Features

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

Environmental care

PUREtec™ R-1234ze long-term refrigerant solution Leak-tight refrigerant circuit

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

Control / Integrations

Integrated Heat Machine Control

Built‑in control system manages:
Heating capacity
