VALO Hotel & Work is a novel concept for a business hotel with 24/7 services. The hotel’s 422 rooms are transformed into working spaces during daytime, offering its clients flexible and versatile working environment with all encompassing hotel amenities. Inspiring event and conference premises enable private meetings as well as gatherings for larger groups of people. The luxurious customer experience is completed by unique restauration and well-being possibilities.

The first VALO hotel was completed in early autumn 2020 at Helsinki’s Mannerheimintie. More info can be found at:

High Metal Oy designed and manufactured a 9m x 3m stainless-steel swimming pool and a circular 4m stainless-steel whirlpool for VALO Hotel & Work’s wellness area.

Water handling and the related technology was supplied by Suomen Allaslaite Oy

”The project went smoothly. High Metal’s customer service and their ability to find solutions to the customer’s needs were on a very high level,” recounts VALO’s Project Manager Hannu Riikola.

”The pools were delivered on time and the installation went according to our plans.”

In the summer of 2020, High Metal Oy delivered its largest ever swimming pool designed for private use. The pool was installed to a private property located in the Espoo archipelago. The delivery included a 21m x 4m acid-proof swimming pool, a massaging shower, a stair landing equipped with jets and a sliding covering.

See a video below about the project:

The swimming pool is used year-round and is therefore equipped with an efficient water purification system to obviate the need to empty the pool for cleaning.

High Metal delivered the 16m x 4m RST infinity swimming pool by the Vesijärvi beach and the 2.5m x 4m RST hot tub for the sauna section.

Digitalisation of dairy product processing

High Metal Group developed and made a new-generation cottage-cheese production line and the related control system. Production processes for the 18,000-litre cheese vat are controlled by a smart system, and each stage of the overall cheese-making process, from primary production onwards, can be remotely monitored and controlled.

All product development, design, manufacture, automation and electrical design were done at High Metal Group’s premises in Vantaa.

The hood is easy to dismantle and pack for transportation. Assembly is quick and easy, based on using tongue-and-groove joints to connect the honeycomb elements.

Metos Oy Ab is one of High Metal Oy’s closest and longest-standing partners. Over the years, the companies’ values have developed in tandem and both have a customer-oriented operating model. Metos’s service package for professional kitchens covers the entire chain: equipment installation drawings, equipment, training in equipment use, and maintenance and spare-part services. As a top player in its sector, Metos is an autonomous business group belonging to the Italian ALI Group.

High Metal Oy is manufacturing dish returning and sorting units for Metos’s dishwashing units, which take care of 300–2,000 diners. Metos and High Metal engage in the continuous product development of accessories for dishwashing systems. Around 200–300 of their jointly developed systems are delivered in various versions around Europe each year.

The diagrams below show the trend curve for dish returning systems from the 1980s to the 2010s.

We redesigned a plinth which, according to Fem’s calculations, is stronger and more vibration-resistant than the previous version. The new plinth has a sheet metal structure. It weighs 5.2t, compared to the previous version’s weight of 17t, being 72% lighter than the original and creating cost benefits, as well as material savings, at various work phases: Cutting -60%, edge trimming -65%, welding -68%, machining -90%, packaging -10%, transportation -60%.

The MKT ultrasonic washing machine cleans cheese moulds effectively

Valio’s Äänekoski cheese dairy entered the ultrasonic era in the spring of 2017: It uses an ultrasonic washing machine made by MTK to clean moulds and salting boxes used in the manufacture of the world-famous AURA blue cheese.

Water-jet washing machine replaced with ultrasonic equipment

Cleanliness is a key issue when making high-quality cheese. For example, failure to clean a cheese production line will soon affect product quality, and a prolonged cycle of soiling could create a breeding ground for dangerous microbes. Proper cleaning processes are needed on cheese production lines to guarantee sufficient cleanliness.

Valio’s Äänekoski cheese dairy, which focuses on the production of blue cheese, used to clean its cheese moulds with a water-jet washing machine connected to a central washing unit for the entire production line. Because the washing solution circulated through the central unit, residue from the moulds could spread through the production line, necessitating frequent changing of the solution. In addition, a significant amount of heat was wasted when cleaning the moulds, which prompted Valio to seek a better solution.

“We wanted a solution for cleaning cheese moulds and salting boxes that was better suited to our processes. We also wanted to raise production capacity,” explains Jarmo Kelloniemi, a cheese expert from the Valio Äänekoski cheese dairy.

Because Valio’s new ultrasonic washing machine works separately from the central washing unit, the solution used for the production line is not soiled by dirt from the moulds. The object being washed is immersed in the ultrasonic washer’s basin, where ultrasonic elements separate any dirt. This makes washing more effective and kinder to the environment, using lower quantities of chemicals.

A tailored solution requires effective cooperation

Kelloniemi explains that Valio knew special tailoring would be needed to integrate the new washing machine with the production line, and that not everything was likely to work perfectly from the start. For this reason, they hoped that the equipment manufacturer could continue close cooperation in developing the washing machine after its delivery. They were aware of MTK’s strengths in this respect.

“We had several tenders on the table, but the cooperation aspect was decisive. In terms of manufacture, installation and aftercare, MKT’s solution had the right overall price-quality ratio. In addition, we had seen similar equipment made by MKT and knew that they could provide precisely the washing machine that we needed,” says Kelloniemi.

MKT took a holistic view of the production line

Valio’s new ultrasonic washer is at the intersection of the moulding and salting processes, which makes both the moulds and salting boxes easy to wash. The solution saves both space and time. Achieving this was by no means easy.

“Obviously, if you use the same washer to wash two objects of different shapes and sizes, you have to spend some time, as in this case, getting the adjustments right. Despite initial challenges in cleaning the salting boxes, we found the right solutions together with MKT and got the washing process to function in the way we wanted. We had other challenges in the cheese production line, unrelated to MKT, but they helped us to fix them at the same time.”

“I can recommend MKT’s ultrasonic washer and believe that ultrasonic technology will play a bigger role in cheese dairies in the future, particularly for washing cheese moulds,” says Mr. Kelloniemi.
