GÜNTNER’S COMMITMENT TO REDUCING ENERGY CONSUMPTION CAN BE SEEN IN ITS PRODUCTS AND PLANTS

Back to Our Impact

As each year goes by, the world’s demand for energy increases. And despite the growing use of renewable sources, most of the energy we generate still comes from burning coal and fossil fuels. This, in turn, creates the greenhouse gases that are heating up our planet.

At Güntner, we take our environmental responsibilities very seriously, and we aim to minimize the use of energy both in the products we design and in our plants around the world where we manufacture them.

Güntner’s GMMnext smart controller optimizes the energy efficiency of an entire refrigeration system. It is designed to automatically adjust system operation to reflect changes in load, weather conditions, and operating requirements, allowing energy consumption to be cut by up to 30%. The controller also initiates daily cleaning of the heat exchanger block, preventing unnecessary energy use from soiling.

In cooling systems using Güntner’s hydroBLUTM technology, the GHM smart controller offers an energy-saving mode that prioritizes adiabatic cooling as the primary method for maintaining system temperatures or pressures, reducing the units’ energy consumption. Although this means an increase in water usage, the patented Güntner algorithm optimizes the volume of water necessary for the given ambient conditions. The GHM controller also has an efficiency mode that allows users to prioritize either electricity or water usage based on cost.


“IN ADDITION TO STRIVING TO MAKE OUR PRODUCTS AS ENERGY EFFICIENT AS POSSIBLE, WE REALIZE THAT WE NEED TO EXAMINE OUR OWN INTERNAL PROCESSES IN ORDER TO BECOME A TRULY SUSTAINABLE COMPANY.”

Güntner is also taking significant steps to reduce energy use in our plants and offices. Specific actions include the following:

ASIA
At our plant in Surabaya, Indonesia, a new drying oven has been installed that cuts drying time by almost 50% and reduces energy use by around 70%. Energy was being expended when lights were not turned off during break periods; this has been remedied by introducing a timer system for the lighting.

EUROPE
At our plants in Sibiu, Romania, and Tata, Hungary, a new powder coating process that can reduce the amount of gas required for heating by around a third has been introduced in the manufacturing process. Originally stemming from Güntner’s Thinkit program, which gave colleagues the opportunity to develop innovations on a sustainability theme, the process involves the use of a different chemical mix that works at much lower temperatures than before.

At Sibiu, air circulation and insulation projects aimed at stopping heat loss from the two factories have resulted in annual gas savings of around a third. In Tata, a much more efficient gas boiler for water heating has been installed, saving around 700 cubic feet of natural gas per operating hour.

NORTH AMERICA
At our offices in Mexico, we have begun a project to install smart thermostats for air conditioning. So far, they have been introduced in the two main central systems spaces and have reduced energy consumption by 30%. Shop floor lighting is also being updated with LED lights, which use considerably less energy than traditional incandescent lighting and also last far longer.

SOUTH AMERICA
Switching to renewable energy whenever possible is as important as energy conservation. Currently, Brazil’s energy supply consists of 85% renewable energy, with 60% coming from hydroelectric plants.

Consumers have the choice of buying their electricity from a distribution company or entering a free market and buying it directly from a generator or trader. The latter option offers the opportunity of using energy that only comes from renewable sources, and this is the route that our Güntner plant in Brazil will soon be taking.

Starting in 2024, our plant will use only green energy, making us the first company in the country to reach this important sustainability landmark. We will be 100% certified, demonstrating our commitment to sustainability.


“ALL OF US HAVE A DUTY TO CONSERVE ENERGY WHEREVER POSSIBLE, AND I’M PROUD OF THE MANY EFFORTS THAT GÜNTNER IS MAKING IN THIS AREA. WE CONTINUE TO LEAD THE WAY IN SUSTAINABILITY FOR OUR INDUSTRY.”
