“I had to respond to a tank at Aarhus Harbor, where I received an alarm on my G7c for high CO levels. Shortly after, my colleague called to check if I was okay, as he could see on his phone and computer that the CO levels around me were above the threshold. At the same time I received a personal alarm, my colleague got an SMS and an alert on his open computer indicating that I was in Aarhus at these GPS coordinates, and that there was a CO level of xx ppm. It’s fantastic and makes you feel safe, even when working alone.”

Nyborg Distillery

Located in the former workshop for DSB freight trains, Nyborg Distillery is set in a beautifully restored high-ceilinged building. The old workshop has been transformed into a vibrant space that includes not only the distillery but also a restaurant, bar, and shop. Geopal gas detectors ensure the safety of this historic site by monitoring for ethanol and other potential hazards.

Stauning Whisky

Situated near the west coast, just a 10-minute walk from the quaint village of Stauning, Stauning Whisky is safeguarded by Geopal’s gas detection systems. Since signing an agreement in 2015 with Diageo and Distill Ventures—one of the world’s largest spirits producers—Stauning Whisky has embarked on expanding its distillery. Our AGA systems provide daily, effective detection of ethanol, propane, and CO2, allowing the skilled team at Stauning Whisky to focus on their craft without worrying about safety.

Hot Work

Crossbridge Energy

Crossbridge Energy (formerly Shell Refinery) in Fredericia relies on large mobile systems for welding operations. Given that employees are constantly moving around the area during welding tasks, combined with the surrounding environment and welding equipment, dangerous situations can arise. Geopal’s mobile systems continuously monitor the work area, ensuring the safety of employees wherever they are located. This allows workers to feel secure, even when welding in explosive (EX) areas.

DONG

DONG in Vejen uses the GPB-02C construction site panel for hot work at their MR stations. This panel helps maintain safety during welding and other activities by providing real-time monitoring and quick response to any potential gas leaks, ensuring a secure working environment.

Marine

NAVIGATOR

The NAVIGATOR is one of the world’s largest factory trawlers, featuring a 1.5 MW cooling capacity for freezing and storing catches. Due to its extreme cooling power, the vessel carries 9 tons of ammonia, making it crucial to have accurate alarms and prompt action in the event of a leak. Geopal detectors are employed to monitor various cooling compressors and associated systems on the NAVIGATOR. This ensures optimal safety and security for the vessel’s crew, effectively safeguarding them against potential hazards associated with ammonia leaks.

Power Plants

Haderslev Power Plant

At Haderslev Power Plant, the operation involves handling flammable gases, which introduces a risk of explosion. Geopal’s AGA systems continuously monitor methane concentrations to ensure safety and prevent potential hazards. Haderslev Power Plant is a sophisticated waste-to-energy facility located in Haderslev. The plant handles waste incineration and manages the associated risks of flammable gases, making reliable gas detection critical.

Hillerød Power Plant

The Hillerød Power Plant, situated in Hillerød on Zealand, northwest of Copenhagen, operates with an installed capacity of 77 MW. Managed by Hillerød Forsyning, the plant uses gas for its operations, and Geopal provides methane and natural gas detection solutions.

Svanemøllen Power Station

Geopal has supplied AGA systems to Svanemølleværket, a gas-fired combined heat and power plant, on several occasions. The most recent installation included a significant rack system designed for detecting methane in relation to the setup of Boilers 21 and 22.

Per Pedersen: “We work with Europe’s best producers of cooling systems, but the gas detectors that come with the systems are often poor quality. They are continuously replaced with Geopal gas detectors because they simply work, and the prices are reasonable.”

Henrik Storm: “There are rarely issues with Danish-produced systems, but we often experience that even the most competent suppliers in Italy and Germany equip their cooling systems with detectors that fail quickly. We’ve encountered detectors that failed after just a few weeks, which is unacceptable for us and our customers in environments that require constant monitoring of toxic and flammable gases like ammonia, HFO R1234ze, propane, and CO2. That’s why we switch to Geopal whenever another detector fails. Besides the quality of the detectors, Geopal’s service department is also a plus. They always find a solution and proactively call when it’s time for service. I appreciate their proactive approach because it means Per and I don’t have to keep track of it ourselves – we already have plenty to do.”

