r-tec RAPID 85 (HPVC Motor)

Overview

The standard driver behind the ALKUR HPVC fast PVC door is the r-tec RAPID 85. With its 85 Nm torque class, 2.0 m/s high opening speed and integrated Ø140 aluminium drum, it takes on the role of key drive motor for cold chain, food production, pharmaceutical facilities and industrial lines that demand fast passage. Depending on the site’s infrastructure, it runs with either an FU (220 V) or an I-380 (380 V) control board.

HPVC + RAPID 85 — system logic

HPVC door wraps PVC fabric vertically onto a drum — soft fabric is used instead of conventional sectional door panels. This architecture means:

• High speed — 2.0 m/s = ~5 times that of standard sectional (0.4 m/s)
• Interior climate protection — Fast passage = minimum cold air escape
• Drum wrapping — Fabric is wrapped 3-4 turns on Ø140 aluminium drum
• Soft start mandatory — Hard start wears the fabric

RAPID 85 is specifically designed for this architecture; installing conventional sectional motors on HPVC shortens fabric + drum life.

FU vs I-380 — control selection

Facility supply	Recommended control	Description
220 V single-phase	FU	Generates 3-phase inverter from single-phase (2 200 VA)
3 × 380 V three-phase	I-380	Direct 3-phase drive, 10% energy efficiency
3 × 230 V three-phase (old facility)	FU	I-380 requires 380 V

→ New facilities are mostly 380 V three-phase → I-380 primary. Existing residential/small facilities 220 V single-phase → FU mandatory.

Speed importance — cold-chain example

In an HPVC door between cold storage (-25 °C) and shipping area, every second of interior climate escape = energy cost:

• Standard sectional door (0.4 m/s): 3 m height = 7.5 sec open
• HPVC + RAPID 85 (2.0 m/s): 3 m = 1.5 sec open
• Forklift passage frequency 100/day → 600 sec/day vs 150 sec open difference
• Annual energy saving: ~30% cooling load

→ RAPID 85’s 2.0 m/s speed is not just operational speed but direct energy + interior environment control gain.

Target projects

• Cold storage HPVC door (food, pharma, logistics)
• Production line partition door (automotive, white goods)
• Food facility clean area / dirty area separation (hygiene + speed)
• Pharmaceutical sector GMP clean room door
• Fast-passage loading ramp front
• Automotive sub-supplier narrow passage

Field discipline

• Soft start calibration — Ramp duration is set to 1.5-2 sec via FU/I-380 trimpot; harder ramp wears the PVC fabric
• Drum wrap tension — Periodically check fabric tension on Ø140 drum; loose wrap causes fabric crease during opening
• PVC fabric quality — 900 gr/m² standard; reinforced 1100 gr/m² for heavy work or cold chain
• Thermal protection — Motor thermal value monitored on high-frequency open-close (30+ cycles/hour)
• Limit switch — RAPID 85 uses standard limit switch for position control
• Periodic maintenance — Once every 3 months drum wrap + fabric tension + reducer oil check
