Contact Our Experts for Global Mobile Coffee Solutions

A precise description of the beverage and planned service helps us assess which coffee backpack configuration may be suitable. The following questions explain which information is useful for product recommendations, quotations, shipping calculations and technical support.

What should I include in my first coffee backpack enquiry?

Please describe the intended application, beverage and required quantity. We also need the delivery destination and requested delivery date to assess availability and transport options.

If you have already selected a model, include the exact product name and the required accessories.

Can I contact you without knowing which model I need?

Yes. You can describe how the coffee backpack will be used instead of selecting a product in advance.

Useful information includes:

• Type of event or venue
• Expected number of mobile operators
• Hot or cold beverage service
• Planned serving or sample size
• Length of each service period
• Distance to the refill station
• Indoor or outdoor application

These details help us compare the available capacities and carrying systems.

Why do you need the exact beverage recipe?

The ingredients influence the required container, tap, cleaning procedure and practical beverage flow. Please state whether the backpack will contain black coffee, coffee with milk, tea, hot chocolate, cold brew or another drink.

Also identify sugar, syrup, milk, plant-based ingredients, spices or other additions that may change the consistency.

Which beverages require an individual compatibility check?

Drinks containing coffee grounds, loose tea leaves, fruit pieces, thick foam, undissolved powder or substantial sediment should be assessed before a system is selected.

These ingredients may collect inside the container outlet, hose or dispensing tap. The finished beverage should generally be filtered and sufficiently fluid.

Can I send the product data for my coffee or prepared drink?

Yes. A product description, ingredient list or recipe can help when the beverage contains milk, syrup, chocolate, spices or other additions.

For unusual recipes, a practical test with the intended beverage may be necessary before a larger order is planned.

Should I specify whether the drink is served hot or cold?

Yes. The serving temperature is important when selecting the container and planning the operating process.

The backpacks use insulation but do not actively heat or refrigerate the beverage. Hot coffee must therefore be prepared at the required temperature, while cold drinks must be chilled before filling.

Which details are useful for hot coffee applications?

Please state the approximate filling temperature, intended service duration and expected surrounding conditions. Also explain whether the backpack will be refilled regularly or used for one longer service period.

For professional hot-drink use, a stainless-steel container is generally preferable because it can be preheated and is suitable for repeated cleaning.

Can I request a backpack for both hot and cold drinks?

Yes. Please identify every beverage that may be used in the system. The selected container, hose, tap and seals must be suitable for the complete planned application.

The beverage path must be cleaned properly whenever the product is changed.

Can one backpack be used for coffee and carbonated beverages?

A pressure-compatible configuration may be considered when the same system will also be used for suitable carbonated drinks. This requires different equipment from a simple gravity-fed coffee backpack.

Please list all intended beverages so that the correct tank, tap and pressure components can be assessed before ordering.

Do I need a pressure pump for normal coffee service?

Prepared still coffee can normally be dispensed by gravity from a suitable configuration. A manual pump or CO2 supply is generally unnecessary when the system is used exclusively for non-carbonated coffee, tea or hot water.

Pressure equipment should only be selected when it is required for another planned beverage or a specifically designed application.

Should I choose a plastic or stainless-steel container?

The suitable material depends on the frequency of use, beverage and budget. A plastic container can provide an economical option for selected applications.

For repeated use with coffee and other aromatic or strongly coloured drinks, stainless steel is generally preferable because plastic may absorb colour or aroma over time.

Which capacity should I request?

The appropriate capacity depends on the serving size, expected demand, walking distance and frequency of refilling.

A larger container reduces refill frequency but increases the loaded weight. A smaller model may be more practical when the wearer must walk for extended periods or can return regularly to a preparation station.

How can I estimate the required beverage capacity?

Multiply the expected number of servings between refills by the planned cup volume. Add a reasonable allowance for test dispensing, spills and beverage remaining inside the container and hose.

The calculation should use the actual planned filling quantity rather than only the nominal container capacity.

Why should I provide the cup size?

The cup volume affects the number of servings per filling and the expected refill interval. It also helps determine whether a cup dispenser is useful for the planned operation.

Please state whether the cups are intended for samples, regular coffee servings or larger takeaway portions.

Which cup measurements are required?

Please provide the cup capacity and outside rim diameter. A photograph or technical drawing can also be useful when the cup has an unusual shape.

