These liquid chillers combine efficiency and performance control with brushless axial fans: they are chillers suitable for achieving average fluid outlet temperatures while optimizing energy use. In standard execution, ambient temperatures up to +40°C are allowed, but set-ups for even higher ambient temperatures can be requested.

RW ax liquid chillers: operation

RW ax systems for industrial refrigeration of process fluids (water, water and glycol) are air-cooled: the only resource used is therefore electrical energy, a decisive advantage in contexts where it is advisable to save water (because of its cost or scarcity).

The IP54-grade machine protection (against dust and other agents) facilitates their installation in outdoor environments, which is also possible at temperatures up to +40°C and above, at the customer’s request.

RW ax liquid chillers from Frigofluid are suitable for achieving average fluid outlet temperatures (between +1°C and 20°C), with excellent control of the resources used for their operation.

Focus: electronic microprocessor of hydraulic circuit and coolant circuit

It is a useful tool for thermostatting water (glycol) and displaying working pressures of refrigerant gas with remote diagnostic capability: an alphanumeric display communicates the operating “status” of the unit. In multi-compressor machines, the microprocessor performs automatic rotation of compressor starts, to balance their working hours, and manages load-dependent partialization.

As with all Frigofluid systems, there is the possibility of remote management from the panel or via serial communication.

Versions and types of accumulation available

RWA ax: internal storage at atmospheric pressure.
RWC ax: internal airtight storage (possibility of connecting other power plants in parallel).
RWE ax: external storage.

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

Industrial Chillers and Dry Coolers for Almag

There is Frigofluid's signature on the refrigeration of Almag's production processes: an opportunity to strengthen relations with a large company in the Brescia area, recognized worldwide. Two industrial chillers and a dry cooler were supplied to the company.

Low-Temperature Industrial Chiller for a Biogas Player

The biomass sector is one of the most interesting for its implications related to energy recovery: Frigofluid supplied an industrial chiller to an international broker, with final installation in Colombia.

Saving Energy with a Turnkey Refrigeration System

A large plastics processing company needed to renew its refrigeration plant in its entirety. During the summer shutdown and the concomitant production stoppage, we built a turnkey refrigeration plant complete with: chillers, adiabatic coolers, heat exchanger, electrical panels and storage tank.

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.
