The RW CW line was developed to serve production islands where air movement is not permitted. Electronic control also allows the energy used by these liquid chillers to be optimised. Low temperatures, efficiency, protection from external agents.

Low fluid outlet temperatures. Down to -8°C, even with average outside temperatures.

Optimising efficiency and energy. Thanks to the electronic control enabled by EC Brushless axial fans.

Splash and dust resistance. The IP54 machine protection is especially useful for outdoor installation.

Turnkey solution. A single point of contact throughout the project, possibility of integration with further systems and ancillary plant components.

Quick pay-back. Pre-selection together with the customer, based on his project requirement.

Ready for remote monitoring. A serial port can be coupled to the machine for interface connection with a remote station.

Liquid chillers for low temperatures, also in outdoor environments

The RW CW series of process fluid coolers (water, water/antifreeze) are water-cooled and operate with environmentally friendly gas compression. They allow cooled liquid temperatures between -8°C and +20°C.

In standard design, ambient temperatures of up to +40°C are permissible, but in the “RW ax/HTA” version even higher ambient temperatures can be achieved. IP54 degree of protection as standard, allowing outdoor installation without a protective roof.

Series components on all Frigofluid chillers

EC (electronic control) Axial Fans

As standard over the entire production range. They guarantee high performance at top speed and control in the slowrunning range.

Microchannel Condenser

Featuring a wide exchange surface and subcooling system plus epoxy paint surface treatment as standard.

Compressors

Hermetic systems of “Scroll” type on all models in the catalog.

AISI 316 SS Plate Evaporator

Or tube-nest evaporator. With foam closecell thermal insulation.

Storage tank

In zinc-plated steel featuring close-cell foam insulation and a range of accessories: air exhaust, safety valve, discharge valve, fittings for level control.

Electronic Microprocessor of Industrial Chillers

Electronic Microprocessor for the hydraulic and Chilling Systems

Allowing control of the (glycol-added) water temperature and display of the chilling gas operating pressure with remote diagnostics possibility: an alpha-numeric display shows the unit’s working status. In the units with more than one compressor, the microprocessor controls their starts on a rotation basis in order to balance their operating hours.

Manual By-Pass

An accessory designed for the function of adjusting the flow rate of water or water/glycol from a hydraulic circuit so as to obtain a working condition suitable for the chiller and its use. This adjustment is carried out by controlling the discharge pressure of the chiller pump.

Expansion Vessel for Industrial Chillers

Expansion Vessel Kit

An accessory designed for the function of containing changes in "hydrostatic" pressure in a type "C" (pressurized) hydraulic circuit due to changes in water and/or water/glycol liquid temperature.

Outdoor Kit

This is an accessory consisting of 3 elements that ensure IP 55 watertightness of the electrical panel and its components for outdoor installation without any canopy or other protection. With OPT 01250 a cover is applied on the electrical box that protects the gasket of the switchboard door.

RTU Modbus

Allows communication of data from our control panels with supervisory and/or other systems through a modbus communication but also OPC UA and PROFINET.

Automatic Loading

Hydraulic system aimed at controlling the filling from water or water/glycol of hydraulic circuits. Consisting of accessories and fittings, it is installed on RW power plants, RAW coolers, and systems in general.

Water Filter

Mechanical filter installed on the water inlet pipe to the chiller (return). The filter usually Y-type can be bronze for sections up to 2" ½ max 3", or spheroidal cast iron flanged for sections 3" and up.

Some Frigofluid projects

Water Chiller and Compressors for Energy Efficiency

Our partner, an Italian energy efficiency contractor, needed to modernise the production processes of a food products company: Frigofluid selected a water chiller and three compressors.

Custom Chiller for a Machinery Manufacturer

Frigofluid is also available for highly customized chillers: this is what a food industry machinery manufacturer also required for a chiller solution capable of working in outdoor environments and with fluid output at temperatures below 0°C.

Water-Cooled Industrial Chiller for Oil & Gas Plants

Per un player dell'oil & gas, Frigofluid ha selezionato un refrigeratore industriale condensato ad acqua ad alta efficienza.

Preliminary Assessment

Many interlocutors come to us with a very general idea of their industrial refrigeration needs: this is normal. That's why we stimulate the sharing of technical information.

Customized Design

We believe that integration with the best accessories on the market and the careful and 'unified' selection of internal components can make the difference.

Custom Chillers and Turnkey Plants

Production facilities and the characteristic of the installation area also have important effects on the design: because one cannot stop at the listed solutions.
