Winterwarm heating solutions For more than 87 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. 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.

(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 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 22 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.

The special heatexchanger and improved air flow realize optimal heat outputs with low water temperatures. The WWH-LT can also be used for cooling provided that the heat pump is suitable for that application. Characteristics • low temperature heating • good air circulation • EC motor as standard • low electricity consumption • stepless control • 4 capacities • comfortable temperature distribution • various discharge possibilities (when also applied for cooling: only horizontal) • can be used for cooling • integrated condensate collection box • 8 suspension points M10 • IP 54 Sustainable choice Discharge possibilities 9 Measurements The range of 10-80 kW is subdivided in 3 models. The model of the heater is the first number of the type name (1,2 or 3).
