1 - INTRODUCTION

HYDROCIAT

 water-cooled condensation chilled water 

production units, with 

LW series

 screw compressors, and 

LWP series

 heat pump, provide the perfect solution to the 

problems encountered in the fields of air conditioning or the 
industrial process.
These units comply with standards EN 60-204 and EN 378-2, 
as well as the following directives:
- Machinery 2006/42 CE
- EMC 2004/108 EC
- LVD 2006/95 EC
- PED 97/23 EC
->  Category 3 models LW - LWP 1800BX (HPS) to 2800BX (HPS)
->  Category 4 models LW - LWP 3050BX (HPS) to 4800BX (HPS)

Test pressure (TP): 

Test not executed given the 

harmfulness of a hydrostatic pressure test. CIAT has set up 
compensatory measures (tests on a model representative 
of all 3 x PS assemblies) in compliance with § 5.3.2.2 a and 
6.3.3 iii of standard 378-2.

Shipment temperature:

LW 1800 to 2800 →  Min. -30°C - Max. 50°C.
