Description

Climavaneta NX / CA 0562P High Efficiency Liquid Chiller

Outdoor unit for the production of chilled water including:

  • Hermetic Rotary Scroll Compressors (two compressors in a single-circuit configuration)
  • Ozone-Friendly Refrigerant R410A
  • Axial-Flow Fans
  • Plate Heat Exchanger
  • Aluminium Micro-Channel Air Coils 
  • Electronic Expansion Valve

Class A Efficiency

The full range is available with the class A efficiency rating. Thanks to the generous sizing of the heat exchangers and accurate control of the fan speed, the CA versions grant a premium level of efficiency in every noise configuration.

Aluminium Micro-Channel Heat Exchangers

The NX family uses aluminium micro-channel condenser coils that deliver premium efficiency whilst ensuring a reduced refrigerant volume and a
lower unit weight. The traditional copper/aluminium tube and fin coils are available as an alternative. A full range of protective treatments assures the highest level of resistance to corrosion in any condition, even in the most aggressive atmospheres.

Electronic Expansion Valve Supplied as Standard

The use of the electronic expansion valve generates considerable benefits, especially in cases of variable demand and different external conditions. It has been introduced into these units as a result of accurate design choices concerning the cooling circuit and the optimisation of operation in various different working conditions. The electronic expansion valve comes standard in the high-efficiency CA version.

Wide Operating Range

Full load operation is ensured with outdoor air temperature up to 46°C partial load operation is possible up to or even beyond 50°C. The unit can produce chilled water at negative temperature (down to -10°C of leaving water temperature). Dedicated accessories allow the unit operation down to -20°C of outdoor air temperature.

Integrated Hydronic Module

The optional built-in hydronic module already contains the main water circuit components; it is available with single or twin in-line, for achieving both low or high head.

Unit Standard Composition Structure

Structure specifically designed for outdoor installation. Basement and frame in hot-galvanised shaped sheet steel with a suitable thickness. All parts polyester-powder painted to assure total weather resistance.

Compressors

Compressors are fastened to the unit's frame with anti-vibration mountings, located in a separate compartment from the ventilation section. The soundproofing enclosure of the compartment has a thickness of 30 mm on the sides and on top and 15mm on the bottom. Hermetic scroll compressors in tandem layout complete with oil sump heater, electronic overheating protection with centralised manual reset and a two-pole electric motor.

Plant Side Heat Exchanger

Braze welded AISI 316 plate heat exchanger. The heat exchanger is lined on the outside with 9mm thick closed-cell neoprene lagging to prevent condensation, with a thermal conductivity of 0,33 W/mk at 0°C. The heat exchanger is fitted with a differential pressure switch to monitor the correct flow of water when the unit is operating, thus preventing ice from forming inside; if no flow is detected, the frost protection function is activated using a special heater.

Source Side Heat Exchanger

  • Full-aluminium microchannel coil.
  • Longitudinal V-shaped coil module: Coil structure made with an open-angle Longitudinal V-shaped layout.
  • Horizontal V-shaped coil module: Coil structure made with an open-angle Horizontal V-shaped layout.

Fan Section Source Side

Axial electric fans, protected to IP 54, with external rotor and plastic-coated aluminium blades. Housed in aerodynamic hoods complete with safety grille. Electric motor with built-in overload protection.
Fans diameter: 450m, 800mm or 910 mm according to the unit's size and version. Whilst the electric motor could come with 4 poles, 6 poles or 8 poles according to the unit's size and version.

Continuous adjustment of the fan speed on units: Version CA, sizes 0152P..0262P

Press Static Fan Control

Adjustment of the fan speed with auto-transformer on units: versions SL-CA, sizes 0152P..0812P
