4 EURO-AIR European Association of Air Heater Manufacturers For almost 90 years now, Winterwarm has been engaged in the development, production and sales of heating systems for the industrial, agricultural and retail markets. We achieved a leading position in the European market by focusing on three things: quality, service and innovation. We are proud of our program of high end, sustainable products among which air heaters, heat pumps, air curtains, thermostats and more, which all contribute to a comfortable climate in buildings at an efficient energy consumption. Whether it is a warehouse, a poultry house, a factory or a supermarket. Looking forward to a sustainable future With all expertise we have gathered in the past years Winterwarm can play an important role in the energy transition. We continuously do research for new “green” heating solutions with a low carbon footprint and try to improve our existing product program. At this moment Winterwarm offers various sustainable heating solutions such as hybrid heaters (heat pump + booster), electric air heaters and water-supplied air heaters (in combination with a heating network, heat pump or boiler). When solar panels are present, our electric heater EH (industrial) or DX-EH (agricultural) are a good solution for the sustainable heating of industrial premises c.q. poultry houses. And where a gas-fired unit air heater is still the best solution for the moment, we have high-efficiency condensing air heaters HR available or for in poultry houses the efficient DXC gas fired heaters. Sales and support in the UK It is important to us that we can adequatelysupport our dealers in all countries. In the UK we have had our own sales office in Warrington for many years now where our experienced staff takes care of the UK and Irish customers. They supply support on day-to-day business activities such as order status and can provide advice on new projects or resolving any problems with heaters. Our website provides you with all kind of product information 24/7 and we continuously invest to improve our on-line service. All heaters, accessories and spares can be ordered through our Web Shop. Sustainable in day-to-day business In addition to manufacturing sustainable heating solutions for our customers, our new factory is the most sustainable building in Winterswijk, Green Leaf municipality 2022 herself. The new business premises has received a BREEAMOutstanding certificate, which means that it meets various sustainability criteria at the highest level. A number of those criteria concern health, energy use, circularity of materials, land use and ecology. We are very happy to be able to take the next steps towards sustainable heating in this beautiful building together with our sister company WinLed Lighting Solutions.

Winterwarm World Wide 5 High quality product development Winterwarm has its own R&D department which continuously works on the development of new products and the improvement of existing ones. Our goal is to provide our customers with a reliable product of high quality for a reasonable price. Our product range consists of 90% products which we engineered ourselves in the past 20 years, for as well the industrial market as the agricultural market. At this moment our R&D focuses on the development of sustainable heating solutions. Quality from top to bottom Since 1992, Winterwarm has been ISO certified (ISO 9001:2015). Periodically the whole process of product engineering and development, production, delivery and after-sales service is audited by KIWA (the national gas institute in the Netherlands). Consequently, we continuously work to improve all aspects of our company processes. Before a heater leaves our factory, it is submitted to an extensive final test. This provides extra assurance to the installer and his customer that the heater will function well immediately after installation.

WWH LT-series with HPX heatpump WWH-LT is a waterheater that, in combination with the HPX heat pump, forms an all-electric heating solution that can also provide cooling. Alongside the QSE and QSG, it is one of the most sustainable heating solutions for larger commercial or industrial spaces.

WRU-series 20 Winterwarm Radiant Tube Winterwarm presents the WRU-series: gas-fired radiant tubes which provide a comfortable warmth. Radiant heat is experienced as a very pleasant warmth equal to sun radiation; the thermostat can even be set a few degrees lower than usual! Especially suitable for bad insulated halls, circumstances where only part of a room needs to be at a certain temperature (like warehouses with packing area) or environments where no air circulation or draughts are allowed. The WRU is a U-tube available in 8 capacities. Information on linear types/herringbone systems/ double linears available upon request. Characteristics WRU: • rapid heating up times • no heat loss through the roof • energy saving • no air movement • no floor space required • plug in control box • maximum efficiency because of patented reflector system Measurements

(When more than 10 modules are necessary, extra support is required.) Winterwarm ACM Winterwarm presents a modular air curtain. The modular construction enables you to assemble an air curtain for each door width. The ACM creates a comfortable room climate, prevents drafts and intrusion of polluted outside air. Characteristics: • applicable for all doors with a height of 4,5 m. or less • modular construction • vertical and horizontal positioning possible • possibility to place underneath overhead-door • high air output • innovative application of Gurney flap which results in a relative high-air speed at floor level • adjustable louvres to create optimum air flow • low weight 5 6 1 2 600 806 4 3 Vertical mounting set Attention: in vertical position the air curtain is less effective.

WCU-series 26 Destratification fans Nowadays buildings are well insulated; this limits the required heating capacity in a room. In this situation, however, it is very important to achieve a good recirculation of the warm air in the room by installing destratification fans. The installation of a destratification fan pays for itself quickly because of the significant energy savings. All WCU models are available with EC-motor which reduces the electricity consumption with 25%. Winterwarm has 2 types of destratification fans: recirculation unit WCU and a 3-blade ceiling fan Rendovent. Characteristics destratification fans: • extra circulation of warm air • reduced heat losses • increased comfort • temperature gradient drops • energy savings • WCU IP30 • Rendovent IP20 • option: EC motor • stepless control air volume (WCU-EC) provided with 4 suspension screws ø10 mm 1 5 WCU, for installation in rooms from 5 to 12 m. high Recirculation unit WCU Ceiling fan Rendovent Typical installations Install destratification fans always at the end of the throw (to prevent air swirls) or above a location which is not reached by the air current of the heater. The WCU fans are all as standard provided with a room thermostat 230 V. and a socket connector.
