The invention of the drain and overflow system with emptying function permits the complete drainage of all residual water via the jet and air duct drainage system, thus ensuring hygienic conditions in the bath. A successful cooperation is launched with POLYPEX GmbH, one of Austria’s leading bathtub manufacturers.

Since this year, the company has operated its own in-house electroplating unit where all brass parts are carefully chrome-plated, as well as an in-house paint shop where all visible parts can be coated with any sanitary colour. In the same year, the first air jet worldwide is built at Koller.

Starting activities in former Czechoslovakia is a major step for the enterprise. This growth provides Koller with a broader base for the international market. Development, however, remains rooted in Austria.

The first plastic injection moulding machines is put up in a small rented building in Jindrichuv Hradec where manufacturing is started, ensuring the usual Koller quality and functionality. The new machines make the enterprise more flexible and allow it to offer its products in different materials.

This unique technology is a revolutionary invention in the field of whirlpool assembly. The infinitely variable fittings are designed such that each fitting simply fits into its counter piece - without any pipe in between. Since this year, air blowers have been produced and manufactured in-house.

Rudolf Koller founds Koller Malta Limited – from there, international customers are served in many different languages.

The novel nozzle, also called “Water Jet”, is a pure water nozzle and works without any air being added. This results in a completely new and more intense massage effect.

The development of the C-profile series for jet pumps and air blowers substantially facilitates the assembly of the devices. In this year, Rudolf Koller is awarded the title of “Kommerzialrat” (Councillor of Commerce) in recognition of his merits as an Austrian entrepreneur.

Fine Austrian S.L. is established in Spain. From there, Southwestern Europe and South America are supported. Assembly is further optimized, too. The click-in technology is a revolutionary connection system which facilitates the assembly of mini, midi and micro jet nozzles.

In this year, Koller launches two important developments on the market: Nano Jet, the small nozzle for even better whirlpools, and the Flatline series: these nozzles, suction fittings, switches, lamps, air regulators, etc., are very flat and combine an extraordinary design with quality and functionality.

Rudolf Koller founds Koller UK Limited in England to optimally support customers in Northern Europe from there. In the same year, the enterprise starts its own pipe and hose production.

By completely converting CNC production and the grinding shop, and by connecting the electroplating unit to the new automatic COSMAP 7-axis grinding and polishing machine with an exhaust system, the production plant in Vitis is upgraded to the latest state of the art, thus also creating new apprenticeship training positions in the area of CNC production and surface technology / electroplating.

Infrared heating production and launch of sales in many variations and dimensions. Installation of a Canon Océ Arizona flatbed printer for digital glass print of our IR-panels. 2016 production methods are further modernized in many fields.

In addition to our ERSA solder for automatic lead-free soldering of circuit boards, we also put a digital coat thickness measuring device in operation. Furthermore the electroplating process is aligned with the new drinking water ordinance. Therefore we are as partner in the whole sanitary industry at the cutting edge of technology.

The convection air furnace is the universal oven for heat treatment of general cargo. Whether aluminium, steel, brass or copper, the convection air furnace is the ideal system for heat treatment and stress-relief annealing of parts. It can be used for heat treatment at temperatures up to 600 degrees. The furnace is equipped with an inner steel housing and the heating takes place by means of electric tubular heaters. The heat energy generated in the furnace interior is passed through an electric fan to the workpieces. Special feature: In order to avoid oxidation of the articles, it is possible to anneal parts by means of nitrogen. (Free of annealing colours)

This grinding and polishing machine allows an economical production of parts in medium to high quantities. Due to the clamping technology, parts up to a diameter of 350mm can be machined. In a work order it is possible to grind the parts on 3 stations, polish on 3 stations and to clarify on a station (high-gloss polishing).

With this modern 5-axis milling machine we are able to produce complex parts with the highest quality standards in series production. The spindle speeds of 18.000 rpm and programmable feed rates in the X/Y and Z-axis of up to 20m/min also allow the production of free-form surfaces in the highest surface quality.
