An electronic system cabinet is not merely a metal enclosure that simply houses 19-inch devices; it integrates device mounting, cable management, accessibility, ventilation, and maintenance requirements within a single mechanical framework. Tempa Pano’s range of electronic system cabinets comprises six product families, ranging from wall-mounted compact solutions to freestanding cabinets with large capacities. Within the official product lineup, CR, MR, and PR models are available in wall-mounted configurations, while EC, ER, and PEC models are designed for freestanding use. This results in a comprehensive product portfolio that allows for easy comparison based on installation requirements for projects involving 19-inch components such as network equipment, patch panels, power distribution units, fan units, racks, and more.
This catalog guide groups the various series under a common heading while preserving the technical differences between them. After all, it is not appropriate to assume that all series share the same level of protection, the same door design, or the same standard equipment. On Tempa’s current Turkish-language product pages, the IP55 rating is explicitly specified for the MR and EC series; for other series, any IP rating not listed on the page has not been included in this information. When making a selection, factors such as the wall-mounted or freestanding type of the cabinet, the height and depth of the unit, the arrangement of doors and side panels, the direction of cable entry, the type of air circulation (natural or fan-assisted), and any required accessories must all be taken into consideration.
The Tempa electronic system cabinet range
Tempa Pano’s official product category page lists six series: CR, EC, ER, MR, PEC, and PR. In their product catalogs, CR is referred to as the “Cool Rack 19-inch wall-mounted cabinet,” ER as the “Eco Rack 19-inch freestanding cabinet,” while PR and PEC are respectively called the “Prime Line” wall-mounted and freestanding cabinets. MR and EC also belong to the 19-inch cabinet category. This naming convention facilitates easy identification based on the installation location: for projects requiring a wall-mounted solution, CR, MR, or PR should be considered; for applications that require a freestanding unit on the floor to accommodate additional equipment, EC, ER, or PEC are the appropriate options.
The selection of a model should not be based solely on its external dimensions. Standard dimension tables provide information on width, height in U, height in millimeters, and depth in conjunction with the product code. After calculating the total U-height of the devices that will be installed within the cabinet, it is also necessary to consider the space required for passive components, power distribution systems, cooling units, and any additional devices that may be added in the future. The depth of a device is not the same as the depth of the cabinet itself; additional components such as front and rear connections, cable routing, power connectors, and service access points must also be accommodated within the available space. Tempa’s 19-inch profiles, which can be adjusted in depth, represent a crucial feature of its product range, as they enable the mounting surface to be positioned according to the specific requirements of the project.
CR Cool Rack: wall-mounted cabinets with natural air circulation
The CR Series is a 19-inch wall-mounted family offered in Tempa’s catalog under the name Cool Rack. The body and glass doors are made of 1-mm steel sheet, while the 19-inch profiles are constructed from 1.5-mm galvanized steel; the surface is painted in RAL7035w. The perforated design of the bottom and top panels facilitates natural air circulation. The space left on the wall side allows for cable passage from either the bottom or top. The glass doors, perforated side panels, and two 19-inch vertical profiles with adjustable depth are the key features of this standard product.
CR, as a wall-mounted solution, can be considered for projects that require ventilation openings to be located within the same enclosure. However, this must be taken into account alongside the expectation that the perforated surface will provide adequate separation from the surrounding environment. Since the manufacturer does not specify an IP rating on the CR product page, the protection level of a different series cannot be applied to CR. The patch panel, 19-inch device rack, and grounding conductor are additional accessories offered by Tempa for this series. The density of cables and the thermal load generated by devices are key project considerations that determine whether natural air circulation will be sufficient.
MR series: IP55 wall-mounted 19-inch cabinets
The MR Series is also a wall-mounted 19-inch cabinet. Unlike the CR model, its official product page clearly states that it meets the IP55 protection rating, with references to TS 3033 and EN 60529 standards. The cabinet’s body and glass door are made of 1.5-mm thick steel sheet, and the surface is painted in RAL7035w powder coating. Other key features include a profile design with ten bends, a PU molded seal inside the door, a cable pass-through plate at the bottom, a detachable screwed-back cover, and a 5-mm polyamide lock with a double-bit mechanism.
The MR hardware includes a body, glass doors, a back panel, a cable-passing plate with gaskets, and four wall mounting accessories. Special dimensions, custom colors, and pre-treated surfaces are available upon request. Additional options such as a patch panel, a 19-inch equipment rack, and grounding conductors are also available as accessories. When evaluating this series, it is essential to check whether the IP55 protection rating, the cable entry at the bottom, access to the rear, and the wall mounting requirements are met. The product code should not be finalized without ensuring that the U-height and depth specified in the standard table match the list of equipment to be installed.
PR Prime Line: wall-mounted cabinets with flexible access
The PR Series is the 19-inch wall-mounted model within the Prime Line family. The frame and glazed door are made of 1.5-mm steel sheet; the 19-inch profiles are constructed from 2-mm galvanized steel, and the surface is painted in RAL7035w. The comprehensive Prime frame comes with a glazed front door, one removable and one hinged side panel, 19-inch vertical profiles with adjustable depth, an air-ventilated dust-proof cover, as well as upper and lower cable pass-through plates – all of which are listed on the product page. This configuration provides a practical and competitive solution for wall-mounted projects that require access from multiple directions and flexible cable routing options.
