Composition of models<br />

• Select for each model:<br />

The compressor technology,<br />

- OCT (Octagon semi-hermetic piston),<br />

- or Sc (Scroll),<br />

- or SH (Semi-Hermetic piston).<br />

The noise level,<br />

- standard<br />

- or LN (low noise) suitable wh<strong>en</strong> noise is a problem (noise isolation of the<br />

compressor compartm<strong>en</strong>t and cond<strong>en</strong>ser with up to 16 fans).<br />

The cond<strong>en</strong>ser,<br />

- standard<br />

- or S (oversized) for high ambi<strong>en</strong>t temperatures.<br />

shutdown.<br />

Receiver<br />

• Horizontal liquid receiver with 2 inlet/outlet shutoff valves.<br />

• Single or double safety valve with 3-way valve if the capacity<br />

is > or = to 100 l.<br />

Liquid line<br />

Control and safety<br />

• The unit is controlled as follows:<br />

- For units with 2 Scroll or Octagon compressors: Pressure control<br />

with 1 LP pressure switch per compressor and 1 control HP<br />

pressure switch per cond<strong>en</strong>ser fan.<br />

- For the other units: Electronic control with LP/HP s<strong>en</strong>sors delivering<br />

a 4/20mA signal<br />

• A g<strong>en</strong>eral safety LP pressure switch.<br />

• One oil differ<strong>en</strong>tial pressure switch per compressor (only for semihermetic<br />

compressors and from compressor 4VC for OCT).<br />

• 1 or 2 automatic reset HP pressure switch(s) per compressor.<br />

(compliant with standard EN 378-2: 2009) 2009)<br />

• Two manometers (LP+HP).<br />

• Connection of each elem<strong>en</strong>t with 1/4" flexible hose.<br />

Switching <strong>en</strong>closure<br />

• Switching <strong>en</strong>closure with double swing doors and latching system.<br />

• Main isolator switch on front panel with “Power on” indicator.<br />

• All electrical compon<strong>en</strong>ts are connected to a board containing the<br />

cond<strong>en</strong>sing unit protection and control elem<strong>en</strong>ts.<br />

Description<br />

Frame / Casing<br />

• The frame base is made of folded, high resistance, galvanized sheet metal.<br />

• The casing is composed of RAL 9002 painted sheet metal.<br />

• The casing panels may be easily removed with the ¼-turn latches.<br />

• The base frame is equipped with lifting rings for easy handling.<br />

Compressors<br />

• The compressors are filled with R404A ester oil and equipped as indicated<br />

in the table below:<br />

Oil pump From 4VC No Yes<br />

Head fan Low temp. range No Low temp. range<br />

Collectors<br />

• The suction and delivery collectors are made of stainless steel 304L for SH and<br />

copper for Sc and OCT, secured with polypropyl<strong>en</strong>e straps on the suction side<br />

and high temperature resistant polyamide straps on the delivery side.<br />

• A g<strong>en</strong>eral filter unit is used on the suction side or one per compressor according<br />

to model with removable cartridge(s).<br />

Oil line<br />

• LP oil return with removable oil separator and tank equipped with high/low level<br />

indicator, shut-off valve and calibrated degassing valve in the LP collector with<br />

shut-off valve.<br />

Advantages<br />

Installation<br />

Cond<strong>en</strong>sing units delivered ready for installation with factory<br />

pre-wired switching <strong>en</strong>closure to help reduce installation time.<br />

The base frame is equipped with lifting rings for easy handling.<br />

Oversized cond<strong>en</strong>ser for the AS model for installation in zones<br />

with high ambi<strong>en</strong>t temperatures.<br />

The low noise ALN model is ideal for use in an urban <strong>en</strong>vironm<strong>en</strong>t.<br />

Servicing / Maint<strong>en</strong>ance<br />

The side panels may be simply removed with 1/4 turn latches<br />

offering easy access to all compon<strong>en</strong>ts.<br />
