ACM Unititan E HR Rolling Shutter Central Motor 140Nm 125 KG in Oman

Description

Measure your shaft and corona before ordering this ACM Unititan shutter motor

A central motor is bought by fit, not by name. This one is built for a 60 mm rolling tube with a 200 mm corona ring, and if your existing shaft is 76 mm or your spring box is a different diameter, it will not go on. That single check causes more returns on central motors than every other factor combined.

The source data we received for this unit quotes a 205 mm spring box and an 80 mm spindle, while ACM dealer data for the Unititan HR E quotes a D200 corona and a D60 tube. We are reporting both rather than picking one. Send us a photo of your shaft end and a tape measure across the spring box, and we will confirm the correct version before anything is shipped.

140Nm or 170Nm, the ACM Unititan E HR central motor capacity conflict

The Unititan family is sold across several capacities under one name, commonly 125, 140, 170 and 180 kg. The listing we sourced this from calls it 140Nm and 125 kg. ACM dealer data for the Unititan HR E lists 170Nm and 170 kg on the same designation.

Treat the name alone as insufficient. What you should be ordering against is the weight of your curtain, not the model badge. Weigh or estimate the shutter first: a solid steel curtain runs heavier per square metre than a perforated or aluminium one, and an underrated gearbox on an oversized curtain will burn out inside a year. We stock the wider range in ACM rolling shutter motors if your measurement points to a larger unit.

What the ACM Unititan shutter motor does on the shaft

It sits inside the shutter box, coupled to the centre of the spring shaft, and turns the roller directly. There is no chain, no external gearbox and no side plate to accommodate, which is why central motors suit shopfronts where there is no room beside the opening.

The E version carries an electric brake, so the curtain holds where it stops instead of creeping down under its own weight. A manual release is fitted for use during a power cut. Adjustable limit switches set the fully open and fully closed positions.

ACM Unititan E HR rolling shutter central motor specifications

Duty cycle and limit travel on a 140Nm rolling shutter central motor

Two numbers in that table decide whether this motor suits your door, and neither appears in most listings.

The first is limit switch travel of 6 m. That is the maximum curtain length the limit system can set. A tall warehouse or car park shutter above that height needs a different gearbox, not a bigger version of this one.

The second is the 4 minute cut out. This is an intermittent duty motor with thermal protection at 160 C. A shop that opens once in the morning and closes once at night will never approach it. A loading bay shutter cycled every few minutes through a delivery shift will, and the motor will stop until it cools. If your door works that hard, tell us and we will quote a continuous duty side motor instead from the full rolling shutter motor range.

The rated temperature ceiling of 55 C is worth a thought in an unventilated shutter box on a west facing shopfront in Muscat or Sohar during summer. Ventilate the box where you can.

Rolling shutter central motor installation across Oman

Fitting a central motor means dropping the curtain, removing the shaft, mounting the gearbox at the centre and resetting the springs. It is not a bolt on job and it is not one to attempt with the curtain still loaded, because a released spring shaft carries real force.

Our engineers fit these in Muscat, Sohar, Nizwa, Sur, Salalah and Duqm, and a fitting visit can be added to the order. Remote operation is not built into the motor, so if you want handheld control, add a receiver and transmitters from remote controls.

What is supplied with the ACM Unititan shutter motor

The gearmotor and its manual release are supplied. A control board, a wall button box, a receiver, remotes, the capacitor mounting, cable and the corona ring itself are not confirmed as included by the supplier. Assume you are buying the motor alone and price the rest in. Fixings and control parts are listed under accessories.

The price is 70.000 OMR. Stock is held in our Muscat shop and delivery reaches all eleven governorates. Installation and any spring rebalancing are quoted separately once we have seen the door.

Before you order, send your shaft diameter, corona diameter, curtain height and an estimate of curtain weight through the contact page. We will confirm the correct version in writing. To compare against side mounted options, start at the Doors Auto shop.

ACM Unititan shutter motor FAQ

Is the ACM Unititan E HR 125 kg or 170 kg?
Our supplier lists this unit at 140Nm and 125 kg, while ACM dealer data for the Unititan HR E shows 170Nm and 170 kg. Confirm with us against your curtain weight before ordering, because the family is sold in several capacities under one name.

Will it fit my existing shutter shaft?
Only if the shaft is the matching tube diameter and the corona ring matches too. Measure the tube and the spring box and send us both figures, since a 76 mm shaft needs a different version.

How tall a shutter can this motor handle?
Up to 6 m of curtain travel, which is the limit switch range. Taller doors need a different gearbox.

Can I use it on a shutter that opens many times an hour?
No, not comfortably. The thermal cut out is 4 minutes, so a loading bay or car park door cycled constantly will overheat and stop until it cools.

Does it come with a remote control?
No. The motor is supplied without a receiver or transmitters, so add a control board and remotes if you want handheld operation.

Does the curtain stay up if the power fails?
Yes. The E version has an electric brake that holds position, and a manual release lets you open the shutter by hand during an outage.
