AquaSnap®
30RQ

Features

The AquaSnap® heat pump range was designed for commercial applications such as the air conditioning of offices and hotels etc.

This AquaSnap units integrate the latest technological innovations:

• Non-ozone depleting refrigerant R410A
• Scroll compressors
• Low-noise fans
• Auto-adaptive microprocessor control

The AquaSnap units are equipped with a hydronic module integrated into the unit chassis, limiting the installation to straightforward operations like connection of the power supply and the water supply and return piping

Quiet Operation

Compressors:

• Low-noise scroll compressors with low vibration levels
• The compressor assembly is supported by anti-vibration mountings

Air heat exchanger section

• Vertical air heat exchanger coils
• The latest-generation low-noise fans are now even quieter and do not generate intrusive low-frequency noise

Rigid fan installation for reduced start-up noise.

Easy and Fast Installation

Integrated hydronic module:

• High-pressure centrifugal water pump
• Water filter protecting the water pump against circulating debris
• High-capacity membrane expansion tank ensures pressurisation of the water circuit
• Overpressure valve, set to 4 bar
• Pressure gauge to measure the system pressure.
• Automatic purge valve positioned at the highest point of the hydronic module to remove air from the system.
• Thermal insulation and frost protection down to -10°C, using an electric resistance heater and pump cycling.
• Integrated water fill system to ensure correct water pressure (option)

Physical Features

• With its small footprint the unit blends in with any architectural styles.
• The unit is enclosed by easily removable panels, covering all components (except air heat exchanger and fans).

Simplified electrical connections

• A single power supply point (power supply without neutral available as an option and in standard for units size 40kW)
• Main disconnect switch with high trip capacity
• Transformer for safe 24 V control circuit supply included

Fast commissioning

• Systematic factory operation test before shipment
• Quick-test function for step-by-step verification of the instruments, electrical components and motors

Superior reliability

• State-of-the-art concept
• Cooperation with specialist laboratories and use of limit simulation tools (finite element calculations) for the design of the critical components, e.g. motor supports, suction/discharge piping etc.

Auto-adaptive control

• Control algorithm prevents excessive compressor cycling and permits reduction of the water quantity in the hydronic circuit (Carrier patent).

Exceptional endurance tests

• Corrosion resistance tests in salt mist in the laboratory - Accelerated ageing test on components that are submitted to continuous operation: compressor piping, fan supports
• Transport simulation test in the laboratory on a vibrating table.

Options

• Electrical connection
• Hydraulic modules and expansion tank
• Coil Protection
• HLI Communication interface