Cups with handles, wide rims or strongly tapered sides may not fit the universal cup dispenser even when their nominal volume appears suitable.

Can I send a sample cup for compatibility testing?

A physical sample can be useful when a large quantity of cups will be purchased or when the shape is difficult to assess from measurements alone.

Please contact us before sending a sample so that the delivery and identification details can be coordinated.

What should I state when planning coffee samples?

Please provide the sample cup volume, expected number of recipients and planned duration of each distribution period.

Also explain whether the samples are free of charge, connected to a promotional campaign or combined with product information and customer interaction.

Can I request equipment for paid mobile coffee sales?

Yes. The backpack can be incorporated into a mobile sales concept organized by the customer, caterer or event operator.

Payment terminals, cash systems, staff, coffee preparation and local permissions are not automatically included with the dispensing equipment.

Does Rocket Packs provide baristas or event staff?

No. Rocket Packs supplies the coffee backpack and selected accessories. The purchaser is responsible for beverage preparation, staffing, service and operation at the venue.

The equipment can be used by the customer’s own employees, catering partner, agency or promotional team.

Can I request a complete coffee catering package?

The standard offer covers the mobile dispensing equipment rather than a staffed catering service. Coffee machines, grinders, ingredients, cups and event personnel must be arranged separately.

Please identify the equipment you require so that the product quotation can be prepared clearly.

What information is needed for a professional event project?

For trade fairs, conferences, festivals or promotional campaigns, please describe the planned operating concept.

• Number of service zones
• Required number of operators
• Expected duration of the event
• Length of each mobile shift
• Available coffee preparation facilities
• Location of the refill station
• Expected walking distances
• Required cups and service accessories
• Branding or campaign requirements

This information helps us assess whether several identical systems or a combination of capacities may be appropriate.

Can I request one backpack for a pilot project?

Yes. A single unit can be requested for testing, subject to current availability.

The test should use the actual beverage recipe, cups, staff and refill process planned for the later project. This provides a more reliable basis for deciding on a larger quantity.

Can several models be included in one quotation?

Yes. Different capacities or configurations can be listed separately in one quotation.

Please identify the intended purpose and quantity of each model so that the equipment is not confused during order preparation.

Can I request special hoses, taps or other modifications?

Technical modifications are assessed individually. Please describe the required change, intended purpose and quantity as precisely as possible.

Photographs, drawings or connection details can help us understand the request. Not every modification is technically possible or economical for a small order.

Can branding requirements be discussed before ordering?

Yes. Depending on the model, printed paper graphics can be inserted into transparent display areas on the backpack.

Please identify the preferred model and the surfaces you would like to use. The confirmed dimensions should be obtained before the final artwork is prepared.

Are graphic design and printing included?

No. Graphic design and printed advertising inserts are not automatically included in the standard equipment price.

The customer can normally arrange the design and printing locally using the measurements supplied for the selected backpack.

Can the graphics be changed for different coffee brands?

Yes. Replaceable paper inserts allow the visible design to be adapted for another beverage, campaign, sponsor or event.

This is useful when the same backpack is used for several projects or coffee varieties.

What information is needed to calculate shipping?

For an initial transport calculation, please provide the required quantity, destination country, postal code and city.

A formal quotation requires the complete delivery address. Please also state whether the destination is a company, private residence, event venue, warehouse or freight forwarder.

Why are the billing and delivery addresses required separately?

The invoice recipient and physical delivery destination may be different. Both addresses are required to determine the correct tax treatment, shipping documents and transport cost.

Please label the addresses clearly when submitting the enquiry.

Which company information should be included?

Business customers should provide the complete legal company name and the applicable VAT or registration number.

For deliveries outside the European Union, additional importer or tax information may be requested by the carrier or customs authority.

Can private customers order a coffee backpack?

Yes. Rocket Packs sells directly to private customers as well as companies, agencies, caterers and public organizations.

Private customers should provide their complete billing and delivery address so that VAT and transport costs can be calculated correctly.

Which details are needed for a formal quotation?

Please provide:

• Complete customer or company name
• Billing address
• Delivery address
• Contact person
• Telephone number
• VAT or registration number, where applicable
• Required products and quantities
• Requested delivery date

A quotation can only reflect the correct equipment and total delivery cost when these details are complete.

In which language and currency are quotations issued?

