DN Tanks -

DN Tanks has over thirty years of experience designing and building tanks for energy related markets. Owners can efficiently and cost effectively store energy in our Thermal Energy Storage (TES) tanks.

Stratified chilled water TES tanks are an integral part of large district cooling systems. Our TES tanks help reduce energy and operational costs, defer capital expenditures on equipment replacement or expansion projects, prevent downtime of mission critical operations, improve the efficiency of natural gas power plants with turbine inlet cooling systems, or provide owners with negotiating leverage in deregulated utility markets.


GEA-ACC - The GEA Air Cooled Condenser is used in applications where water is scarce and heat needs to be rejected. GEA built the first ACC in 1939. Since then GEA has supplied over 75% of the world market. The technology continues to evolve in terms of efficiency and availabililty. The “A” Frame design uses finned tube bundles arranged in bays. Durability, Cleanability, High Heat Transfer Coefficients, and High Fin Efficiencies are all a factor in the design.

GEA-EGI Heller System - The Heller System was developed by GEA in the Budapest design offices. It is a unique cooling system which uses Indirect Dry Cooling. The cold end of the steam cycle is air-cooled. Intermediate heat transfer circuits filled with condensate quality water and circulated by pumps is applied. Water films formed by this circuit then condenses the exhaust steam in the Direct Contact Jet Ejector. A fraction of the warm water is pumped to natural draft cooling tower where it is cooled in water-to-air heat exchangers. The system is environmentally friendly, and has proven to save a tremendous amount of water.

GEA-Heat Exchangers Cooling Towers - GEA ranks as the industry leader in the design and construction of Mechanical Draft, Wet Evaporative Cooling Towers for the Power and Process markets. Counterflow and Crossflow designs are available. Film fill is a ‘no or low fouling’ configuration which prevents degradation and loss of performance.
