Sws seceurodoor 77 insulated traditional chain drive 240v motor 22g steel insulated roller shutter doors

SeceuroDoor 77 Insulated Industrial Roller Shutter (Single-Phase Chain Drive)

The SeceuroDoor 77 Insulated with a single-phase 240V external chain drive motor is a high-quality, double-skinned steel roller shutter built to a robust 'Traditional' industrial specification. This model provides an excellent balance of thermal performance and accessibility, making it the ideal choice for medium-sized commercial and industrial openings where three-phase power is unavailable or unnecessary.

Combining the strength of insulated steel construction with the proven reliability of a GfA chain drive system, this door offers a significant upgrade over standard single-skin shutters. The minimal additional cost is far outweighed by the benefits of enhanced thermal efficiency, acoustic reduction, and quieter operation in windy conditions.

Single-Phase Chain Drive Technology

At the heart of this door is an externally mounted GfA single-phase 240V chain drive motor. GfA motors are universally recognized as the market leader, offering cutting-edge technology and intelligent control options.

• Standard Power Supply: The 240V configuration connects directly to standard UK mains electricity, eliminating the need for three-phase infrastructure and reducing installation costs significantly.
• Enhanced Torque via Chain Drive: The external chain drive mechanism provides a mechanical advantage, delivering higher torque capacity than compact tube motors. This is particularly beneficial for the heavier insulated curtain on medium-sized doors.
• Serviceability: The external motor mounting allows for superior accessibility during routine maintenance without needing to dismantle the door assembly.
• Medium Usage Rating: Single-phase 240V motors are typically specified for medium usage openings with average daily use. They provide excellent reliability for typical commercial applications with moderate daily cycles.

Insulated Curtain Construction

The curtain features a 77mm high profile slat with a 15mm depth (front to back). Each slat is filled with a CFC-free foam injected core, providing superior strength and rigidity compared to any standard single-skin profile.

• Double-Skinned Steel: Galvanised steel as standard for maximum corrosion protection and durability.
• Thermal Efficiency: Heat transmission of 4.01 W/m²K helps maintain stable internal temperatures and reduces energy costs.
• Structural Integrity: The foam core offers significantly more strength and reduces deflection across spans.

Thermal and Acoustic Benefits

The SeceuroDoor 77 Insulated combines the robustness of the popular SeceuroDoor 75 with the added advantage of insulation and enhanced acoustic performance.

• Quieter Operation: Because the slats have a deeper profile, more weight, and sit tighter in the guides, the curtain is significantly quieter—especially in high winds where single-skin doors tend to rattle.
• Energy Efficiency: The fine-pored PU rigid foam infill and minimal thermal bridges ensure good thermal insulation, while advanced curtain and sealing technology reduces noise transfer from both inside and outside the building.
• Cost-Effective Upgrade: This is a great insulated roller shutter door for so many applications and worth considering over a single-skin basic shutter, as the extra cost is minimal compared to the benefits offered.

Single-Phase vs Three-Phase: Making the Right Choice

Choosing the correct power supply is critical for long-term reliability and cost management:

Choose Single-Phase 240V if:

• You have standard domestic-style mains electricity and want to avoid costly three-phase installation.
• The door will operate a moderate number of times per day (e.g., morning opening, evening closing, and occasional use during the day).
• Your opening is up to 6m wide and 4m high (20m² maximum area).
• You want the serviceability advantages of an external chain drive motor.

Consider Three-Phase 415V if:

• The door requires high-frequency operation (20+ cycles per day) or intensive continuous use.
• You have existing three-phase electrical infrastructure in place.
• You require a more compact direct drive motor configuration.

Measuring Guide for SeceuroDoor 77 Traditional (Industrial Motor)

Understanding Ordering Dimensions

The measuring, pricing and ordering dimensions for any electric roller shutter door with an industrial electric motor drive are based on the OPENING WIDTH and GUIDE HEIGHT, excluding the guides for the width and endplates for the height. This measurement principle applies regardless of whether it is a single phase or three phase electric motor system.

Key Measurement Rules:

• OPENING WIDTH (between guides) = Ordering Width
• GUIDE HEIGHT (endplates excluded) = Ordering Height

See measuring diagram below for visual reference.

Traditional Build Installation Considerations

The Traditional build roller shutter door uses heavy-duty steel guides and steel angle profiles for installation, which can all be specified to suit different installation requirements and fixing configurations. This flexibility makes the Traditional build ideal for challenging or non-standard openings.

Overall Width at Endplate Level

The overall width at high level where the endplates are fitted will be wider than the overall guide width, and can be wider still depending on the choice of inboard or outboard motor setup.

The electric motor side with an outboard motor configuration requires more side room than the non-motor side at endplate level. Chain drive or direct drive motor choice will also vary the width required for the motor assembly.

Manual Override Access

The emergency manual override included as standard is positioned on the same side as the motor internally and is accessed directly underneath the endplate. Other positions may be available on request to suit specific site conditions.

Endplate Size Variations

The endplate size will vary depending on the door model and height, and therefore the size of the curtain roll when fully opened and rolled up. Please be aware to check the drive-through height and endplate dimensions if your headroom is critical.

Installation Methods

Face Fit - Behind the Opening (Recommended for Traditional Build Industrial Doors)

Most industrial roller shutter doors are installed to the inside face of the aperture. In a perfect scenario, your daylight opening dimensions are the space between the guides and underneath the endplate dimensions. However, it is important to note that any roller shutter will always have a 'hang down' when opened fully, making the final drive-through height slightly less than the height of the guides.

This hang down is normal and varies on different models depending on the curtain specification and roll diameter. If your opening drive-through height is critical, please speak to us first to determine the best height to order for your specific application.

Reveal Fit - Between the Opening

Some roller shutter doors are installed between the aperture opening (reveal fit), and this is where the electric tube motor roller door arrangement works particularly well, as all components are positioned inboard from the ordering dimensions.

You can install any roller shutter door between an opening, but please note that industrial motor-driven models require some additional steelwork or sub-framing to make them fit between the reveal properly and securely. The Traditional build's adaptable steel guide and angle system makes this easier to achieve than with fixed Continental-style arrangements.
