The key elements of racks and dryers exposed to corrosion (such as frames, levels, angles or shelves, as well as depot lockers structures) are made of high-quality galvanised steel. During the final stage of production, all elements are subject to automated powder coating. Galvanised steel and a thick layer of coating provide double protection for the products against moisture. In addition, the rack structures have been designed to prevent water accumulation inside the

The main rack and dryer models are available in four different visual options which differ in the design of the front column. The Standard line is featured by a classic anthracite frontside, whilst the MiniPanel line by a modern white panel with a contrasting solid handle. The Panel line is distinguished by a wide, elegant board with an oval stainless-steel handle attached to it; the UniQ line offers unlimited possibilities for the selection of materials, which includes a delicate casing of a wide front column with a comfortable inner handle. The choice of different visual lines enables QBL products to be properly matched to the interior design and character of the facility in which they are used.

The running system of QBL products includes a rail set or a set of swivel casters. The rail set consists of stainless steel rails 2 or 3mm thick (depending on the length of the racks), connectors, rail endings, and 12 standard bearings attached to each frame of rack or dryer. The design of the rails and the number of bearings used guarantee smooth and safe movement of the products – even when fully loaded. The set of swivel casters includes four durable casters (with a diameter of 75, 80 or 125mm) which are selected according to the needs and the maximum possible load on the structure.

The Wind model of dryers use a heating system based on separate modules – each consisting of a fan and a heater. The drying modules are placed in 9 of the 11 shelves (excluding the lowest mounted shelf on each side). The shape of their structure and the high efficiency of the fans used ensure a sufficiently high pressure of the air flow. The bottom surface of each shelf has numerous openings through which heated air is blown into the boots placed below. The shelves are made of galvanised steel and their fixing height can be adjusted to the size of the stored boots. Units with shelves and built-in heating modules combine the functions of dryers and storage racks.

Double-sided boot dryers – Optiflow, Force and Wind models – are operated through 5"colourful touchscreen built into the side wall of the main control cabinet. A large, sensitive display and an intuitive application make navigating the menu and managing all available functions of the device very simple and friendly. In addition to a range of functions of the dryer, the screen allows you to select, among other things, one of the six available language versions. There is also an automatic ‘lock screen’ function to prevent unauthorised control of the device. The communication between the user and the Panel models is ensured by a touchscreen 3.5".

The electronic dryer control system allows efficient and customised operation of the dryers. Its functionality is demonstrated by the availability of multiple useful settings and intuitive control of individual functions of the device (e.g. heating temperature, disinfection or time controller). The double-sided dryer models are divided into three independent segments. The operation of each of them can be adjusted individually by stopping their work or by setting one of three modes: fan, fan with heaters and work according to pre-set time intervals. The timer function allows individual operating modes to be set for each hour of each day of the week separately. The electronic control system helps to optimise the operation of the appliance while increasing drying efficiency and energy savings.

The drying systems consist of highquality industrial components – durable and adapted to continuous, uninterrupted operation. Each of the components used – and which affect the efficiency of the dryer (i.e. primarily heaters and fans) – were subjected to long-term tests, also in conditions of increased humidity and a wide range of ambient temperatures. Careful selection of individual elements with specific performance parameters, as well as optimal selection of their configuration, number, or appropriate location in the construction of the equipment – ensure the dryers’ (especially double-sided models) exceptional durability and drying efficiency. It is possible to use components suitable for electric networks with different parameters (including 110-120V AC).

Protection of electrical systems against overheating and damage to components in each dryer for boots, helmets or gloves is ensured by a bi-metal thermal protection system. The Force, Optiflow, Wind and Panel models are additionally equipped with independent systems of programmable thermal protection – thanks to which, the heating systems are automatically cooled down in the event of a failure or a sudden, undesirable shutdown of the device. All models of QBL dryers and all carefully selected components have CE declarations of conformity.
