As-tech offers you high quality service for heating systems. Products are from International Daikin and Hoval companies.
 Thermal, boiler equipment
Hoval products and systems engineering for energy-efficient heating systems for civil and industrial construction.
From 40 to 50% of energy production accounts for heat. Being expensive, it must be used efficiently and economically. To achieve these goals, Hoval has long been designing and developing technical innovations for equipment heating and ventilation systems. In the first place puts Hoval efficient energy production, along with the highest quality products and technical perfection. Using his potentsal and working closely with partners, Hoval steadily moving forward on the path of development and technology upgrading heating and ventilation systems present and the future. All this is done to ensure the comfort of our customers and users.

Wet cooling tower and evaporative condensers
Cooling tower device for cooling large quantities of water directed stream of air. Sometimes referred to as cooling towers cooling towers.
Currently tower are primarily used in the circulating water for cooling the heat exchangers. In the civil construction of cooling towers used in air conditioning, refrigeration condensers for refrigeration plants, cooling, emergency generators. In industrial cooling tower used for cooling the refrigerating machines, shapers, plastics, with chemical cleaning agents.
The cooling process is due to the evaporation of the water drain-off of its thin-film or droplets on special Sprinklers, along which the water movement in the opposite direction of the air stream.
Evaporative coolers and condensers provide cooling by evaporation. In such systems, the excess heat is transferred from the fluid to be cooled (it may be oil, oil emulsion, glycol, chemical solutions) through the heat exchanger to the environment.
Evaporative coolers are used for cooling fresh water, without polluting its precipitation.
It is an effective alternative to dry cooling using finned tubes and fans, as well as an outdoor cooling towers connected to the plate, shell and tube or tubular heat exchangers. As a direct evaporative cooling occurs on the surface of the tube bundle, in which the cooling fluid, here combines the advantages of both evaporative and direct cooling: low final temperature of the liquid and the ability to do without the pipelines to connect additional cooling equipment.
