Door curtains solutions
Energy Savings with GUARD PRO Door Curtains – Neuman Aluminium
Our long-standing collaboration with Neuman Aluminium Fliesspresswerk Slovakia s.r.o. in Žarnovica has brought innovative solutions for efficient heating and energy savings. For many years, the company’s production halls have relied on the reliable ADRIAN-RAD E dark gas infrared heaters, ensuring even heating throughout the spaces. In recent years, however, we have focused with the customer on further optimizing operational costs and increasing energy efficiency. The solution turned out to be the GUARD PRO industrial door curtains, which we are gradually installing at the most frequently used entrances to the halls. These curtains create an effective air barrier, preventing heat from escaping the hall during cold days and blocking cold air from entering from the outside. The result is not only reduced heating costs but also improved working conditions for employees, especially near frequently used entrances.
GUARD PRO door curtains have proven to be an effective solution that, under ideal conditions, can reduce heating costs by up to 12%. The customer was so impressed with their efficiency that they decided to continue their gradual installation at additional entrances to their production halls. This project clearly demonstrates that the combination of ADRIAN-RAD E and GUARD PRO technologies not only delivers energy savings but also provides higher thermal comfort and overall improvement of the working environment.
You can see the current results from the latest installation in the photos below. If you're looking for solutions to save energy and optimize heating in your facility, don't hesitate to contact us. We would be happy to prepare a tailor-made proposal for you.
Boost Energy Efficiency with Air Curtains: Success Stories from ADIENT and VÚB Bank
Air curtains have long been a valuable addition to heating or cooling systems, helping to significantly reduce energy costs. After installing the curtains, we saw an additional savings of up to 12% in monitored locations. They help retain the indoor heat or cool air that's already been produced and paid for, while also protecting the space from dust, dirt, and other external elements.
Check out photos of our latest installations: ADIENT SLOVAKIA in Lučenec, a major automotive manufacturer and long-time user of the GUARD PRO 200W air curtain, decided to equip another gate with this system. Similarly, the VÚB bank in Fiľakovo demonstrates the ideal use of the GUARD 100W hot water curtain in a commercial setting.
Air curtain at the STOP SHOP
In cooperation with the renowned supplier of heat and building management services ENGIE, we started with the replacement of the original air curtains with electric heating for the new GUARD 200 E. The first pilot project turned out to be excellent and we completed a demonstration installation in the area of the STOP SHOP business zone in Lučenec. Unlike the original appliances, modern and compact SONNIGER air curtains already use PTC electric cells for heating, which increases their efficiency and life cycle.
Door curtain in the Children's Faculty Hospital
At the beginning of 2024, we were approached by the Children's Faculty Hospital in Banská Bystrica to solve the door draft at the entrance to the lobby of the emergency room. This problem was observed for a long time, but it became more serious last fall as the older entrance door was replaced with an automatic one with a motion sensor. The frequent opening caused that the reception and the buffet workers were directly and long-term exposed to the influence of winter and door drafts, which caused them discomfort. To solve this problem, we chose a 2 m air curtain, horizontally installed above the lobby entrance door. The door contact turns on the air curtain when the door opens with the fact that an authorized person can set one of the three fan speeds on the controller.
Horizontal set of industrial curtains
REMARKPLAST company from Vráble dealt with thermal energy loss through the open gate by doubling it and installing a high-speed gate in near proximity. Although this partially permeable barrier did reduce heat loss, however, not to a sufficient level. After consultation with our technicians, we suggested a horizontal set of industrial air curtains with electric heating, installed above the gate. This ensures a really strong protection against cold air penetrating into the space and heat leakage at the same time. Increased thermal comfort will clearly lead to increased work productivity.
Reducing the energy consumption of buildings with door curtains
Minimizing heat loss using door curtains is a proven and effective solution. Even in the renowned company NEUMANN ALUMINUM, fixed energy costs are reduced in reasonable ways. We are currently working for them with our partner ŠALIGA s. r. o. and we installed door curtains without heating on the other two gates. Considering the type of gate and the method of opening, as well as the layout of spaces around, we agreed on mounting from the side of the gate, while the width of the opening allows the use of the door heaters from only one side. Since the flow and velocity of blown air are essential for the effectiveness of the solution and the operation did not require heating passage zone, we used appliances without heating and an exchanger. The curtain is a self-supporting structure that is fixed to the floor and side wall. Additional elements designed by the customer will protect it from the danger of impact of the handling equipment.
New ambient door curtain installation
For the premises of ZF SLOVAKIA a. s. in Levice, we delivered GUARD PRO air door curtains without heating for our partner installer MERAX SK s.r.o. The general contractor was IN VEST s.r.o. One-sided installation vertically up to a height of 4.5 m was sufficient. In the summer, these devices create a barrier against the penetration of heat into the premises, and in the winter they help to achieve significant savings on operating costs and save energy. Door curtains are a good choice when the gates are opened frequently, when the heated space is quickly ventilated, they also prevent the penetration of insects, dust and odors. The investment return on door curtains is usually within two years time.
Saving energy is worth it
More and more of our customers are realizing that the cheapest is energy that they can save themselves. One of the ways is also the protection of large industrial gates against the escape of a huge amount of heat from the production hall. For this purpose, it is ideal to use powerful door curtains. Whether they decide for gas, hot water, electric or even module without heating, it is always an effective and simple solution. Our clients also chose this path: Inipex s.r.o., Mar s.r.o., Rona a.s. etc. Each of the companies has its own production program, but these door curtains will reliably serve everyone. Ecological paper straws, table glass, metalwork - cold air is strictly prohibited from entering the hall. And that's the point.
Eltek has decided for door curtains
The company ELTEK from Liptovský Hrádok asked us for a solution of door heaters for an industrial gate, through which they load material and ship products at frequent intervals. Due to the complicated layout of building construction elements (such as passenger doors) and the inappropriate type of gate opening for horizontal installation, vertical assembly from one side of the gate was chosen. Installation of hot water distribution systems, wiring and door curtains was handled in cooperation with Ing. Peter Zábranský. The company's building has a boiler room, the output of which was not used to its maximum, and therefore it was possible to install door curtains with a GUARD PRO 200W hot water exchanger. Hot water door curtains have the fastest start-up and thus ensure that the heat losses of the heated space after opening the gate are as low as possible. With a correctly used heating system and a correctly chosen technical solution for door curtains, it is possible to save up to 12 % of annual heating costs.

Adient Slovakia s.r.o., hot-water door heaters
Door heaters or in other words "air curtains" demonstrably eliminated the building's energy losses. We connected the air ducts with hot water heating to the existing boiler room, which underwent renovation. In the summer, the clones will be operated without heating and will thus create a natural and effective air barrier.
