Retrofitting existing machinery, particularly in interlinked production lines, is a recurring challenge for specialist plant manufacturers such as us at Walther Trowal. If, following a cost-benefit analysis carried out jointly with the customer, the decision is made to proceed with a Retrofit, we begin the project planning phase to ensure that your requirements and the EU Machinery Directive are met.
This effort is not justified for maintaining the supply of spare parts for smaller machines. In such cases, we offer ready-made Retrofit kits, known as ‘retrofit packages’.
