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 />

Cond<strong>en</strong>ser<br />
• The <strong>MULTIHAVANE</strong> range includes cond<strong>en</strong>sers of the type<br />
NEOSTAR (L or P) and WA, which are controlled with cascade<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 />
• Liquid line with dryer filter with removable cartridge(s), 3/8” SAE fill<br />
valve with hydroscopic indicator and shut-off valve(s).<br />
Connection valves<br />
• Liquid suction valve and delivery valve according on models.<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 />
190<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 />
• Oil level regulator with float system and a shut-off valve per compressor.<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 />
The electrical <strong>en</strong>closure has double swing doors for easy access<br />
during all interv<strong>en</strong>tions.
