S-ASX-LQ Commercial High Temp Air-to -Water Heat Pump (55 – 95kW)
The S-ASX-LQ range comprises 5 models offering LTHW heating in 55,65,75,85 and 95kW outputs in the A7W35 condition.
All the units are capable of generating up to 68°C flow temperature utilising the built-in liquid injection flow temperature booster (LQ).
Note: This will depend on the model, the units achieve a COP of between 4.45 and 4.51 at 7°C ambient air temperature and 35°C flow temperature.
The control system allows the unit(s) to be operated in cascades of up to 16 units.
The units of are monbloc design suitable for outside installation and are supplied as standard with a built-in modulating pump, low noise set up and soft start compressor.
Heat energy from the ambient air is obtained from the R410A refrigerant circulating inside a bank of copper and aluminium fins and
then this energy is passed, after the compression cycle, to the heating circuit through a stainless steel brazed heat exchanger.
The circuit is controlled by the standard supplied temperature probes and pressure transducers and is protected by high and low pressure switches.
The plate heat exchanger and all hydraulic pipework is thermally insulated to avoid condensation and avoid heat loss.
The S-ASX-LQ units are fully reversible and can operate in cooling mode in the summer months achieving EER of 3.80 at 35°C ambient air and 18°C flow.
