New mass-balance controller replaces the classic conductivity controller and opens massive saving potential for water energy and chemical costs.

With ELMAK^® Watermaster we introduce a new patented technology, that offers a completely new way for water management in evaporative cooling towers. While conventional systems perform blowdown mostly using electrical conductivity (EC), the ELMAK^® Watermaster is based on an intelligent regulation of the water-chemistry relevant compounds.

The basis of this process is the chemical equilibrium of the circulating water. Based on a recent water test from the water supplier, the allowed amounts per 100% mixed-water per cycle are calculated. From there we get the so called concentration factor (CF) (GER -EZ). At the same time using the CF the % amounts for evaporation and blowdown are determined. The total is always the cycle amount that remains after evaporation and is removed by blowdown. This is discharged before the start of the next cycle. This maintains the salt balance per cycle. The blowdown water can be used for other purposes and reduces the overall water bill.

The paradigm shift here is the cycle based substance-mass equilibrium. :
Evey cycle is sequentially and measured exactly to the liter. Unplanned blowdowns are avoided by the system completely. Watermaster is an autonomously operating water controller, that saves resources, reduces operating costs and improves the production security.

ELMAK^® Watermaster is conceived for a secure and legally conform operation of cooling towers under consideration of all regulatory requirements.

By means of this patented regulatory method, water, chemicals and energy use are clearly reduced. Simultaneously risks for scaling, biofoulding and unplanned standstills are reduced. The method is suited for old as well as new evaporative cooling tower systems, especially for the cooling of compressor based chillers for HVAC and IT- Computing centre cooling.

"The conductivity does not determine the optimal operation of the cooling tower, but rather the chemical equilibrium of dissolved substances", says ELMAK. "With the Watermaster we begin a completely new technology for water control. The planned cost savings vs existing traditional systems are (depending on type and relevance) from 20-50%."

With  ELMAK Watermaster® we position ourselves as a technology driver for a sustainable and economical water control in industrial cooling systems.
