Heatcraft has expanded its HVAC range with two new series of air to water liquid chillers and heat pumps.
The Neosys and Ecolean are technically impressive innovations with an array of features including R410A multi scroll compressors, Owlet variable speed fans and variable water flow, which optimise performance, reduce noise and minimise their carbon footprint.
The Neosys air to water chiller and heat pump offers the options of partial heat recovery and free cooling efficiency.
Partial heat recovery is enabled via installation of additional heat exchangers in the compressor discharge lines. These are designed to recover 15 per cent of the compressors’ rejected heat.
The heat exchangers can supply hot water up to 60°C, which is ideal for heat recovery applications or where large amounts of hot water are consumed, such as clubs, hotels and healthcare facilities.
Further power savings can be gained through the optional Neosys free cooling feature. The unit utilises one or two sets of “V” coils at the rear of the unit for free ambient pre-cooling.
When the ambient temperature falls below the return water temperature by 3°C or more, motorised valves open to allow by-pass return water to flow through the free cooling coils.
The Neosys free cooling function operates as a cooling stage that has a priority on the compressor stages, thus limiting compressor running time and extending the life expectancy of the compressor.
Both the Neosys and Ecolean feature seven-day programming via the Climatic control, which manages power consumption according to use, automatically switching to occupation mode, unoccupied mode or frost free.
Both units can also be seasonally adjusted to offset the water set point, further optimising power consumption.
The Lennox Neosys offers cooling capacities up to 1080kW, and heating capacities up to 509kW, while the smaller Lennox Ecolean offers cooling capacities up to 199kW and heating capacities up to 205kW.
The Neosys and Ecolean series of air to water chiller and heat pumps are available now from Heatcraft Australia.
