Confirm the site voltage, phase and frequency when making an enquiry. The electrical requirements depend on the selected motor and controller, so the quotation and installation drawing should identify the required supply. Provide details of any existing control system or equipment interlock that the door must connect to.

The motor, controller and drive arrangement should be selected for the door dimensions, operating duty, speed requirements and control interfaces. Ask for the proposed motor and controller specification, brand where applicable, and spare-parts information. Confirm these details for your quotation rather than assuming all high speed doors use the same system.

Compare frame material and surface treatment against moisture, cleaning agents, corrosion exposure and appearance requirements. Ask SEPPES which frame options are available for the chosen model and have the agreed material stated in the quotation. Material selection should reflect the actual site rather than a generic door description.

Provide the clear opening width and height, indoor or outdoor location, traffic type, opening frequency, available installation space and preferred activation method. Include site photos and the electrical supply details. These requirements define the configuration to be priced and make quotations easier to compare.

Compare PVC roll-up, stacking, spiral and insulated configurations according to traffic, opening dimensions and the working environment. The right choice also depends on sealing, wind exposure, available installation space and controls. Start with the high speed door product range and provide your site requirements for model selection.

Tell SEPPES the temperatures on both sides of the opening, traffic frequency and any condensation or cleaning conditions. Ask which insulated configuration is suitable and request the relevant model data. Insulation performance depends on the curtain or panel construction, sealing and installation, so it should be compared using the proposed specification.

Describe the cleanroom application, pressure differences, cleaning process and required control interfaces. Ask SEPPES to confirm the sealing arrangement, curtain and frame materials, and suitability of the proposed configuration. Any cleanroom performance requirement needs to be checked for the complete installation; a door type alone does not establish the room classification.

Compare the proposed door model, application suitability, technical documentation, installation support, spare parts and warranty terms. Request evidence for certifications and project references relevant to your application. Use a written specification so quotations cover the same opening, controls and operating conditions.

Installation responsibilities should be agreed before delivery. Provide the installation team with the approved model-specific drawings and instructions, and confirm the electrical supply, controls and commissioning arrangements. The installer should have the skills and equipment required for the work; installation effort depends on the door and site.

Tell SEPPES the destination country and any documents required by your project. Ask for the selected model's technical data, installation information, packing details and available certification documents. Requirements should be checked for the actual configuration before the order is confirmed.

Service life depends on operating cycles, the working environment, correct installation and maintenance. Describe daily traffic, operating hours and any dust, moisture or temperature conditions when requesting a quotation. Agree on an inspection and maintenance plan for the selected door rather than relying on a universal lifespan figure.

Required headroom and side room depend on the door model, opening size, drive and installation layout. Send the clear opening width and height, space above and beside the opening, and site photos. Request the model-specific installation drawing before finalizing structural work.
