In addition to our broad product portfolio in the field of filter and damper systems, we are your specialised partner when standard solutions are no longer sufficient. Decades of expertise, qualified employees and the direct connection to research and development enable us to develop customer-specific products from development and prototypes through to series production, whether modifications of existing components or entirely new ones. Our strength lies in the individual, or small series production of special components. The new modern production facility in Lower Bavaria offers 5,000 m² of state-of-the-art production machinery for the construction of special components for a wide range of applications and sizes: CNC controlled nibbling and bending machines, a welding robot, longitudinal seam welding machines, TIG and MAG pulse welding, glass bead blasting for austenitic materials and crane systems up to 12 tonnes. Stainless and black steel components are built to EXC2 and EXC3 as a certified specialised welding company, with in-house design calculations, CFD simulations, testing and qualifications, and a QA department acting as the interface with authorities and experts.

Portfolio of special components

Filter walls; container solutions and container design airlocks; additional HVAC systems; external exhaust air systems; building end dampers; isokinetic sampling; drier plants; sealing bulkheads; setting magazines; adjustment baskets and storage baskets; sample containers; overpack; glove boxes and isolators; FFU and AHU for the food industry; filling cabin for the food industry; cooling lines for film production; failure filter and surge relief filter; gas-tight doors; acid-resistant coatings.

Glove boxes and isolators

Sealed enclosures and containers with glove ports are known as glove boxes or isolators. Usually operated at negative pressure to protect personnel and environment, with positive-pressure variants to protect the product. Dimensions and equipment are customised; material stainless steel and glass.

• Stabilised stainless steel with sealed glass front; established glove port systems (e.g. Pedi, Switzerland)
• Rounded corners and smooth surfaces facilitate easy cleaning, decontamination and disinfection; resistant to standard disinfection media
• HEPA or ULPA stages with pre-filter options; monitoring of pressure, volume flow and filter loading; side material airlocks and pass-throughs; viewing window and lighting
• Applications: nuclear laboratories, biological, medical, R&D, industrial sterile processes such as seed propagation and semiconductor

Nuclear decommissioning and remote handling equipment

Krantz offers products and services for nuclear facility decommissioning (see the decommissioning brochure), including mobile and re-cleanable HEPA filter units for dismantling work, remote-controlled in-cell filter systems, gas-tight wall penetrations for measuring, control and regulation lines, and gas-tight doors. For a vitrification plant in China, Krantz is supplying a canister lifting car, weighing device, turntables and gas-tight lead-shielded wall bushings (contract announced November 2025). [Confirm which decommissioning references Krantz is willing to name for the UK market.]

Civil protection and critical infrastructure

Ventilation systems for civil defence and critical infrastructure, covered in the Protection of Critical Infrastructure brochure; components proven to 1,100 °C in extreme heat testing.