Standard equipment includes front and rear frames, glass doors, side panels, 19-inch profiles or swiveling frames, ventilated dust-proof covers, and four or six wall mounting accessories. Additional components in the kit list include an upper protective sheet metal, bottom and top sealing curtains, fixed or telescopic 19-inch shelves, a patch panel, a 1U fan unit, a power outlet group, a depth cable profile, and grounding conductors. Since the IP rating is not specified on the product page, the selection description should not imply that this series offers a specific level of protection.
EC series: IP55 freestanding 19-inch cabinets
The EC Series consists of 19-inch electronic system cabinets designed to be installed on the floor. According to Tempa’s Turkish website, the cabinet’s body and panels are made of 1.5-mm thick steel, while the glass-door frames and base are constructed from 2-mm thick steel. The 19-inch profiles also feature 2-mm galvanized steel construction. These cabinets, painted in RAL7035w, possess an IP55 protection rating. Other notable features include handle-operated espagnolette locks with polyamide housings, and PU-sealed door interiors.
The standard components of an EC include front and rear frames, glass doors and backs, side panels, 19-inch profiles with adjustable depth, four or six depth rails depending on cabinet depth, top covers, and bases. Additional options include adjustable feet, wheels, top protective sheets, partial closing curtains, power strip assemblies, telescopic perforated shelves, cable profiles, mounting plates, locks, rotating frames, patch panels, 1U fan units, and cable organizers. When IP55 protection is required, the impact of any additional components such as cable entrances or fans on the overall design of the enclosure must also be verified as part of the project planning.
ER Eko Rack: a ventilation-focused freestanding range
The ER Series is a 19-inch freestanding cabinet also known as the Eko Rack. Its distinctive features include an air-ventilated top, doors that can be opened 150 degrees, a three-point locking mechanism, glass or perforated front and rear doors, removable perforated side panels, and 19-inch vertical profiles with adjustable depth. The top of the cabinet is equipped with a fan grill, while the bottom features a cable pass-through grid. The product’s components also include the front and rear frames, glass doors, back and side panels, a base, the air-ventilated top, and four 19-inch vertical profiles.
For ER systems, various complementary components are available, such as adjustable feet, wheels, power strip units, fixed and telescopic shelves, mounting plates, depth guides, rotating frames, patch panels, 1U fan units, and cable organizers. Options including glass or perforated doors, as well as ventilated upper sections, enable the configuration of air circulation and access arrangements according to specific project requirements. However, it should be noted that the ER product page does not provide an IP rating; moreover, any unspecified protection level mentioned in the description of ventilation options should not be taken as an official specification.
PEC Prime Line: configurable freestanding cabinets
The PEC is a 19-inch freestanding cabinet belonging to the Prime Line series. Although the term “pdr-serie” appears on Tempa’s website, both the page title and the official product catalog refer to it as the PEC Series. The frame is made of 1.5-mm steel, the panels are 1.2-mm thick, the glass doors consist of 1.5-mm steel, and the base is also made of 2-mm steel. It is specified that the 19-inch profiles are fabricated from 2-mm galvanized steel. The cabinet features a front door painted in RAL7035w, a lockable and removable back panel, ventilated removable side panels, and 19-inch profiles with adjustable depth.
Brushed cable transition plates and cable profiles of two different depths enable efficient cable organization. Options such as fan-equipped, filtered, or perforated enclosures, along with single-piece or modular rotating frames with hinge-mounted backs, allow for customized access and air management systems to be implemented according to specific project requirements. The standard configuration includes front and rear frames, glass doors, lockable backs, side panels, a base, an air-ventilated dust cover, and adjustable profiles. Special dimensions, colors, surface treatments, custom racks, and mounting plates can be provided upon request. Since the IP rating is not specified on the PEC page, comparisons should be based solely on the mechanical features listed.

Project data for selecting the right cabinet
The first step is to create an inventory of the devices. For each device, it is necessary to record its U-height, physical depth, weight, front and rear connections, as well as power consumption. When calculating the total U-space required, not only active devices but also patch panels, cable organizers, power strip units, shelves, fan units, and any reserved expansion space should be taken into account. When selecting a wall-mounted model, the wall’s load-bearing capacity and the space required to open doors for maintenance must be confirmed; for a freestanding model, the use of wheels or feet, as well as the accessibility around the cabinet, must be verified according to the project requirements.
The second step concerns service access. Front-only servicing and frequent access to rear cabling require different door and back-panel arrangements. CR’s removable sides, MR’s removable back, PR’s hinged side panels, ER’s perforated door options, and PEC’s lockable or hinged back options therefore matter when comparing specifications. Check that panels can actually open at the installation location and that removed components can be handled safely.
The third step involves cable and air management. The direction of cable entry, the routing of power and data lines, the position of the power strip, and the degree of bending all affect the depth of the enclosure. Components such as ventilated covers, perforated surfaces, fan curtains, and 1U fan units must be specified solely in accordance with the relevant series’ standard specifications or accessory lists. The number of fans or their cooling capacity should not be determined without knowing the power consumption of the devices installed within the enclosure or the prevailing environmental conditions. In projects requiring a certain level of protection, the door, seals, cable entries, and all additional ventilation components must be considered together.
Quotation and project planning checklist
