We would like to introduce ourselves...

ELMAK® is a developer and manufacturer of innovative systems, devices, chemicals, procedures and methods for the application of water as a technical process medium and as drinking water, including the production of pure water for steam autoclaves.

Our concept...

In order to meet the current technological needs, ELMAK® has further developed multiple functions in beyond the current state of the art, and patented its own methods where progress meant breaking new ground.

The mission is, whether old or new, to increase and maximize efficiency and productivity of systems with new technologies. This secures the capital investment of existing systems, saving replacement. The savings finance the investment, usually within a few years. Summary: Improvement through maintenance is the simpler way.

Main areas of application

HVAC, Solar heating, photovolatic : cooling and chilled water - hermetic and open : temperature controlled systems open and hermetic : drinking water anti-stagnation, anti legionella : cooling towers - evaporative and legionella protection : chemicals, corrosion protection and water treatment

Cooling towerts atm. open with precise ELMAK® PP Water Master water control. No exessive water loss through blow down.

Cooling tower support technologies and water treatment in complete exchangeable modules.

Wind generator: Top cooling water for E-Converters, sealed circuit, vacuum degassed, TSS < 5µ, max. corrosion protected, no mineral and bio-scaling, self monitoring

Prime HVAC through intelligent use of the evaporative cooling and controls with ELMAK® PP ”Water- Master“

.. Prime HVAC Technology Module with chiller support for summer peak loads. In total the lowest possible energy use is applied for the maximum cooling performance.

Modernizing the old status quo, hermetic operation including ELMAK® Vacuum-Degassing


Steam free vacuum degassing in hermetic systems helps the corrosion protection. Form above 10 years with our method - below 6 months without.

Automatic water exchange and water care in temperature controlled systems in the plastics industry. Drainage Timer (right above).

ELMAK® Cooling tower water control system PP WaterMaster

The new control system:
chemical equilibrium precise charge amounts Blowdown without excessive water loss Disinfection Frost protection Savings potential 50-75%






Legionella, fouling and stagnation stop in drinking water networks.

ELMA-LAVAR is a cold process combatting stangation of drinking water with the help of ExV vessels. No heating, no chemical treatment.


Cleaning of Central Heating

first clean and then stop corrosion. ELMAK® ExV vessels secure the automatic operation. i.e. pressure, corrosion free, degassing, water filling- with alarm. Note: only clean systems ensure the most efficient heat transfer.

Pure water vacuum degassing

for pure water steam generators in autoclaves.
Conforming to DIN EN285 for NKG
Pure water recirculation. Advantage: Energy savings. Cold process without steam.



Chemicals and Water protection

Water chemicals are not an end in themselves, rather a tool to precisely set the few parameters that can't be managed physically. We produce special formulations for specific problems.

ELMAK® ExV

membrane-less expansion vessels prevent the known problems with pressure and filling levels. Uses: HVAC Drinking water and all other hermetic systems Works against contamination and legionella

Filling Device

pneumatic, level controlled for make up in temperature control units and heating systems. 5 bar to 19l

Temperature control units

From old to new: automatic water exchange with control unit and drainage valve for re-preparation in the AF-Station.
