AquaForce® 61XWHZE – High temperature water-sourced heat pump using HFO R-1234ze refrigerant

Renewable heat solution

• Perfect solution for district heating systems
  • Possibility to combine multiple 61XWHZE heat pumps to reach the best efficiency and higher capacities
  • Eligible for financial incentives in many countries
• Perfect solution for smart cities
• Perfect solution for process heating and facilities space heating

Low energy consumption

• Renewable energy source to comply with EU 2020 targets (27% of renewable energy)
• No need for a gas network
• Heat pump technology is more efficient and sustainable than any fossil fuel combustion system
• Great Coefficient Of Performance (COP of 6 or more), with very low carbon impact when compared with traditional boilers
• The high energy efficiency is reached through twin rotor screw carrier compressor, equipped with a high-efficiency motor and a variable capacity valve that permits exact matching of the heating capacity to the load
• Flooded multi-pipe heat exchangers for increased heat exchange efficiency
• Electronic expansion device permitting improved utilization of the evaporator heat exchange surface
• Economizer system

Low sound level

• Silencers on the compressors discharge line
• Silencers on the economizer return line
• Acoustic insulation on the components that are most subjected to radiated noise
• Specific attenuation possible upon request

Easy and fast installation

• Just need an electrical connection and a water source
• Compact design
• Simplified electrical connections
• Simplified hydraulic connections
• Fast commissioning

High reliability and easy servicing

• Increased global performance as well as Carrier’s acclaimed product quality and reliability
• Major components are selected and tested with R-1234ze refrigerant to minimize failures possibility, as well as many design choices have been taken in this perspective
• Industrial-type screw compressors with oversize bearings and motor cooled by suction gas
• Compressor components easily accessible on site minimizing down-time
• One or two independent refrigerant circuits, the second automatically takes over if the first one develops a fault
• Electronic paddle-free flow switch. Auto-setting according to cooler size and fluide type
• Auto-adaptive control
• Exceptional endurance tests

Safe design Carrier

• Specific compressor gaskets compatible with HFO-1234ze, tested and validated
• New relief valves designed for operation with HFO-1234ze and high temperature
• Specific electrical box with increased tightness and integrated blower that maintains positive air pressure to avoid any risk of ignition
• New control algorithms

06T twin-rotor screw compressor

• Equipped with bearings with oversized rollers, oil pressure lubricated for reliable and durable operation, even at maximum load
• Optimal adjustment of the compressor cooling capacity
• If a fault occurs, the compressor does not switch off, but continues operation with a reduced capacity (unloaded mode)
• The silencer in the discharge line considerably reduces discharge gas pulsations for much quieter operation
• Condenser includes an oil separator that minimizes the amount of oil in circulation in the refrigerant circuit and redirects it to the compressor function
