GUG-01/02/03SL-E – Lossnay Air Processing DX Unit

Mitsubishi Electric Air Conditioning - Lossnay GUG DX Coil

Enquire Now

The Lossnay GUG-01/02/03SL-E Air Processing DX Unit works in conjunction with a Mr Slim outdoor unit to heat and cool the supply air from a Lossnay Mechanical Ventilation Heat Recovery (MVHR) unit.

The combination of these three products effectively creates an air handling system that can supply temperature controlled clean fresh air in a highly efficient manner.

Key Features:

  • Provides heat recovery ventilation and air conditioning from the same ventilation system
  • Air flow range from 500m3/hr. to 2500m3/hr
  • Single system reduces installation time, costs and space
  • Can be operated in supply air or return air control
  • Built in drain pump to facilitate easy installation
  • Single remote controller provides basic functions. PZ-61DR-E can be added for full functionality
  • Available in 3 sizes, 01, 02 & 03

1. The running current and input power are based on 230V/50Hz. 2. The cooling and heating capacities are based on the air conditions listed below and the rated airflow of fan speed 4. Cooling Indoor: 27°CDB/19°CWB Outdoor: 35°CDB/24°CWB Heating Indoor: 20°CDB/15°CWB Outdoor: 7°CDB/6°CWB 3. The first figure in ( ) of the capacity specification is the heat recovery energy of the Lossnay unit. The second figure is the capacity specification for the Dx-coil connected to the outdoor unit. 4. ”Performance index” is the calculated value at the temperature conditions above and is reference purpose only. Performance index = Total capacity ÷ total power consumption of outdoor unit and Lossnay unit 5. The external static pressure listed above includes the static pressure loss of the Dx-coil unit when using a 50cm straight duct between the Lossnay and Dx-coil units. When the duct work between the Lossnay and Dx-coil units is longer and/or bent, the pressure loss of the duct work should be included in the pressure loss calculation. 6. The designed airflow of the system (Lossnay, Dx-coil and duct work) at fan speed 3 and
4 should be kept within “Airflow range at SP3 and SP4” listed above. This range is shown as the green line in graphs of the characteristics curve. If the Lossnay airflow is out of this range, the compressor of the outdoor unit may stop for self-protection purposes. 7. By installing the Dx-coil unit with a Lossnay unit, the air blow noise level is quieter at fan speed 4 as shown below. LGH-150,200RVX-E: about 3dB quieter. 8. Refrigerant leakage contributes to climate change. Refrigerant with lower global warming potential (GWP) would contribute less to global warming than a refrigerant with higher GWP, if leaked to the atmosphere. This appliance contains a refrigerant fluid with a GWP equal to 1975. This means that if 1kg of this refrigerant fluid would be leaked to the atmosphere, the impact on global warming would be 1975 times higher than 1kg of CO2, over a period of 100 years. Never try to interfere with the refrigerant circuit yourself or disassemble the product yourself and always ask a professional.
