Vegetables for the region of Moscow: Cooling efficient at high humidity

Vegetables for the region of Moscow: Cooling efficient at high humidity

In its new central vegetable warehouse in the region of Moscow, the wholesaler Moskovskij Kombinat established cold stores which are individually adjustable in terms of room temperature and relative humidity. Güntner air coolers and Güntner fluid coolers/dry coolers provide a consistently high quality of the fresh goods and an efficient heat dissipation on the 20.000 m² storage space.

Eurovent Certification

Eurovent Certification Eurovent Certification

Which benefits do you as a customer have?

Güntner has the high standard of producing high-quality, application-oriented heat exchangers and remaining both fair and transparent. That is why we participate in a corresponding program from Eurovent. The goal of the Eurovent Certification Company is to promote fair competition and to guarantee the customers that the units on the market are inspected under the same conditions and that they are therefore easier to compare. The manufacturers’ specifications are examined by independent laboratories for this purpose. To do this, units from the respective manufacturer are selected randomly.

The HE Program (Heat Exchangers for Refrigeration) for heat exchangers of the refrigeration and air conditioning industry has existed since 2001. Güntner has participated successfully without interruptions since the implementation of the program; all of the series included in the program are certified without exception – and have been for 15 years!

The Eurovent certification of the HE Program includes DX evaporators and condensers that are designed for R404A, R134a, R507A, R407A, R407C or R407F.

The Eurovent certification program is designated for air coolers with fluids, NH3 evaporators and condensers as well as CO2 evaporators and condensers, 60 Hz units and centrifugal fan units. A certification for CO2 gas coolers and CO2 DX evaporators as an individual group of units is scheduled from 2017.

Operating certified units provides you with significant advantages that are worth real money:

  • The classification of units into energy efficiency classes is an important characteristic of the certification providing you with information on the energy consumption you can expect from the selected unit. This means the operating costs can clearly be identified.
  • The independently measured, inspected specifications give you certainty when it comes to designing the units. You can design precisely to the operating point; safety margins are not required.
  • Units are easier to compare with each other thanks to certified specifications. This results in fair competition under realistic conditions.
  • The certify-all principle guarantees that manufacturers cannot distinguish themselves through individual “top-seller” units: Complete series are certified, hence there are no loopholes for individual units.
  • The confirmed and therefore reliable technical data increase the investment security and guarantees planning security and operational reliability with regard to performance and energy efficiency of the entire system. The operating costs can clearly be calculated right from the beginning.
  • Certified units save real money: “We recommend that every operator calculates the energy consumption for a current or future construction project because of a hypothetically insufficient capacity. A few years ago, non-certified units showed insufficient capacities of up to 35 % in a serial examination. Thus, you can realistically expect a reduced output of 15 – 20 % for calculation. In comparison, there is a clearly better payback period for the certified unit, usually clearly under 2 years”, according to Peter Roth, Eurovent officer at Güntner.
  • The Eurovent certification of the selected units is an indispensable prerequisite for receiving subsidies from defined funding programmes. The certification applies to all standard units. Through its modular variability, the new Güntner product structure includes an even wider range of certified units that come into question for funding measures.
