Water cooling system for water-cooled machines
For any business with water-cooled equipment. Save water and money: Salvalacqua cools your machines with the same water, over and over.
Stop sending cooling water down the drain
Water-cooled equipment uses water to carry heat away from the condenser: gelato and ice cream machines, pasteurisers, display cabinets, refrigerators, ice makers and other refrigeration in restaurants, hotels, bakeries, butchers, supermarkets and food production. Connected straight to the mains, that is drinking water you pay for, used once and sent to the drain for as long as the machine runs.
Salvalacqua replaces it with a next-generation, closed-loop water cooling system. A chiller cools the water, a pump sends it to your machines and the same water comes back to be cooled again. Precious drinking water is no longer wasted, and no limescale is generated, cutting maintenance costs.
Salvalacqua is made in Italy by BRX Italia and is available in Australia exclusively from Majors Group.

How a closed-loop cooling system saves water and money
Save water
The same water goes round and round. Drinking water used for cooling drops to nothing, and the circuit needs no permanent connection to the water main.
Save money
No more paying for cooling water that goes straight to the drain. The closed-circuit, closed-vessel system needs no topping up, meaning a 100% saving of drinking water used for cooling. It does not require a water softener.
Lower maintenance, faster production
Production equipment works at peak efficiency with cooling at a constant 12–17 °C, for faster ice cream production. No limescale is generated, cutting maintenance costs.
Health protection
The closed circuit completely eliminates the risk of generating the legionella bacterium, which may proliferate in other systems where liquids are in contact with the outside.
Australian case studies: what the figures show
Adelaide Brighton Cement, Angaston SA
Working with SA Water’s Business Water Saver Program, the Angaston plant replaced single-pass water cooling equipment with a closed-loop system and switched its main air compressor and rotary blower to recirculated cooling water. These measures were part of a program that saved about 69,000 kL of water, 23% of the site’s use, between 2006–07 and 2007–08.
O-I Adelaide glass plant, West Croydon SA
In the same SA Water program, O-I Adelaide stopped running drinking water once through its cullet chute and fed the chute from its own recirculation pumps instead. That single change saved about 16,700 kL. Across all its projects the plant cut water use by about 25,000 kL a year.
One machine: up to 300 L an hour
Carpigiani’s spec sheet for the water-cooled LB 502 RTX lists water use of up to 300 L an hour while producing or pasteurising. Run four hours a day, six days a week, that is about 374 kL a year sent to the drain from one machine. Actual use depends on the mix, load, water temperature and settings.
Work out your own saving
Water flow (L/h) × hours a day × days a year ÷ 1,000 gives the kilolitres each machine sends to the drain. Multiply by the water usage price on your bill ($ per kL), plus any trade waste charge. Send us your machine list and we will do the sums with you, then size the right Salvalacqua system.

The case-study savings come from whole-site programs that included closed-loop cooling; they are examples, not a guarantee of savings at your site.
How the water cooling system works: chill, pump, recycle
Salvalacqua is the cooling option for water-cooled refrigeration equipment in any business: batch freezers, pasteurisers, display cabinets, refrigerators and other equipment with a water-cooled condenser.
A sealed loop
A closed-circuit, closed-vessel system containing water, or water and antifreeze. It does not evaporate, never runs out and does not produce limescale.
The chiller
An indoor or outdoor chiller cools the water in the tank of the indoor Salvalacqua unit, keeping it at a constant 12–17 °C.
The inverter pump
The pump with inverter delivers the water from the Salvalacqua unit to your production machines, display cabinets, refrigerators and other equipment with water condensers.
Same water, recycled
Drinking water is no longer used. The same water is constantly recycled, with no need for a permanent connection to the water main.
Water chiller systems: three lines, 15 standard models
Choose by where the heat can go and how much space you have. We help you match the system to the machines you want to connect.
SLQ line
Water cooling system with an outdoor chiller. Two units: an indoor economiser with tank, inverter pump and manual bypass, and an outdoor chiller that releases the heat outside. SLQ V upright and SLQ T bench-height versions.
KUBE line
Water cooling system with an indoor chiller. Two units, both installed indoors. The chiller needs an air inlet and an air outlet to outdoors, through a pipe, flue or window. Only a water connection is required, with no refrigeration connections.
COMPAT line
Water cooling system for small spaces. Storage tank and chiller in a single compact unit. It needs an unobstructed air inlet and vents hot air through a pipe leading outdoors. COMPAT 1, 2 and 3.

Email me the catalogueWater cooling system: frequently asked questions
What is a closed-loop water cooling system?
It is a cooling system for water-cooled refrigeration equipment. Instead of running mains water through the machine and sending it to the drain, a water chiller cools the same water and sends it round again in a closed circuit. Salvalacqua by BRX Italia is this kind of system, also called a water economiser (or economizer).
How does it save money?
You stop paying for drinking water that is used once for cooling and then sent to the drain. The sealed circuit needs no water softener and generates no limescale, so descaling and maintenance costs fall. Cooling at a constant 12–17 °C keeps production machines working at peak efficiency.
Is it worth the investment?
A single water-cooled machine can use up to 300 L of water an hour, so a busy site can send hundreds of kilolitres a year down the drain. In South Australia, sites in SA Water’s Business Water Saver Program that moved cooling to closed loops and recirculated water saved thousands of kilolitres a year. Your payback depends on how many water-cooled machines you run, for how long, and your water and trade waste charges. Call 1800 625 677 and we will work it out with you.
How much water does Salvalacqua save?
The saving of drinking water used for cooling is 100%, because the same water is constantly recycled. The closed circuit does not need topping up and does not need a permanent connection to the water main.
Which machines can be connected to Salvalacqua?
Any equipment with a water-cooled condenser: gelato and ice cream machines such as batch freezers and pasteurisers, display cabinets, refrigerators, ice makers and other water-cooled refrigeration in restaurants, hotels, bakeries, supermarkets and food production. Tell us what you run and we will confirm what can be connected.
Does Salvalacqua need a water softener?
No. The system does not require a water softener. No limescale is generated in the closed circuit, which cuts maintenance costs.
What happens if the chiller needs servicing?
SLQ and KUBE models have a manual bypass as standard. Turning one lever switches your machines to mains water during chiller servicing or a malfunction, so production carries on. An automatic bypass is available as an option.
Which Salvalacqua model do I need?
It depends on the machines you want to connect and the space you have. SLQ uses an outdoor chiller, KUBE keeps both units indoors and COMPAT is a single unit for small spaces. There are 15 standard models from 1,000 to 3,500 litres per hour, plus bespoke solutions for large production. Call 1800 625 677 and we will size it with you.
What power supply does Salvalacqua need?
The standard models are listed for a 400 V, 50 Hz supply. Our team will confirm the electrical and plumbing requirements for your site before you order.
