The effort of RefComp is constantely
addressed to the development of new products and to the wideness of
already existing ranges, in order to offer the most advanced and
ecologically safe technologies, the most complete range for nay kind of
employment, the highest reliability.
RefComp products range includes, besides the complete range of screw
compressors, reciprocating semi-hermetic, hermetic and open compressors,
suitable to work in air-conditioning, industrial processes, in heat pump
cycles and in the employments at avarageand low temperature.
RefComp can supply its customers with one of the widest compressor ranges
available on the market.
Composed of 2,3,4 and 6 cylinders models the P series range s from 1
to 50 Hp (65...155 m^3/h at 50 Hz). The aim of designing a compressor
particularly adapted for operation with non-chlorinated refrigerants (HFC)
has required the adaption of special devices which are normally not
present in the same cooling capacity range. As a result the P series
stands outas an innovative product, characterised by high efficiency and
high reliability. The possibility to customize the compressor with a
considerable list of auxiliaries allows the operation in a wide range of
Distinguishing for the adoption of suction and discharge reed type valves,
the P series comes alonside the L series, giving the operators the
opportunity to choose the most suitable compressor for each aplication.
This way RefComp has chosen once again to be on his customers'side.
The L series is composed of 9 models in semi-hermetic reciprocating
version with capacities from 25 to 80 Hp (76:::240m^3/h at 50 Hz). The
adoption of ring suction and discharge valves, together with particular
technical solutions coming directly from industrial type compressors
(replaceable cylinders sleeves, electric motor fixed with a key-and-screw
device), distinguishes the L series in the landscape of small and medium
size refrigerating compressors.
Moreover, the 6 and 8 cylinders models (L160, L180, L190, L210) are
equipped with particular devices which reduce to a minimum the oil
carryover in the refrigerating circuit: "Venturi" depressor
system, crankshaft seal, chromium-plated piston rings.
The F series is composed of 4 models in semi-hermetic reciprocating
version with capacities from 60 to 100 Hp (203...325 m^3/H at 50 Hz).
Years of operation all over the world with a range of extremely severe
applications, both in the industrial and marine fields, give reason to the
continuous commercial success of the F series. A compressor which has its
winning features in the industrial design (replaceable cylinder sleeves,
electric motor fixed with a key-and-screw device, hydraulic capacity
regulation) and in the extremely easy maintenance and service operations.
The OF series is composed of 4 models in reciprocating open version
with displacements from 203 to 325 m^3/h. The compressors can be directly
connected to an endothermic or electric motor by coupling. The direct
origin from the semi-hermetic F series (replaceable cylinder sleeves,
hydraulic capacity control, easy maintenance and service), justifies the
widespread appreciation and the continuous success of this products in the
most different industrial applications and, most of all, in the marine
applications where more than elsewhere the reliability is a key
The M series is composed of 3 models in semi-hermetic reciprocating
version with displacements from 348 to 464 M^3/h. Designed with an
industrial logic (replaceable cylinder sleeves, electric motor fixed with
a key-and-screw device, hydraulic capacity regulation, motor protection
filter net) the M series situates in the market of big size reciprocating
compressors as ideal substitute to a fractionated compressor unit,
achieving an extremely competitive relation between cost and cooling
capacity. Besides, the use of particular technical solutions allows an
elevate compression efficiency also in part load operation.
Composed of 10 screw compressors in semi-hermetic compact execution
RefComp S series ranges from 150 to 482 m^3/h. The use of a directly
flanged on high efficiency oil separator simplifies the installation of
the compressor in machine, making it absolutely similar to that of a
common semi-hermetic reciprocating compressor. The hydraulic slide valve
capacity control system (3 steps, operation at 100-75-50-25%), allows
particularly high compression efficiency also in part load operation. As
an option, the compressors can be also delivered together with a
continuous capacity control system (25...100%) which allows a continuous
adaptation of the cooling capacity to the thermal load, with a
consequential energy saving.
Including 10 screw compressors in semi-hermetic execution with
external oil separator, the W series ranges from 30 to 90 Hp. Each
compressor size (118, 150, 175, 205, 237 m^3/h @ 50 Hz) is available with
two different intrinsic volumetric ratios (Vi) optimised either for low
and medium/high evaporating temperature. The user has therefore the
possibility of choosing the ideal compressor depending on the particular
application. As a consequence, the maximum compression efficiency is
always performed. The use of an external oil separator leads to the
highest flexibility in the designing of racks with a number of compressors
variable from 2 to 6 with one common oil separator (parallel compounding).
Beside this, the oil cooling widens the application limits up to the
hardest operating conditions. A complete series of accessories for the oil
return line (between the oil separator and the compressor) is provided in
the standard delivery. Furthermore, a complete range of oil separators and
oil coolers is also available. The low vibrations level and the absence of
discharge gas pulsation make the use of anti-vibrating dampers and
flexible pipes not necessary. In addition, the extremely low noise level,
concentrated in the medium-high frequency range, is very easy to insulate
The W series compressors feature an oil–injected helical twin screw
design; the male rotor is directly connected to the electrical motor (2
poles, 3000 rpm) and drives in turn the female rotor. The perfect rolling
behaviour leads to an extremely smooth running. The innovative design of
rotors profile (5 lobes male rotor, 6 flutes female), the high quality
production standard and the use of superior quality mechanical components
lead to high compression efficiency, high reliability and long operating
life. The hydraulic slide valve capacity control leads to a high
compression efficiency during part load operation. This makes the W series
particularly suitable for applications where long periods of part load
operation are required. The use of the subcooling economiser circuit (ECO)
leads to a further increase in the cycle efficiency (COP).
