- OFFICINE MARIO DORIN S.P.A.
- product brand:DORIN
- Numéro de stand：E2D47
- product specification:
- product category:Refrigeration Equipment-Refrigeration systems and plants-Chillers, liquid
- product introduction:Compressors belonging to HEX range are
designed according to the safety requirements
imposed for the use in flammable risky areas
(zone 2, gas group IIB), as defined in ATEX
2014/34/EU, with electric component conforming
to such directive (exception made for INT69 and
CPM3).
The range covers displacements from 4,42 to
244,78 m3/h and nominal capacities from 0.5 to
90 hp.
The main characteristics of our compressors are:
• high C.O.P. values, thanks to fluidodynamic
optimization of the internal flow paths, to high
efficiency motors and high tech components
• suitable for all the main refrigerants available:
HC (R290 and R1270) and HFC (R404A, R134a,
R407C, R507, R407F, R407A, R448A, R449A,
R450A, R513A, R452A)
• very low noise level
• available on request for frequency variations
• standard electrical box IP65
• PTC sensor for discharge temperature control
standard for the entire range
• special oil sight glass
• PAG oil for HC (R290 and R1270) and POE for
HFC (R404A, R134a, R407C, R507, R407F,
R407A, R448A, R449A, R450A, R513A, R452A)
• special heads for ranges HEX11, HEX2,
HEX32, HEX34 and HEX41
• Special oil differential pressure sensor (standard
for HEX5, HEX6 and HEX7) and crankcase
heater (standard for entire range), category 3G,
protection rating Ex nA
• special accessories, category 3G, protection
rating Ex nA applying to crankcase heater, coils
for capacity regulation and unloaded start.
Each compressor shows following ATEX
marking:II = group II machinery
3 = category 3 (zone 2)
G = explosive atmosphere with gas, vapor or fog
presence
c = protection type for non-electric equipment
(constructive safety)
Ex nA = protection mode non-sparking “nA”
IIB = group of gas
T3 = class of temperature (gas)
It is mandatory to carefully read instruction manual
before compressor installation .
This catalogue displays only calculated
performance and application envelopes for HC
refrigerants, propane (R290) and propylene
(R1270).
For HFC performance, please refer to H range
compressor catalogue.

each model, refer to Dorin selection software.
Dorin’s manufacturing quality is granted by the
certification provided in accordance with Directive
EN ISO9001.
