APROVIS manufactures products and builds plants in line with international guidelines and safety standards. We focus entirely on your needs and reliably implement even complex regulations. We respond flexibly to changes on the market to allow you to remain competitive.

First-hand safety

APROVIS has all the relevant certificates that are crucial for exhaust gas and combined heat and power plant technology. Depending on the product and plant in question, we supply the individual components or systems with prescribed safety equipment or, if required, supplement them with your defined additional services.

Pressure vessel

Acceptance of our exhaust gas heat exchangers, steam generators and high-temperature heat exchangers is carried out as per the European Pressure Equipment Directive (PED 2014/68/EU), the ASME Code or the EAC (Eurasian Customs Union). So pressure vessels can also be operated on the North American and Eurasian markets.

Catalytic converters

The Ordinance on Medium-Sized Combustion Plants, Gas Turbine Plants and Combustion Engines (44. BImSchV) is extremely important – especially for SCR catalytic converters. It is the national transposition of the European Medium Combustion Plant Directive (MCPD) and aims to reduce emissions of particulate matter, sulphur dioxide and nitrogen oxide. Since the limits apply to existing and new installations alike, upgrading is a priority issue here.

The most important certificates that APROVIS has are:

ISO 9001:2015:

  • quality management system

  • Module A2 certificate as per PED 2014/68/EU
