energy savings and sustainability.
• Lifecycle Considerations: Designed with ecodesign principles to minimize environmental impact across raw material sourcing, manufacturing, transport, use, maintenance, and end-of-life stages.

Product Range and Equipment

• Two main product lines: High Efficiency (HEE) and Standard (STD), with various noise level options (Low Noise, Xtra Low Noise).
• Performance data includes cooling capacity (Cc), power input (Pi), EER/ESEER values, energy class, noise levels, dimensions, and weight for each model.
• Standard and optional equipment includes fused disconnect switches, control transformers, communication interfaces, water flow controllers, electronic expansion valves, star-delta compressor starts, phase controllers, variable speed fans, energy meters, heat recovery, pumps, buffer tanks, remote monitoring, refrigerant leak detection, and more.

Summary of Critical Information

• Energy Efficiency: Class A rating with EER up to 3.24 and ESEER up to 4.22 in HEE versions.
• Environmental Impact: Reduced refrigerant charge, heat recovery capabilities, and ecodesign lifecycle approach.
• Noise Levels: Designed for low acoustic impact, suitable for sensitive environments.
• Control and Integration: Advanced control systems enable optimized operation, energy management, and integration into building management systems.
• Installation and Maintenance: Compact design, lightweight components, factory-tested hydraulic modules, and easy maintenance features reduce installation time and operational risks.

Overall, the POWERCIAT2 water chiller range represents a state-of-the-art solution for high-capacity cooling needs with a strong focus on energy efficiency, environmental responsibility, and operational flexibility.
