LIEBERT® HPA

CONDENSER

HIGH PERFORMANCE CONDENSERS, 5-100 KW COOLING CAPACITY

Liebert HPA of Emerson Network Power dissipate the heat coming from air cooled direct expansion indoor units. Specifically designed for High Performance Air Conditioning (HPAC) applications, Liebert HPA are characterised by high energy efficiency, excellent reliability and low sound emissions.

Liebert HPA condensers are air-cooled outdoor units available in a wide range of sizes, from 5-100 kW cooling capacity. They fulfill every demand, from small switchboards to the big computer rooms, including working environments such as offices, museums and trading rooms.

Features:

• Safety switch
• Power supply 50 Hz or 60 Hz
• Pipe adapters
• Modulating fan speed control. Silent function during the night.
• Service valves with pressure tap
• Silent axial fans. IP54 motors.
• Legs can be used either for horizontal or vertical installation.

Benefits:

• Suitable for R410A refrigerant
• Two versions available: single (HCE models) and double circuit (HBE models)
• All the models have coated aluminium frames. The standard coil is made of copper piping and aluminium fins. There is also the option of epoxy coated coils or copper fins, for better resistance to corrosion.
• The inner surface of the pipes has a special pattern that, through increased turbulence, allows greater heat exchange at the same airflow.
• The fans consume less energy and produce less noise.
• Thanks to special coil supports, there is no contact between the pipes and the frame. This eliminates the risk of breaking the sealed circuit thus improving the durability of the product.

HIGHLY EFFICIENT, RELIABLE HEAT PERFORMANCE DRY COOLER

Liebert HPD of Emerson Network Power dissipate the heat coming from water-cooled direct expansion indoor units. Specifically designed for High Performance Air Conditioning (HPAC) applications, Liebert HPD outdoor units can operate with water or glycol mixture up to a 40% concentration.

If connected to Liebert indoor FREECOOLER units, they can use low temperature outside environments to cool the room without using the compressors. Resulting energy savings can be up to 30% per year.

Features:

• Modulating fan speed control with single set point
• Modulating fan speed control with double set point for free cooling operation, to switch between summer mode (compressor working) to winter mode (free cooling operation)
• Epoxy-coated coil
• Hydraulic connections flange kits (for three-phase models, single-phase models are provided with threaded hydraulic connections)
• Can be installed either horizontally or vertically, with simple operation to be done on site

Benefits:

• Equipped with heat exchangers made with oval copper tubes
• Design improves the heat exchanger capacity versus drycoolers with traditional coil geometries

The Liebert® MC microchannel condenser is designed to match the outstanding performances of Liebert PDX and Liebert CRV direct expansion units.

The highly efficient Liebert MC unit directly communicates with the indoor units via the integrated iCOM^TM Control, providing significant advantages in terms of condenser management. The Liebert MC can thus be managed through the Liebert PDX or Liebert CRV iCOM Control, consequently allowing the complete coordination of the unit and condenser settings status and alarm conditions.

The possibility of selecting silent functioning modes at defined times (i.e. during the night or the weekend), through the unit control, further ensures full operating flexibility.

Features:

• Microchannel Condensing Coil – The full aluminum coil ensures enhanced efficiency levels also during the mechanical cooling mode.
• New Generation EC Fans – The new generation EC Fans guarantee the highest efficiency at full and at partial load, ensuring also extremely silent operation.

Benefits:

• Equipped with EC Fans that require a lower power input, thus reducing energy consumption and guaranteeing top-tier performances
• Full operating flexibility ensured by the iCOM^TM Control
• 20% increase in unit efficiency at full load
