ALKUR High-Speed Roll Type Rapid PVC (HPVC)

Overview

Rapid PVC doors (HPVC) enable uninterrupted entry-exit of forklifts, pallet jacks and other service vehicles with high opening-closing speed; at the same time they establish insulation against odour, heat, dust and wind factors between spaces. The high-speed roll type HPVC is a compact system in which the door fabric is wound up onto a drum in the upper chassis and gathered upward. It saves space on internal lines with low ceiling height while withstanding hundreds of open-close cycles per day.

The archived TÜV NORD technical-report cover dated 14 May 2010 identifies a Type ECO high-speed foil door with an Mtec drive. Because only the first page of the report is available, this record is not used as a current series certificate or as performance evidence for other HPVC configurations.

Structural features

• Fabric — 900 g/m² panama-weave imported PVC; long-lasting, flexible, chemical resistant. A transparent window section can be added at the desired place/size.
• Side post — 80 × 80 mm extruded aluminium profile, RAL 9006 (grey). Aesthetics + ease of maintenance.
• Drum — Ø125 mm special-section aluminium tube. The fabric is wound as a single layer, gathered in the upper chassis when the door is open.
• Bottom skirt — Aluminium profile RAL 9006 + EPDM seal underneath or RAL 3002 red fabric alternative. Sealing + safety detection integrated.

Motor + control selection

According to door size, 5 RAPID motor models are selected; each motor can be used with a control unit either with or without inverter.

Motor	Voltage	Shaft Dia	Speed	Capacity	Power
RAPID 35	380 V	25.4 cm	130 rpm	35 Nm	0.55 kW
RAPID 45	380 V	30 cm	90 rpm	45 Nm	0.55 kW
RAPID 75	380 V	25.4 cm	130 rpm	75 Nm	0.55 kW
RAPID 85	380 V	30 cm	90 rpm	85 Nm	1.00 kW
RAPID 180	380 V	40 cm	90 rpm	180 Nm	2.20 kW

Without inverter (I-380 control)

3-phase mechanical control — simple + robust. 0.65-0.70 m/s opening speed. For budget-priority or medium-speed typical HPVC applications.

With inverter (FU control)

Frequency inverter — soft acceleration + speed + torque control. 1.5 m/s opening speed (RAPID 45/1 + FU) — for modern forklift traffic. Thanks to soft start/stop, fabric wear is significantly reduced; integrated encoder position control.

Safety layers

• MF/A safety photocell — Standard, prevents the risk of trapping at the door threshold.
• BREAK OUT bottom impact safety — Optional; in case of accidental impact by a forklift or vehicle, the bottom skirt profile accidentally comes out and returns to place when fully opened. Critical for product+door protection in heavy forklift traffic.
• Anticrash system — Optional; automatic reopening + calibration after impact.
• Full-height photocell — Full-height light curtain (premium safety).
• Optical IR eye — High-sensitivity proximity detection.

Target projects

• Food and pharmaceutical production lines — Hygiene + temperature separation + heavy forklift.
• Cold storage — Keeps HVAC loss to a minimum, sealing brushes + EPDM seal mandatory.
• Logistics warehouse zones — Transits with heavy forklift traffic; flow accelerates noticeably with the 1.5 m/s inverter model.
• Car park entry control points — Pedestrian + vehicle safe transit (transparent window critical).
• Store back-office to sales area separation — Customer-invisible section transit.
• Automotive production facilities — Line separation + paint booth insulation.

Evidence scope

• Historical source: TÜV NORD technical-report cover, DIN EN 13241-1:2004, Report No 10 325 380263-001, 14 May 2010.
• Identified test object: Type ECO high-speed foil door and Mtec drive; test date 19 March 2010.
• Use boundary: the published copy is only page 1 of a 13-page report. Without the result pages, no conclusion is drawn about mechanical resistance, speed, insulation or safety performance. See the historical document archive.

Field discipline

• Opening size — For the correct RAPID motor + control combination, the dimension verification form must be obtained from and completed by authorised dealers.
• Mains voltage — 380 V three-phase (with I-380 or FU) or 230 V single-phase (only with FU) option. The facility’s existing installation capacity must be checked before installation.
• Ceiling height — Roll-up drum Ø125 mm + steel construction = approximately 40-50 cm needed for the upper chassis.
• Fabric wear — Hard starting (without inverter) fatigues the fabric more quickly than with inverter; in heavy use the inverter model is straightforward in the long term.
• Periodic maintenance — Every 6 months 1 EPDM seal + drum axis + motor thermal check. Every 3 months in heavy forklift traffic.

Model notes

The high-speed roll type is typically preferred for medium-small openings with forklift traffic + indoor applications. For openings wider than 5 m or windy outdoor environments, ALKUR Folding Type HPVC is recommended — it offers high wind resistance with galvanised steel 200×200 mm side posts + Ø25 mm galvanised tube fabric reinforcement.
