CE Marking

Dealing with concrete wash water correctly should be an important part of any site plan. And equally important is that the equipment you are using is properly tested. A CE mark is backed up through risk assessment and associated Declaration of Conformity, and a requirement of the Provision and use of Work Equipment Regulations (PUWER) states that the WHOLE assembly is CE marked as an assembly, not just the individual components of the unit.

Where appropriate, BlueRinse equipment is CE marked, offering peace of mind from a safety aspect (both site employees and environmental protection) and protection from costly fines and damage to your company reputation.

Mudtech Tank Division is a subscribing member of the CE Marking Association.
