I would like to say thank you for allowing the testing off these hoses for 2 months. I got great feedback from the assembly testers and service engineers. I would like to change this order now and keep the 3x HELI-JET 0-15 that are already installed here and order two more on my tooling budget for now.

Conor

Dear Dirk Thank you for your message and we will certainly contact you. You have a nice product package and website.

Remco

Thank you for the reminder. We appreciate your expense, the discussions and the preliminary information on the quote. In our discussions in the last days, we decided to go for a different solution, why we won’t use with the viewport you offered us. I hope, we will have the opportunity to buy from you again in the future.

Aaron

I would like to come back to the company visit that our group made to DEMACO on February 8, 2023. We are now drawing up the program for 2024 and we have reviewed all company visits from the past year. The visit to DEMACO has been designated as the best company visit of 2023. Very interesting and presented with great compassion. A beautiful North Holland company that operates internationally. We would like to thank you again for the welcome and presentations. Would you also like to convey our thanks to Mr Dekker, in particular for the extensive and clear presentation.

Piet

Thanks for your quick reply! 200 C will be completely fine for our application. I think this part will work perfectly, and I plan to order it through your website. I haven’t ordered from your company before, but I’m really impressed by your quick customer service. Thanks again for your help.

Wes

I would like to inform you that we have received the divided vacuum chamber in good condition. We are impressed by the quality of the goods delivered and the care with which the VAT was produced.

Bonjour Dirk Nous vous remercions pour votre message et nous ne manquerons pas de vous contacter. Vous avez un bel ensemble de produits et un beau site web.

Remco

Merci pour ce rappel. Nous apprécions votre dépense, les discussions et les informations préliminaires sur le devis. Lors de nos discussions ces derniers jours, nous avons décidé d’opter pour une solution différente, que nous n’utiliserons pas avec la fenêtre de visualisation que vous nous avez proposée. J’espère que nous aurons l’occasion d’acheter à nouveau chez vous à l’avenir.
