Infrared diesel heaters
How does the heater work? Answers To Common Questions.
IS AIRREX HEATER SAFE?
AIRREX heater is a very safe heater; it has twelve different safety systems such as combustion monitoring, tilt and overheating sensors.
HOW DO I INSTALL THE HEATER?
The AIRREX infrared heater does not require a separate installation. Fill fuel into the tank, insert the plug into the socket and AIRREX is ready to be used. The wheeled heater is easy to move where you want.
CAN I CONTROL HEATER REMOTELY WITH WiFi?
In the AIRREX app you can see realtime information, for example the temperature in the room being heated, the amount of diesel and whether the heater is running or not. Informative messages are also displayed in the app. The heater can be connected to an existing WiFi network. If there is no WiFi network the heater has a place for an optional 4G router. The heater
can also be used without WiFi.
HOW MUCH IS THE POWER CONSUMPTION?
When the heater starts, it takes 185W. After the start, it only takes 80W when the heater is running.
WHY DOESN’T HEATER SMELL?
When the fuel used is completely incinerated, it generates no odor or hazardous emissions. AIRREX's product development history goes back over 30 years, so the heater’s
function has been fine-tuned very carefully.
DOES THE HEAT SPREAD EVENLY?
Yes. Infrared heat is spread evenly and very far. Many people have an idea that a fan is needed for the heat to transfer, for example to get the heat all the way to the other end of the hall. No fan is needed – the infrared heater heats up materials, walls, floors and all other materials in the space.

How do REX NORDIC Air Conditioners Work? Answers to Frequently Asked Questions.
HOW DOES AN AIR CONDITIONER WORK? Air conditioners transfer heat from one place to another using refrigerant. In heating mode, they extract heat from the outdoor air, ground, or water and transfer it indoors. In cooling mode, they reverse the process, removing heat from indoors and releasing it outside.
IS AIR CONDITIONING BAD FOR YOUR HEALTH? When used properly, air conditioners like the Rex Nordic HP-19 and HP-60 models are not bad for your health; in fact, they can improve working conditions. Both models are designed for more than just cooling or heating; they also help maintain healthy indoor air by cleaning and drying the air. This dual functionality reduces humidity and
minimizes airborne particles such as dust, pollen, and other allergens, creating a more comfortable and safer working environment. Proper air quality is crucial in professional settings, particularly in industries where employees work in hot, humid, or poorly ventilated spaces. The HP-19 and HP-60 help address these challenges by providing temperature control while enhancing air quality, which can reduce the risk of heat-related illnesses and improve overall productivity.
WHAT SIZE AN AIR CONDITIONER DO I NEED? The size of the air conditioner you need depends on the size of the space you want to cool or heat. Rex Nordic offers two models
suitable for different room sizes and capacities. To choose the right model you need to calculate the volume of the workspace (length × width × height in meters). If your space is less than 550 m³, the HP-19 is ideal. For larger spaces up to 1200 m³, the HP60 is the better choice.
DOES THE AIR CONDITIONER DEHUMIDIFY?
Yes, both Rex Nordic HP-19 and HP60 models effectively dehumidify the air while cooling or heating. These capabilities ensure the removal of excess moisture from the air, reducing humidity levels in the workspace. This not only improves comfort but also helps prevent issues such as mold growth and equipment corrosion.
EVAPORATIVE AIR COOLERS
Water cooled mobile air coolers! Perfect cooling solution also for any sultry and dusty environment.
ENERGY SAVING –LOW POWER CONSUMPTION
An evaporative cooler will only increase it's cooling capacity when temperatures rise, without increasing the energy consumption.
HEAT STRESS PREVENTION – LESS LOSS OF WORKING HOURS
A work environment that is cooled, well ventilated and provided with ample fresh outside air, is a healthy work environment with high employee wellness and often higher productivity.
NO FIXED INSTALLATION
Easy cleaning and low maintenance, no installation costs! Thanks to the wheels, you can move the device to the spot where cooling is required.
AIR CLEANING
Evaporative coolers are equipped with a submersible UV-C light. This device effectively kills possible germs and viruses while the tank water circulates through the lamp pipe. It will lower the risk of spreading harmful bacteria.
WHY REX NORDIC?
Evaporative coolers are the best solution for extreme working conditions and for large areas where applying air conditioners is not feasible and other solutions won’t generate the required cooling capacity.
Evaporative coolers are easy to clean, need low maintenance and there’s no installation costs. We offer a 2+1-year warranty on our evaporative coolers.

COOLERS FOR OUTDOORS
Perfect for covered outdoor spaces, these coolers deliver refreshing airflow to keep guests and staff comfortable during hot days. Their mobility and quick installation make them a great choice for temporary event setups.
GREENHOUSES & HORTICULTURE
Greenhouses benefit from cooler air to support healthy plant growth. Our air coolers help lower air temperature, creating a more comfortable climate for plants while being energy-efficient and cost-effective.
FARMS & ANIMAL HUSBANDRIES
In agricultural settings, maintaining a comfortable environment for both workers and animals is crucial for animal welfare and productivity. Our swamp coolers help reduce heat stress in livestock barns and farm facilities, promoting healthier conditions.
LARGE SPACES NEEDING COOLING
Whether in aviation hangars, automotive workshops, or logistics centers, evaporative air coolers can manage temperature in expansive areas where traditional air conditioning may not be feasible.
How do Evaporative Coolers work?
WHY SHOULD I CHOOSE EVAPORATIVE COOLER?
The evaporative cooler provides an inexpensive, eco-friendly, and chemical-free cooling solution without using refrigerants or facing limitations, all while boasting a zero Global Warming Potential.
HOW DOES IT WORK?
When the cooler is on, the fan drags air through the moisturized cooling pad. While the air passes through the cooling pads, water vapor brings the heat away and cools the air down. An effective built-in UV-C light kills possible germs and viruses.
WHAT RANGE OF TEMPERATURE REDUCTION CAN BE EXPECTED?
Evaporative coolers can provide a temperature drop of between 4°C and 12°C when outdoor temperatures are above 22°C. You can connect the
cooler to a water supply and upgrade the cooling effect by adding ice cubes. Ice can cool down the temperature of the water and enhance the cooling effect of the cooler.
WHAT ARE THE KEY ADVANTAGES?
High cooling efficiency without water mist, large air volume, but low power consumption and no installation cost. These features help you cut down power consumption and decrease the
amount of air conditioner usage.
ARE THERE ANY FINANCIAL BENEFITS?
Evaporative cooling systems can be eligible for the Energy Investment Deduction (EIA). As an example, in the Netherlands, this can result in a net benefit of 11% on the entire investment. In other countries, there are also often local subsidies for sustainable techniques.
