Features
• Eleven sizes with nominal heating capacities from 29 to 117 kW.
• Aquasnap heat pumps designed for commercial (offices, hotels etc.), residential
(houses, apartments etc.) or industrial applications (domestic hot-water production
etc.).
• Optimised for heating applications - leaving water temperature up to 65°C (without
auxiliary heating), evaporator temperature down to -5°C and a COP of above 5.
• Units are equipped with the latest generation R-410A scroll compressor,
optimised for high-performance.
• Large number of options: hydronic kits with or without variable water flow rate,
reinforced sound insulation, stacking and connection of two units, or operation
with low-temperature glycol solution down to -12°C. Unique combination of
high performance and functionality in an exceptionally compact chassis.
• The high temperature makes these units compatible with most heat sources,
both in new and refurbished buildings and permits domestic hot water
production in significant quantities (dual setpoint).
• Units use weather compensation control and control four supplementary
electric heating stages or a relief boiler.
• Complete hydronic kit for both evaporator and condenser with different levels of
available pressure, with variable or fixed speed.
• Needle valve control for easier transition from the comfort mode to domestic
hot water production using a collection tank (not supplied).
• Reversibility by water flow inversion in the system.
• Pro-Dialog+ control and compatibility with the Aquasmart system
• Units available with connections at the top or at the rear.
• Easy installation: small footprint, ideal for refurbished buildings, allows access
in very tight plant rooms.
• The variable water flow (VWF) technology of the variable-flow pump, optimises
system operation and enhances energy efficiency.
• Standard low sound level allows installation in any building type.
