Renewal of the air-conditioning at St. Petersburg´s top hotel in a 3-phase project. The old system has been replaced with the Chiller GRAND Vari™ -system.

Jyrki Tuominen, Managing Director at Ramilax Trading Oy, is an expert on high-quality hotel ventilation cooling contracting after completing the latest Sokos Hotel Palace Bridge project. The renovation of a functioning hotel is a challenging task. Usually, the wings and the floors are renovated. Naturally, the project is suspended during the most busy periods. Occasionally, the hotel has to put the work on hold at short notice when the entire accommodation capacity is required for use.
"Then we just have to clean up and leave", acknowledges Tuominen
When working on a hotel, you cannot come and go as you would at an ordinary construction site. Supplies cannot be stored just anywhere. The hotel guests must be taken into account. The noisy work cannot just be done whenever, and there are strict rules on dust and cleanliness. The work must proceed without attracting any attention and it must be on schedule.
This is particularly important in a five-star luxury hotel.
DIFFERENT AND EXITING
The seven-storey Sokos Hotel Palace Bridge, completed in 2007, is located in the historic centre of St. Petersburg, on Vasily Island.St. Petersburg sights, the Hermitage, Nevsky Prospekt and St. Isaac's Cathedral, are located within walking distance. There are 319 rooms in the hotel.
The competition on the emerging St Petersburg hotel market is intense. Sokos Hotel Palace Bridge has vastly improved its position after the renovation.
In addition to a beauty salon and a fitness centre, the hotel´s fantastic wellness centre opened last year, with its six pools and eight saunas, one of which is an exotic snow sauna.
With its old heart, Sokos Hotel Palace Bridge stands out even from the new top hotels in St. Petersburg. Up until the revolution, the brick warehouse built in the mid 1800s served as the wine cellar of the St. Petersburg Jelisejev merchant family. Now, for example, a wonderful restaurant, Dans Le Noir, where you can enjoy a surprise menu in the darkness and where the patrons are served by blind waiters, or guides, is located under the old arches beside the wellness centre.
Visitors can also experience luxurious rooms, with marble bathrooms. Such luxury also requires five-star cooling and ventilation.
"We want to provide our customers with a high-quality environment, strengthening the St. Petersburg Sokos hotel brand", says Service Manager Jaakko Mäkelä.
Five-star indoor climate
The company, founded six years ago by Jyrki Tuominen, who became familiar with the construction market in Russia whilst working for YIT, is responsible for the project management contract to renew the hotel ventilation cooling. The actual installation and construction work are done by local partners. At most, 20 professionals have been involved in the job; HVAC technicians and electricians, as well as carpenters. The contract work was executed in three parts. The work started in spring 2012 and will be completed in March 2013.
The air in the GRAND Vari™ system is forced along the ceiling surface to the room, draught-free. The devices are extremely quiet due to the tight structure and the sound-attenuation chamber in the blowing channel. Only a pleasant and draught-free indoor climate can be felt in the room.
The GRAND Vari™ system, developed as a terminal for air-conditioning and ventilation in hotel rooms, was selected on the advice of a HEVAC consultant.
"The devices are energy efficient, of high quality, easy to install and easy to clean. Their low sound level is important in top hotels", says Tuominen.
"We settled on this reliable system", confirms Mäkelä. The GRAND Vari™ system is very energy-efficient. In normal hotel rooms, the power input consumed is 3 …11 W, so the annual energy consumption is only a fraction of that of older solutions.

Easy to install
Tuominen praises the easy installation of the device. This is important on a hotel construction site, where the installation work must adhere to schedule without fail.
"The installation of the GRAND Vari™ solution is very straightforward, as the devices are mounted through fasteners on the base plate onto a fixed ceiling surface.
The hotel housekeeping has praised the system for being so easy to clean. The filter can be vacuum-cleaned or washed by quickly lifting up the hinged grille.
The automatic cooling and ventilation controller was renewed in connection with the renovation. GRAND Vari™ can be delivered from the factory with a pre-wired automatic controller. Sometimes we are forced to come up with exceptional solutions, quickly.
Even when the installations of the automatic controllers were running late and the units had to be put into operation, the speed control was bypassed with a 9-volt battery, and it was operating like this for a couple of months!"
Deliveries to St. Petersburg were completed on time
"Secure and timely deliveries are essential in such a project. The job must not be delayed, but the equipment cannot be stored at the construction site indefinitely. I have to say that Chiller turned out to be a really flexible supplier", comments Tuominen.
