Weiss Technik UK Ltd

Weiss Technik UK Ltd is part of the Weiss Group, the world's largest manufacturer of environmental testing equipment and one of four divisions of the Schunk Group.

In 2013, following a combined presence in excess of 55 years, two respected leaders in environmental testing solutions, Weiss Gallenkamp and Design Environmental, merged to form Weiss Technik UK.

Weiss Technik are leaders in Environmental simulation systems and our systems deliver world-class standards in terms of design, performance and reliability. Our wide range of equipment is expertly maintained by a nationwide team of factory-trained service professionals - the largest in the UK.  Furthermore, our product specialists can provide a full project management service, from planning and consultation right through to installation and commissioning. The team at Weiss Technik UK understand the critical needs of our customers and we are totally focused on providing innovative and effective solutions. 

Weiss Technik UK Ltd employs a team of over 30 Sales, Service, Technical and customer support staff throughout the UK. We have the largest team of of field service engineers in the industry that are regionally based and factory trained. 

Weiss Technik UK is accredited with ISO 9001:2015 and ISO 14001:2015


Developed through our global experience, this new generation of Pharmaceutical Stability Testing facilities represents leading edge technology from Weiss Technik UK. We have hundreds of chambers in over 50 countries satisfying critical performance standards demanded by the pharmaceutical industry. With the new Pharma-Safe models, further consideration of all aspects of the stability testing process have been incorporated into the design whether that be stability testing, photostability testing, validation, serviceability or cost of ownership.

The Pharma-Safe family is available in sizes to suit every need. From the smallest 182 litre (6.5cu.ft) when demand for test space is small, to the largest Walk-in Room.

Stability Testing by definition is a long process. A Stability Test Chamber must perform reliably and accurately throughout this time. Maintenance or service interventions during the testing are disruptive and costly. The Pharma-Safe system gives you long term, maintenance free, reliable and accurate performance.

All aspects of Pharma-Safe's design are totally compliant with ICH guidelines for Stability Testing (Q1A) and Photostability Testing (Q1B).

Cost of ownership has been minimised by the use of computer controlled refrigeration systems that control the flow of refrigerant gas levels rather than the conventional on/off systems. Water consumption is very low however with the AquaRec UV option it becomes negligible. In today's environment conserving resources counts. Responsible design ensures low utilisation of valuable resources and minimises cost of ownership without compromising performance.

Validation procedures and documents have been developed and refined with input from leading global pharmaceutical companies. You can be confident that the Pharma-Safe validation protocols are recognised by industry leading organisations on every continent and will surpass even the most demanding requirements. Pharma-Safe is a global product for a global industry with personal localised service and support at its heart. Pharma-Safe dealers are trained and certified by Weiss Technik K.

Modular, quick-build Pharmaceutical Stability Test Rooms (PSR) have proven popular. The PSR range provides cost-efficient, large capacity storage for those with high and increasing sample throughput. Offering the same long term, reliable and accurate performance as the rest of the family, PSR's are installed by a dedicated team of specialists ensuring compliance with our strict validation protocols.

Environmental Simulation

Areas of Application

Weiss Technik Product are used in a huge range of applications across most business sectors.

Specific Business Areas are:

  • Aerospace - From the ground to the clouds and into space 

Taking off successfully and landing safely are the most important obligations for the aerospace industry. You can use weisstechnik® environmental simulation systems to simulate all the important parameters in advance. The dimensional accuracy of individual components must be just right to ensure that they fit into the system perfectly. This must also hold true for composite materials with differing thermal expansion coefficients. With our heating technology systems, you can achieve homogeneous shaping results across an entire surface. Our containment and cleanroom systems keep undesired dust particles away, regardless of whether they arise while sanding lacquer, from production processes or when measuring electronics components.

  • Automotive - From gearwheels right through to the bodywork

Across the desert, to Alaska and back, and all that in a lightweight vehicle with the highest possible degree of connectivity. Not a problem using weisstechnik® systems for environmental simulation, heating technology and cleanrooms! We can simulate air flows, altitude, temperature fluctuations, vibrations and pressure, as well as weathering and corrosion behaviour. We shape every material and keep the air clean too! Using our technology, you can carry out measurements with the required level of accuracy.

  • Electronics - From chips right through to supercomputers

The lifecycles of modern electronics are short, and every second counts! By using weisstechnik® environmental simulation systems, you can find out whether your product is resistant to cold, heat, vibrations and dust before its market launch. Quick, gentle drying and hardening of coatings and plastic sleeves are child’s play using our drying and heating cabinets. If your production processes require exact climatic and/or clean conditions, our air-conditioning solutions are the answer. 

  • Engineering - From concrete to plastic.

Materials are used in a variety of production. They have to be safe for humans and the environment, shaped into the correct form, and meet their intended purposes long term. With weisstechnik® systems you can identify the possible evaporation of building materials and parts. In addition to production ovens for moulding, we also offer infra-red ovens, e.g. for manufacturing carpets or treating timber. The dust that this produces doesn’t stand a change with our safety workstations – and in highly critical situations, we offer added explosion protection. 

  • Pharmaceutical - From blister packs right through to cytostatic drugs.

weisstechnik® supplies GMP-compatible and FDA-compliant solutions for the production and packaging of pharmaceuticals and active substances – from stability storage and testing in the development phase, testing of the durability of packaging under tensile stress and sterile filling of packaging, right through to optimal, germ-free production under cleanroom conditions. Our safety workbenches and workplaces provide the necessary protection for both personnel and products

  • Biology - From Arabidopsis right through to vegetables, and everything in between!

From arabidopsis right through to vegetables, and everything in between!

The weisstechnik® Fitotron® range of products includes climatic cabinets and rooms that have been developed especially for scientific investigations in the areas of plant growth, insect growth, tissue cultures, seeds and other microbiological applications. These products can be used in all cases where exact circadian control of both climate and lighting are necessary. We offer solutions that include both series-produced and individual, customised chambers and rooms for universities, public authorities and industry.