International quotations, pro forma invoices and invoices are normally prepared in English and in euros.

Please submit product names, quantities and address details clearly so that they can be transferred correctly into the documents.

What happens after I accept a quotation?

After the equipment, availability and delivery conditions have been confirmed, a pro forma invoice is issued according to the agreed payment terms.

Order preparation begins after receipt of the required payment. The expected processing and transport period depends on the product, quantity and destination.

Does submitting the contact form reserve the equipment?

No. A product is not reserved merely because an enquiry has been submitted.

Availability and any reservation conditions are confirmed separately in the quotation or order correspondence.

Should I include both the event date and delivery deadline?

Yes. The equipment should arrive before the event so that it can be inspected, cleaned, tested with the intended beverage and adjusted to the operators.

Please state the latest acceptable delivery date as well as the actual event date.

Does an urgent enquiry guarantee delivery before the event?

No. Availability, payment receipt, order preparation, transport and customs clearance can influence the delivery period.

The requested deadline should be stated clearly so that the current possibilities can be checked before the order is confirmed.

Can I collect an order in Frankfurt?

Collection may be possible when it has been agreed in advance and the order has been prepared.

Please do not arrive without an appointment or assume that products displayed online are available for immediate collection.

Can I arrange collection through my own courier?

Collection by a customer-appointed courier or freight forwarder may be possible after the order, payment, packing and collection details have been confirmed.

The customer should provide the transport company with the final carton dimensions, weight and collection reference supplied for the shipment.

Can I visit Rocket Packs to view the products?

A visit must be arranged in advance. Please identify the models or technical questions you would like to discuss so that the relevant equipment can be prepared where possible.

The business location is not a conventional retail shop with every product permanently available for demonstration.

What should I include in a spare-parts enquiry?

Please provide the backpack model, approximate purchase date and original invoice or order reference where available.

Also send clear photographs of the complete component, its connection and the surrounding equipment. This helps distinguish between visually similar hoses, taps, seals and fittings.

How can I identify my coffee backpack model?

Check the original quotation, invoice, product label or operating instructions. If these are unavailable, send photographs of the complete backpack, beverage container, closure, tap and hose connections.

The exterior cover alone may not identify the technical configuration reliably.

What information is useful for a technical support request?

Describe what happens, when the problem occurs and which beverage was used. Please also state the filling temperature, ingredients and cleaning procedure already completed.

Useful supporting material may include:

• Photographs of the complete system
• Close-up images of the affected connection
• A short video showing the beverage flow
• Model and order reference
• Description of the beverage recipe
• Steps already taken to investigate the issue

What should I report when the coffee flows too slowly?

Please state whether the problem occurs with water as well as with the intended beverage. Also describe the recipe, hose position and condition of the tap.

Slow flow may be caused by beverage residue, a kinked hose, solid ingredients, an obstructed outlet or an incorrectly positioned container.

What should I do if hot coffee leaks from the system?

Stop serving immediately and remove the backpack from the customer area. Place it securely before inspecting the container closure, hose and tap.

Do not continue using the equipment until the cause has been identified. Send photographs showing the exact point from which the beverage escapes.

Can a technical problem be diagnosed only by telephone?

Not always. Written information, photographs and videos are often needed because different models and fittings can look similar.

A telephone discussion may support the assessment, but the relevant product and operating details should still be submitted in writing.

Can I send photographs and videos through the contact form?

If the contact form does not support the required attachments, send the initial message first and provide the files by email afterwards.

Use the same name, company and project reference in both messages so that the attachments can be assigned correctly.

Should I send the same enquiry several times?

No. Repeating the same request through the form, email and telephone can create duplicate correspondence.

Send one complete written enquiry and refer to it if a later telephone clarification is required.

What should I write in the email subject line?

A clear subject line should identify the product, quantity and destination or type of request.

Examples include “Quotation request – 5 coffee backpacks – France” or “Replacement tap – Pro 11 litre – Germany”.

What should I check before submitting my message?

Make sure that your email address is correct and that the message contains enough information to understand the request.

• Intended beverage and ingredients
• Hot or cold service
• Required quantity
• Preferred capacity or application
• Cup size
• Requested delivery date
• Destination country and postal code
• Relevant photographs or product references

A complete first enquiry helps us assess the product configuration and delivery requirements without unnecessary follow-up questions.
