Indoor motor-driven evaporating units LER 0-0 kw Compact and silent machines with remote dissipation into the air Scroll compressor PLUS R-0A R-0A refrigerant Cooling only Split version Electronic

1 Indoor motor-driven evaporating units LER 0-0 kw Compact and silent machines with remote dissipation into the air Scroll compressor PLUS R-0A R-0A refrigerant Cooling only Split version Electronic expansion valve Up to compressors or cooling circuits Remote connectivity with the most common protocols Compact dimensions Low noise levels due to the panelling The LER range consists of 9 models with a cooling capacity range from 0 to 0 kw and is available in a standard or silenced acoustic version. The possibility of setting up different cooling circuits in units of the same power means being able to personalise efficiency levels under full or part load conditions and the redundancy. Three different efficiency packs are available: cooling circuit, compressors cooling circuits, compressors cooling circuits, compressors The LER units are developed in a completely enclosed version for a low noise operation making it possible to install them in non-segregated environments. They are characterized by a rounded shape contributing to an attractive appearance. The possibility of keeping the evaporator indoors means there is no need to add glycol to the water inside the system, which brings clear benefits in terms of thermodynamic efficiency, protection against corrosion and respect for the environment. In addition, you can keep all components requiring maintenance in an easily accessible room. In air-conditioning applications it is often requested to have heat available for heating sanitary water or controlling post-heating in air-handling units where independent temperature and humidity control is required. all the cooling only units of the LER series are available on request with desuperheater for partial heat recovery; the available thermal power, which can, for example, be used to produce domestic hot water or for post-heating heat exchangers, depends on the unit s operating conditions. The LER units and the remote heat sink are connected with refrigerant lines whose length can exceed the conventional limits by using a specific kit for oil recovery and creating siphons distributed on the lines. galletti.com VM000-C

LER 0-0 kw MAIN COMPONENTS Structure Scroll compressors Heat exchanger Made in galvanised steel sheet with a polyester powder coating for outdoors.

Scroll compressors are now the best solution in terms of reliability and sound power emitted.

2 LER 0-0 kw MAIN COMPONENTS Structure Scroll compressors Heat exchanger Made in galvanised steel sheet with a polyester powder coating for outdoors. The compressor compartment is completely sealed and may be accessed on sides thanks to easy-to-remove panels that greatly simplify maintenance and/or inspection. Scroll compressors are now the best solution in terms of reliability and sound power emitted. The compressors are supplied complete with motor protection against overheating, overcurrents and excessive outlet gas temperatures. Heat exchangers with braze-welded AISI austenitic stainless steel plates and connections made of AISI L, characterised by a reduced carbon content to facilitate brazing. Cooling circuit It can be made in three different versions with the same power (Efficiency Pack), using mainly: R0A scroll compressors braze-welded plate exchangers electronic expansion valves Electronic microprocessor controller It allows complete management of the unit. The electronic control system allows the setpoint to be adjusted automatically according to the outdoor temperature in order to reduce consumption and broaden the working temperature range. With the advanced microprocessor control it is possible to set up LAN networks for controlling units in parallel. CONFIGURATION The models are completely configurable by selecting the version and the options. To the right is shown an example of configuration.