NH3 Solutions

“At NH3 Solutions, we use Geopal’s gas alarm systems in the cooling systems we produce because we find them to be thoroughly tested, high-quality, and reliable, which enhances our confidence as manufacturers of cooling systems and reassures our customers. Additionally, we rely on Geopal’s service department for maintenance of the gas alarm systems we are responsible for at our customers’ sites. We find their technicians to be skilled, competent, and friendly. We greatly value the collaboration with Geopal, who are always ready with help and advice, and always with a smiling and welcoming attitude.”

Teaching Facilities

“After a period with other suppliers, we contacted Geopal around 2010 and equipped some of our rigs at Risø with their gas sensors. It worked so well that in 2012 we installed their room monitoring in two new buildings, and the results were just as convincing.

Since then, we have been using gas detection equipment from Geopal because their equipment simply works – it’s straightforward, logical, user-friendly, and reliable. So the choice was not difficult when we had to select a supplier for the AGA system for DTU B310. In this building alone, over 160 Geopal gas detectors are installed, and we expect to continue having very low service costs and a service organization that works really efficiently.

We have a very critical mixture of flammable and toxic gases in the pipes running through the building to our laboratories – H2, CH4, O2, CO2, CO, NO, NH3, and many special gases, and for the sake of both people and research processes, it is extremely important that the failure rate is as low as the safety level is high. If the detection system fails, experiments are shut down, causing researchers and students to lose time and data. Their samples might be damaged, forcing them to start over, which costs oceans of time and money.
Therefore, our detection system MUST simply work, and with my previous experiences, I am confident that we now have a reliable and dependable system that we can fully trust.”

Jens Borchsenius / DTU

At TEC in Hvidovre, they offer more than 30 vocational training programs, such as bodywork smith, warehouse worker, truck mechanic, motorcycle mechanic, and many others. This means a wide range of workshops. Common to the various workshop training programs is that carbon monoxide leaks can easily occur. We have installed detectors in the workshops that can measure the levels of toxic carbon monoxide, ensuring the safety of the students as much as possible.

Tunnels

Nordhavn Tunnel

When driving through the Nordhavn Tunnel, your safety is secured by Geopal gas detectors. In the event of an accident where a vehicle leaks gasoline or another substance, the spillage is collected in sumps. From there, the air and vapors are continuously extracted for hydrocarbon monitoring. The extracted air passes through Geopal detectors, which will trigger an alarm if the hydrocarbon levels become too high.

Underground Parking

AiRFORCE

“We have collaborated with Geopal for many years, primarily for the delivery of gas detectors for parking ventilation systems, which is our primary market. We experience Geopal as a professional partner with transparency, quick execution, and exceptional service. They have great insight into gas detection systems, and their employees are always ready to assist with technical aspects related to this.”

Mads Sønnichsen / AiRFORCE

FläktGroup A/S

”As a company, we have had Geopal as our preferred and sole supplier of gas detectors for our own developed parking garage ventilation systems since 2012. Quality, service, and support have always been top-notch. Geopal is always ready to help, whether it’s assisting a technician in a parking garage close to handover or sharing knowledge about explosive vapors or harmful gases.”

Jeudan

This three-level parking facility for 500 cars is located under Kvæsthusmolen, near the Royal Danish Playhouse in central Copenhagen. Geopal supplied GP-BUS detectors for detecting carbon monoxide, nitrogen oxides, and hydrocarbons. These detectors activate the ventilation system if harmful gas concentrations become too high.

Copenhagen Municipality

Copenhagen’s first fully automatic underground parking facility is located on Nørre Allé. Similar facilities were later built on Leifsgade (Islands Brygge) and Under Elmene (Amagerbro). In all three parking facilities, Geopal installed AGA systems for detecting CO, NO2, and hexane, ensuring the activation of ventilation if harmful gas concentrations rise.

Tuborg South Waterfront

This modern shopping center, spanning 16,000 m² and including a two-level parking garage, opened in spring 2007. Geopal provided gas detection for carbon monoxide and petrol fumes. The parking garage is divided into two ventilation zones on each level to ensure optimal use of the fans. A total of 96 GP-SA and GP-CO gas detectors with integrated microprocessors are installed in the parking garage.

UPS and Battery Room

DFDS Transport/DSV

Geopal has installed AGA systems in several charging areas at DFDS Transport/DSV. The system monitors the development of hydrogen in the areas, and if the hydrogen content in the air reaches 5% LEL, the system automatically activates ventilation. At 25% LEL, the power supply is immediately cut off, stopping the battery charging process. This installation has allowed DFDS to reduce ventilation, resulting in savings of at least 50,000 kWh per year. Additionally, they save energy by reusing excess heat from the charging areas instead of venting it outside.
