With rising costs continuing to challenge dairy farmers, improving energy efficiency on farm has become an important priority.

Electricity used for milk cooling and storage is one of the largest energy demands in the dairy.

On average:

Milk cooling accounts for approximately 30-40% of total electricity consumption on dairy farms, making it one of the largest daily expenses behind the scenes.

Choosing a modern, efficient milk tank can play a significant role in reducing running costs while ensuring milk quality is protected.

Energy use in the dairy

Every litre of milk leaving the parlour must be cooled quickly and consistently.

After each milking, milk must be cooled to the correct storage temperature, placing a heavy load on refrigeration systems.

Older or undersized tanks can struggle to cool milk quickly, often requiring longer compressor run times and increased electricity consumption.

In some cases, outdated systems may also allow temperature fluctuations that can affect milk quality.

Upgrading to a modern, high-efficiency tank helps ensure milk is cooled faster and maintained at a consistent temperature with less energy.

For Co. Cork farmer Denis O’Leary, investing in efficient cooling with the Dairymaster SwiftCool Milk Tank has made a noticeable difference:

He said: "As soon as the cows are milked, we run it through a plate cooler.

"Anything that's efficient and saving money on a farm is very important."

Why tank efficiency matters

Modern milk tanks, such as those developed by Dairymaster are designed with several improvements that reduce energy demand, including:

More efficient refrigeration systems that reduce power demand;
Improved insulation to maintain low temperatures;
Faster cooling times after milking;
Reduced compressor run time.

These improvements not only lower electricity use but can also help extend the life of the equipment and reduce maintenance requirements.

Planning for the future

As many dairy farms continue to improve efficiency and output per cow, planning storage capacity for the future is becoming increasingly important.

For expanding dairy farms, selecting the correct tank size is also critical.

A tank that is too small for the herd size may require additional cooling cycles, increasing both wear on the system and electricity usage.

Investing in a tank or silo with sufficient capacity helps farmers avoid costly upgrades later and ensures milk can be cooled and stored efficiently during peak production periods.

The Dairymaster SwiftCool Milk Tank and Silo is available in multiple sizes.

Farmers can select a system that matches both their current herd size and future expansion plans.

High-quality construction and efficient cooling technology help ensure milk is cooled quickly and held safely until collection.

Support available through TAMS 3

The Targeted Agricultural Modernisation Scheme (TAMS 3) continues to support Irish dairy farmers who are investing in more efficient infrastructure.

Under the scheme, milk storage equipment such as tanks and silos including Dairymaster’s SwiftCool range can qualify for grant aid, helping farmers upgrade to more modern and energy-efficient systems.

This support can significantly reduce the initial investment required and accelerate the payback period through lower energy costs and improved efficiency.

Why now is the time to act

Energy costs are not getting cheaper, and every day you delay upgrading is another day of avoidable expense.

With support from TAMS 3 and proven technology like the Dairymaster SwiftCool Milk Tank and Silo, find out what you could save.

Dairymaster is offering a free energy consultation for Irish dairy farmers, helping you identify potential savings on your farm.

Booking a consultation could be the first step towards lowering costs and improving efficiency for the years ahead.
