GENERAL CHARACTERISTICS
FRIGO SCREW WP: Packaged heat pump water/water liquid chiller for chilled water production in
summer time and hot water production in winter time (inversion on hydraulic circuit at Customer
care).
The machines are made for indoor installation.
Framework with sections of thick steel for high resistance to the greatest stress during handling and
transport.
Machines supply fully assembled with refrigerant charge and control systems. The installation
requires only electrical and hydraulic connections allowing costs and time savings.
Final assembly on all machines before shipment including running test, reading and monitoring of
operating parameters, alarms simulation and visual check.
Design, assembly and test as per the Company Quality Assurance program in full compliance with
ISO 9001:2008. RC Group has been the first Italian company in its segment to get the Company
th
Quality Assurance in October 13 , 1991 with certificate ICIM 0018.
Environmental Management System Certification according to ISO 14001:2004.
The machines are in full compliance with European Directive 2006/42CE, 2006/95CE,
2004/108CE, 97/23CE and subsequent amendments

OPTIONAL ACCESSORIES – “BRINE A” KIT
The accessory allows the production of glycol solution leaving the machine down to a
temperature of -6°C.
The kit includes:
Set of the working parameters.
Compressor oil cooling system through liquid injection.
OPTIONAL ACCESSORIES – “BRINE B” KIT
The accessory allows the production of glycol solution leaving the machine lower than –6°C.
The kit includes:
Set of the working parameters.
Evaporator in special execution for low temperature.
Special thermal insulation of the evaporator.
Compressor oil cooling system with welded plate heat exchangers oil / refrigerant
liquid.
WARNING:
With BRINE Kit it is mandatory to use antifreeze mixture. Refer to the paragraph
ANTIFREEZE SOLUTION.
The use of antifreeze mixtures causes a reduction of the machine performance,
Please refer to the RC WORLD electronic catalogue to obtain the effective performance.

OPTIONAL ACCESSORIES - PARTIAL HEAT RECOVERY SYSTEM
The partial heat recovery exchangers are installed on every refrigerant circuit of the machine
before the main condenser.
The system is not regulated and the control is ON-OFF type. The heat recovery system’s
operation is subject to the supply demand of cooling capacity.
The system includes:
Copper brazed plate type heat exchanger with cover plates, plates and connections in
AISI 316 stainless steel.
Anticondensate insulation made of polyurethane.
The heating capacity which is supplied depends on the kind of refrigerant gas which is used and
working temperatures.
The heat exchangers can produce hot water up to the maximum temperature of 70°C and
according to the working conditions of the unit.
