DIMPLEX HEAT PUMPS Air Source Heat Pumps

LA TU Range

• High efficiency air source heat pumps for high capacity heating systems, for outdoor installation.
• Model range:
  LA 9 TU – 9kW, three phase
  LA 12 TU – 12kW, three phase
  LA 17 TU – 17kW, three phase
  LA 25 TU – 25kW, three phase
  LA 40 TU– 40kW, three phase
• CoP 4.4 (heat output and coefficient of performance data measured at operating condition A7/W35, based on LA 40 TU)
• High COPs, even at low ambient air temperatures, due to higher performance evaporator.
• Installed outdoors, so minimal indoor space required.
• Variable heating water flow temperatures from 35ºC to 58ºC, weather compensated.
• Twin compressors (models 17kW and over) for higher capacity output and two performance capability.
• Intelligent load switching between compressors to maximise compressor life.
• Suitable for use with underfloor heating, radiator systems and to provide domestic hot water.
• Operational temperatures from +35ºC to -25ºC.
• Corrosion resistant stainless steel inner frame and powder coated outer housings.
• Sound-optimised through electronically controlled, low-speed axial-flow fan with low, natural-sounding accoustics and insulated, decoupled compressor housing.
• Side or under-unit entry for hydraulic/electrical connections.
• Supplied complete with wall mounted WPM EconPlus heat pump manager and integrated heat meter.
• Multiple units can be connected in parallel using master heat pump controller*.
• Energy optimised auto adaptive defrost cycle.
• Scroll compressor providing efficient, low noise running.
• Three phase electrical connection with electronic soft start to reduce starting current loads.
• Option of flexible expansion for:
  Bivalent or bivalent-renewable operating mode.
  Distribution systems with mixed and unmixed heating circuits.
