The 61WG units are new Carrier chillers and heat pumps designed for commercial offices.
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.
