MUELLER milk cooling tanks

As of the late 1960's the first milk cooling tanks came to Holland to replace the old system of non-isolated, non-cooled, iron milk buckets. The Mueller Model O milk cooling tank was among the first makes to enter the market. As it proved its quality soon, it became the most sold type of milk cooling tanks in the Netherlands. 30 Years hence, the Mueller tanks prove to have a very long lifespan, making them very wanted on the second hand market. HAGRA can offer you a wide range of used Mueller milk cooling tanks in numerous models and measures of capacity varying from 720 liters to over 10,000 liters if necessary. Look at our current stock to see all the tanks that are available immediately.

Indepth information:

Mueller tanks originate from the Paul Mueller Company in Springfield, Missouri, USA. As of 1988 all Mueller equipment sold in Holland is produced by SSP Lichtenvoorde b.v., under licence of the Paul Mueller Company.

The O-type

The predominant type of Mueller bulk milk coolers is the O type. In comparison to other makes, the striking oval look makes it easy to distinguish them. This oval form provides a very quick cooling effect, especially on the first milkings. The Mueller O-type is well-known for its low power consumption, which makes it very appropriate for warm environments and climates.
An other benifit of the Mueller O-type is the highly finishing due to a supreme polishing workmanship. No other brand of milk cooling tanks can withstand a comparison with the Mueller O-type tank where the finishing is concerned, both on the inside as on the outside.
All O-type tanks are made of AISI 304 (DIN 1.4301) stainless steel. All Mueller tanks comply with NEN/ISO 5708 standards for milk cooling tanks.
The O-type capacity range varies from 1090 liters to a maximum of 19835 liters.
The table below shows all types, their capacity, and their measures.

The O-92-model

The original O-type of Mueller milk coolers was renewed during the early 90's. Although still rare on the used tanks market, they are worth mentioning. The O-92 has the control and cleaning unit built on the the front of the tank. This reduces the costs of reinstalling considerably. O-92 tanks have a capacity range of 1090 up to 23840 (!) litres.
The table below shows all types, their capacity, and their measures.

The RHS-type

The RHS type of Mueller milk coolers is designed for smaller quantities of milk. As the pictures reveal it is an "open" model, that is, in stead of just a manhole the lid covers the entire top of the tank. RHS tanks have a capacity range of 400 to 1200 litres.
The table below shows all types, their capacity, and their measures.

Tank type	Max. Capacity (in litres)	A (in mm.)	B (in mm.)	C (in mm.)	D (in mm.)	E (in mm.)
RHS 100	420	1600	1025	1395	1100	840

For cooling only?

Besides cooling, MUELLER milk cooling tanks can also be used to heat a fluid or simply to keep it isolated and warm/cold. See storage tanks for further information on this issue.
