A recuperator is a device which makes additional use of the energy of exhaust gases, which would otherwise be lost through the chimney. In practice the recuperator is a heater, which is installed between the boiler and the chimney. The waste exhaust gases at a temperature of 220° C are conducted through the recuperator and keep heating the supply water of the steam boiler or feedback water of a hot-water boiler. Consequentially the exhaust gases cool off, while the supply or feedback water is additionally heated, which means approximately 5 % of additional efficiency for recuperators of type I totalling to 95 % (applies to steam boilers).
Recuperators of type I are made of steel, while additionally a stainless steel recuperator of type II can be integrated, which brings approximately another 3 % of savings totalling to 98 % (applies to steam boilers).
We produce shell and tube heat exchangers from carbon or stainless steel.
Heat exchangers are thermal machines where the heat from one media is transferred to another. In practice, they are used for cooling oil, for steam condensation in central heating systems and as boilers for hot tap water. The heat exchangers can be made from steel or stainless steel. The pipes inside the heat exchanger are according to the TIG welding procedure welded to the flange of the heat exchanger.
The heat exchangers are produced in various types: U-shaped, helical, with even pipes, conducting several parallel currents through the heat exchanger.
The production includes Thermex hot-water and steam boilers. These boilers are made to the highest quality standards and are robust featuring an efficiency of up to 95 %. By integrating a recuperator, the boiler efficiency is additionally enhanced. The tangential input of exhaust gases into the exhaust pipes results in vortex movements by the exhaust gases without the need to use turbulators. Consequentially, the cleaning of the boiler is considerably easier and more cost effective since the turbulators do not need to be dismantled and cleaned.
General overhaul of hot-water and steam boilers by the following manufacturers TVT-TAM-STADLER, EMO Celje, Ðuro Ðakoviè, Weiss-Toplota, Kohlbach, Loos, Viessmann, Omnical, TPK.
Boiler overhauls have several advantages compared to acquiring new ones:
* During the overhaul all vital components of boilers are replaced (exhaust pipes, duct walls, combustion chamber... ) making them as new from the aspect of their performance, efficiency and lifetime;
* Price of the overhaul does not exceed 50 % of the purchase price of a new boiler;
* The services provided carry a three-year warranty;
* Boiler overhauls are performed on site which is important for boiler rooms difficult to access. This makes construction as well as installation works unnecessary, there is also no need for lifts and permit application or any other additional administrative procedure.
