Air cooler


Воздухоохладители представляют собой ребристые теплообменники, в которых рабочий флюид нагревается за счет поглощения тепла из окружающей среды, подлежащей охлаждению, не изменяя при этом своё агрегатное состояние. Эти устройства являются компонентами системы и используются, например, для кондиционирования воздуха и охлаждения товаров или помещений.

Испарители представляют собой ребристые теплообменники, которые, будучи компонентами холодильной системы, испаряют жидкий хладагент, поглощая тепло из окружающей среды, подлежащей охлаждению. Эти устройства используются, например, в низкотемпературных системах хранения продуктов питания.


  • On request, according to feasibility

Various material combinations

  • We provide various material combinations and a wide range of available tube and connection systems, so that you can find the solution that perfectly fits your demands.

Special constructions

  • Our technical experts are glad to support you in designing the heat exchanger that precisely suits your requirements.
  • With the high flexibility at the Güntner production sites, even very challenging designs can be manufactured. 

High operational reliability and enhanced leakage protection

  • Due to the proven  floating coil principle the fin coil can expand without straining the fluid-carrying tubes. This prevents loss of fluid as a result of leakage and enhances the service life of the unit.

Customized operating pressure

  • Our standard pressure levels for heat exchangers are 16 and 30 / 40 bar (depending on the application). On request, special designs with pressure levels up to 120 bar are available.

Different connection types

  • Brazed connection
  • Welding connection (standard flange acc. to DIN)
  • Threaded nipple


Precise cooling: Fish production in Vietnam

Precise cooling: Fish production in Vietnam

The new fish factory of Hung Vuong Ben Tre produces frozen food in line with HACCP directives for the European and Russian market every day. About 1,500 employees process approx. 250 tonnes of seafood per day on a total area of 30,000 m². Güntner evaporators, air coolers and coils reliably provide normal-temperature and low-temperature storage rooms and freezers with cold. A thermowave plate heat exchanger is used here to connect the primary with the secondary circuit.

365 days of wintry temperatures in the world's longest ski tunnel thanks to Güntner

365 days of wintry temperatures in the world's longest ski tunnel thanks to Güntner

There are year-round temperatures of about minus 4 °C in the "MidSweden 365" ski tunnel. The tunnel system in the Swedish village of Gällö-Viken was once built for military purposes and recently redesigned for about SEK 37 million to house an indoor sports facility for cross-country skiing for everybody that opened its doors in September 2017. Güntner provided air coolers, heat exchanger coils, an ammonia condenser as well as a dry cooler for this ski tunnel.

Mega salmon factory stays cool

Mega salmon factory stays cool

The world market for salmon products grows steadily. In line with this economic development, also the capacities of the meanwhile largest fish cannery for the processing of salmon grew so that its area now comprises 95,000 m²/1,022,572 ft². The cooling of manufacturing, order-picking and storage areas takes place with refrigeration components from Güntner.
